National Weather Service Baltimore MD/Washington DC
923 PM EST Wed Nov 20 2024

.SYNOPSIS…
A strong cold front will move through the area overnight. An
upper level low will circulate overhead through Saturday. An
area of low pressure will track to our northwest through the
Great Lakes early next week. High pressure will build back in
for the middle of the week.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/…
A strong cold front is currently aligned from north to south
from central Maryland to eastern Virginia. Ahead of it and along
it is a broad area of heavy showers and embedded thunderstorms.
As this area of convection passes across Northeast Maryland,
southern Maryland, and the Chesapeake Bay over the next hour or
two, it will bring most areas a quick one-half to one inch of
rain. Occasional lightning strikes, and wind gusts of 45 to 55
mph are also noted to accompany this band of convection.

Winds behind the front and this convection will remain gusty out
of the west-northwest to northwest along with lingering showers
or drizzle. At higher elevations of western Maryland and eastern
West Virginia, rain showers are beginning to mix with and/or
change over to all snow and should continue into much of the
night. Wind Advisories are in effect across the northern half of
the region with Winter Storm Warning and Winter Weather
Advisories in the western mountains and over the Blue Ridge.
A Special Weather Statement also remains in effect for a little
while before expiring later this evening.

Conditions will dry out during the second half of the overnight
east of the mountains, but strong cold advection will continue.
Low temperatures will be in the upper 30s to near 40 for most,
with low to mid 30s in the mountains.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/…
Previous discussion…
Conditions should start to dry out tomorrow, but the boundary
layer will destabilize by the late morning to early afternoon
hours as the core of the upper low approaches from the west.
Snow showers will form within upslope flow to the west of the
Alleghenies during the late morning hours, with additional
showers forming to the east of the mountains during the
afternoon hours. Coverage of showers should remain fairly low to
the east of the mountains, with the bulk of the day remaining
dry. Temperatures will climb up into the 40s to near 50 by
afternoon, but temperatures will decrease rapidly with height as
the upper low moves overhead, so these showers would likely
occur as a mix of rain and graupel to the east of the mountains.

The snow shower activity along and west of the Allegheny Front
will be intermittent, but squally in nature, with multiple short
duration heavy bursts of snow and then dry periods (and even
some sun possible) in between. The snow in the mountains will be
rather light and fluffy tomorrow, as instability extends up
into the dendritic snow growth zone. A few inches will be
possible by tomorrow evening. There will be a bit of a lull in
the activity tomorrow night once daytime heating and resultant
boundary layer instability is lost. Light snow may continue on
and off through the night, and a couple of additional inches may
be possible by Friday morning.

Another disturbance embedded within the much larger upper level
low will rotate in from the north on Friday. The steadiest and
likely heaviest snow in the mountains will occur late Friday
morning through Friday evening as low-level warm advection
overlaps upslope flow intersecting the terrain. Snowfall rates
may approach an inch per hour at times Friday afternoon. The
snow on Friday will be a wetter snow as the column starts to
warm.

Some snow may also occur to the east of the mountains Friday
morning, with the first snowflakes of the year possible in the
DC and Baltimore metro areas. Temperatures will likely be too
warm for accumulations along the I-95 corridor, but some minor
accumulations may be possible along Parr's ridge in north-
central Maryland and in the Catoctins. Any snow to the east of
the mountains should switch over to rain during the afternoon as
temperatures warm.

Precipitation will continue in the mountains through Friday
night. As temperatures continue to warm, some of the lower
elevations in the mountains may switch over to rain before
ending, but the highest elevations (above 2500 feet) should
stay all snow through the night. By the time all is said and
done, 6-12 inches is expected along and west of the Allegheny
Front, with isolated totals of 12-18 inches possible along the
highest ridgetops. Winter Storm Warnings are in effect for
Garrett, western Grant, western Pendleton and western Highland
counties starting at 10 AM tomorrow. Those Warnings continue
through Friday night. A Winter Weather Advisory is also in
effect for western Mineral county from 10 AM tomorrow through 10
PM tomorrow night.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/…
Snow showers will begin to taper off after daybreak on Saturday and
transition to more of a rain/snow mix, and perhaps even over to
freezing drizzle at the highest elevations. Not expecting much
additional snow accumulation beyond early Saturday morning, but
could see at least a few hundredths of an inch of ice accretion on
the ridges. By Saturday afternoon the shortwave will pivot east and
heights begin to rise. This will result in pretty rapid drying out
into the afternoon/evening. Elsewhere, Saturday remains dry with
gusty northwesterly winds of around 25 to 35 mph, with gusts up to
40 mph, mainly on the ridges and over the open waters.

Sunday into Monday look to remain mostly dry as high pressure
returns to the region. Sunday will see highs around the mid 50s,
then increasing to around the low 60s on Monday.

Meanwhile, low pressure over the central U.S will track north and
east into the Great Lakes late Monday into Tuesday. This will send
another front into our region for the middle of next week. As it
stands now, the front looks to stall somewhere in the vicinity of
our region Tuesday into Wednesday. This will lead to increased
precipitation chances during this time. Active weather continues
through the extended could potentially continue into Thanksgiving
and towards next weekend.

&&

.AVIATION /02Z THURSDAY THROUGH MONDAY/…
A strong cold front approaching the I-95 corridor will move east
overnight and across the Chesapeake Bay. Winds have or will
shift to a west-northwest to northwest direction and gust over
40 knots. Heavy rain and embedded thunder will lower ceilings to
LIFR or IFR but visibility should be MVFR to VFR. Showers may
linger for a few hours behind the front before conditions dry
out during the second half of the night. Low level wind shear
will also be possible immediately in the wake of the front this
evening.

Previous discussion…
Prevailing VFR conditions are expected tomorrow. A few mixed
rain/snow/graupel showers may be possible tomorrow afternoon,
but the vast majority of the time should remain dry. Winds will
remain out of the west. Mixed rain and snow may potentially
impact some of the terminals Friday morning. Any precipitation
would change over to plain rain by Friday afternoon.

Gusty WNW winds around 20 to 30 kts will be the main threat to the
terminals on Saturday at the terminals. Otherwise, VFR conditions
are expected as we transition into a period of high pressure that
will then continue into Sunday. Winds turn more westerly on Sunday
and will be around 10 to 20 kts.

&&

.MARINE…
A cold front will cross the Potomac River and Chesapeake Bay
later this evening and overnight. Winds will rapidly shift from
southeast to west-northwest or northwest and gust over 40 knots
in many places. Gale force winds will be imminent in many waters
with a few possible Storm force gusts over the widest waters.
Special Marine Warnings are currently in effect for most of the
northern and central Chesapeake Bay waters and Potomac Basin.
Some thunder may be possible in association with the squall
line. Winds gradually decrease late tonight into tomorrow
morning, but Small Craft Advisory conditions will continue
through Thursday and Friday. Gusts may near low- end Gale levels
Friday afternoon into Friday night.

In the wake of a strong cold front, high-end SCAs will continue
through much of the day Saturday. Gale conditions may even briefly
be possible early Saturday.

Winds taper off into Sunday, but SCAs seem likely to continue,
albeit closer to the low end.

&&

.TIDES/COASTAL FLOODING…
Minor coastal flooding is possible at the more sensitive tidal
sites like DC SW Waterfront with the tide cycle this evening.
Water levels will decrease tonight through the upcoming weekend
as winds turn westerly.

Wakefield Area Forecast Discussion

AREA FORECAST DISCUSSION
National Weather Service Wakefield VA
143 AM EST Thu Nov 21 2024

.SYNOPSIS…
A strong cold front moves across the area late tonight into
Thursday, bringing colder, drier air and blustery NW winds
through the late week period into the upcoming weekend. High
pressure will build back into the region by the end of this
weekend keeping the region dry.

&&

.NEAR TERM /UNTIL 7 AM THIS MORNING/…
As of 730 PM EST Wednesday…

Key Messages…

– A strong cold front moves across the region tonight into
Thursday morning. Showers with a few embedded tstms prevail
this evening, lingering into early morning to the E.

– Strong, gusty NW winds develop post-frontal, with gusts up to
30-40 mph (locally higher across the eastern shore where a
Wind Advisory is in effect).

The latest analysis indicates the sfc cold front located along a
line from near LKU to DAN, with strong gusty NW winds
immediately in the wake of the boundary. Showers have been most
prevalent across NW and SE portions of the FA, with the
coverage more scattered across central VA. Elevated tstms are
primarily located over N-NW portions of the CWA. It remains very
warm for a late November evening, with temperature as of 8 PM
still mainly in the lower 60s.

The timing of the front based on latest trends is for the wind
shift to arrive between 9-10pm W of I-95, pushing to the coast
between 11pm and 1 am. Immediately in the wake of the front, there
will be a brief period of wind gusts between 30-40 kt across
most of the area, with 35-45 kt across Delmarva. With decent
model guidance a wind advisory is needed for the area. There is
also the possibility of these wind gusts knocking down trees and
branches across the region. These conditions will be brief and
last between 1 to 3 hours. Once the frontal passage moves
through these conditions will die down slightly but winds will
still remain breezy until closer to sunrise when they diminish
further.

Skies are expected to clear and weather conditions will remain
breezy behind the frontal passage. With these clearing skies and
cooler and drier air being advected into the area, overnight low
temperatures are expected to drop to the mid 30s to around 40F W
of I-95, with 40-45F to the E.

&&

.SHORT TERM /7 AM THIS MORNING THROUGH FRIDAY NIGHT/…
As of 325 PM EST Wednesday…

Key Messages…

– Gusty NW winds continue Thursday and Thursday night. NW winds average
15-20 mph with gusts to 25 to 30 mph (highest coastal areas).

– Blustery and much cooler weather conditions behind a strong
cold front Thursday-Friday night.

The strong trough will continue to hang around the area through
the early portion of this weekend. This allows the area to
start drying out Thursday with the persistent northwesterly
flow. There will be multiple shortwaves transversing along the
trough allowing multiple reinforcing shots of cooler air. The
first of these push through Thursday evening, bringing additional
gusty winds, some clouds and perhaps a few showers along the
eastern shore. Otherwise expect most of the area to remain dry.
Highs only top out in the 50s Thursday. Winds do decouple a bit
inland later Thu night, which will make for a stark temperature
contrast between inland areas and the coast. Look for lows in
the upper 20s to low 30s inland, with mid to upper 30s along the
coast. The second shot comes Friday and could potentially be
cooler than Thursday with highs in the upper 40s across the
Piedmont and lower 50s along the coast. The latest models depict
the core of the upper low across eastern PA and NJ, with a
rather strong shortwave diving SE across the eastern shore.
Expect a good chance for showers Fri aftn into Fri night on the
eastern shore, with much lower PoPs for light showers or just sprinkles
more favored along and to the S of the I-64 corridor. With the
additional cloud cover, Friday evening/night, low temperatures
only cool down in the upper 30s and lower 40s.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/…
As of 325 PM EST Wednesday…

Key Messages…

– High pressure moves back in bringing dry weather back across the
region over the weekend into early next week.

Into the weekend and early next week the latest 20/12z ensemble
guidance is in decent agreement with the synoptic pattern. The upper
level trough will begin to move out of the area by saturday and
sunday allowing a ridge to take its place. This will allow
temperatures to warm up into the middle 50s to around 60. The breezy
conditions will taper off late Saturday into Sunday as the trough
moves out of the region. Temperatures next week are expected to warm
a little next week as the high moves off the coast with highs
warming back into the upper 50s to around 60s on Monday, with highs
in the lower 60s by midweek. Early morning lows warm back into the
40s Tuesday and Wednesday mornings. Rain chances return to the
forecast next Wednesday ahead of the next system arriving from the
NW. Will note, by the middle of next week the ensembles do disagree
with the placement and strength of the next system. However, they do
agree on a potential system and Pops remain tn the forecast and stay
between 15-25%.

&&

.AVIATION /07Z THURSDAY THROUGH MONDAY/…
As of 140 AM EST Thursday…

The well-advertised strong cold front swept across the region
earlier this morning, bringing gusty winds, showers and variable
CIGs to area terminals. Conditions continue to gradually improve
in the wake of the front, with a gradually clearing sky expected
over the next few hours. CIGs have already returned to VFR
inland, with MVFR lingering along the immediate coast from ECG
to SBY through 07-09z/2-4 AM EST before returning to VFR. NW
winds will average 10-15 kt through around and just after
sunrise, then increase and shift to the W at 15-18 kt with gusts
to around 25 kt from late morning through early evening.
Increasing aftn clouds are expected, but CIGs should remain VFR,
averaging 6-8 Kft AGL.

Outlook: Gusty W-NW winds continue Fri-Sat, with less wind by
Sunday. Scattered to numerous showers and flight restrictions
are expected across N/NE sections of the area Friday aftn/Fri
night.

&&

.MARINE…
As of 345 PM EST Wednesday…

Key Messages:

– A Gale Warning has been issued for all local waters tonight due to
strong NW winds behind a cold front.

– Another period of Gale conditions is increasingly likely Friday
afternoon through Friday night.

Current surface analysis shows high pressure well offshore the
southeast coast and low pressure over the Great Lakes, with a
stationary front draped across the area and a cold front dragged
across Ohio to Georgia. Winds are generally SE around 5 kt becoming
S 10-15 kt ahead of a strong cold front. This front will quickly
push through the area tonight crossing coastal waters 10PM to 1AM
Thursday. Confidence is strong in Gale force winds behind the front
as cold air moves in behind the front. Winds will abruptly become NW
30-35 kt with gusts up to 50 kt across all coastal waters. As such,
Gale Warnings have been issued across all waters beginning at 10PM
tonight. The strong winds will quickly subside to 20-25 kt behind
the initial surge. A short period of sub-SCA conditions is possible
Thursday, but then winds will ramp back up to at least SCA
conditions Thursday night with winds W at 25-30 kt with gusts up to
30 kt across all waters as a weak trough moves over the area. Winds
will be sub-SCA conditions Friday, but a stronger trough will
increase winds Friday night to W at 25-30 kt with gusts up to 35 kt
in the Bay and 40 kt over the coastal waters. There is high
probability (>80%) for wind gusts greater than 34 kt Friday night,
but will wait for future model guidance to determine in Gale
headlines are necessary for this surge. Winds will then remain sub-
SCA conditions for the weekend and early next week.

Waves and seas are currently 1-2 ft this afternoon and will increase
behind the front to 3-5 ft tonight (locally higher is possible).
Waves and seas will decrease Thursday to 2-4 ft in the Bay and 2-4
ft in the coastal waters. A ramp up along with the winds Friday is
expected with waves 3-5 ft and seas 4-6 ft.

…Back-to-back powerful Pacific storm systems to impact the West
Coast through the end of this week with heavy rain,
life-threatening flooding, strong winds, and higher elevation
mountain snow…

…Heavy snow is likely throughout parts of the central
Appalachians beginning on Thursday, with a separate burst of
snowfall possible across northeast Pennsylvania and neighboring
regions of the Northeast Thursday night into Friday…

An active pattern remains in place this week as multiple systems
bring heavy rain, life-threatening flooding, and higher elevation
mountain snow to the West and the season's first heavy snowfall to
the Appalachians over the next couple of days. In the West,
back-to-back systems from the Pacific and an accompanying strong
Atmospheric River will bring waves of very heavy rain and high
elevation snow to the Pacific Northwest/northern California, with
the first wave continuing through Wednesday evening into early
Thursday and a second wave peaking Thursday night. The most
intense, heavy rainfall will focus on northern
California/southwestern Oregon, with a Moderate Risk of Excessive
Rainfall (level 3/4) in place along the northern California coast
through Thursday morning where the heaviest amounts and greatest
chance for flooding is expected. A broader Slight Risk (level 2/4)
extends inland along the northern Sierra ranges. The second wave
Thursday evening is expected to bring even more intense rainfall
on top of already saturated soils, with a High Risk (level 4/4) in
place along the northern California coast and a Moderate Risk
inland along the northern Sierra ranges. Storm total rainfall may
reach as high as 12-16", with dangerous flash flooding, rock
slides, and debris flows likely. In addition, heavy wet snow is
expected for the Cascades and far northern California. Snowfall
rates of 2-3"/hr and wind gusts up to 65 mph will result in
whiteout/blizzard conditions and near impossible travel at pass
level. Snowfall will increasingly focus at higher elevation in
northern California as snow levels rise ahead of the continued
mild, very moist inflow of Pacific air. Moisture will also spread
further inland bringing lower elevation rain and high elevation
mountain snow to the northern Great Basin and northern Rockies
through Friday. Some locally heavy snowfall totals are most likely
in the mountains across central Idaho and along the U.S/Canadian
border.

To the east, another low pressure system will track eastward from
the northern Plains into the Great Lakes region this evening,
sweeping a trailing occluded/cold front and a line of showers and
thunderstorms eastward through the Appalachians, Mid-Atlantic, and
settling into the Northeast by Thursday morning. Meanwhile, a
broad area of precipitation continues behind the system under the
influence of a deep upper-level cyclone, expanding eastward in
tandem with the low pressure system. Heavy snow and blizzard
conditions over the northern Plains will wind down through this
evening as a wintry mix picks over the Great Lakes overnight
Wednesday and into the day Thursday. Some light to moderate
accumulations are expected, most likely in vicinity of Lake
Michigan. Then, rainfall over New England southwest through the
interior Northeast and into the Appalachians will begin to change
over to snow for higher elevations as the upper-low moves eastward
over the region. Winter weather-related Warnings/Advisories have
been issued through the northern and central Appalachians as heavy
wet snowfall accumulations are expected through Thursday night and
into the day Friday. Winds across the region will also be rather
blustery.

Elsewhere, conditions will be mostly dry with the exception of
some possible showers/thunderstorms for south Florida Wednesday
evening. Cooler more seasonable Fall temperatures will return to
much of the eastern U.S. following the cold front passage, as
highs drop from the 60s and 70s for many locations Wednesday to
the 40s and 50s Thursday. In contrast, the West will see rising
temperatures as a ridge builds northward over the region, with
highs running generally 5-15 degrees above average through the end
of the work week.

WPC Extended Range Forecast

Extended Forecast Discussion
NWS Weather Prediction Center College Park MD
158 AM EST Thu Nov 21 2024

Valid 12Z Sun Nov 24 2024 – 12Z Thu Nov 28 2024


…Overview…

A quieter overall weather pattern can be expected going into Sunday
after the prolonged atmospheric river event in the short range
period, and improving conditions for the Northeast after the low
pressure system departs. The upper level flow pattern then becomes
more quasi-zonal for the Sunday to Monday time period with the
Western U.S. trough moving quickly inland and becoming less
amplified. However, there will still be enough moisture to produce
moderate to locally heavy snow from the Sierra to the central and
northern Rockies, and lingering light to moderate rain for the
lower elevations of the West Coast. A surface low is forecast to
develop across the Plains with a much colder airmass moving in
across the Dakotas and Montana early to mid next week, and an upper
level trough likely builds back in across the north-central U.S.
by Wednesday.

…Guidance/Predictability Assessment…

The 00Z models remain in decent synoptic scale agreement with the
pattern, including the exiting large upper/surface low pressure
system across New England and into southeastern Canada. A blend of
the latest 12Z/18Z deterministic models worked well as a starting
point for Sunday into Monday, with slightly more weighting to the
GFS/ECMWF. The main difference noted for the second half of the
forecast period is that the CMC lingers the trough near the Pacific
Northwest much longer than the more progressive ECMWF/GFS
locations by midweek, and therefore the CMC is also out of phase
across the Rockies and western High Plains by midweek, so it was
not used beyond Tuesday. Overall model spread increases even more
by Thanksgiving with the overall trough evolution across the Plains
and the downstream flow across the Eastern U.S., so forecast
confidence is below average for Days 6 and 7. The ensemble means
accounted for about 50-70% of the forecast blend for the Wednesday-
Thanksgiving time period amid growing model spread.

…Weather/Hazards Highlights…

There will be some abatement in the atmospheric river across
California going into the weekend as the attendant cold front
moves inland and the moisture flux anomalies decrease some,
although there may be some resurgence of moisture directed towards
the northwestern California Coast on Monday. Right now the plan is
to not have any risk areas in the Excessive Rainfall Outlook given
the model differences regarding placement of highest QPF, but a
Marginal Risk area could be needed later. Snow levels will be
dropping in the wake of the front, and this is expected to result
in heavy snow for the higher elevations of the Sierra Nevada, where
1-3 feet of snow is possible for the higher elevations, and
moderate snow for the Intermountain West ranges and eventually the
central and northern Rockies going into early next week.

Improving conditions are also forecast for the Eastern U.S. as the
strong low pressure system moves away from the region. However, the
developing low pressure system over the south-central U.S., in
combination with a frontal boundary, may result in another round of
organized rain going into Wednesday across the Mid-South and into
Kentucky. There has been an upward trend in QPF compared to the
previous forecast.

Temperatures are expected to slowly moderate to near average across
the Eastern U.S. over the weekend compared to the rather chilly
conditions late this week. There is still the potential for Arctic
air to reach portions of Montana and into North Dakota next week
with highs in the 10s and low 20s, and overnight lows near zero
close to the Canadian border based on the latest NBM guidance.
There is still some uncertainty on how far south this arctic
airmass gets, so this will be refined in future forecasts. Warm
conditions should continue from southern Texas to Florida, with
highs in the 70s and 80s.

.SYNOPSIS FOR MID ATLC WATERS…A strong cold front will move E
across the area tonight into Thu. Developing low pressure will
track E across the northern waters tonight into Thu night while
lifting a warm front N across the northern waters. A series of
secondary cold fronts or low pressure troughs will move E and SE
over the region Thu night into Sat night as high pressure slowly
builds E towards the area. The high will then gradually move
offshore Sun and Sun night, then pass E of the region Mon and Mon
night as another cold front approaches the area from the W.

Tropical Weather Discussion for North America, Central America
Gulf of Mexico, Caribbean Sea, northern sections of South
America, and Atlantic Ocean to the African coast from the
Equator to 31N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.

Based on 0000 UTC surface analysis and satellite imagery through
0500 UTC.

…SPECIAL FEATURES…

Gulf of Mexico Gale Warning:
A 1025 mb high currently over southern Texas is building southward,
supporting fresh to strong northerly winds and very rough seas
across the western Gulf of Mexico. Offshore from Veracruz, winds
are peaking at strong to gale-force, while seas are ranging
between 9 and 12 ft. These hazardous marine conditions will
persist until early Thursday morning. Both winds and seas will
gradually subside starting late Thu morning. Please refer to the
High Seas and Offshore Waters Forecasts issued by the National
Hurricane Center at websites:
https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml and
https://www.nhc.noaa.gov/marine/offshores.php for more information.

…MONSOON TROUGH/ITCZ…

Most of the monsoon trough remains over the African Continent. An
ITCZ stretches westward from just offshore of northern Sierra
Leone to 06N34W, then turns northwestward to 11N42W. Scattered
moderate convection is up to 180 nm along either side of the ITCZ
east of 39W. Numerous moderate to isolated strong convection is
flaring up near the western end of the ITCZ from 08N to 14N
between 39W and 43W.

The eastern end of the East Pacific monsoon trough is triggering
isolated thunderstorms across the Caribbean waters near Panama.

…GULF OF MEXICO…

Please read the Special Features section about a Gale Warning
near Veracruz.

A cold front curves southwestward from near Naples, Florida across
northwestern Cuba and the Yucatan Channel to the Yucatan
Peninsula. Patchy showers are seen across the Florida Straits and
Yucatan Channel, including the Florida Keys. Moderate to fresh NW
to N winds and seas of 4 to 6 ft are present at the Florida
Straits and Yucatan Channel. Outside the Gale Warning area, fresh
to strong NW to N winds with 6 to 10 ft seas prevail for the rest
of the Gulf, including the Bay of Campeche.

For the forecast, fresh to strong N winds and very rough seas will
persist behind the front through the night. Afterward, high
pressure will build in the wake of the front with marine
conditions gradually improving across the Gulf from west to east
through the end of the week. The high pressure will become
centered over the northeastern Gulf early Sun, sustaining gentle
to moderate SE to S winds over the eastern Gulf, and moderate to
locally fresh SE to S return flow over the western Gulf.

…CARIBBEAN SEA…

Convergent southerly winds to the south of a cold front over the
Yucatan Channel are causing scattered showers and isolated
thunderstorms south of western Cuba. A modest surface trough is
generating patchy showers between Jamaica and Haiti. Refer to the
Monsoon Trough/ITCZ section for additional weather in the
Caribbean Sea. Moderate to locally fresh NW winds and seas of 3 to
5 ft are present across the waters adjacent to the Yucatan
Peninsula and Channel. Light to gentle winds with 1 to 3 ft seas
are noted north of Costa Rica and Panama. Gentle to moderate ENE
to SE winds and seas at 3 to 4 ft prevail elsewhere in the
Caribbean Sea.

For the forecast, the cold front will continue southeastward and
reach from central Cuba along 80W to the Gulf of Honduras by Thu
morning. It will then reach from eastern Cuba to near Cabo
Gracias a Dios, Nicaragua by Fri morning, and from the Windward
Passage to near the Costa Rica-Panama border Sat morning, where
the front should stall and gradually dissipate. Fresh to strong N
winds and building seas will follow the front through Sat before
winds begin to veer quickly NE to E and diminish modestly.

…ATLANTIC OCEAN…

A cold front curves southwestward from the north-central Atlantic
across 31N45W to 27N60W, then continues as a stationary front to
28N70W. Patchy showers are found up to 50 nm along either side of
this boundary. To the southeast, a surface trough runs
northeastward from near the northern Leeward Islands to 28N46W.
Patchy showers and isolated thunderstorms are occurring up to 100
nm along either side of this feature. Farther east, convergent
southerly winds are producing scattered moderate convection
north of 23N between 38W and 43W. At the Tropical Atlantic,
another surface trough is inducing scattered moderate convection
from 09N to 16N between 44W and 51W. An upper-level low near
31N21W continues to trigger isolated thunderstorms near the Canary
Islands. Refer to the Monsoon Trough/ITCZ section for additional
weather in the Atlantic Basin.

Moderate to fresh with locally strong SW winds and seas at 4 to 7
ft are evident north of 28N between 72W and the Florida-Georgia
coast. Farther east near the cold/stationary front mentioned
earlier, moderate to fresh SW to W winds and 6 to 9 ft seas in
large NW swell dominate north of 26N between 35W and 72W. To the
south from 16N to 26N/28N between 35W and the Bahamas/Leeward
Islands, gentle E to SSE winds with 5 to 7 ft seas in moderate
northerly swell exist. Gentle to moderate with locally fresh
southerly winds and 4 to 6 ft seas prevail for the remainder of
the Atlantic Basin.

For the forecast west of 55W, the cold front will shift north of
the area through early Thu, ahead of a stronger front entering
the waters off northeast Florida tonight, followed by fresh to
strong NW winds and moderate to rough seas. The front will reach
from 31N74W to central Cuba by Thu morning, from 31N68W to
eastern Cuba by Fri morning, and from 31N61W to near the Windward
Passage on Sat morning. The front will stall in that general
vicinity and gradually dissipate through the end of the weekend.
Expect fresh to strong winds and building seas on either side of
the front north of 25N.
