Synopsis
Periods of rain, possibly heavy at times today late today
through early Thursday, will be followed by drier and cooler
weather into the weekend. A cold front will cross the coast
Monday night, bringing a surge of cooler air next Tuesday and
Wednesday.

Near term through tonight
As of 300 am Wednesday... Only scattered to isolated patches of
light rain and drizzle remain over the area this morning as
isentropic lift has all but shut off. More concentrated activity
resides inland. This lull will persist for a few more hours
before moisture and lift increase with developing low pressure
across the florida panhandle. This system will move up the coast
later tonight with some heavy rainfall possible. The quick
moving nature of the system and tepid rainfall amounts from the
previous system precludes the need for a flash flood watch. Some
indication of a similar severe setup as early Tuesday morning
along coastal areas but this should be more for daytime hours
Thursday. Temperatures will move little today struggling to
reach the 50s. Similar story for tonight and readings may even
rise a bit along the coast late.

Short term Thursday through Friday night
As of 300 am Wednesday... A closed mid upper-level low will lift
across the ohio river valley Thursday. Deep moisture from the
gulf of mexico will surge northward across the carolinas ahead
of this feature. Upper-level diffluence will enhance lift
primarily on the west side of the surface front to produce
widespread rainfall through at least midday Thursday. Current
qpf projections are for areal average of 1-1.5" inches of rain
over most of the forecast area daytime Thursday. The quasi-
stationary frontal boundary will waver along the coast as a
surface low rides up the coastline Thursday morning, and
depending on exact timing and location, portions of coastal
counties may experience a predawn surge in temps before the low
moves north and winds become northwest. SPC continues a marginal
risk of severe weather over far eastern areas Thursday morning
for possible damaging winds and isolated tornadoes. Rain will
taper off from southwest to northeast Thursday afternoon, with
high temperatures ranging from around 50 inland to the mid upr
60s at the beaches. Again, depending on exact location of the
front Thursday morning, the high temperatures along the coast
may be realized in the early morning. The atmospheric column
will dry out rather abruptly Thursday afternoon above 850 mb,
but lingering low-level moisture is expected to result in some
low cloudiness hanging on well into Thursday night, before
beginning to clear west to east before dawn Friday.

Long term Saturday through Tuesday
As of 300 pm Tuesday... Zonal flow aloft will usher surface high
pressure from the gulf coast states into the area Saturday.

Sunday into Monday, the high will slide off to the northeast as
a trough digs across the great lakes and into the mid-atlantic
region. High temps by Sunday and Monday should reach the low-mid
60s before a cooler airmass arrives Monday night, setting the
stage for highs in the mid-upper 50s for Tuesday. See no
significant chance for precipitation during the period.

Aviation 08z Wednesday through Sunday
As of 06z... Ifr to in some cases MVFR (inland) are prevalent
across the area via primarily low ceilings. Some light rain and
drizzle is persisting as well. Guidance is in good agreement on
less coverage of rainfall for the next several hours. Ifr
conditions will persist however and any sites that are currently
MVFR or evenVFR should drop down in short order. More
significant rain redevelops once again from southwest to
northeast late in the period.

Extended outlook... MVFR ifr continuing through Wed and thurs
as another low pressure system lifts across the southeast
through mid week, leaving unsettled weather. Drier,VFR
conditions Friday into the weekend.

Marine
As of 300 am Wednesday... Winds and seas now increasing quickly
across the waters with 41013 reporting 23 knots with five foot
seas. This will be the story for the near term as the northeast
flow only increases further to a range of 25-30 knots. There
could be a few gusts into gale criteria but will hold with the
small craft advisory for now. Significant seas will increase
from the current 4-6 feet to a healthy 6-8 feet by early
Thursday.

Surface low pressure slides up through the area Thursday morning,
with south east winds early in the day becoming out of the west
by late aftn Thursday night. Although seas should drop off to
below 6 ft by this point, winds with frequent gusts to 25 kt
will continue through early Fri morning, so the small craft
advisory will remain in effect.

Weakening NW winds Friday will become more northerly Saturday
and Sunday, and the pressure gradient will weaken as the high
settles just north of the waters.

Ilm watches warnings advisories
Sc... None.

Nc... None.

Marine... Small craft advisory until 1 pm est Friday for amz250-252-254-
256.
