.SYNOPSIS...
A cold front will slowly progress eastward across the region
through Tuesday, then pull offshore Tuesday night. High pressure
will follow briefly for Wednesday. A potent cold front is expected
to move southeast from the eastern Great Lakes to and across the
Mid-Atlantic late in the week. High pressure will likely follow
through the upcoming weekend.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
Several arms of convection are spiraling around the closed upper
low over the middle Ohio Valley. Severe weather risk appears to
be rapidly declining as surface based instability decreases. A
cell or two could perk up near severe levels since what
instability remains is located through the hail growth zone.
However, the Severe Thunderstorm Watch will likely be cancelled
early. Remaining showers gradually pivot northeast, with most of
the forecast area dry by sunrise. Low clouds and fog may develop
over parts of the area tonight. Lows will range from the mid 40s
west (few clouds, west of cold front) to mid 50s and lower 60s
east.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH WEDNESDAY NIGHT/...
Upper low will be lifting into PA Tue with main focus of t-storm
activity shifting more to the east, but still with sct showers
and/or t-storms possible. With less instability available,
severe wx risk seems lower. Trough axis will shift east of the
area late Tue night with drying expected.

Shortwave ridging will build in Wed afternoon and evening
supporting generally fair weather, although isolated to widely
scattered showers or sprinkles can`t completely be ruled out.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
A cut off upper level low will be exiting the regions towards New
England on Thursday as another closed low and upper level trough
pivot towards and across the region on Friday. The upper level
trough will push a cold front through the forecast area on Thursday,
with the front forecast to be located draped across the Carolina`s
on Friday. The proximity of the front will lead to daily
shower and thunderstorm chances to end out the work week.

For the weekend, high pressure from the northwest builds over the
region. Primarily dry conditions can be expected Saturday and
Sunday, however, a stray shower cannot be ruled out each afternoon
during peak daytime heating.

Temperatures on Thursday will be in the 70s for most with those at
higher elevations staying in the 60s. In the wake of the cold front
on Friday, high temperatures will be 60s (50s mtns) with only those
in the southernmost portions of the area and in the metros reaching
the 70s. Temperatures gradually warm over the weekend under high
pressure with highs on Sunday reaching the mid to upper 70s.

&&

.AVIATION /02Z TUESDAY THROUGH SATURDAY/...
Convection is gradually lifting north of the terminals, although
a second round of lighter showers could occur after midnight in
some locations. A thunderstorm could also pass west of CHO in
through 03Z. MVFR to IFR ceilings will likely spread back into
the area tonight, though there is some uncertainty on the
southwestward extent (highest confidence at BWI/MTN). Some fog
may also develop but will be dependent on cloud cover. Any
ceiling/visibility restrictions will likely lift by 14Z.

Less convective coverage expected Tue. Fair weather Wednesday.

Showers and thunderstorms may lead to sub-VFR conditions on
Thursday and Friday as a cold front approaches and moves through
the area. Outside of any precipitation, VFR conditions are
expected across all terminals both Thursday and Friday.

&&

.MARINE...
Convective and local scaled enhanced winds seems to be winding
down this evening, although marginal advisory conditions will
continue on the middle bay through around midnight. A few
thunderstorms remain possible through around 2 AM.

Thunderstorm coverage will be more scattered on Tuesday, with
the highest chance across the northern waters. South winds
Tuesday shift to the west Tuesday night.

Northwest winds are expected both Thursday and Friday in the wake of
a cold front. Winds will likely stay below SCA criteria on Thursday.
Winds near but are expected to stay below SCA criteria Friday
afternoon.
