.DISCUSSION...
KEY MESSAGE 1...Freeze Warnings have been issued for the majority
of the area tonight. Additional Freeze Watches have been issued
for Wednesday night.

A reinforcing cold front will move through the area this
morning. Gusty northwesterly winds behind the front will
transport cooler air into the region. High temperatures are
expected to be in the upper 40s to mid 50s for most, with upper
30s in the mountains and near 60 in Central Virginia. There will
be plenty of sunshine, but northwesterly winds gusting to around
20-30 mph will make it feel even cooler.

High pressure builds to our north tonight, as even cooler air
advects in from the north and east. Temperatures are forecast to
drop into the 20s to the west of I-95, with lower 30s further
east. As a result, Freeze Warnings have been issued tonight for
all zones where the growing season is in effect, except Calvert
and St. Mary`s Counties. No frost is expected tonight with
winds staying up through the night.

High pressure will build over New England on Wednesday, and then
offshore Wednesday night. A surface ridge will extend
southwestward over the Mid-Atlantic. Sunny skies are expected
once again on Wednesday, with high temperatures generally in the
50s. With the surface ridge overhead, the pressure gradient
will be much weaker Wednesday night, which should allow for
winds to go calm and create ideal conditions for radiational
cooling. Temperatures are forecast to drop back into the lower
to mid 30s Wednesday night. Freeze Watches have been issued
where the growing season is in effect, minus the inner
DC/Baltimore Metros and Southern Maryland.

KEY MESSAGE 2...Dry conditions will continue through the week.
Temperatures will remain below normal through Wednesday, before
a warming trend ensues through the end of the week.

High pressure will build over the Great Lakes today, to our
north tonight, over New England Wednesday, and then offshore for
the end of the week. This will result in a prolonged stretch of
dry conditions locally. Temperatures will run below normal today
into Wednesday behind a reinforcing cold front. As high pressure
moves offshore, winds will turn out of the southeast on
Thursday, and then south on Friday, leading to a warming trend
in temperatures. Following highs in the 50s on Wednesday,
temperatures should reach into the 60s on Thursday, and then 70s
for Friday into the weekend.

.AVIATION /07Z TUESDAY THROUGH SATURDAY/...
VFR conditions are expected at the terminals through the end of
the week. Winds will likely gust to 20-30 knots out of the
northwest through the day today, before decreasing in magnitude
and shifting to out of the northeast tonight. Light east to
southeasterly winds are expected tomorrow. Southeast winds
continue on Thursday, before turning out of the south on Friday.
Winds may turn out of the northwest on Saturday as a dry cold
front moves through the area.

&&

.MARINE...
SCAs are in effect today within northwesterly flow. Gusts to
around 20-30 knots are expected through the day. Winds begin to
decrease tonight, but SCA gusts may linger over the wider
waters of the Bay through much of the night as winds shift to
out of the northeast. Sub-SCA level winds are expected Wednesday
through Saturday. Winds will generally be out of the east to
southeast on Wednesday, southeast on Thursday, south on Friday,
and northwest on Saturday.

&&

.FIRE WEATHER...
No precipitation is expected across the forecast area through
the week as a drier airmass works in from the northwest. Today
appears to be the most threatening fire weather day of the week,
with northwesterly winds gusting to around 20-30 mph and RHs
dropping into the 20s for most, and potentially even the teens
across Central Virginia. Conditions will remain dry on Wednesday
with min RHs in the 20s, but winds will be lighter and out of
the southeast. Continued lighter winds are expected for Thursday
and Friday, with min RHs forecast to be in the 30s and 40s.
