.DISCUSSION...
KEY MESSAGE 1...Primarily dry conditions are expected through
the week, with cool temperatures to start, followed by a warming
trend late in the week.

An upper-level disturbance will move across the Eastern Great
Lakes and drag a secondary cold front across the region this
afternoon. A few rain showers could develop along this front in
the Alleghenies or across northern Maryland. Elsewhere, dry
conditions with a mix of sun and clouds are expected across the
region. Temperatures will be much cooler than yesterday, but
still close to normal for early April, with highs generally in
the upper 50s to mid 60s (upper 40s mountains). Winds will gust
to around 20-25 mph out of the northwest, making it feel a bit
cooler. Winds will go light for a time this evening, before
picking up again late in the night as a reinforcing cold front
moves through the area. Low temperatures will be in the mid 30s
to mid 40s for most, with upper 20s to low 30s in the mountains.

High pressure will build to our north over the Great Lakes
Tuesday, leading to mostly sunny skies. Temperatures will run
about 10 degrees below normal, with highs for most in the upper
40s and 50s (upper 30s to low 40s mountains). A northwesterly
breeze of around 20 mph will make it feel even cooler. High
pressure will become centered to our north over the Southern
Tier of NY Tuesday night, with a surface ridge extending
southward into our area. Skies will be clear, and winds should
go light or calm, setting the stage for an ideal radiational
cooling night. Temperatures are forecast to drop below freezing
to the northwest of I-95, with lows in the 20s for many. We may
be issuing Frost Advisories and Freeze Warnings for Tuesday
night into early Wednesday in some parts of our region.

High pressure will progress offshore for Wednesday, Thursday,
and Friday. As winds turn southeasterly in response, a warming
trend in temperatures is expected through the end of the week,
with forecast highs generally in the 50s on Wednesday, 60s on
Thursday, 70s on Friday, and potentially nearing 80 this
weekend.

.AVIATION /14Z MONDAY THROUGH FRIDAY/...
VFR conditions are expected throughout the week. Winds will be
shifting out of the west this afternoon. Gusts to around 20-25
knots may be possible throughout the day. Winds decrease and may
go light and variable for a time overnight, before picking up
out of the northwest again toward daybreak behind a reinforcing
cold front. These northwesterly winds should gust to around 20
knots through the day Tuesday. Lighter winds southeasterly winds
are forecast for Wednesday and Thursday as high pressure moves
offshore. Light southerly winds are expected on Friday.

&&

.MARINE...
SCAs have expired for all waters. However; there are a few
places that tend to show winds to or above 18 knots over the
open Chesapeake and parts of the Tidal Potomac. Should these
winds linger over the next hour, we may be issuing Marine
Weather Statements for this reason for late this morning and
into this afternoon. Winds will pick up out of the northwest
late tonight into the day Tuesday behind a reinforcing cold
front. Confidence is higher for SCA gusts during the day
Tuesday. Thereafter, lighter winds are expected over the waters
for Wednesday, Thursday, and Friday as high pressure builds
offshore. Winds are forecast to be out of the southeast on
Wednesday and Thursday, and then out of the south on Friday.

&&

.FIRE WEATHER...
No precipitation is expected across the forecast area through the
upcoming work week as a drier airmass works in from the northwest.
Following a wetting rainfall yesterday, the threat for dangerous
fire weather conditions appears to be low today, despite RHs
dropping into the upper 20s and 30s, with winds gusting to around 20-
25 mph out of the west.

Tuesday currently appears to be the most threatening fire weather
day of the week, with northwesterly winds gusting to around 20-25
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 upper 20s and lower 30s, 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.
