.DISCUSSION...
KEY MESSAGE 1...Freeze Warnings remain in effect for the
majority of the area early this morning. Freeze Watches remain
in effect for many locations tonight.
High pressure continues to build to our north across Upstate NY
early this morning. Winds remain light out of the northeast in
many locations, but temperatures have dropped back into the
upper 20s and 30s across the region. Freeze Warnings are in
effect through 9 AM for all zones where the growing season is
ongoing, except for Calvert and St. Mary`s County.
Sunny skies are forecast for all today, with temperatures
climbing into the 50s. Winds will start out northeasterly, but
turn more southeasterly over the course of the day. High
pressure will build over Southern New England this evening, and
then offshore later tonight. A surface ridge will extend
southwestward from the high, encompassing much of the Mid-
Atlantic. A weaker pressure gradient should allow for more
locations to ultimately decouple tonight, but the ambient
airmass will be a bit warmer and the dewpoints will be a bit
higher. With clear skies and light to calm winds, it will be an
ideal setup for radiational cooling tonight. Many locations will
once again drop to near or slightly below freezing. Freeze
Watches remain in effect for tonight for most of the forecast
area where the growing season is ongoing (the exception being
the inner DC/Baltimore Metros and southern Maryland). The Freeze
Watches will eventually need to be upgraded to Freeze Warnings
and Frost Advisories. Final decisions on Freeze Warnings and
Frost Advisories for tonight will likely be made later this
morning after the current Freeze Warning is allowed to expire.
As high pressure progresses offshore, winds will become
southeasterly on Thursday, and then southerly on Friday. The
southerly component to the wind will draw warmer air northward
into the area, resulting in a warming trend in temperatures.
Highs are forecast to reach into the 60s on Thursday, and then
70s on Friday.
KEY MESSAGE 2...Dry frontal passage Saturday with continued
moderating trend in temps.
High pressure ushers in above normal temps for Fri. Low pressure
scoots well north of the area Fri night, with a trailing cold front
progged to cross the local area Sat. Not expecting much if any
precip with this FROPA as the moisture appears rather limited.
Greatest (albeit low) probs for a rain shower are along the
Allegheny Front. Temps will be a few degrees lower Sat and Sun
because of this, but remain above normal.
Sfc high pressure will move east through the early portions of next
week with ridging aloft building in. Temps will continue to increase
to well above avg values. Can challenge some record highs Tue and
Wed with mid to upper 80s possible.
&&
.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
VFR conditions are expected at the terminals over the next
several days. Winds will be out of the northeast this morning,
before eventually turning out of the southeast this afternoon.
Winds potentially go light and variable or calm for a brief time
overnight tonight, before southeasterly flow resumes during the
day Thursday. Southerly winds are expected on Friday.
VFR conditions are forecast for Saturday into Sunday. Light
northwesterly winds Saturday become light out of the south on
Sunday.
&&
.MARINE...
SCAs continue within northeasterly flow early this morning.
Winds should gradually subside shortly after daybreak, reaching
sub-SCA levels by mid-morning. Thereafter, winds should remain
sub-SCA in magnitude over the next few days. Winds will be out
of the east this afternoon, southeast tonight into Thursday, and
then out of the south on Friday.
Sub-SCA level winds are expected this weekend. Winds will
generally be out of the northwest on Saturday, and then south on
Sunday.
