.DISCUSSION...
KEY MESSAGE 1...Freeze Watch is in effect for much of central and
northeast MD, eastern WV Panhandle, and much of central,
northern, and northeast VA Tuesday night into early Wednesday.
A low pressure system will move across the eastern Great Lakes
tonight and Tuesday morning, then into and across New England
Tuesday afternoon. An associated cold front will drag across the
region later tonight and early Tuesday morning. While little to
no precipitation is expected with this front, the main concern
will be the cold air pushing into the region from the northwest
late Tuesday into midday Wednesday. High pressure will build
behind the front in support of this cold air. While conditions
may be breezy with gusts over 25 mph Tuesday, the winds are
expected to diminish late and into Tuesday night. This will
allow for our temperatures to drop more quickly and into the
freezing or sub- freezing realm of possibility over such a large
area. A Freeze Watch has been issued for a large area from the
Shenandoah Valley to the I-95 corridor, excluding the Blue Ridge
Mountains. Temperatures Tuesday night could drop to 25 to 31
degrees in the areas of the Freeze Watch. Please monitor your
sensitive vegetation, gardens, flowers, plants, etc and perhaps
bring them inside or insolate them. Wednesday night could be
cold as well. We will monitor temperatures for this period to
decide if further watches or advisories are needed.
KEY MESSAGE 2...Dry conditions through the week. Cool temperatures
through midweek, then a warming trend expected late week.
A weak disturbance will move quickly to the north of our region
tonight. Other than a sprinkle or two in the Alleghenies, areas
should be dry. Temperatures reached near average for early April
this afternoon and much of the same tonight. Colder temperatures
on the way Tuesday and Wednesday with the next storm system and
cold front. Highs in the lower to mid 50s and lows in the lower
to mid 30s each day and night. Dry conditions anticipated
through the period. As a matter of fact, dry conditions are
anticipated through the rest of the week with temperatures
modifying to above average by the end of the week. Highs in the
60s on Thursday, the 70s on Friday and perhaps hitting 80
degrees for most places by the weekend.
&&
.AVIATION /18Z MONDAY THROUGH SATURDAY/...
VFR conditions are expected through the week. Winds light and
variable tonight, then increasing mid-morning and Tuesday
afternoon. Winds will become northwesterly and gust to around
20 knots Tuesday. Lighter winds southeasterly winds are
forecast for Wednesday and Thursday as high pressure moves
offshore. Light southerly winds are expected on Friday.
&&
.MARINE...
Special Marine Statements are in effect until 4pm for Upper
Tidal Potomac and Northern Bay. Winds will pick up again out
of the northwest late tonight into the day Tuesday behind a
reinforcing cold front. A Small Craft Advisory is in effect for
all waters Tuesday from 8am to 8pm. 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.
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.
