.AVIATION /14Z SATURDAY THROUGH WEDNESDAY/...
A few sprinkles could occur the remainder of this morning near
IAD, DCA, BWI and MTN as a warm front to the southwest
approaches and a line of rain showers precedes it. Otherwise, a
passing cold front could bring a few showers and perhaps a
rumble of thunder to MRB this afternoon and to IAD, DCA, BWI and
MTN later this afternoon and this evening. Some LLWS is
possible if surface winds go light or maintain a more S/SE
component into the evening as winds increase and veer aloft.
Otherwise SE to S and eventually SW winds are expected through
tonight, becoming W late. Winds will gust around 15 knots this
afternoon. By this evening, southerly gusts of 15-20 knots
become more likely, though gusts may be occasional given reduced
diurnal mixing. Once the cold front crosses, an uptick in wind
gusts is likely.
Blustery conditions are expected on both Sunday and Monday with
a relative minimum during the overnight hours. An initial wave
of gusts is possible (25-35 knots) Sunday morning in the wake of
the cold front and as diurnal mixing increases. Gusts may level
off a bit before increasing again later in the day into the
early evening as a secondary front surges through. Gusts to
around 40 knots may be possible during this time. Monday will be
breezy as well with 20-30 knot gusts likely. All of this is out
of a west to northwest direction. High pressure building in
Monday night will cause winds to become much lighter.
Sub-VFR ceilings and rain appear possible at times during the day
Tuesday. VFR conditions will return for Wednesday. Winds are
expected to be light and variable on Tuesday, and then light out of
the north on Wednesday.
