Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
938 PM EDT Wed Oct 10 2018

.SYNOPSIS...
A cold front will cross the area late Thursday
night. Hurricane Michael is expected to pass southeast of the
area early Friday morning. An upper-level disturbance will pass
through Friday night into early Saturday followed by high
pressure for the rest of the weekend.

&&

.NEAR TERM /UNTIL 7 AM THURSDAY MORNING/...
Moisture continues to surge northeastward this evening ahead of
Hurricane Michael and an approaching cold front. Shower
coverage will continue to increase overnight and may be heavy at
times. An isolated thunderstorm or two is also possible given
some elevated instability. In addition, with abundant low level
moisture, it will be another night of low stratus.

Lows tonight in the 60s to low 70s.

&&

.SHORT TERM /7 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/...
Cold front approaching from the west will be interacting with
moisture associated with what is expected to be Tropical Storm
Michael. Widespread showers, some of them moderate to heavy,
are expected all day Thu into Thu evening with total rainfall
amounts of 1 to 3 inches across central VA and south/east of
I-95, with heaviest over southern Maryland and portions of
central VA where localized amounts of up to 4 inches are
possible. Less than one inch is expected NW of the metro areas
toward western MD. A Flash Flood Watch is in effect where the
heaviest amounts are expected. Rain will begin to end from NW to
SE Thu evening and should be out of the area Fri morning. Gusty
NW winds will occur behind front late Thu night with 6-hr
period of gusts of 35-45 mph. It's possible a small window
occurs late Thursday night and early Friday morning where some
gusts near 50 mph occur in southern Maryland, and will need to
be monitored for a possible Wind Advisory.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
Upper level flow forecast to be zonal through the extended forecast
period. Thus, looking for several weaker, transitory systems over
the time frame.

Shortwave energy will be ejecting on Saturday; any precipitation
chances will come during the morning/midday hours. High pressure
will follow Saturday night into Sunday morning.  Return flow/warm
advection ensuing by afternoon with precipitation possible by night
fall. However, not all guidance sets in synch with the precipitation
layout; thus, PoPs will be low. The attendant cold front would be
through sometime on Monday...again with timing differences between
GFS/ECMWF. Such a sequence suggests that Tuesday would be a day of
high pressure, but with another shortwave/jet max lurking across the
Great Lakes and recognizing timing variabilities of such a pattern,
confidence slightly on the lower side.

Temperatures likely to be on the cooler side. The warmest day, with
near normal temperatures, will come on Monday before cold frontal
passage.

.AVIATION /02Z THURSDAY THROUGH MONDAY/...
Cigs becoming MVFR/IFR late tonight with frequent showers. MVFR
cigs with showers persist through Thu evening. Abrupt wind

the north/northwest. A Gale Warning has been issued for late
Thursday night into Friday for wind gusts 35-45 knots. It's
possible some gusts may approach 50 knots over the open waters
of the central Chesapeake Bay, and further consideration for a
Storm Warning may be warranted. Otherwise, SCA conditions are
likely to persist through Saturday.
