Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
400 AM EDT Sun Aug 13 2017


The cold front which pushed through the area will become
stationary across the Carolinas early in the week. Weak high
pressure builds over the area Sunday and holds through mid
week. A weak frontal boundary will move into the Mid Atlantic
late in the week.



As of 3am, the cold front has cleared the CWA with sprinkles
lingering from southern Nelson to the Point Lookout. A broad west to
east jet streak extends from NY state to central VA. The southern
half, south of the Mason-Dixon line features high clouds streaming
overhead. The jet streak shifts offshore through the morning, so the
back edge of the clouds (currently over KY) looks to linger through
midday. Heavier MAV in temperature blend given it`s prowess in
recent days. High pressure shifts east from Chicago to Lake Erie
today. North flow mixes down 14C 850mb temps for mid 80s highs today.



High pressure center shifts east across the NY/PA border tonight
through Monday. However, the stationary front remains south of the
area through at least Tuesday. Onshore flow Monday allows chance
PoPs for the eastern slopes of the Blue Ridge in central VA. Min
temps mid 60s and max temps mid 80s through Tuesday.



High pressure over the region Wednesday. Area will see plenty of
sunshine with highs in the upper 80s.

Low pressure is expected to slide across the eastern Great Lakes
into New England Thursday. An attendant frontal boundary will
drop into the Mid Atlantic bringing increased cloud cover with
the chance of showers/thunderstorms. Clouds should diminish as
the weekend approaches.

Temperatures should be around climatological norms for mid



Tranquil/VFR as high pressure shifts east across the northern Mid-
Atlantic through Monday night.

VFR conditions expected Wednesday and Thursday.



NW flow behind a cold front generally 15 knots rest of the
overnight...easing to 10 knots after sunrise. High pressure builds
north of the area through Monday with flow shifting onshore.

Winds expected to remain below SCA values Wednesday/Thursday.
