Synopsis
Low pressure will move off to the northeast of the region
overnight, with improving conditions on Friday. Warmer
temperatures and chance for showers and thunderstorms will
return over the weekend. A cold front will approach from the
west on memorial day.

Near term until 6 am Friday morning
Current analysis indicating sfc low pressure centered over
southern nj, with upper level low hanging back over
western central pa. Some scattered convection still pushing
through far NE sections of the cwa, with mainly dry conditions
elsewhere though will keep ~15% pop going through midnight with
a few spotty light showers still possible. Overnight... As drier
air continues to filter into the area and upper cold pool slides
farther off to the N ne, skies will avg partly cloudy most areas
(more clouds linger over the far n). Lows from the mid 50s W to
low 60s at the immediate coast.

Short term 6 am Friday morning through Sunday
Other than possible isold shras and vrb clouds far nne locations
early Fri as upper level low is slow to reach new england... Drying
out W deep layered wnw flow. Expecting a return of temperatures
back to or above normal W partly-mostly sunny conditions. Highs
mainly 80 to 85f... Except u70s at (most of) the beaches.

Weak ridge aloft nudges into the region from the wsw Fri night
into sat. Models in a bit better consensus W the arrival of
weak S W tracking into the fa by Sat afternoon. Combination of
daytime heating and that S W in wnw flow aloft will likely result
in at least sct convective development. Will have pops
increasing to 30-50% over most of the fa. SPC has outlooked
wrn central areas of fa slgt risk svr... Other areas marginal
svr. Otherwise... Partly cloudy Fri night- Sat morning... Then
becoming mostly cloudy Sat afternoon. Lows from the u50s NW to
the low 60s se. Highs Sat from the m-u70s- around 80f on the
eastern shore to the m-u80s inland.

Nearly zonal flow aloft remains Sat night into sun. Another S w
aloft expected to arrive during sun... Which again combined w
daytime heating likely results in sct convective development.

Lows Sat night ranging through the 60s. Partly sunny Sun w
highs mainly in the l-m80s (70s at the beaches).

Will highlight possible strong to severe tstms in hwo for the
weekend.

Long term Sunday night through Thursday
The somewhat unsettled weather will continue into Monday with the
baroclinic zone nearby and a strong upper jet just north of the
area. Expect additional showers and thunderstorms once again on
Monday in the cyclonic flow. It will be a warm day with highs in the
mid-upper 80s. The front will stall out over north carolina on
Tuesday and may allow for additional showers and storms Tuesday
across NE nc and south va. High pressure builds across the
region for Tue night-Thursday with dry and seasonable conditions
expected.

Aviation 02z Friday through Tuesday
Widespread showers and thunderstorms have mostly ended over the
cwa except for the eastern shore where it should end before
midnight. A few scattered showers still linger over portions of
central va and nc but should be ended in another hour or so.

Winds are mostly se-sw 10-15 kt and gusty. The winds will
diminish inland but will likely be 10-20 kt near the coastal
areas.VFR conditions will take hold tonight as drier weather
moves into the region.

Friday should be dry withVFR conditions, then sct showers and
storms return for Saturday into early next week as the pattern
remains somewhat unsettled.

Marine
Latest sfc analysis shows a broad area of low pres across the
mid atlc - oh valley with its main cold front already pushing
offshore. SW flow continues tonight behind the front, and still
looks to be enough of a gradient for 15-20 kt winds over most
waters... So headlines over the bay sound lwr james extend
through at least Fri morning. The SCA over the ocean is for seas
up to 5 ft out 20 nm. Weak high pres then builds in for late
fri Fri night leading to improving marine conditions. Sub-sca
conditions expected to continue into the weekend.

Tides coastal flooding
Previous onshore flow combined with high astro tides will
result in elevated water levels through Friday. Have issued
several coastal flood products to account for this. See cfwakq
for more details.
