Synopsis
A boundary will remain nearly stationary across the region
through Wednesday. Low pressure will move through the ohio
valley on Thursday and drag a cold front through the mid-
atlantic states Thursday night. High pressure will build in for
Friday and through much of the weekend. A warm front will push
northward through the area late Sunday into Monday, followed by
a cold front later Monday. High pressure will return once again
as we head into the middle of the week.

Near term until 6 am Wednesday morning
A severe thunderstorm watch remains in effect for much of our
area until 10:00 pm this evening.

A flash flood watch remains in effect for our entire area until
6:00 am Wednesday.

The initial area of showers and thunderstorms near and to the
north of the slow moving surface front continued to affect
parts of southeastern pennsylvania into central and northern
new jersey around 6:00 pm. The precipitation will move slowly to
the east this evening. Locally heavy rain and isolated severe
weather remain possible with those showers and thunderstorms.

Meanwhile, additional showers and thunderstorms that were
developing in northeastern virginia and vicinity will move to
the east and northeast. They should impact northeastern
maryland, delaware and southern new jersey this evening and into
the overnight hours, bringing locally heavy rain and the threat
for damaging winds and hail.

Low temperatures tonight will favor the lower and middle 60s in
the north, and the upper 60s and lower 70s elsewhere. The wind
is anticipated to become light and variable.

Short term 6 am Wednesday morning through 6 pm Wednesday
Cloudy and damp conditions will start the day again Wednesday
as a frontal boundary will remains near the area. The morning
should be mostly dry, however, as the day progresses, clouds
will begin to dissipate and instability will build across the
area. With the front in place, the building instability, and
passing short waves vorticity impulses, showers and
thunderstorms are likely to redevelop by the late morning and
especially during the afternoon. Pw values remain very juicy
around 1.75-2.00 inches, so there remains the threat for heavy
rainfall. We did not extend the flash flood watch into Wednesday
as there is uncertainty as to where the heaviest rain will
occur, especially in relation to the heavy rain from today.

Later shifts can take another look and see if and where the need
for an extension could be needed.

Long term Wednesday night through Tuesday
The extended starts off active and then hopefully we can catch
a decent break between systems as we head through the weekend.

More unsettled weather to start the new week and then another
brief respite from the rain for the region through midweek.

Where to begin... It's been a very active spring around the
middle atlantic and that pattern looks to continue as we head
through the rest of this week. The stalled boundary remains
across the forecast area as we head into Wednesday night through
Thursday (although it really starts to look like it has
weakened and is washing out for the most part) so we can expect
more showers and thunderstorms across the region.

A low pressure system will track through the ohio valley and
into the mid-atlantic with the attendant cold front moving
through Thursday night. Good surface heating on Thursday will
help with convective initiation as we remain in the warm sector.

A shortwave rolling through the region will help to provide
additional lift and the continued southerly flow we have will
also add plenty of moisture so expect a fairly active day for
our area on Thursday. With pwats running high for this time of
year (>1.5 inches) so expect any storms that develop to be very
efficient rainmakers.

Things should clear out behind the departing front on Friday
with maybe some lingering showers early in the morning.

Otherwise, Friday will become windy in the northwest flow but it
should feel refreshing with cooler temps and relatively dry
conditions.

The quiet weather will continue through Saturday and most of
Sunday. Overall a nice weekend is in store for the weekend with
highs into the 80s across much of the forecast area.

The next system arrives Sunday night as a warm front moves
northward through the region, followed by a cold front on
Monday. Showers and thunderstorms will remain possible through
this period. High pressure will then try to build in behind the
front and persist through midweek.

Aviation 22z Tuesday through Sunday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Tonight... Outside of showers and thunderstorms, conditions will
beVFR. Showers and thunderstorms will end for abe and rdg
this evening. However, the other TAF sites will likely keep
showers and possibly thunderstorms into tonight, especially acy
and miv.

All sites will lower back to MVFR then ifr overnight tonight as
low clouds and areas of fog spread across the area. Winds will
be variable from site to site due to the frontal boundary near
the area and approaching low pressure system.

Wednesday... Conditions will start out MVFR and or ifr during
the morning, before improving toVFR by late morning into the
afternoon. However, showers and possibly thunderstorms will
develop later in the morning and into the afternoon which could
temporarily lead to lower conditions. Wind are expected to vary
from southeast to southwest around 5-10 knots.

Outlook...

Wednesday night... GenerallyVFR conditions expected but MVFR or
lower is possible in low clouds and rain. Light southerly
winds. Low confidence.

Thursday through Thursday night... Periods ofVFR outside of
showers and thunderstorms, where MVFR or lower conditions will
be possible. Showers and thunderstorms are likely during the
afternoon and evening. South to southwest winds around 10 knots
veering to the west overnight. Low confidence on timing and
severity of storms.

Friday through Friday night... MVFR possible early with
improvement toVFR by around midday. Northwest winds around 10
to 15 knots with gusts up to 25 knots possible. Moderate
confidence.

Saturday through Sunday... MainlyVFR conditions expected.

Northwest winds around 5 to 10 knots, becoming light overnight.

Moderate confidence.

Marine
Tonight... Conditions remain below small craft advisory levels
through tonight. There will be a chance of thunderstorms through
this evening which could lead to locally higher winds and
waves.

Wednesday... Conditions remain below small craft advisory levels
through Wednesday. There will be a chance of thunderstorms
during the afternoon which could lead to locally higher winds
and waves.

Outlook...

Wednesday night through Thursday... Sub-advisory conditions
expected. Winds out of the south to southeast around 10 to 15
knots. Seas around 2 to 4 feet.

Thursday night through Friday... Winds will increase out of the
northwest at 10 to 20 knots with gusts up to 30 knots possible.

Seas will also build to around 4 to 6 feet. A small craft
advisory will likely be needed.

Friday night through Sunday... Small craft advisory conditions
may linger into Friday night but are expected to fall below
criteria and then remain down through the period. West to
northwest winds around 10 to 15 knots Friday night into
Saturday, becoming around 10 knots on Saturday. Winds will
become light on Sunday before favoring the south by Sunday night
through Monday. Seas will be around 1 to 3 feet through the
period.

Rip currents...

a low risk for the development of dangerous rip currents is
expected to continue through today with waves in the surf zone 3
feet or less.
