Synopsis
A cold front will approach from the west and move through the region
tonight into early Saturday. High pressure returns for Sunday
through Tuesday. Another cold front will cross the region on
Wednesday followed by high pressure for the end of the week.

Near term through tonight
Showers and thunderstorms over eastern nj will move offshore
this morning. These showers storms are producing locally heavy
rain, but are moving fairly quickly, helping to mitigate any
flooding. Additional showers and thunderstorms can develop
pretty much at any time today, but most of the area should
remain dry from late morning through early afternoon.

Will need breaks in the clouds during this time, which will
help destabilize the atmosphere this afternoon. Owing to strong
heating and anomalously high moisture content in the boundary
layer (surface dewpoints well into the 70s), forecast models
indicate a moderately unstable environment (sbcape of 2000-3000
j kg) to sustain strong convective updrafts this afternoon.

Storms are expected to initiate just ahead of the cold front
across the higher terrain in central and northeastern pa during
the mid afternoon. These storms are then expected to move
eastward into eastern pa late this afternoon and the i-95
corridor this evening. Convection may linger into the overnight
near the coast. Cams have come into much better agreement with
the above-mentioned timing of storms.

A flash flood watch remains in effect for most of the CWA for
this afternoon and evening. The watch does not include the
southern poconos (higher ffg) and southeastern nj into southern
de (higher FFG and greater uncertainty if storms maintain
intensity to produce excessive rainfall rates by the time they
move into our far southeastern zones late this evening or
overnight). Pwats are forecast to increase to between 2.25-2.5,
which is +2 to +3sd above climo for this time of year. While
storm motion should be fast enough to preclude widespread heavy
rainfall, upstream corfidi vectors show a potential for
convective training that could lead to locally heavy rainfall
totals. With nwp support from cams, there is a potential for
isolated rainfall amounts of 3-6 inches. The flash flood threat
may peak after sunset this evening as convection (and associated
cold pools) starts to weaken with the loss of heating. Storm
motion may subsequently decrease with high rainfall rates (2+
inches per hour) still occurring.

Spc has included most of the forecast area in a slight risk for
severe thunderstorms for this afternoon and evening. Have added
damaging winds to the weather grids with that being the primary
severe thunderstorm threat. However, isolated large hail and
even a tornado is possible this afternoon and evening.

Today will feel very muggy with dewpoints rising into the mid 70s
and even near 80f across DELMARVA and far southern nj. Heat indices
are expected to peak into the mid 90s across the urban i-95 corridor
and near 100f in delmarva. Held off on a heat advisory but heat
indices will only be a few degrees below issuance criteria. Humid
conditions continue into tonight, especially along and east of i-95,
where forecast lows are in the mid 70s.

Short term Saturday
The cold front should be offshore by Saturday morning with all
precipitation having come to an end. As the upper trough pushes
through later Saturday, we should really start to see the dry air
filter into the area. Saturday will be a fairly nice day with the
sun shining across the region. Models are showing a slug of moisture
crossing the region as the upper trough moves through. However, it
appears to weaken as it moves over the mountains to our west and
peters out before reaching our area. We will continue to keep the
forecast mostly dry at this time, although an isolated shower or
thunderstorm can not be ruled out later in the day Saturday. Best
chance for anything to reach the ground looks to be across the
northwestern zones so have included a slight chance for showers
later Saturday.

Long term Saturday night through Thursday
High pressure will build in for Sunday and a period of relatively
nice weather should continue for the start of the week with the high
shifting offshore on Monday. Another cold front will approach the
region from the west on Tuesday, crossing the area on Wednesday.

Models continue to show a surface trough developing on Tuesday in
advance of the cold front. This trough, combined with a shortwave
moving through the mid levels, will spark off some convection on
Tuesday. Additional showers and thunderstorms will be accompany the
cold front on Wednesday, with the storms ending from west to east on
Wednesday evening. A few showers may linger early Thursday, mainly
along the coast. High pressure, accompanied by some cooler air, will
build down from canada and across our area for the end of the
week.

Aviation 14z Friday through Tuesday
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.

Widespread ifr MVFR CIGS across the terminals this morning
should gradually scatter out and give way toVFR conditions.

Bulk of shra tsra currently away from terminals, and although
showers can develop at any time this morning, the bulk of the
activity will hold off until late afternoon.

Showers and storms are expected to redevelop after 18z this
afternoon mainly in vicinity of western terminals (abe-rdg),
then move eastward through the i-95 terminals this evening
(between 23-03z) and eventually our eastern terminals (miv-acy)
late in the evening. A period of ifr restrictions are likely
when these storms move through.

Winds will predominately be out of the south today and tonight.

Speeds will generally be 10 kt or less. However, they could increase
to above 10 kt for a period this afternoon with occasional gusts up
to 20 kt possible. Much stronger winds are possible with storms.

Outlook...

Saturday... Fog possible early. Otherwise, mainlyVFR conditions
expected. Northwest to west winds around 10 to 15 knots.

Sunday... MainlyVFR conditions expected. Westerly winds around 10
knots or less.

Monday and Tuesday... MainlyVFR conditions expected. Southerly winds
around 10 knots or less.

Marine
A SCA was issued for the coastal atlantic waters and delaware bay
from late this morning through this evening. Despite less than ideal
mixing profiles in southerly flow (warm air above the relatively
cooler waters), 25 kt winds are only 200-300 ft off the deck. Deeper
mixing on land could easily transport these higher winds down to the
surface in our nearshore waters. Seas in the coastal waters are
forecast to increase to around 5 ft late this afternoon and evening.

Strong thunderstorms mainly this evening could contain locally gusty
winds, requiring special marine warnings.

Outlook...

Saturday through Tuesday... Sub-small craft advisory conditions
expected on the area waters through Tuesday.

Rip currents...

a moderate risk for the development of dangerous rip currents is
forecast for today for de and nj shore, given increasing southerly
winds and seas.
