Synopsis
A ridge of high pressure will drift off the mid atlantic coast
this evening. Low pressure lifting northeast across the great
lakes on Thursday will drag a strong cold front across
pennsylvania late Thursday. Cooler and dry weather will prevail
on Friday. The holiday weekend will bring warmer temperatures,
higher humidity and a renewed chance for showers and storms at
times.

Near term until 6 am Thursday morning
Mid and high clouds are bleeding over the top of the big
eastern upper ridge. As the surface high moves off to our east,
bringing the low level flow around to the se, eventually gusting
10-15 mph.

The hrrr is consistent in bringing the chance of showers back
into my nwrn zones between about 4-6pm. Radar and observations
do show some light showers moving out of oh with rain at eri as
of 2pm. While most of the region will remain dry, we did
include a 20-30% pop from mid afternoon into the evening.

The prospects for the overnight a tad less certain. There is a
good chance a dying area of showers will work across, but
looking at the various flavors of the href lends little
confidence about how big an area actually sees rain by morning.

I used blended pops that tracked the best chance of rain from nw
pa down over central pa into my sern zones by sunrise.

With clouds and showers, lows will only drop back into the 50s.

Short term 6 am Thursday morning through 6 pm Thursday
Morning showers will quickly move east of the area by late
morning and early aft.

The warm front, lee trough will be across the far east on
Thursday, as a cold front moves into western areas toward
late aft.

While temperatures and dewpoints will be borderline for
severe weather, the combination of shear and timing of
the system near MAX heating will result in the risk of
some strong to severe storms. Wind fields best across the
north, while the better heating and dewpoints are expected
across the south.

Storms that form will move quickely to the southeast, a
typical NW flow event. SPC day 2 outlk has an enhanced risk for
much of our cwa.

More information below.

This is a classic supercell and potential large hail-producing
environment as storm relative inflow updraft helicity will be
unusually high INVOF sfc warm front lee trough across ncent pa
and the susq valley during the afternoon hours. Low lcls under
3000 ft agl covering much of central and eastern pa and strong
llvl shear will lead to 0-1km ehis of 2-4(m^2 sec^2) near the
warm front lee trough over the central and eastern zones between
21z Thu and 00z fri. The threat of several tornado-producing
supercells will occur across this same region from mid afternoon
to around dusk.

In addition to the anticipated hail and isolated tornado threat,
the supercells and their strong updrafts will have the potential
for damaging winds, given the storm speed and winds aloft.

Long term Thursday night through Wednesday
Weighted the fcst to what we had at first with minor
adjustments to grids, then went across the grids again after
looking at the 12z ec.

Main changes then was to up the pops Saturday night into Sunday.

I did lower pops some more for Monday into tue. Wed is a mix of
the superblend and some minor adjustments.

Flow pattern remains abnormally fast and active.

Temperatures for the most part will be warmer than normal, but
not that abnormal for the first big holiday weekend of the warm
season.

Aviation 19z Wednesday through Monday
A ridge of high pressure today will slide off the mid atlantic
coast this evening.

WidespreadVFR can be expected today and much of tonight, with
scattered restrictions possible with a dying area of showers and
thunderstorms that will traverse the area during the evening and
overnight.

Winds starting off light and variable will become s-se 5-10 kt,
eventually gusting into the teens.

Enhanced weather impacts expected on Thursday from mid-
afternoon through the evening hours as strong to severe
thunderstorms impact the region.

Outlook
Thu...VFR into the afternoon, then strong thunderstorms
developing mid-afternoon lasting into Thu night.

Fri... Ceiling restrictions poss NW early, then mainlyVFR.

Sat... Restrictions in vicinity of showers thunderstorms. Tstms
more numerous north, scattered south.

Sun... Restrictions possible near scattered tstms, mainly west.

Monday... Still a chance of showers and storms.

Ctp watches warnings advisories
None.
