Area Forecast Discussion

326 PM EDT Fri Jul 2 2021

.SYNOPSIS...
A well-defined upper low now over NW PA will slide slowly east
tonight and hang up over eastern PA on Saturday. Numerous
showers and thunderstorms are expected again on Saturday, mainly
during the afternoon. As this upper level feature moves away,
the weather will improve on Sunday with comfortable
temperatures and humidity. Only isolated showers are possible on
the afternoon Sunday, the 4th of July.

Hot, humid weather will return for the new week, and rain is
likely during the middle of the upcoming week.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
5H low appears to be over Warren Co at 18Z, moving slightly to
the south and east. Numerous SHRA/TSRA on the radar, mainly over
the NW. The cold temps aloft are making some small hail fall
out of the taller storms. Temps are cooling off where, and near,
the showers have passed through. The lowest chc for showers for
the next few hours will be in the south-central mtns. The
highest chances will be in the PVA east of the low. The loss of
sun/heating later this aftn and evening will diminish the
showers, but some will linger through midnight due to the good
upper forcing. Overnight, the majority of the CWA will be dry
and some clearing will lead to fog forming, despite the
dewpoints only in the 50s. Mins will be close to 50F on the
highest elevations, but close to 60F in the urban areas along
and near the Susq River.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/...
After the morning fog and any low clouds burn off, SHRA/TSRA
will pop back up. The upper low will be over ern PA by then, and
we expect the majority of the convection to be to the east of
UNV. Keeping the PoPs very similar to going forecast with
liklies in the eastern quarter of the CWA tapering to low
chc/sct for the western half of the area. Maxes should be
cooler compared to Friday over the east where more clouds and
the rain will keep it in the u60s-m70s.

&&

.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
Independence Day on Sunday looks to have the best weather of the
weekend, as the main cold core upper trough shifts east of the
region. Although an isolated afternoon shower or thunderstorm
can't be ruled out, much of the day looks rain- free. And it will
be milder than Friday and Saturday but not too warm. Monday
also looks generally rain- free, as a weak warm front crosses
through and heights rise across the region. Monday will also be
significantly warmer, with temperatures rising back to the mid
and upper 80s for highs.

As more heat and humidity begins to build by Tuesday and a weak
cold front approaches from the northwest, at least isolated
afternoon showers and thunderstorms could make a return. Latest
medium range guidance suggests this front will stall out over PA
Wednesday and into late week possibly supporting a return to a
wetter pattern.

&&

.AVIATION /19Z FRIDAY THROUGH WEDNESDAY/...
Scattered showers and thunderstorms may cause local reductions
for a brief time. All shower and thunderstorm activity will
dwindle after sunset. Reductions to MVFR at most sites tonight
and into tomorrow morning. Possible brief reduction to IFR at
BFD and JST during this time.

Another round of showers and thunderstorms expected Saturday
afternoon, very similar to today. Expect brief reductions during
this time.

Conditions improve for the later part of the weekend.
