Area Forecast Discussion
National Weather Service State College PA
509 PM EDT Wed Aug 29 2018

.SYNOPSIS...
A cold front over the Great Lakes will push southeast across
Pennsylvania tonight and Thursday. The front will stall out just
south of the region Friday and Saturday, then return north as a
warm front late in the weekend. A building subtropical ridge is
expected over the Mid Atlantic region early next week.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
Another very warm and uncomfortably humid late summer afternoon
across central PA. Convection has been inhibited by warm temps
aloft and a ribbon of relatively lower pwats over the
Alleghenies keeping the day rain-free for most. Saw a lone
shower cell fire over the Lower Susq at mid afternoon before
collapsing within 30-45 minutes.

The best chance of showers/storms will come this evening across
the northwest counties as slowly approaching cold front and
prefrontal lake breeze boundary push into my northwest counties.
Sufficient mid level flow and shear noted ahead of this feature
may still support an isolated stronger storm this evening over
the northwest. In addition, a few rogue cells may reach into the
Laurel Highlands but these are increasingly encountering warmer
mid levels and will likely dissipate before reaching my area.
Heat Advisory remains in effect for our Susq Valley and Scent
Zones through this evening.

After the evening diurnal maximum, expect a broken line or two
of showers with isold tsra to be tracking through the northwest
and central mountains late tonight into the pre dawn hours
Thursday as the front slowly advances. Aside from an isolated
evening shower or storm, the east and south should remain dry
overnight.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH 6 PM THURSDAY/...
Secondary surge of cooler air will push the stalling sfc front
into my southeastern counties on Thursday morning through
midday. Although the large scale forcing is less than
impressive, diurnal heating of moist/unstable air mass is likely
to support scattered convection across the southern counties
during the late morning and afternoon. Shear is meager, so
limited threat of organized severe weather at this time.

The most pronounced cooling Thursday will be across the
northwest mountains, where model soundings suggest the day will
begin with upsloping stratus/patchy drizzle. Brightening skies
are expected by afternoon, but model blends only indicating
highs in the low 70s. Meanwhile, warm and humid conditions are
likely to persist ahead of secondary cold front with highs in
the mid to upper 80s over the Lower Susq Valley.

&&

.LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/...
The medium range guidance has the high continuing to be pushed
off shore as a shallow trough moves through and should bring
break from the heat Friday and Saturday. High pressure tracking
across New England will push frontal boundary south of the
region and result in a cooler southeast flow off the Atlantic.
Model soundings indicate there will be a fair amount of cloud
cover both days, along with the chance of showers, primarily in
the region of best orographic forcing over the south central
mountains/Laurels.

Both the 12Z NAEFS and ECENS indicate a return to very warm and
humid conditions Sunday through Tuesday, as surface high drifts
southeast off the east coast, allowing the stalled frontal
boundary to lift north as a warm front. A subtropical ridge over
the western Atlantic is progged to retrograde, taking up
residence over the Mid Atlantic coast by early next week. Under
the influence of this feature, expect above normal temperatures,
high humidity and a daily chance of PM convection.

&&

.AVIATION /21Z WEDNESDAY THROUGH MONDAY/...
Minor adjustments to the late afternoon TAFS.

About the only spot in line to see a shower or thunderstorm
early this evening is BFD.

Earlier discussion below.

Strong high pressure sfc and aloft should keep most of the area
dry through this evening. Activity this evening will organize
along or just behind the cold front over northwest PA. With
limited upper level support, thus showers and storms will most
likely weaken as they move to the east and south overnight.

Some showers and storms will be possible on Thursday, mainly
across the east and south.

.Outlook...

Fri...AM restrictions (as low as IFR or LIFR) in fog/stratus,
then VFR.

Sat...MVFR cigs with chc -shra and areas of drizzle.

Sun...Chance of showers and storms.

&&

.CTP WATCHES/WARNINGS/ADVISORIES...
Heat Advisory until 8 PM EDT this evening for PAZ028-036-046-
049>053-056>059-063>066.
