Area Forecast Discussion National Weather Service State College PA 317 AM EDT Fri Aug 14 2020

SYNOPSIS. A stationary frontal zone wavering over southern PA will maintain a chance of scattered, locally heavy downpours later today. Unsettled conditions with cooler temperatures are forecast for the upcoming weekend.

NEAR TERM /UNTIL 8 AM THIS MORNING/. Will maintain just a slight chance of a shower early this morning across the southeast part of the forecast area, where high pwat air mass and lingering instability remain per 06Z SPC mesoanalysis. Elsewhere, have dropped POPS to zero early this morning across the northern half of the state, where much drier air resides.

A light easterly flow, combined with radiative cooling, appears likely to result in increasing stratus and patchy fog early this morning across the southern half of the state. Much drier air north of stalled frontal boundary should result in mostly clear skies across northern Pa, but can't rule out a bit of fog in the deep valleys along the NY border, due to falling temperatures and warm river/stream waters.

Temperatures are on track to bottom out from the upper 50s in the valleys of northern Pa, to around 70F over the Lower Susq Valley, where cloud cover and high humidity will limit radiational cooling.

SHORT TERM /8 AM THIS MORNING THROUGH 6 AM SATURDAY/. Model soundings indicate any morning low clouds/fog should give way to partly sunny skies later today. Expect scattered, diurnally-driven convection to form during the afternoon over the southern half of the state, in moderately unstable air mass along and south of remnant frontal boundary. Have placed the highest POPs of around 50pct along the Mason Dixon Line, where pwats are highest. Weak winds aloft and 0-6km shear only around 15kts indicate any storms will be of the pulse variety with little risk of severe weather.

Dry ground and a decent amount of sunshine should result in another warm day relative to climatology across the northern half of the state, with highs in the upper 80s possible in the valleys along I-80. More cloud cover and scattered convection should hold readings close to average across the southern counties.

Any showers/storms across southern Pa should die with loss of heating this evening, then expect dry weather the rest of the night. An approaching upper trough and surface low over the Ohio Valley will spread increasing clouds into the region overnight, with an outside chance of a shower reaching Somerset County by dawn.

LONG TERM /SATURDAY THROUGH THURSDAY/. Split flow produces a weak broad upper trough over the lingering frontal boundary to our south. This will bring a surge of moisture into the Commonwealth Saturday afternoon and Sunday. Anomalous southeasterly 850-mb flow (approaching record values for this time of year) will help funnel ample moisture into the Middle Atlantic. Have upped PoPs in the SW starting Saturday afternoon and maintain higher PoPs farther east through Sunday evening. Despite the GFS being the outlier earlier in the week, other models have gradually trended toward a wetter solution. Still, ample uncertainty remains. The NAM brings almost no rain to north of the Mason-Dixon line Saturday and Sunday, while the GEFS mean sits at widespread storm total precip exceeding 1" and spotty 2" amounts across south central PA. Opted to ramp up PoPs across south-central PA where confidence is highest in rain occurring, but shaved off about 20% of QPF from a blend of NBM, WPC Guidance, and the SuperBlend.

The weak surface trough will stick around through Monday before a cold front sweeps through the Commonwealth, marking the end of an unsettled stretch and ushering in cooler and drier weather.

The Climate Prediction Center 6-10 temperature outlook favors below normal temperatures in central PA. This will be a welcome relief after a prolonged stretch of warm weather. Additionally, the arrival of high pressure by the middle of next week seems to favor a drier than normal stretch for a little bit.

Precipitation chances ramp up again across the southern tier by late week, but no significant impacts are expected.

AVIATION /07Z FRIDAY THROUGH TUESDAY/. Very minor adjustments made at 1125 PM.

New data coming in supports a mainly dry day on Friday.

Earlier discussion below.

00Z TAFS sent.

Isolated showers and storms across the south, but not near any TAF sites at this point.

Some fog and lower clouds possible late, but rainfall less widespread today than in recent days, thus I did not hit fog and low clouds very hard.

Friday at this point looks mainly dry, similar to what we had today, thus only used VCSH across the south.

More in the way of widespread showers possible for later Saturday into Sunday Night, but still a ways out. Much of our area could remain between systems to the southeast and southwest of our area.

Outlook .

Sat-Sun . More in the way of widespread showers possible. Mon . Still a chance of showers and storms. Tue . Clearing skies.

CLIMATE. A daily record high temperature of 87 degrees was tied at Bradford on 8/13. The previous record was set in 1988.

CTP WATCHES/WARNINGS/ADVISORIES. None.
