Area Forecast Discussion National Weather Service State College PA 715 AM EDT Thu Apr 22 2021

SYNOPSIS. A late April cold snap will bring subfreezing temperatures and gusty winds early today and again early Friday morning. Low pressure will track south of the state, bringing a widespread and chilly light to moderate rainfall Saturday night and early Sunday. Conditions will trend warmer and drier early next week. Temperatures could touch 80 degrees by the middle of the week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. A weak mid level short wave embedded in the larger scale NW flow across the NE U.S. will track across SW PA early today, with another dropping SSE from NY state for later this morning and this afternoon.

The initial disturbance will be accompanied by more focused llvl convergence and orographic lift of the upstream Glake moisture with temps in the upper half of the approx 8 kft thick of the cloud bearing layer within the favorable DGZ.

We've seen some persistent albeit narrow moderate to heavy bands of snow drifting over the same region of the Laurel Highlands over the past several hours with vsbys generally in the 1/2 to 1 1/2SM range, though as confirmed by the most recent KJST ASOS Ob, the highest reflectivities of 25-30 dBZ were supporting 1/4SM vsbys. We've issued a few Special Weather Statements to highlight the late season snow impact to travel across several of our SW CWA zones.

Painted in 1-2 inches of snow within about 15 miles of KJST this morning, with lesser amounts as the bands weaken a bit further to the east-southeast in the Scent Ridge and valley Region. Elsewhere expect areas of a coating to perhaps one inch of snow during the mid to late morning hours as the second short wave drifts in from NY.

For the rest of the region and this afternoon, we'll see plenty of clouds and scattered flurries turning to sprinkles throughout the valleys.

Deep mixing up to 6-8 kft agl this afternoon per the latest RAP Bufkit soundings taps winds of 30 to 35 kts, which should reach the sfc as gusts of 25-30 kts in most locations.

Temperatures were in the mid 20s to lower 30s from the north to south across the state as of 08Z, except for the larger cities in the SE where readings were still between 33 and 37F.

A freeze warning remains up for parts of south central PA, where the growing season is underway. No frost is expected due to persistent/gusty winds.

Max temps this afternoon will be -15F to -20F below average (40-50F). The gusty winds will add to the chill with wind chills running about 10F lower than air temps.

Another cold night expected tonight with some risk for a freeze; frost again looks unlikely given gradient wind flow with HP centered to the south of CPA.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/. Not a lot of change. Looking at mainly dry conditions tonight into Saturday, with a moderating trend.

Still looking at some rain late Saturday into early Sunday associated with surface low tracking south of Pa. Timing similar to the last few days.

LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/. Not much spread among medium range guidance, all of which indicate anomalous upper level ridging building over the eastern conus. Thus, confidence is high for dry weather and rising temperatures.

Any rain Sunday morning should taper off fairly quickly, as surface low passes off the Mid Atlantic coast. A decent pressure gradient in its wake should result in a breezy Sunday with temperatures close to seasonal. Surface high should build over the state Monday with light wind and near average temperatures.

Much warmer air should arrive by Tuesday, as the high passes off of the coast and a return southwest flow ensues. ECENS 850 temps surge to 12-14C by Wednesday, which should translate to highs in the upper 70s and low 80s.

Latest guidance indicates upstream upper trough and associated cold front will remain well west of the area through mid week, but based on NBM have included just a slight chance of showers over the western counties late Wednesday.

AVIATION /11Z THURSDAY THROUGH MONDAY/. At 11z, upsloping NW flow continues to produce borderline MVFR/IFR cigs and vsbys over the Laurel Highlands /JST/ in occasional snow showers. MVFR cigs and vsbsys are also possible this morning at AOO and UNV, with scattered snow showers nearby. Elsewhere, VFR conds will persist.

All sites will gradually become VFR today, with JST likely taking the longest to see improvement. Wind will be gusty /20-30kts/ from 280-320 degrees through this afternoon.

Outlook .

Fri . VFR. Winds subside.

Sat . VFR early, with late-day restrictions likely in developing rain.

Sun . Showers/reduced cigs early; trending drier Sunday night. Gusty winds.

Mon . Becoming VFR, with gusty winds subsiding.

CTP WATCHES/WARNINGS/ADVISORIES. Freeze Warning until 9 AM EDT this morning for PAZ026>028-035- 036-049>052-056-057-059-063>066.
