360 FXUS61 KCTP 120526 AFDCTP Area Forecast Discussion National Weather Service State College PA 1226 AM EST Wed Nov 12 2025 .SYNOPSIS... * Lake-effect and upslope snow showers continue this Veteran`s Day as blustery winds keep wind chills near or below freezing * Gusty winds in the Laurels and lake effect rain/snow showers across the northern tier will continue Wednesday and Thursday * Building high pressure into the weekend will contribute to drier conditions and a gradual warm up to near average. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... Northwest flow in the wake of a strong low that tracked across the Great Lakes will continue to bring lake effect/upslope snow showers to Central PA today. Definite lull in the heaviest, most organized bands and Lake Effect Snow Warning/Winter Weather Advisories were allowed to expire. Snow showers with a Lake Huron connection oriented NW to SE will slowly shift to a more W to E alignment today as winds turn counter clockwise thanks to the retreating low pressure center. With such cold temperatures aloft, strong snow showers/squalls will remain possible through the day and we could even see a few showers make it into southeast PA. The Snow Squall Parameter still lights up for this afternoon, so scattered to numerous squalls are still possible, despite current diminished activity at this time. As is typical in this westerly flow regime in the cold season, cloudy skies will persist along/west/north of I-99 & I-80 while downsloping east of the Allegheny Front should support some breaks in the clouds farther southeast. Air temperatures increasing to above freezing this afternoon across southeast PA will help mitigate the risk for flash freeze conditions there, but the risk will be maximized along and north of I-80. Motorists should delay travel or exit the highway when a snow squall warning is issued. Breezy northwest winds will continue into this evening, but the strongest gusts have subsided for today, so allowed the Wind Advisory to expire as well. Southwest winds and a quick upper level disturbance bringing clouds overhead tonight mean slightly milder temperatures. We`ll see precipitation continue north of I-80 with perhaps a bit more rain mixing in with snow. A coating to a half inch of additional snow is possible in the typical higher elevations west of the Allegheny Front. && .SHORT TERM /6 AM THIS MORNING THROUGH 6 PM THURSDAY/... Wednesday looks similar to Tuesday, though just a bit warmer, and less in the way of coverage of snow showers. A tight pressure gradient will allow for winds gusts in the 30 to 35 mph range Wednesday, with some guidance suggesting the potential for gusts over the Laurel Highlands to approach 40 to 45 mph. A Wind Advisory will likely be needed, though perhaps not extending as far north. Winds aloft will be more zonal, helping steer lake effect showers (rain/snow mix) mainly north of I-80 on Wednesday. Warm advection will keep temperatures trending up, with highs ranging from the middle 30s in the northern tier to low 50s in the southeast. Gusty winds will still pack a punch, but won`t feel quite as chilling when the temperatures are noticeably warmer. && .LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/... Upper-level troughing will remain in place through the end of the week, keeping the chance for rain and snow showers in the forecast each day through Thursday, especially over northwest PA. Clouds will persist in the northwest, while a mix of sun and clouds is more of the norm in the southeast. The December-like cold airmass is forecast to retreat later in the week, with temperatures returning closer to seasonal averages. High pressure looks build in from the southwest Friday into early Sunday, which should keep us mainly dry into the beginning of the weekend. Another northern stream upper shortwave traversing the Northern Plains will reach the Great Lakes early in the weekend and support a low pressure/frontal system that will move across PA Sunday into next Monday. At this point, this system appears to be not as strong or as cold as our current one, so any precip looks to be mainly in the form of rain/rain showers. && .AVIATION /06Z WEDNESDAY THROUGH SUNDAY/... Thick clouds overhead currently as bands of snow will tend to break up more and lift northward as the night goes on. The latest CAMs and upstream radar trends show the bands of snow moving across the northeastern half of the state, but snow remains light and no restrictions are expected at this time. Meanwhile, just some light, likely unrestrictive snow flurries or sprinkles could occur at MDT and LNS. Models have winds shift back to the west more by early afternoon on Wednesday, so sites like BFD may have more in the way of snow showers again. Latest guidance shows additional bands of lake effect snow moving into BFD by mid morning with restrictionsexpected through the day. Most other areas will be VFR on Wednesday. Winds will pick back up again by late morning or early aft. Outlook... Thu...Rain and snow showers over northwest PA along with gusty winds. Fri...Improvement expected, with winds diminishing and lingering -SHSN across NW PA diminishing as well. Sat...Dry, generally VFR. Sun...Increasing clouds and milder but a chance of showers, mainly late. && .CTP WATCHES/WARNINGS/ADVISORIES... None. && $$ SYNOPSIS...Banghoff NEAR TERM...Banghoff/Gartner SHORT TERM...Banghoff/Gartner LONG TERM...Banghoff/Gartner AVIATION...Bowen
