450 FXUS61 KCTP 140416 AFDCTP Area Forecast Discussion National Weather Service State College PA 1116 PM EST Thu Nov 13 2025 .SYNOPSIS... * Mainly clear, cooler, and not as windy tonight; slightly milder and dry end to the week on Friday * Clouds increase with periods of rain Saturday afternoon into Saturday night; a gusty thunderstorm is possible * Windy and colder with lake effect snow showers Sunday into Monday && .NEAR TERM /THROUGH FRIDAY/... A few clouds linger across the CWA this evening into tonight on the southwestern periphery of a departing upper level trough. Otherwise look for mainly clear skies and decreasing wind as high pressure ridge settles into southwest PA by 12Z Friday. Fcst minimum temps are pretty close to seasonal climo in the 25-35F range, which is 5 to 15 degrees cooler than last night. && .SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY NIGHT/... A bit milder, dry and not as windy end to the week on Friday. Max/min temps remain close to the historical average for mid November in the 40-55F/25-35F range. Model guidance appears to be signaling more cloud cover/less sunshine during the day. Warm advection pattern picks up Friday night through Saturday downstream of amplifying large-scale upper trough tracking southeast from the Canadian Prairies across the Great Lakes towards the Northeast through Saturday night. Deepening sfc low moving from the U.P. of MI up the St. Lawrence River Valley will drag a trailing warm/cold frontal system through CPA Saturday afternoon through Saturday night accompanied by periods of rain. A favorable zone for a few t-storms (warm sector) capable of locally strong/severe wind gusts may exist from the Upper Ohio Valley into the western slopes of the Allegheny Mtns late Saturday afternoon into Saturday evening -- before convection weakens while crossing the higher terrain through central and eastern PA Saturday night. SPC trimmed back the MRGL SWO primarily to the west of the PBZ/CTP border, but will allow the night shift to adjust HWO with tomorrow`s Day 2 SWO. && .LONG TERM /SUNDAY THROUGH THURSDAY/... Sunday into Monday period looks quite windy and colder with brisk and blustery NW flow. Max gusts via NBM are currently in the 30-40 mph range and could see a wind advisory being needed in the coming days. The typical cold season post-frontal pattern transition will be punctuated by a ramp up of lake effect snow showers with potential for snow accumulation in the favored snowbelts, ridgetops and summits along the Allegheny Plateau. Models show the next system for early next week ejecting out of the central Plains (NE/IA/KN/MO vicinity) as a flat/compact southern stream shortwave and weak sfc low tracking eastward through the Ohio Valley toward the DelmarVA. Ensemble data keeps the bulk of precip and max POPs with this system along and south of the MD line centered on next Tuesday. Any shifts in the track or speed/timing could introduce some ptype issues on the northern edge of the precip. That said, this system could also skirt by far enough to the south and not bring any precip. High pressure edging southeast from the Great Lakes appears deliver a dry period around midweek/Wednesday before precip odds trend higher into the end of next week. && .AVIATION /04Z FRIDAY THROUGH TUESDAY/... SFC and satellite observations indicate clear/clearing skies as high pressure begins to build into the airspace from the southwest. VFR conditions are expected overnight for all TAF sites, but BFD. BFD is running an MVFR ceiling and reporting UP in recent SFC ob from residual lake effect. Winds there remain moderate and gusty from the northwest and guidance suggests it will be a few more hours until wind speeds diminish. Elsewhere, winds will continue to diminish into the late evening/overnight. There is low potential for LLWS this evening as surface wind gusts drop off, but model soundings from the RAP and HRRR suggest that the strongest winds will remain above 2000 feet. Friday will feature VFR conditions with lighter winds than we have seen the past few days. Outlook... Sat...Afternoon SHRA. Sun...SHRA/SN esp NW half. IFR poss. Breezy. Mon...Isold/SCT SHSN NW.
