942 FXUS61 KCTP 122326 AFDCTP Area Forecast Discussion National Weather Service State College PA 626 PM EST Wed Nov 12 2025 .SYNOPSIS... * Breezy with rain/snow showers lingering across parts of western and northern Pennsylvania through Thursday * Mainly dry Friday; shot of rain to start the weekend before transitioning to snow showers Sunday into Monday * Temperatures gradually moderate into the weekend before trending colder with gusty winds returning Sunday-Monday && .NEAR TERM /THROUGH THURSDAY/... Partly to mostly cloudy and breezy tonight with light rain/snow showers lingering across the northern tier. Minor accumulations of generally 0.5" or less are expected through 12Z Thu in the NW mtns. Lows will be modulated by the westerly breeze and cloud cover extending downwind of Lake Erie holding temps in the 30-40F range. With G4 or greater severe geomagnetic solar storm forecast by SWPC, the best Aurora viewing will likely be with any clearing to the southeast of the Allegheny Front across the southeastern half of the CWA. && .SHORT TERM /THURSDAY NIGHT/... Upper-level trough gradually shifts to the northeast through the end of the week. Persistent NW flow will maintain occasional rain and snow showers downwind of Lake Erie across parts of north central PA through Thursday. High pressure sliding eastward will lower inversion heights and eventually shut off the lake effect by Friday. Clouds will be prevalent in the NW Alleghenies while more peaks of sun will be found farther to the southeast into the LSV. Thursday will remain breezy, but winds will gradually trend lower on Friday. Max temps trend warmer by a couple of degrees through late week with highs in the low 40s-50s on Friday (near to slightly below mid November climo). Best odds for dry wx/no precip window looks like 12Z Friday to 18Z Saturday. && .LONG TERM /FRIDAY THROUGH WEDNESDAY/... Northern stream upper trough and attendant a sfc low/frontal system will dive southeast across the Great Lakes and Northeast this weekend, leading to a period of rain later Saturday into Saturday night. Can`t rule out a few thunderstorms primarily over western PA in a warm sector airmass likely characterized by limited CAPE and strong shear. Breezy to windy conditions will accompany the passage of the frontal system with colder air poised to return on Sunday. The gusty NW flow should send lake enhanced snow showers/bands back into NW PA to close out the weekend and start next week. The next system is fcst to eject eastward across the north central Plains and quickly spread precip downstream through the Ohio Valley early next week. Aside from the operational GFS, there is a reasonable consensus for precip to reach the area by Tuesday. Thermal profiles appear to be supportive of potential mixed ptypes on the front-end of precip depending on speed/time of arrival. && .AVIATION /00Z THURSDAY THROUGH MONDAY/... Upper ridging will slowly build in tonight and Thurs. Lake effect clouds will linger into Thursday, though, before diminishing and lifting N of PA. Clouds are mainly VFR except BFD where IFR remains. This should be the case much of the night. But, some clearing will ensue shortly, and leave MDT/LNS without much if any cloud cover for the second half of the night. The sfc high to our SW doesn`t advance much tonight or Thurs. Therefore, while the wind gets less gusty tonight due to lack of daytime mixing, they will pick up again 13-14Z and some gusts could touch the 30KT mark, mainly in the srn terminals. Outlook...
