350 FXUS61 KCTP 170432 AFDCTP Area Forecast Discussion National Weather Service State College PA 1132 PM EST Sun Nov 16 2025 .SYNOPSIS... * Windy and colder with lake effect snow bands lasting into Monday; snowy road conditions/hazardous travel possible in blowing/drifting snow * Light rain/snow possible Tuesday followed by a slightly milder trend through the middle of next week && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... The character of the snow showers is expected to transition from cellular to more of the typical streamer band lake effect appearance with the loss of daytime heating and increasing boundary layer RH, resulting in a greater likelihood of accumulating snowfall over northwest PA. A stripe of 5 to 8 inches of snow is expected somewhere in the area covered by the Lake Effect Snow Warning (perhaps not county-wide averages, as lake effect bands are typically more narrow), while areas covered by the Winter Weather Advisory should see snowfall in the 2 to 5 inch range. High res guidance continues to show the potential for some of these bands/squalls to reach pretty far inland overnight, potentially even extending into the Lower Susquehanna Valley. These bands may cause rapid changes in visibility and quick accumulations on roadways, leading to hazardous travel conditions. The other concern today is strong winds. Gusts of 40 to 50 mph will be likely through the rest of the afternoon along with a few gusts as high as 55 mph as we continue to tap into 50 knot winds at the top of the mixed layer. These winds could blow around any unsecured objects and may result in scattered power outages. Wind stay strong overnight, with gusts of 30 to 40 mph likely. A Wind Advisory remains in effect for the entire CWA through midnight. && .SHORT TERM /6 AM MONDAY MORNING THROUGH 6 PM MONDAY/... Snow showers gradually decrease in coverage through the day on Monday as inversion heights begin to fall, though it likely takes most of the day for snow to come to an end across the northern tier. High temperatures will range from the low 30s to the mid 40s. Winds will remain gusty, though likely not as strong as on Sunday, with gusts in the 30 to 40 mph range. && .LONG TERM /MONDAY NIGHT THROUGH SUNDAY/... Snow showers and gusty winds taper off Monday night as high pressure briefly builds into the region. 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. Consensus brings about 0.25 inch of QPF across the southern tier, and just a few hundredths north of Interstate 80. There could be some snow on the leading edge especially Tuesday morning, but generally limited to a coating. 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. Most guidance shows this system tracking to our west, which would result in an all rain scenario. && .AVIATION /06Z MONDAY THROUGH FRIDAY/... Lake effect snow showers will continue to affect BFD and perhaps UNV tonight into at least the first half of Tuesday. IFR or LIFR visibilities (and MVFR ceilings) will prevail at BFD for much of the overnight hours before the lake effect snow band drifts south of the airfield late tonight. The snow band may then drift back north over the airfield during the day on Monday, bringing an additional period of IFR or MVFR restrictions. The snow band could also bring restrictions to UNV, with MVFR as the most likely category. Other airfields are progged to maintain VFR conditions through the TAF period. If the snow band can maintain its structure far enough southeast, it could bring some rain or snow to KMDT, though any restrictions should be very brief (if at all). Gusty winds will slacken somewhat overnight, generally blowing out of the northwest at 15 to 25kts. Winds will continue to weaken through Tuesday morning. Outlook... Tues...Restrictions likely in rain and snow. Wed-Thu...Isolated showers, restrictions likely from southeast flow/low clouds. Fri...Widespread rain expected. && .CTP WATCHES/WARNINGS/ADVISORIES... Lake Effect Snow Warning until 1 PM EST Monday for PAZ004-005- 010. Winter Weather Advisory until 1 PM EST Monday for PAZ006-011- 017. && $$ SYNOPSIS...Dangelo NEAR TERM...Colbert/Bauco SHORT TERM...Dangelo/Bauco LONG TERM...Colbert/Bauco AVIATION...Banghoff
