849 FXUS61 KCTP 122329 AFDCTP Area Forecast Discussion National Weather Service State College PA 629 PM EST Thu Feb 12 2026 .WHAT HAS CHANGED... * Adjusted snow chances up a bit through this afternoon - still only minor or no accumulation expected. * Forecast highly similar to prior forecast packages. && .KEY MESSAGES... 1) Light snow accumulations northwest today and this evening. 2) Winter weather threat for Sun-Sun night timeframe continues, with very minor changes. Medium chance PoPs southern PA, but still a 20 PoP all the way to the NY border. 3) Warmup in store for next week. && .DISCUSSION... KEY MESSAGE 1: Light snow accumulations northwest today and this evening. Low-mid level northwesterly flow helping to drive continued snow showers from northwest into central PA this afternoon. As upper troughing lifts out to the northeast, allowing for surface ridging to build in and inversion heights to lower, weakly organized bands of snow showers will gradually dwindle this evening. Of course, the constant flow of moisture uphill into the Allegheny Plateau and the highest peaks of the Commonwealth will help produce snowfall. Accumulations will be minor. Clouds are lasting quite a bit farther downstream than the blend of models suggests, and have nudged them upward throughout the next 12 hrs. The cloud cover and cold air in place will keep max temperatures today down in the 20s to lower 30s. -------------------------- KEY MESSAGE 2: Winter weather threat for Sun-Sun night timeframe continues, with very minor changes. Medium chance PoPs southern PA, but still a 20 PoP all the way to the NY border. A fast-moving low pressure system is still expected to move W-E across the southern half of the CONUS this weekend. Ensembles continue to be clustered around a Sun-Sun night timeframe when precip might make it as far north as central PA. So, confidence is the same to a little higher that Monday will be generally dry. NBM PoPs look fine for this range, and have decreased very slightly on the whole due to the trend southward and faster/flatter. The ECMWF has waggled northward and now paints 0.10-0.20" QPF along the MD border. Temps are still marginal for any frozen precip in the S (best signal is for rain there) but move north of the PA Turnpike, the temp profile would suggest a rain/snow mix or snow. Of course, it should be highlighted that we only have chc PoPs at this point. So, there isn`t a 40 pct chc of accumulating snow - just a 40pct chc that any measurable precipitation will occur. If any of the (potential) precip arrives during the daylight, as currently hinted by the preponderance of models/ensemble members, temps will be more favorable for rain. Progged temp spread on Sunday is still wider than allows for high confidence in any precip type. Middle of the road maxes are around 40F N for most of the CTP CWA, and 40-45F in the valleys of the south- central mtns where the PoPs are actually the highest. In the end, we`ve made only small tweaks to this part of the forecast vs the straight-up NBM output. -------------------------- KEY MESSAGE 3: Warmup in store for next week. Temps still on track to warm for early-mid next week as heights rise on the eastern periphery of upper ridging migrating from the Intermountain West into the central U.S. Many towns in the srn third of the CWA could rise into the 50s for maxes each day mid-week. Precip chances look very low to nil Mon & Tue as warm advection occurs with PA devoid of sufficient deeper layer moisture. Min temperatures Tue night may stay above freezing for most. Medium confidence exists in a low pressure area or two rolling W-E into the OH Valley and Mid-Atlantic along a front dropping down into PA in the midweek timeframe. Confidence in the equatorward progress that the front makes before waggling north again is low. Even if the front drops in, temps should remain above normal on Thursday. && .AVIATION /00Z FRIDAY THROUGH TUESDAY/... Scattered snow showers at BFD and JST will gradually taper off through the rest of the evening as high pressure builds in from the west. Expect ceilings to gradually lower into the overnight hours, with BFD likely to see IFR ceilings for much of the night. Brief periods of IFR ceilings are possible (~60% chance) at JST as well, but low-end MVFR is more likely to prevail. Model RH profiles show MVFR ceilings redeveloping at AOO and UNV between 03Z and 05Z, but airfields farther to the east will remain VFR. Skies will clear out after sunrise from southeast to northwest, giving way to VFR conditions area-wide by mid- afternoon. Outlook... Sat...Low ceilings early north of KUNV along with a few snow showers. VFR for the afternoon. Sun-Tue...Monitoring potential for winter weather on Sunday and Monday. Most likely restrictions are in southern PA at this time. Tuesday looks dry and VFR. && .CTP WATCHES/WARNINGS/ADVISORIES... None. && $$ WHAT HAS CHANGED...Guseman/Dangelo KEY MESSAGES...Guseman/Dangelo DISCUSSION...Guseman/Dangelo AVIATION...Bauco |
