499 FXUS61 KCTP 020754 AFDCTP Area Forecast Discussion National Weather Service State College PA 254 AM EST Sun Nov 2 2025 .SYNOPSIS... * Seasonable and dry for most of central PA through Tuesday * Rounds/bouts of showers from Wednesday through the weekend * Several breezy to windy periods during the upcoming week && .NEAR TERM /THROUGH TONIGHT/... Goodbye to daylight saving time and hello to standard time on this turn back the clock/first Sunday of November. Partly sunny and seasonable conditions will close out the weekend with highs ticking a bit higher vs. Saturday (particularly across the NW Alleghenies) into the mid 50s to low 60s. CPA will be in a narrow dry wedge/rain-free zone between a northern stream trough moving through the Great Lakes and a southern stream closed low tracking from southeast MO across the southern Appalachians. Some light rain tied to these synoptic features could approach the far northwest and southeast corners of the CWA by 12Z Monday, but the latest hires ensemble data keeps POPs at or below 10%. Sky cover tonight should range from mainly clear to partly cloudy from NW to SE with min temps in the 30-40F range. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... Low amplitude zonal flow pattern develops across the country this week with a series of progressive troughs/disturbances moving quickly from west to east. The first upper trough and moisture-starved cold front will swing through the region on Monday followed by breezy conditions into Tuesday. Max gusts in the 20-30 mph range are expected across the northwest 1/2 of the CWA, but may not be high enough based on fcst sounding data. A couple showers are possible downwind of Lake Erie across the northern tier Monday afternoon, but the overall lake effect response does not look very impressive. Seasonal temps on balance through the short term with highs trending slightly lower on Tuesday (lower 50s to near 60F). && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... Model guidance remains in good agreement on the overall large scale pattern, with differences in the details of individual systems. The most uncertain part of forecast is the timing of each fast moving system as it moves across the country within the progressive northern stream flow - particularly late in the period/over the weekend. For now, precip chances remain focused inside the 18Z Wed-18Z Thu window with perhaps two additional bouts of showers between Friday PM and Sunday. Expect a breezy to windy period to accompany and follow each passing upper wave and associated sfc cold front. Low level temps are marginally cold enough to support rain/snow showers over the NW mtns Wednesday night with a slightly more robust signal for snow showers Saturday night into Sunday over the higher elevations. && .AVIATION /06Z SUNDAY THROUGH THURSDAY/... Weak high pressure building into the Keystone state will provide the area with dry weather and VFR conditions into at least early Monday. Lingering stratus in the northwest has bases between 4000 and 6000 ft. Otherwise, mainly seeing high cirrus across central PA associated with an upper trough. Winds will remain light through Sunday night. Much of the stormy weather in the coming week will miss us to the south. Weak low pressure systems tracking across the north will have little moisture to work with. The main issue from time to time in the coming week will be gusty winds. Outlook... Mon...Increasing chance of rain showers and possible restrictions, mainly in the northwest late in the day. Gusty SW to W winds. Tue...Mainly VFR with a gusty northwest wind. Wed...Increasing clouds with a chance of showers. Restrictions possible in the N/W, otherwise VFR. Thu...Showers/restrictions possible early, improving late. && .CTP WATCHES/WARNINGS/ADVISORIES... None. && $$ SYNOPSIS...Steinbugl NEAR TERM...Steinbugl SHORT TERM...Steinbugl LONG TERM...Steinbugl AVIATION...Colbert
