031 FXUS61 KCTP 030704 AFDCTP Area Forecast Discussion National Weather Service State College PA 204 AM EST Mon Nov 3 2025 .SYNOPSIS... * Seasonable and dry for most of central PA through Tuesday * Chances of precipitation limited to northern PA on Monday. * Rounds/bouts of showers from Wednesday through the weekend. * Several breezy to windy periods during the upcoming week. && .NEAR TERM /UNTIL 9 AM THIS MORNING/... Lower clouds trying to creep in from the west, but not doing so very quickly. Subsidence under the big sfc high will likely squash them anyway. Otherwise, it`s just the anti-cyclonically curved high clouds generated by the low to our south. Those are of no consequence...not even to the overnight temps. BFD is just a deg away from the forecast min there, but dewpoint is just a deg lower. So, some safety there. But, we`ll notch temps lower in the NW just to be sure. Prev... Surface high pressure currently observed near the PA/NJ border will gradually continue drifting eastward off the Atlantic Coast this evening. Mostly dry conditions are expected in the near- term with radar echos across northern Maryland having to contend with dry air to get to the surface. Cloud cover across western Pennsylvania will gradually diminish this evening, with recent HREF model guidance indicating increasing low-level cloud decks this evening and overnight. Minimum temperatures overnight into Monday morning will generally range from the mid-30s across the northwest where radiational cooling will allow for slightly cooler temperatures to the lower 40s across the southeast where clouds are expected to linger tonight. && .SHORT TERM /9 AM THIS MORNING THROUGH TUESDAY NIGHT/... Zonal flow pattern begins to take hold across the country this week with the first of multiple progressive troughs crossing the region on Monday with an associated cold front in the afternoon hours. The air mass associated with this trough will remain fairly dry, with PWATs in the 0.25-0.50" range. Any shower activity on Monday will be limited downwind of Lake Erie with current forecast slightly increasing PoPs in the late Monday afternoon/early evening timeframe. Cold front passage will bring about gusty winds across the region beginning Monday afternoon and continuing into Tuesday. At this time, forecast wind gusts in the 20-30 mph range, with the ceiling closer to the 30-40 mph range. Given this ceiling, no flags out for a Wind Advisory this cycle, although will need to continue to monitor trends in model guidance/forecast sounding data. Widespread dry conditions are in the forecast by early Tuesday morning, with any residual showers limited to far western Warren County with any remaining lake response. Any lingering precipitation is expected to taper off quickly by sunrise, giving way to dry conditions with mostly sunny skies and mild temperatures on Tuesday. Clouds begin to increase later in the short-term period (Tuesday Night) ahead of the next system that will approach central Pennsylvania for the middle of the week. && .LONG TERM /WEDNESDAY THROUGH SUNDAY/... The bulk of model guidance remains to outline fair agreement with regards to the large-scale pattern with the most uncertain aspect of the forecast manifesting with regards to timing of individual disturbances. Model guidance continues to hone in on the Wednesday afternoon into early Thursday morning for the middle of the week disturbance, with slightly more uncertainty/activity this upcoming weekend. Current forecast outlines some potential for rain/snow showers Wednesday night into Thursday morning, especially for areas north of I-80 due to sufficient low-level temperatures; however, better chances for snow will come across higher elevations Saturday night into Sunday morning along with Sunday evening into Monday morning. && .AVIATION /07Z MONDAY THROUGH FRIDAY/... Central PA airspace will be in between two weather systems overnight into late Monday morning, and with high pressure overhead VFR conds are expected through the period. Later this morning, gusty winds could become an issue as a fast moving cold front moves across the area. Gusty winds likely to linger into Tuesday. The front has limited moisture to work with. Highest chance of a shower would be BFD. Some hints that a few showers could work in from the southeast into MDT and LNS on Monday as well, given a low to our south. Left these two sites dry for now, as we would be on the extreme northern edge of this system. Overall much of the stormy weather this week will stay 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 will be gusty winds and bands of fast moving light showers. Outlook... 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. Fri...Increasing clouds with more in the way of widespread showers. Restrictions possible. Becoming windy. && .CTP WATCHES/WARNINGS/ADVISORIES... None. && $$ SYNOPSIS...Steinbugl/NPB NEAR TERM...Dangelo/NPB SHORT TERM...NPB LONG TERM...Steinbugl/NPB AVIATION...Martin/Gartner
