Severe (D2) drought across north-central Pennsylvania towards the tail end of October continued into the early stages of November, with beneficial rainfall during the last week of October and early November allowing for improvement in drought conditions. Severe drought was removed from north-central Pennsylvania on November 4, 2025.

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS State College, PA wrote its last area forecast discussion before the first event at Oct 31, 8:23 PM EST, 3 hours 37 minutes earlier.
Area Forecast Discussion National Weather Service State College PA 923 PM EDT Fri Oct 31 2025 .SYNOPSIS... * Mainly dry and seasonable this weekend * The next best chance for showers is on Monday && .NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... Wind gusts are diminishing and should be below advy levels for much of the area. However, we'll leave it running til natural end (midnight) for the N and NE where a couple of gusts nearby are still AOA 40KT. Otherwise, the near term obs have a little more warmth in them than the forecast, likely due to the clouds and well-mixed llvls. Will nudge them appropriately. && .SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY NIGHT/... 1 pm update... This weekend, the aforementioned stacked cyclone is expected to continue to lift northward through eastern Canada, gradually losing its grip on the Commonwealth. At the same time, another piece of energy aloft drops into the southeastern states, with most of the moisture and DPVA bypassing PA to the W and S. By Sunday, the flow becomes sufficiently anticyclonic in the lower levels to minimize any residual impacts of wrap-around moisture, with a surface high building into the northeastern and Mid-Atlantic states. The above pattern evolution should translate to diminishing coverage of showers for northwest PA overnight into early Saturday, followed by a mainly dry weekend thereafter. Breaks of sunshine should become more prevalent with time, as wrap-around moisture/cloud cover gets pushed northward, as alluded to above. Thicker clouds and any shower activity tied to the southern piece of energy should get shunted well south of PA. && .LONG TERM /MONDAY THROUGH FRIDAY/... Although small model core differences exist, cluster analysis signals next week show an increasingly zonal, energetic northern stream from the north Pacific all the way across the northern tier of the CONUS. This pattern should bring fast moving, generally moisture starved systems across PA about every 2-3 days, each one bringing a bout of light rainfall. The first of these disturbances is most likely to bring showers to the region by later Monday, with another potential system later Wednesday into Thursday. Given the lack of flow amplification, no significant temperature anomalies are foreseen next week (near normal temperatures for early November), and the threat for heavy precipitation also appears low, given seemingly insufficient opportunities to tap Gulf moisture. && .AVIATION /01Z SATURDAY THROUGH WEDNESDAY/... A deep low will continue to quickly pull northeast away from our area. Main thing this evening will be gusty winds. The winds will slowly weaken late, before picking back up again after around 14Z on Saturday. Winds on Saturday will not be as strong as today. Looking at mainly VFR CIGS all areas overnight into the weekend. BFD could go MVFR for brief times, especially near any showers. Most of the showers will be to the north at BFD, so used VCSH for showers there into Saturday. Sunday should feature dry weather with much less wind, as high pressure builds into the area. Main weather system early next week is across the southeast. Weaker systems tracking eastward across the northern tier states on Monday and later in the week will have limited moisture to work with, given that the main weather systems will be over the southern states. Outlook... Sun...VFR conditions. Mon...Increasing chance of rain showers and possible restrictions, mainly in the northwest late in the day. Tue...Mainly VFR with a breezy west wind. Wed...VFR conditions. && .CLIMATE...
