The episode as NWS CTP wrote it up.
A multi-day rain event caused by a slow-moving upper-level low resulted in 1-2.5 inches of rain across central Pennsylvania. Clearfield County saw the most rain with this system, with Coal Run near DuBois briefly leaving it's banks and temporarily closing one road.

NWS State College, PA wrote its last area forecast discussion before the first event at May 22, 6:18 AM EST, 3 hours 36 minutes earlier.
Area Forecast Discussion National Weather Service State College PA 718 AM EDT Thu May 22 2025 .SYNOPSIS... * An unseasonably cool and wet stretch of weather will continue with frequent showers through the end of the week * Daytime temperatures will be 10 to 20 degrees below the historical average through Saturday with no signs of a summertime warmup on the horizon * Slight warming with lowest chance of rain Sunday & Monday * Cool/wet pattern returns next week && .NEAR TERM /UNTIL 6 PM THIS EVENING/... Stream of rain/showers pointing toward State College is right on track with forecast. Hourly rates of 0.10 to 0.20" are not concerning w.r.t. flooding. Prev... Expect the SHRA will continue to be numerous throughout the day as the upper low/trough nears. Temps remain cool and things are pretty stable. Maxes will be a little (3-4F) milder than Wed, though. Lowered LIs and CAPE try to emerge in the aftn. Will make a small chc of TS, mainly in the S. But any breaks in the clouds will help the clouds get taller. It's a question of how wide the breaks will get and how long they will be around. The wider they can get, the higher the chc for TS. Hydro concerns are pretty much nil as the heaviest of the rain has passed without fanfare. It's all just drought-defeating rain at this point. && .SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/... Pinwheeling double-barrell sfc lows beneath a large scale cyclonic upper flow/trough will maintain the cool and wet pattern into the weekend. Most of the SHRA will occur over the nrn mtns, with lower chcs to the SE. Despite the persistent upper trough, slight drying (lowering PWATs and sfc Td) and the gradual shift eastward of the system should diminish the coverage/frequency of the SHRA. That being said, cool temps aloft will still support scattered showers and cloudy conditions. We may see some improvement in southeast PA by Saturday afternoon with a few breaks in the clouds thanks to downsloping northwest flow, but cool temps and mostly cloudy skies are a good bet for the majority of the area for the majority of the short term period. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... If you squint really hard at the upper air charts for Sunday, you might be able to convince yourself that upper level flow is becoming slightly less trough-y, but that's probably just wishful thinking. We are growing less optimistic to see any marked improvement before Monday. The recent blocking pattern has proven to be rather persistent and in no hurry to unravel. The cyclonic flow and cool temps aloft should translate into a good deal of cloud cover with POPs peaking during the afternoon hours coincident with diurnal heating. Precip probs should bottom on Monday before ramping higher into Tuesday-Wednesday. Models are coming into better agreement in tracking the southern stream wave farther to the north. There are even signs that the briefly split-stream flow will try to close off into another upper low in the Great Lakes/Ohio Valley region by the middle of next week. So it appears the cool and wet pattern will continue into the end of the month with no signs of summer weather on the horizon (meteorological summer begins on June 1). && .AVIATION /11Z THURSDAY THROUGH MONDAY/... A fairly organized batch of showers are currently (as of 11Z/7AM EDT) being observed across central Pennsylvania with ceilings dropping towards IFR thresholds at most airfields. While some airfields (notably UNV) are remaining MVFR ceilings remain extremely borderline and generally expect IFR to prevail over the next couple of hours. LIFR conditions at JST are expected to linger (based on GLAMP/HREF guidance) over the next couple of hours before prevailing IFR after 16Z Thu. Some improvement towards MVFR is progged by the bulk of model guidance between 19Z Thu and 00Z Fri at all airfields except JST/BFD/AOO, thus have started to allow conditions to improve slightly given recent model trends. Timing of low-level ceilings lifting remains questionable and model guidance is not as keen as previous cycles; however, have noted some low-level dry conditions in model soundings that suggest some scattering out of IFR cloud decks, allowing for some window of MVFR ceilings with low-to-moderate (30-40%) confidence. Have opted to keep these MVFR ceilings in this TAF package due to previous model trends; however it is not out of the question that high-end IFR ceilings hang around at IPT/UNV. Some potential exists for thunderstorms across the southeastern periphery of the forecast area between 16-22Z Thu; however, low confidence (~20%) on any impacts at MDT/LNS so have opted for no mention in this TAF package. Dry conditions are increasingly likely based on a consensus of GLAMP/HREF guidance across MDT/LNS towards the end of the TAF period, generally after 05Z Fri, with moderate (~50-60%) confidence. Recent guidance does indicate some signals for UNV/IPT to prevail with short-lived dry conditions towards the end of the 12Z TAF package and have started outlining this trend in the most recent forecast. For airfields further north/west, low-level moisture remains in place on recent RAP model soundings, thus moderate (50-60%) confidence on showers remaining at BFD/JST/AOO through 12Z Fri. Outlook... Fri...Ocnl SHRA. Sat-Mon...Still a chance of a shower. && .CTP WATCHES/WARNINGS/ADVISORIES...
