The episode as NWS CTP wrote it up.
A surface cold front stationed across northern Pennsylvania allowed for scattered showers and thunderstorms to form in an environment with ample instability and limited shear during the afternoon and evening hours of June 25, 2025. These slow-moving showers and thunderstorms quickly became strong-to-severe with the aforementioned instability and were able to sustain and produce isolated instances of thunderstorm wind damage across Schuylkill and Clinton counties. Ample moisture in place, allowed for heavy rain with these showers and thunderstorms with water over roadways in urban areas of Centre County. A couple of lightning strikes from thunderstorms also caused structure fires during the evening, with one near Lock Haven and the other northwest of McConnellsburg.

NWS State College, PA wrote its last area forecast discussion before the first event at Jun 25, 2:46 PM EST, 59 minutes earlier.
Area Forecast Discussion National Weather Service State College PA 346 PM EDT Wed Jun 25 2025 .SYNOPSIS... * Not as hot, but nearer normal temperatures for the end of the week and into next week. It will be increasingly unsettled starting today through the last weekend in June with daily chances for heavy downpours. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... SHRA/TSRA spread out over the entire CWA, perhaps a bit more coverage over the S than earlier expectations. But, the coverage is generally 40-70pct. Many people are getting or will get wet before 10pm. The cells are moving a bit quicker than we expected, too. But, there is still a risk of excessive rainfall if a place gets more than one shot of rain. PWAT in the 1.5-1.8" range. Earlier storms did grow quickly over the srn tier where the mixed-layer CAPE is highest. SPC Meso graphics still paint >2000J/kg over all of srn PA and the rest of the Mid-Atlantic. As the forcing over the N and central counties counties to drop S thru the evening, we do expect there to be a ramp up in strength. Temps are going to hit the dewpoint overnight, so fog is a likelihood over the CWA, but most-so in the valleys where we have had rain fall. A deck of low clouds is possible, but not a slam-dunk to form over the NW. It may be difficult for it to form if it dries out too much there. A couple of showers/storms will linger for the first half of the night, but most will be gone after midnight/1 AM. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/... After any fog and low clouds dissipate in the morning, the picture on the radar will end up much the same as Wed. SHRA/TSRA pop in the late morning/early aftn. Highest coverage/PoPs look like it will be in the east. More heavy rainers and small hail/gusty winds are expected. We will see the heat worries reduce on Thursday, but a few counties along the MD border will touch 100 heat index again. Decided to make it a little easier on the WWA map and allow the current headlines to end as planned at 00Z, but add a new heat advy for those srn counties for just the daytime Thurs. No real change to Thurs PM - with storms lingering longer Thurs night than Wed night as the boundary will waggle back more to the northeast during the day but stall overnight. Mins should be a little cooler in the NE on the NE side of the front, than in the W. && .LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/... Shortwave troughing across the Ohio Valley coupled with placement in the warm sector and vicinity of a quasi-stationary boundary will spell an active period of showers and storms through the weekend. A cool front looks to approach central PA on Saturday, thus the uptick in shower/storm chances then. Passage of an upper trough axis and surface boundary may lead to a mostly dry day on Sunday if drier air can settle into the Commonwealth. Upper ridging building across the western Atlantic into eastern Canada then looks to take place downstream of a more potent shortwave trough digging across the Great Lakes early next week. Shower/storm chances will subsequently increase by Tuesday with temperatures continuing to remain near to slightly above normal. && .AVIATION /19Z WEDNESDAY THROUGH MONDAY/... Storms splattered across the state at 18Z, with only the far NW looks like it will remain dry. We'll leave a small mention of precip in BFD for another couple of hours. But, the more stable air from over the lake is moving into that area. Elsewhere, a SHRA/TSRA could hit at any time(s) between now and sunset. Much of these pulse storms will die off as we lose heating/sun. Weak boundary dropping down from the north now will drape itself over the state tonight and be stubborn to move out over the next few days. Overnight, fog is expected to develop across much of the region in the wake of showers and storms today, mainly where it ended up raining. The coverage will not be 100% of the area, and more so in the valleys. Have kept MVFR and IFR visibility at most sites for a few hrs late tonight. That should dissipate Thurs AM after just an hour or two of sun. There could be a deck of low/IFR clouds instead or in addition to any fog over the NW. The high moisture lingers for the next few days, and little change is expected to our pattern. Daily SHRA/TSRA, and any could make some heavy rain or gusty winds. Will draw up Thursday much like this aftn/evening. Outlook... Fri-Mon...Continued impacts from SHRA/TSRA, mainly in the aftns and eves. Less hot. && .CLIMATE... This should be the last really hot day for a week or more, but the current 8-14 day outlook does have a high confidence of above avg temps for PA, esp in the NW/Great Lakes. The following climate sites broke or tied their daily record temperatures: MONDAY JUNE 23, 2025 Altoona: Low of 72F broke the record of 71F set last year. Altoona: High of 93F broke the record of 90F set in 1994. Bradford: High of 89F broke the record of 86F set in 2013. Harrisburg: High of 97F tied the record set in 1965.
