Two rounds of convection impacted Pennsylvania on July 24, 2022. The first round of convection involved a cluster of storms that pushed across the northern mountains (along and north of I-80) during the afternoon hours, producing sporadic wind damage.

The episode as NWS CTP wrote it up.
Two rounds of convection impacted Pennsylvania on July 24, 2022. The first round of convection involved a cluster of storms that pushed across the northern mountains (along and north of I-80) during the afternoon hours, producing sporadic wind damage. The second round of convection was in the form of a line of thunderstorms just ahead of a cold front approaching northwestern Pennsylvania from the Great Lakes during the late evening of July 24 into the early morning hours of July 25. This second round of convection produced sporadic wind damage across northwestern Pennsylvania before weakening as it progressed southeastward overnight.

Area Forecast Discussion National Weather Service State College PA 140 PM EDT Sun Jul 24 2022 .SYNOPSIS... A cold front over the Great Lakes will push southeast across Pennsylvania late tonight and Monday. High pressure will build over the region Tuesday, than a warm front will lift into the region by midweek. && .NEAR TERM /THROUGH TONIGHT/... Boundary which came on-shore an hour or so ago may be responsible for the current cell development over NWrn PA. Thus far, only one decent cell over PBZ's nrn counties has be beefy enough to grow severe. Expect some increase in coverage thru the next hour or two. If the sfc-based CIN and warmish mid-levels can be eroded enough, we may be in need of a watch across our nrn tier or two of counties. SPC MCD covers that portion of our area. Cold front won't arrive for 12 or so hours in the NW, but that continues to look like the highest coverage/chance for storms. A nearly solid line is anticipated with/just ahead of the front, but dir shear is higher in the warm sector. Supercells still possible with mean storm motions from 240deg, and deep layer shear from the NW >30kts. RAP and HRRR both want to pop a few discrete cells over wrn PA not far from the CWA border around noon, and roll them across the northern half of the area this aftn. lake breeze (or perhaps just the current remnant boundary moving on-shore now) might contribute to convective initiation today as well over the NW this aftn. Cooling of boundary layer should result in a diminishing risk of severe weather (early?) this evening. More storms are expected later tonight as the front nears and shear increases again. The high PWATs and repeated cell passages which are possible could make some minor flooding. But, cell speed/residence time could keep the threat for more-serious (flash) flooding low. Expect the front to drop about half way through the area overnight. As it does so, it will be working into more stable air. This should decrease the severity of the storms, and coverage should also become more spotty. Temps will stay up above normal for one more night, but cooler air starts to filter into the northern third of the area overnight. && .SHORT TERM /MONDAY/... Convection should ramp up along the cold front, as it pushes into southeast PA Monday afternoon, while drier/cooler air continues to take over across the northwestern counties. Although cloud cover should hold temperatures down, strong mid level flow and associated deep layer shear, combined with dewpoints in the low 70s, should support organized convection and possible isolated supercells across parts of the Lower Susq Valley. Many models drop the rain south of the area by sunset, but lingering a chc in Lancaster Co is always a good idea. Maxes will be 10F lower than Sunday in the N and W and 5F or more cooler in the SE. && .LONG TERM /MONDAY NIGHT THROUGH SUNDAY/... Overall just minor changes to the longer term grids. High pressure and associated dry air mass should support fair and seasonable conditions Monday night and Tuesday. However, a stalling cold front south of Pennsylvania will remain just close enough to warrant the slight chance of a shower over the southern tier counties into Tuesday. Went a bit lower in some spots for POPS Wednesday into Thursday. Upper level support with this system looking a bit weaker now. Went a tad cooler across the southeast Wednesday night. Slightly less humid air and mainly dry weather is likely to close out the week. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... VFR at 15Z this morning across all airfields. Rounds of scattered SHRA/TSRA are expected this afternoon and evening with the potential for gusty winds in any TSRA, especially at BFD. The first round of storms will be after 18Z, then the second round will be after 3Z. Expect MVFR to IFR restrictions in SHRA/TSRA. High density altitude will be a concern again due to the heat. Expect to need longer takeoff distances. SHRA/TSRA will continue through the night and into Monday with a CFROPA. Outlook... Mon...SHRA/TSRA, especially SE, with the passage of a cold front Tues...Mainly VFR. Wed...Mainly VFR, TSRA/restrictions poss W. Wed night-Thurs...Numerous SHRA/TSRA and flight restrictions expected. && .CLIMATE...
