A very warm and moist warm sector airmass was present in advance of a cold front over the Lower Great Lakes and south of warm front from upstate NY into eastern MA. This lead to the development of isolated thunderstorms which produced strong to locally damaging winds across northern PA during the late afternoon and evening hours.

The episode as NWS CTP wrote it up.
A very warm and moist warm sector airmass was present in advance of a cold front over the Lower Great Lakes and south of warm front from upstate NY into eastern MA. This lead to the development of isolated thunderstorms which produced strong to locally damaging winds across northern PA during the late afternoon and evening hours.
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 Aug 13, 2:20 PM EST, 50 minutes earlier.
Area Forecast Discussion National Weather Service State College PA 320 PM EDT SAT AUG 13 2016 .SYNOPSIS... Hot and Humid weather will persist across Central Pennsylvania through Sunday. Warm and muggy overnight tonight followed by Excessive heat conditions again in the lower to middle Susquehanna Valley again on Sunday. Heat indices of 100 to 108 degrees are expected during the afternoon and early evening.The heat and humidity will continue to support scattered thunderstorms. Storms may produce frequent lightning and heavy rainfall with the risk for some localized flooding. && .NEAR TERM /THROUGH TONIGHT/... Scattered storms across the region this afternoon with dew points in the in 70s. Heat indices were in the 100 to 105 range over the Lower and middle Susquehanna Valley until some locations saw temperatures drop from thunderstorms. Muggy conditions again tonight. High Dew point temperatures continue in the 70s. Little relief for those without AC tonight. Convective allowing models continue isolated to scattered convection though about 06z. With the high humidity, there has been a lot of cloud to ground lightning strikes with these storms. Very weak frontal boundary to drop southeast from the Great Lakes washes out. Still it may be helping to keep some of the convection going. && .SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/... General pattern continues with the upper level ridge off the Southeast Coast and a trough over the Upper MS Valley. A warm humid southwest flow continues into PA with short-waves moving through. Hence the hot muggy pattern with scattered thunderstorms will continue. Excessive heat warning for the Lower Susq Valley to Harrisburg continues with a Heat Advisory for counties surrounding that up to Williamsburg and west out to Franklin County. With the washed out frontal boundary and high PWs there remains a concern for heavy rain and localized flooding if storms stall or multiple storms move across the same location. && .LONG TERM /MONDAY THROUGH SATURDAY/... Storms will be more isolated Monday with weak ridging over the area. Heavy downpours still possible in storms but lower chances than Sunday. Dew points will be about 5 to 10 degrees lower and high temperatures will not be in the 80s and hence the heat indices will not be as high. Should feel a bit more comfortable for people. Warm front returns Tuesday with another short-wave moving northeast out of the Ohio Valley. Likely to see scattered thunderstorms across central PA with warm and humid conditions back. High temperatures will not be as high as the last few days though. Scattered showers and thunderstorms possible each day from Wednesday into Saturday with Friday having the lowest chances. && .AVIATION /19Z SATURDAY THROUGH THURSDAY/... scattered thunderstorms across the region with local heavy rain and gusty winds producing brief IFR condition. Outside of storms it is generally VFR. Storms will diminish overnight but isolated storms are still possible. Some areas of light fog and haze is likely overnight particularly in areas that recieved a good rain. Sunday looks to be a repeat. A cold front could bring drier air in by late Monday, which would decrease the chance of convection by then. Outlook... Fri-Mon...Localized restrictions in scattered to numerous mainly afternoon shra/tsra. Tue...Patchy fog possible early...otherwise mainly VFR. && .CTP WATCHES/WARNINGS/ADVISORIES... Heat Advisory until 6 PM EDT Sunday for PAZ028-036-046-049>053- 056-058-063-064.
