Area Forecast Discussion National Weather Service State College PA 716 PM EDT Sat May 25 2019 .SYNOPSIS... Warm temperatures and high humidity will last into Sunday. Showers and thunderstorms will also be around, mainly during the afternoon and evening hours each day. Memorial Day will feature near normal temperatures and comfortably lower humidity. A few more rounds of showers and scattered thunderstorms with gusty wind and locally heavy rain appear likely for both Tuesday and Wednesday afternoons and evenings. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... Severe Watch #243 in effect for my western strip of counties (Warren/McKean southward to Somerset County) until 02z. Lake breeze starting to light up as expected, as large scale upper level forcing interacts with the lake boundary over northwest PA. CAMs indicate a squall line with embedded supercells pushing east of the Alleghenies after 00z. Added my western counties into watch that SPC had proposed for western PA. 40-50KTs of deep-layer shear indicates supercells likely, but LCLs don't favor a sig tornado threat. High moisture flux over western PA with PW surging above normal. Main threat for excessive rainfall is more where multiple cells cross a point, but flash flooding threat is on the low side. The storms should be gone from BFD by 01Z, IPT/UNV by 03Z and the srn cities by 05Z or 06Z at the latest. The wind does not die off completely, but fog could form in the wake of the storms where the sky initially clears out. Much drier air will dip into nrn PA overnight. Mins will be still be in the 60s, though, and it will stay muggy for the srn half or more of the CWA. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH 6 PM SUNDAY/... Muggy air will hang around the srn half of the state on Sunday. Additional showers and storms will fire up - with the SWrn part of the CWA still in a MRGL to SLGT risk for excessive rainfall. Will nudge the PoPs a little higher for the SW, and downward a notch for the nrn tier. Max temps will be a little cooler than Sat in the N and W, but warmer by a deg or two in the SE thanks to the downslope flow. MRGL-SLGT risk for severe still exists in roughly the same area as the ERO, but a little farther to the south where the best instability will be. && .LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/... 110 pm update... On the large-scale, a western CONUS upper trough/eastern CONUS upper ridge pattern still looks to prevail for most of next week, before the ridge flattens a bit towards next weekend, as an eastern Canadian trough perhaps builds southward. In general, this means continued warm temperatures through at least mid-week, perhaps cooling towards the end of the period. As for the daily sensible weather, as a cold front settles south of the Commonwealth and high pressure noses down from Canada, we should dry out Sunday night, with a nice Memorial Day likely on tap. On Tuesday, a warm front should approach from the south and west, with this boundary probably stalling out somewhere near or over the Commonwealth Wednesday-Thursday. This means that unsettled weather comes back into the forecast, with daily chances for showers and thunderstorms. A cold front may sweep much of the moisture south and east of the region for the end of the week, with cooler and drier weather possible at that time frame. Daily highs will mostly range from the mid 70s-mid 80s through at least Thursday, with some cooling anticipated thereafter. && .AVIATION /23Z SATURDAY THROUGH THURSDAY/... For the 00Z TAF package, adjusted the timing of storms some more. First band of showers and storms move east of the mountains and is now mainly gone now. Another line of storms formed east of the southwest Ontario line of storms. This is the line I adjusted for in the TAFS. The cold front sags southward overnight, but will be close to the southern part of the Keystone state on Sunday, thus used VCSH across the south. Less chance of showers and storms on Memorial day. Some chance of more showers and storms again after Monday. .Outlook... Mon-Tues AM...VFR. Tues PM-Thurs...Mainly VFR, although spotty showers/storms are expected each aftn/evening. && .CTP WATCHES/WARNINGS/ADVISORIES... None. && SYNOPSIS...Dangelo NEAR TERM...Dangelo/DeVoir SHORT TERM...Dangelo LONG TERM...Jurewicz AVIATION...Martin
