Area forecast discussion, Jun 3, 6:42 PM EDT, 6 minutes before
Area Forecast Discussion National Weather Service State College PA 642 PM EDT Wed Jun 3 2020 .SYNOPSIS... Additional showers and thunderstorms will drift into southern PA this evening, as a frontal boundary pushes through the commonwealth. It will remain unsettled Thursday into Friday, and possibly right into the weekend. High pressure and dry air should finally take hold Sunday and last into early next week. && .NEAR TERM /UNTIL MIDNIGHT TONIGHT/... At 23z, showers and storms are becoming more confined to the southeastern half of the commonwealth, as a front drops into NW PA. Some of these storms have produced wind damage and hail, and one long-lived supercell traveled from Cameron County in NW PA southeastward and is now impacting eastern Lancaster County. A drier airmass will begin settling into northern PA by midnight, with dewpoints dropping into the 50s. && .SHORT TERM /MIDNIGHT THROUGH 6 PM THURSDAY/... Shower and thunderstorm activity should diminish heading into the overnight hours. Clearing skies will spread south across the region, but may self-destruct and turn to some patchy fog. Low clouds are also possible where the wind continues to upslope into the Alleghenies. Storms/showers will diminish for everyone but they could hang on until around or shortly after midnight across the Laurels. Sticky air will keep the temps from falling out of the mid 60s for southern PA, though clearing skies and drier air will allow the nrn mtns to dip into the 50s. The old boundary will linger along the srn border into Thurs. Upper flow flattens to a W-E direction, and lingering moisture and daytime heating will lead to showers and storms redeveloping in the aftn. Shear will be lacking, but CAPEs could reach 1000 or better across the south. SPC MRGL risk is enough to keep a close eye on any storms. Max temps Thurs will be just as warm across the north as the south, thanks to more sun up north. The coolest place will be the Laurels where clouds and a higher chc of showers exist. && .LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/... The old front will stall near the PA-MD border on Thu, keeping a chance of rain showers and maybe a few PM tstms through Fri. Generally a quarter to half an inch of rain is expected across the southern counties Thu-Fri, with locally higher amounts in storms. Lesser amounts north. The stationary front is progged to move offshore Fri night, with slightly drier air moving in for Sat. Another cold front and shortwave trough may touch off isolated showers/storms Sat, but drier air will be a limiting factor. Cooler, drier air will move in behind this front for Sun-Mon. We will see a warming trend into the middle of next week as the remnants of TS Cristobal moving up the MS valley help build an upper ridge over the eastern US. && .AVIATION /00Z THURSDAY THROUGH MONDAY/... A second round of scattered showers and t-storms will develop across parts of the airspace late this afternoon through early tonight. Outside of t-storms, expect mainly VFR conditions to prevail during the 03/012Z TAF period. Some patchy fog is possible in the northern tier late tonight into early Thursday. Outlook... Thu...Showers/t-storms likely especially srn 1/2. Fri-Sat...Chance of showers/t-storms. Sun...VFR/no sig wx. && .CTP WATCHES/WARNINGS/ADVISORIES... None. && SYNOPSIS...Lambert/Evanego NEAR TERM...Lambert/Evanego SHORT TERM...Lambert/Evanego LONG TERM...Gartner/Colbert AVIATION...Gartner
