NWS Pittsburgh, PA wrote its last area forecast discussion before the first event at Jun 21, 2:27 PM EST, 48 minutes earlier.
Area Forecast Discussion National Weather Service Pittsburgh PA 327 PM EDT TUE JUN 21 2016 .SYNOPSIS... Thunderstorms will be possible this evening south of Interstate 68. The next chance for showers and storms will be Wednesday night through Thursday. && .NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/... Latest surface analysis shows the frontal boundary just south of the PA border where observed dewpoints are still in the upper 60s. Breaks in cloud coverage will allow for increased surface-based instability as the afternoon progresses, with storm development focused along the boundary. Isolated severe storms are possible with a favorable shear environment. Storm potential will diminish by mid-evening as diurnal instability decreases. && .SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/... No significant weather is anticipated through the day as a shortwave ridge transitions over the forecast area. Overnight models have been consistent in showing a complex developing over the midwest earlier in the day and passing through the region after midnight. While low level instability will be minimal, shear aloft will be favorable for organized convection and the depth of the associated cold pool may be deep enough to initiate convectionand maintain the MCS. The primary threat will be damaging winds, but progged PWAT values are progged to be well above the 90th percentile at this time so flash flooding will also be a concern. && .LONG TERM /THURSDAY THROUGH TUESDAY/... The boundary looks to remain over the area after the nocturnal MCS passes to the east on Thursday morning. While its positioning is far from certain due to how quickly it weakens, whether it passes through in a severe fashion, and how much of a mesoscale cold pool it generates and/or leaves behind, the preponderance of model guidance suggests that it should remain over our area into Thursday. This poses significant issues going into the daytime as the upper level wave finally starts to push toward and through the area. In particular, the NAM projects a much better likelihood of periods of clearing behind the MCS early in the day on Thursday. Due to likely heavy rain Wednesday night as well as no real air mass change, the consensus favors dewpoints into the lower 70s across the southern two-thirds of the forecast area on Thursday. In addition, should the clouds break up much at all, temperatures will likely surge well into the 80s. In addition, some mid-level dry air looks to work into the area progressively during the day while 0-6 km shear increases greatly. Helicity values from 0-1 and 0-3 km go off the charts due to hodograph plots that end up looking legitimately like a hockey stick, however their reliability hinges entirely upon the positioning of the boundary. The GFS would suggest farther south positioning of the boundary, as would the new GEM. The forecast was built around a consensus favoring the southern half of the CWA for damaging winds as a result. There certainly would be a possibility of tornadoes as well should the more curved hodographs verify. The front looks to rapidly move south of the area by Thursday evening, ending the threat of thunderstorms and showers. Cooler air and lower dewpoints filter in for a short time thereafter. The cooler conditions will be short-lived, however as amplified ridging builds toward the area for the weekend and early next week. This should again bring heat and humidity back rapidly with temperatures approaching or surpassing 90 degrees by Sunday into Monday. Fries && .AVIATION /19Z TUESDAY THROUGH SUNDAY/... VFR conditions expected through the TAF period with convection moving south of the CWA and shortwave ridging building in overnight. .OUTLOOK /WEDNESDAY THROUGH SUNDAY/... Restrictions are likely early Wednesday night and early Thursday with crossing low pressure. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...None. OH...None. PA...None. WV...None. &&
