The Pittsburgh area can expect a mixed bag of weather conditions through the end of the week, with today serving as a brief respite before a series of storms roll in, according to the National Weather Service. Showers and thunderstorms are forecasted to pop in and out of the region from now through Saturday, and there's a marginal chance for some of these to develop into more severe weather episodes. For today, the National Weather Service notes that "convection should be largely suppressed during the day under increased subsidence, but isolated instances are still possible."
Looking further out, things are expected to cool down a bit and resemble something closer to the ordinary, but only after that aforementioned system decides to move on, per the forecast discussion. That slower upper trough should mean periodic precipitation possibilities into the weekend, but temperatures dipping back near normal levels might offer a respite from the recent heat.
For those concerned about the implications for aviation, there's a little good and a little not-so-clear, subsidence will continue to push out the leftover lower-vis clouds early this morning, giving way to mostly scattered clouds later on, driven up by daytime heating and occasional gusty west winds. Uncertainty hangs high as to whether extra storms will develop or slide into the airspace after 18z, and the NWS aviation forecast keeps hourly storm possibilities low while maintaining a general VFR outlook for the time being. The weekend forecast calls for more of the same, with periodic showers and thunderstorms expected to continue disrupting clear skies and visibility.
