Brace yourselves, Pittsburgh. A dash of showers and the occasional crackle of thunderstorms are on today's weather menu, accompanied by blustery winds that could rattle the windows, mainly for those residing south of Interstate 80. The National Weather Service Pittsburgh, PA, has updated its forecast, signaling a much cooler week ahead, marred by a persistent trough of low pressure, before conditions eventually mellow out by the weekend.
We're tracking a surface low pressure across the board—particularly IN, to be precise—with its warm front stretching through NW PA. According to the National Weather Service, this system is predicted to meander eastward throughout the day, trailing the front northward and ushering in scattered showers, especially north of I-80. "Mixing in the warm sector, and the low-level jet, should result in gusty wind developing by mid to late morning," the service notes, with special attention pointed towards those south of the I-70 and in the ridges, where gusts might push boundaries up to 40 mph. Still, confidence in meeting advisory criteria remains low, per the weather outlook.
As for the temperatures, expect a slight uptick with highs boosted across most regions, courtesy of being cozied up in the warm sector and a rather sparse dance of precipitation. The coattails of a cold front will sweep through by afternoon, dialing down showers and ruling out any significant chance of severe storms, given limited instability and moisture. Skies should be dry for the remainder of the TAF period post-trough crossing, as the updated aviation forecast outlines. There may be a smattering of rain showers and an outside shot of a thunderstorm along the frontline, but those are low-odds bets.
Fast forward to the evening and the onset of the short term: It's a familiar autumn tale—cooler days heralded by a medley of scattered showers through Tuesday night. "After a lull in the precipitation after FROPA," the National Weather Service illustrates, "additional scattered showers are expected to develop as this trough approaches." The gusty wind continues its symphony tonight, albeit at a less boisterous tempo than Sunday's daytime performance. And while this cold-air concerto plays, temperatures have a solo that features notes well below seasonable levels.
