PITTSBURGH, Pennsylvania — Tuesday afternoon, September 22, 2026, is going to feel like fall arrived overnight across Pennsylvania, Maryland, Virginia and West Virginia, with temperatures dropping into the 50s and 60s across the region and northeast winds gusting 15 to 25 MPH making it feel even cooler.

Northeast Winds Gusting 15 to 25 MPH Make It Feel Even Cooler
Beyond the temperature drop, northeast winds gusting 15 to 25 MPH will make Tuesday afternoon, September 22, 2026 feel noticeably cooler than the thermometer already indicates. Northeast winds are classic fall winds across the Mid-Atlantic and Pennsylvania, funneling cool air southward from Canada through the region. When 15 to 25 MPH gusts combine with temperatures in the 55 to 65 degree range, wind chill values can push the feels-like temperature several degrees below the actual reading. Anyone heading outside for the Autumnal Equinox on Tuesday should bring a light jacket — the days of needing to carry water just to walk to the car are firmly in the rearview mirror for Pennsylvania, Maryland, Virginia and West Virginia after Tuesday.
The Nor’easter Buzzing Online Is a Separate and Later Story
The source data addresses the Nor’easter discussion circulating online and makes an important clarification — the cool and breezy conditions arriving Tuesday, September 22 are not related to the Nor’easter being discussed online. That is a separate storm potentially forming farther off the coast at the end of next weekend, which would be the September 26 through September 27, 2026 window previously identified. Forecasters advise against jumping into dire forecasts for that storm this far out, noting that what circulates online often relates to model solutions that can be overblown at long range. A full week remains for that pattern to take shape and be properly assessed.
