Pittsburgh Weather: Strong Winds and Storms Possible Wednesday Afternoon
Pittsburgh weather turns wet Wednesday afternoon, and the strongest impact is expected between 3 p.m. and 5 p.m. Rain and thunderstorms were moving toward the city with lots of lightning, isolated downpours and a risk of strong straight-line winds.
Temperatures were in the 60s Wednesday morning before rain moved in, then were expected to reach the 60s again Wednesday afternoon ahead of a second round of storms. After that push, readings were expected to dip into the 50s.
Pittsburgh forecast window
The forecast pointed to two periods when severe weather could develop, both tied to the leading edge of the rain. Frequent lightning and downpours were possible, and strong straight-line winds were listed as the main severe concern.
As of 4:15 PM EDT on April 29, 2026, the weather pattern was expected to bring rain and thunderstorms into Pittsburgh on Wednesday afternoon. That timing leaves the heaviest weather centered in the middle of the day’s commute and outdoor activity window, not later in the evening.
Thursday through Saturday
Conditions were expected to cool off after the storms. Thursday, Friday and Saturday were projected to stay in the 50s, with lows near 40 degrees each morning in Pittsburgh. Skies were expected to be mostly cloudy, with a low chance of drizzle and northwest mid-level winds.
Pittsburgh was not expected to reach 60 degrees or higher until Sunday at the earliest. For readers planning time outside, the pattern points to a stretch of chilly mornings and only modest afternoon recovery through the end of the week.
Pittsburgh Marathon weekend
The Pittsburgh Marathon is scheduled for the weekend, and the forecast for the races stays close to the same range: highs near 60 and morning temperatures near 40. That gives runners and spectators a cooler setup than Wednesday’s stormy stretch, but still one that calls for layers early in the day.
The weather changes first on Wednesday afternoon, then settles into a cooler pattern through the marathon weekend. Anyone with outdoor plans before then should pay closest attention to the 3 p.m. to 5 p.m. window, when the strongest storms are expected to pass through.
