Clouds, a quick warmup, and then a midweek reality check: Pittsburgh is stepping into a stretch of weather that starts mild and ends with a legit severe storm threat, including the risk of damaging winds and isolated tornadoes on Wednesday.
Afternoon Warmth and Brief Morning Showers
Tuesday starts cloudy and around 55°F, with a slight chance of light rain through the mid-morning commute. After that, skies are expected to turn partly sunny as a warmer air mass settles in. Southerly winds will stay on the light to moderate side, so the day should feel noticeably milder than what the city has seen recently.
By afternoon, forecasters expect a high near 73°F, with only isolated, brief showers possible between about 8 a.m. and 1 p.m. Southwest winds should run around 6 to 10 mph. For the latest details, check the National Weather Service forecast for Pittsburgh.
Wednesday’s Severe Weather Window
The real concern arrives on Wednesday, when warm, moist air ahead of a strong cold front sets the stage for more serious weather. That front is expected to trigger widespread rain and thunderstorms from late afternoon into the evening commute. Forecasters say storms could organize enough to produce damaging straight-line winds and isolated tornadoes, with total rainfall of roughly 0.8 to 1.5 inches possible through Thursday morning.

Late-Week Cooler, Windy Turn
Once the front barrels through, temperatures tumble Wednesday night, and rain may briefly flip to snow before ending Thursday morning. In the city itself, little or no accumulation is expected. Northwest winds will ramp up Thursday, with gusts near 30 to 35 mph possible, and another windy system on Friday could bring even stronger gusts in more exposed spots. Expect blustery and noticeably cooler conditions to hang around through the end of the week.
How To Prepare
Keep weather alerts turned on for your phone and plan for possible delays during the Wednesday evening commute. Secure lightweight outdoor items and consider shifting outdoor plans inside. Follow any watches or warnings from the National Weather Service, and give yourself extra time if you need to travel during the Wednesday evening storm window.
