Clear skies and mild air to start Tuesday are not sticking around for long in Pittsburgh. It is about 59°F at dawn, with highs headed for the upper 70s later on Tuesday, May 5, 2026. By this afternoon, though, southwest winds will crank up and a cold front will slide in, bringing a shot at showers and thunderstorms late tonight into Wednesday.
Afternoon Winds Pick Up
Meteorologists at the National Weather Service Pittsburgh expect southwest winds to strengthen after sunrise, with sustained speeds in the teens and gusts often in the mid-30 mph range. The higher ridges and more exposed spots could briefly see 40 to 45 mph gusts, strong enough to toss around lawn chairs and trash can lids, but still below Wind Advisory criteria. It is a good day to tie down patio furniture and use extra caution on bridges and elevated ramps during the afternoon drive.
Rain Moves In Tonight
Showers and a few thunderstorms are most likely to fire up late Tuesday evening, generally after about 8 to 11 p.m. on Tuesday, May 5, 2026, then become more widespread overnight into Wednesday. Most neighborhoods will pick up only a few tenths of an inch of rain, with a few heavier cells pushing totals toward a half inch. Conditions should start to improve sometime Wednesday afternoon, although occasional showers may hang around into the weekend as the unsettled pattern lingers.
Impacts For Riders And Travelers
Gusty crosswinds and damp pavement could slow the evening commute and lead to scattered delays, and low clouds combined with steady rain overnight may cut visibility for early drivers on Wednesday. Air travelers should keep an eye on airline alerts for potential schedule changes, and bus and light rail riders are encouraged to check for updates from Pittsburgh Regional Transit before heading out. If you are driving, allow some extra time and watch for ponding in low-lying streets and on highway ramps.
How To Prepare
Grab a waterproof layer if you have evening plans, and lock down or bring in outdoor furniture and garbage cans before the strongest afternoon gusts arrive. Try not to park under large trees during the evening in case of loose limbs, and keep a flashlight handy in the event of brief power flickers. Looking ahead, if the skies clear later in the week, there is a chance for frost Thursday night, so be ready to cover up any tender plants you are worried about.
