Pittsburgh woke Wednesday, September 2, to fog, muggy air, and temperatures around 73 degrees, but the day is headed toward a 93-degree high. A Heat Advisory is in effect as the heat index could reach 102, with the biggest storm concerns shifting into late Wednesday and Thursday.
The National Weather Service says the advisory runs from 8 a.m. Wednesday through 8 p.m. Thursday across Pittsburgh and much of western Pennsylvania. That is a notable update from Tuesday’s forecast, when the storm threat was still described more generally in Hoodline coverage.
Heat Peaks Wednesday And Lingers Thursday
After a small chance of early showers or thunderstorms, skies should turn mostly sunny Wednesday, with southwest winds of 2 to 8 mph. Thursday stays hot, topping out near 92 degrees with heat index values near 102, so hydration, shade, and air conditioning are the safer bets during the afternoon.
Late-Day Storms Could Disrupt Plans
Storm chances rise again Wednesday night, especially from late evening into the overnight hours, and Thursday carries a 50% chance of showers and thunderstorms. The weather service says some storms could be severe, with gusty winds, hail and a small tornado risk possible, so outdoor plans should have a backup.
Friday looks wetter, with showers and thunderstorms likely and an 80% chance of precipitation, although temperatures ease to about 86 degrees. The pattern finally breaks for the weekend: Saturday should reach 82 with only a slight shower chance, followed by sunny 80-degree weather Sunday and mostly sunny skies around 82 on Labor Day.
What Pittsburghers Should Do
The advisory calls for drinking plenty of fluids, taking breaks from the sun, and checking on relatives and neighbors who may be more vulnerable to heat illness. If thunder roars, head indoors and wait for the storm to pass; the more comfortable forecast arrives Saturday.
