Pittsburgh is starting Wednesday under mostly cloudy skies near 63 degrees, but the day should brighten and warm up quickly. Mostly sunny conditions are expected through the morning, with temperatures reaching about 81 degrees before a slight chance of showers and thunderstorms arrives after 3 p.m.
The bigger weather concern arrives overnight, when scattered storms could become more widespread and bring brief heavy rain. The National Weather Service in Pittsburgh says saturated ground and storms that repeatedly pass over the same areas could raise the risk of localized flash flooding into Thursday morning.
Overnight Storms Could Bring Heavy Downpours
Wednesday night will turn mostly cloudy, with showers and thunderstorms becoming more likely after 8 p.m. and continuing into the early morning hours. Rainfall totals of roughly a tenth to a quarter-inch are expected, though isolated spots could see more if storms stall or follow the same path.
No flood watch or other weather advisory is posted for Pittsburgh as of Wednesday morning, but residents should keep alerts turned on overnight. Avoid driving through flooded streets or underpasses, especially if heavy rain arrives faster than storm drains can handle it.
Thursday Looks Gray, Foggy And Wet
Thursday will bring a high near 79 degrees, with rain showers likely and patchy fog before 2 p.m. Showers and thunderstorms remain possible later in the day, so morning commuters and anyone with outdoor plans should be ready for reduced visibility, slick roads and periodic downpours.
Friday Brings A Brief Weather Reset
Friday looks like the easiest day of the extended forecast, with mostly sunny skies and a high near 81 degrees. The overnight low should fall to around 63 degrees under partly cloudy skies, offering a quieter break before rain chances return for the weekend.
Weekend Plans May Need A Backup
Saturday will stay warm near 81 degrees, but a slight chance of rain showers develops in the morning before the chance of thunderstorms increases during the afternoon. Saturday night also carries a 50% chance of showers and thunderstorms, while Sunday brings another chance of storms with a high near 78.
The forecast trends drier early next week, with mostly sunny skies and highs around 78 degrees Monday and 80 degrees Tuesday. For now, Friday is the best bet for uninterrupted outdoor plans, while Thursday and the weekend call for a little flexibility.
