Today, Pittsburgh is waking up warm, wet and a little on edge, with mostly cloudy skies and muggy air hanging over the city. Temperatures are sitting near 66°F at Allegheny County Airport, and the ground is still slow to dry after Tuesday's storms. Those downpours dumped heavy rain in pockets and kept some neighborhoods dealing with high water well into the night. Downtown looks likely to dodge any major flooding for now, but low-lying streets and small streams could still see some nuisance rises through the morning commute.
Rivers And Flooding
Forecasters say the bullseye for rain totals landed south of the city, where about 2 to 4 inches fell. That was enough for "high-water impacts" to stick around into early Wednesday. According to the National Weather Service in Pittsburgh, the Allegheny and Youghiogheny basins took the brunt of the soaking. The agency currently rates the chance of flooding at the Mon Wharf parking lot in downtown Pittsburgh as low. Still, anyone with riverfront plans or a car parked near the water is being urged to double check conditions before heading out and, as always, skip the temptation to drive through standing water.
What To Expect Today
Clouds should gradually give way to some sun by midday, with highs topping out near 76°F and a northwest breeze around 7 to 10 mph helping things feel a bit fresher. There is a slight chance for a few lingering, spotty showers early on, but most of the day is expected to stay dry and noticeably more comfortable as the air mass continues to dry out. Tonight turns cooler and clearer, with lows dipping into the mid-50s.
Looking Ahead
High pressure builds in and should keep conditions dry from Wednesday afternoon through Friday, with a slow warmup sending daytime highs into the upper 70s and low 80s. The National Weather Service in Pittsburgh is already flagging the next potential troublemaker, cautioning that severe thunderstorms could return as early as Sunday. Machine-learning guidance currently puts the probability of severe storms across the Ohio River Valley between 5 and 30 percent from Sunday through Tuesday, with any stronger storms capable of producing damaging winds, large hail and another round of heavy rainfall.
