Pittsburgh woke up in a sweatbox Sunday, with fog and muggy air draped over the city, mist at the airport and temperatures sitting around 66°F as humidity hovered near 94%. Creeks northeast of town are still running high after several inches of overnight rain, but the gloom is expected to break for a milder, partly sunny afternoon with highs near 82°F.
Morning Conditions And Flood Notices
Flood Warnings stayed in place early Sunday for spots northeast of Pittsburgh, where small streams, including Red Bank Creek near St. Charles, were still elevated after 3 to 4 inches of rain. Some local roads may remain closed until the water drops, according to the National Weather Service Pittsburgh. Anyone living in or driving through low-lying neighborhoods should check local road updates before heading out and steer clear of standing water.
Afternoon And Tonight
By this afternoon, conditions should improve to partly to mostly sunny skies with a high around 82°F and a northwest breeze near 7 mph. Tonight is expected to be mostly clear with a low near 58°F, and Monday is set to turn warmer and sunnier with highs near 84°F. That gives residents a relatively calm window for outdoor plans before the next weather system lines up.
Severe Storms Possible Tuesday, July 21, 2026
A stronger storm system is forecast to arrive Tuesday, July 21, bringing an elevated severe weather threat for the region. Local forecasters highlight an Enhanced Risk for that day, with the potential for damaging wind gusts, isolated tornadoes and heavy, training downpours that could trigger flash flooding. Brief rainfall amounts of one half to three quarters of an inch are possible, with higher totals where storms repeatedly track over the same neighborhoods.
How To Prepare
Residents are urged to move vehicles out of low-lying driveways, secure loose outdoor items Monday night and keep phones charged for any watches and warnings.
