Pittsburgh is waking Tuesday to fog and damp air, with temperatures near 66 degrees before another round of showers and thunderstorms moves through the region. The city should climb to about 83 degrees, but the bigger story is the risk of repeated downpours from late afternoon into the evening.
A few showers and storms could linger before 7 a.m., followed by patchy fog and a greater chance of rain and thunderstorms later in the day. The National Weather Service's Pittsburgh office puts the Tuesday rain chance at 70%, with a quarter- to half-inch of rain possible, though heavier pockets could produce more.
Tuesday Storms Could Bring Heavy Downpours
Hourly forecasts show storm chances rising through the afternoon, reaching roughly 40% to 50% between 2 and 5 p.m. and 70% by 5 p.m. Storms are expected to continue into Tuesday night, when the rain chance rises to 80%, and another half-inch to three-quarters of an inch could fall.
The National Weather Service warned that thunderstorms could train over the same areas, creating localized flash-flooding concerns and bands of 2 to 3 inches of rain in an hour or two. As of early Tuesday, the formal Flood Watch cited by the forecast office did not include Pittsburgh proper, but forecasters said additional expansion remained possible.
Storm Chances Hang Around Through Thursday
Wednesday will bring a high near 84 with a chance of morning showers and a slight chance of afternoon storms. Thursday looks similarly warm, with another high around 84 and scattered showers or thunderstorms possible, while Friday begins a brief drier stretch with mostly sunny skies and a high near 82.
Cooler Nights Arrive Before Another Stormy Weekend
Friday night could dip to 59 degrees, the coolest night in the outlook, before Saturday returns to mostly sunny conditions and a high near 81. Storm chances rise again Sunday, when showers and thunderstorms are likely with a high around 84, followed by another unsettled Monday.
For Tuesday, drivers should be prepared for fog early, sudden visibility drops in downpours and ponding on roads where storms repeatedly pass. Anyone hearing thunder should head indoors, while residents in flood-prone areas may want to monitor alerts as the storm pattern continues.
