Pittsburgh starts Monday in the low 50s under clear skies, then warms to a sunny high near 67 degrees. Northwest winds will build through the afternoon, making it a classic jacket-and-sunglasses kind of day, with no rain expected.
The bigger weather turn arrives Monday night, when temperatures drop sharply under mostly clear skies. The National Weather Service issued a Frost Advisory from midnight Monday through 9 a.m. Tuesday for higher elevations and northeastern counties, where temperatures could fall as low as 35 degrees and damage sensitive plants; the advisory is a notable update from Sunday’s outlook.
Afternoon Winds Pick Up
Monday’s sunshine will be accompanied by northwest winds of 5 to 14 mph, with the strongest breeze arriving around midday and early afternoon. Temperatures should peak near 66 or 67 degrees before easing through the evening.
Cold Start Tuesday, Warmer Midweek
Tuesday will stay sunny but begin with a chilly low around 41 degrees before reaching about 65 in the afternoon. The warmup arrives quickly, with highs near 73 Wednesday and around 72 Thursday and Friday.
Dry Weather Holds Through Saturday
Saturday looks mostly sunny with a high near 72, keeping the region dry and comfortable for outdoor plans. Sunday could reach 74 degrees under partly sunny skies, though the forecast includes a small chance of rain, and the next broader opportunity for showers may come Sunday into Monday.
