Rain is already making itself at home in Pittsburgh this Tuesday morning, with temperatures sitting around 55°F at the Pittsburgh airport and visibility dropping at times in heavier showers. Forecasters expect showers to hang around until about 11 a.m., then give way to mostly cloudy skies, a breezy south wind, and an unseasonably mild high near 73°F.
Today's Outlook
Early on, look for periods of steady rain with some heavier pockets rolling through before tapering off by mid-morning. The afternoon should be mostly cloudy and drier, even though the overall pattern stays wet and unsettled. New rainfall amounts today should be on the lighter side, generally under a tenth of an inch.
Wednesday Rain And Strong Storm Risk
According to NWS Pittsburgh, a low-pressure system tracking just south of the city will crank up the rain on Wednesday, bringing widespread showers and the heaviest totals of the week. Forecasters are calling for total rainfall between about 0.9 and 1.5 inches, and they warn that several strong to severe thunderstorms could fire up south of the city near Morgantown on Wednesday afternoon into the evening, with damaging wind gusts the main concern.
Timing And Commute
For commuters, that means you should be ready for gusty downpours and slick roads during the morning drive. Plan for extra travel time and take it slow in low-lying spots where water tends to pool. Transit riders might want to check in on PRT Rider Alerts before heading out, since the stronger storms on Wednesday could briefly disrupt service or trigger localized flooding in heavier bands of rain.
Late-Week Chill And Frost Risk
Once the midweek system moves out, the atmosphere flips the script. Cooler air settles in, knocking afternoon highs down into the upper 50s on Thursday and Friday. Morning lows dip into the 30s from Friday through Sunday, bringing a real chance of frost across many neighborhoods north of the city. Gardeners and anyone with vulnerable plants or exposed outdoor pipes will want to cover up or bring things in overnight if possible.
