Thursday, March 26, is starting deceptively calm in Pittsburgh, with clear skies and temperatures around 55°F at 5:40 a.m. EDT. By this afternoon, readings should jump into the low 70s. After that, the atmosphere flips the switch, with a strong cold front sweeping in and turning a mild day into a noisy, stormy night. Expect scattered showers to develop later today, followed by a higher chance of thunderstorms, sudden downpours, and gusty winds from evening into the overnight hours.
Evening and Overnight Threats
According to the National Weather Service, showers and thunderstorms are expected to fire along a slow-moving cold front Thursday evening and continue into the overnight hours of March 26–27. Some of these storms could dump heavy rain in a short time. New rainfall totals between 1 and 2 inches are possible in spots, especially along and near the I‑70 corridor north toward Route 422, where streams and small creeks could rise quickly.
As of early Thursday’s forecast discussion, no watches or warnings were in effect. Forecasters noted, however, that a flash-flood watch may be needed if heavier bands set up and persist over the same locations.
Severe Storm Risk
The Storm Prediction Center has placed parts of eastern Ohio in an Enhanced Risk, with a Slight Risk extending into western Pennsylvania. Translation: at least some of the storms crossing the area late Thursday could become severe.
Damaging wind gusts are the main concern, but a few storms could also produce large hail or an isolated tornado in the strongest cells. That risk will peak in the evening as a line of storms pushes southeast across the region.
What to Expect for Your Commute
Brief, heavy downpours may quickly soak roads and cut visibility during the evening drive. Low-lying areas can see standing water in a hurry, which is not great news for those last-minute grocery runs.
Southwest winds this afternoon will gust into the mid-20s, then swing around to the northwest tonight with gusts still around 25 to 30 mph behind the front. Plan on extra travel time, steer clear of flooded streets, and be ready for possible delays on buses and light rail if tree branches, debris, or power issues pop up.
Weekend Outlook
Behind the front, Friday turns cooler and unsettled, with rain likely and a high near 52. Friday night gets much colder, with lows dropping into the mid-20s in some locations. The payoff arrives Saturday, when sunnier and quieter weather returns with highs near 46, followed by a warmer trend into Sunday with temperatures around 60. For the latest timing and any new watches or warnings, check the National Weather Service.
If severe thunderstorm warnings are issued, head indoors to an interior room away from windows, and never try to drive through flooded roadways, no matter how shallow they look. Keep wireless alerts enabled on your phone, have a battery-powered radio handy, and monitor updates from the National Weather Service and the Storm Prediction Center as the storms move through.
