Portland, ME — Sudden snow squalls could create dangerous travel conditions across Maine, including the Portland area, Thursday and Friday.
According to the National Weather Service Weather Prediction Center, scattered snow squalls are expected to develop across the Northeast behind a strong cold front on Thursday, with another round possible on Friday. Maine is included in the snow squall risk area, where brief but intense snowfall and gusty winds may rapidly reduce visibility.
Forecasters said snow squalls may move into western and central Maine Thursday before shifting eastward toward the coast, including the Portland metro area. A second round is expected Friday afternoon as the system progresses west to east across New England. Not all locations will be impacted, but any squall that forms could quickly make road conditions hazardous.
Snow squalls are particularly dangerous because they can cause near-zero visibility within minutes, even when roads were previously dry or just wet. Road surfaces can become snow-covered quickly, increasing the risk of crashes on highways, bridges, and coastal roadways. The Weather Prediction Center emphasized that these rapid changes can catch drivers off guard.
Travel impacts are most likely along major routes such as I-95, I-295, and U.S. Route 1, especially during daytime travel periods. Commuters, students, and young workers traveling during peak drive times may be especially vulnerable if a squall coincides with heavier traffic.
The National Weather Service advises drivers who encounter a snow squall to slow down immediately, turn on headlights and hazard lights, and avoid slamming on the brakes. If visibility becomes too poor, motorists should safely exit the roadway when possible and wait for conditions to improve.
Residents and travelers across Maine are urged to monitor local forecasts and real-time road conditions through Friday, as snow squalls can develop with little warning and timing may shift.
