Caribou, Maine – Light snow will redevelop across far northern Maine late Wednesday night, creating slick stretches along US-1 and Route 11 before the Thursday morning commute.
According to the National Weather Service in Caribou, a cold front sliding south will trigger a period of light snow mainly north of the Katahdin region, including the Saint John Valley. Snowfall totals are expected to remain around 1 inch or less, but even minor accumulation could create slippery conditions on untreated roads by 6 a.m. Thursday.
Communities including Caribou, Presque Isle, Fort Kent and Madawaska are most likely to see the overnight snow. Farther south toward Bangor and Downeast Maine, skies will clear earlier Wednesday with improving travel conditions through the afternoon before colder air arrives overnight.
Temperatures will fall sharply behind the front, dropping into the single digits north and teens Downeast by daybreak Thursday. Any moisture left on pavement could refreeze, increasing the risk of black ice on I-95 near Houlton and secondary highways across Aroostook County.
Drivers should reduce speed on bridges and overpasses, where surfaces freeze first, and allow extra stopping distance during the Thursday morning commute. Residents are encouraged to check heating systems and dress in layers as much colder air settles in for the day Thursday, with highs only reaching the teens north and lower 20s near Bangor.
Conditions turn milder again heading into the weekend, though another system could bring a wintry mix changing to rain by Saturday. Additional advisories may be issued if overnight snowfall becomes steadier than expected.
