Caribou, Maine – The first true chill of September will hit Northern New England late Monday night, with widespread frost advisories issued from Maine to the Adirondacks. Temperatures are expected to dip into the low to mid-30s, raising concerns for gardens, farms, and sensitive plants.
According to the National Weather Service, advisories are in place from 11 p.m. Monday until 8 a.m. Tuesday across northern Maine, including Aroostook, Penobscot, Piscataquis, and Somerset counties. Similar alerts stretch into northern New Hampshire, Vermont’s Northeast Kingdom, and parts of upstate New York, including Lewis, Hamilton, and Oneida counties.
Cold air pooling in valleys and sheltered areas could bring patchy frost to towns like Caribou, Houlton, Millinocket, Berlin, Colebrook, Lake Placid, and Saranac Lake. Gardeners are urged to cover plants or bring them indoors, as even a brief frost can damage late-season crops and flowers.
Travelers in the higher elevations of the Adirondacks and White Mountains should also prepare for brisk early morning conditions, with temperatures hovering close to freezing.
Advisories remain in effect until 8 a.m. Tuesday, with forecasters noting additional frost risks later this week if clear skies and calm winds persist.
