Caribou, ME – Halloween celebrations across northern and eastern Maine will face a significant temperature change this weekend, with mild conditions in the lower 60s Thursday giving way to chilly Saturday evening temperatures that could fall into the 20s in some communities.
According to the National Weather Service in Caribou, an extended period of mainly dry weather will continue across the region, with a weak cold front bringing a few showers late Thursday night into Friday before colder conditions settle in for Halloween.

Friday temperatures will range from 50 to 56 degrees across northern Maine, while southern portions of the forecast area could reach 60 to 65 degrees.
West to northwest winds of 10 to 15 mph, with gusts up to 30 mph, are also possible Friday.
Halloween Night Could Turn Very Cold
