Clear skies and calm weather are setting the tone for Maine this week, but residents in the north should be ready for some chilly nights. Patchy frost could develop in valleys, especially in areas like Fort Kent, Presque Isle, and Houlton.
While days will be sunny and pleasant, nights will dip into colder temperatures, making it important to protect sensitive plants.
Sunny Skies with Breezy Afternoons
Across much of Maine, the days will stay mostly sunny and dry. Winds could pick up in the afternoon, gusting up to 25 mph, particularly in northern and central regions. However, conditions are expected to settle down by evening.
Frost Concerns in Northern Valleys
According to the National Weather Service in Caribou, overnight lows are expected to fall into the 30s across Aroostook County and surrounding valleys. This means sensitive plants could get damaged by frost. Residents are advised to cover outdoor plants or bring them inside during the night.
Frost risk: Highest in Fort Kent, Presque Isle, and Houlton
Milder nights: Bangor, Ellsworth, and Bar Harbor, with lows in the 40s to near 50
Daytime Temperatures Stay Comfortable
Despite the cold nights, daytime highs will remain pleasant. Northern parts of the state will see temperatures in the mid-60s, while southern areas will warm into the low 70s. This mix of sunny days and cool nights will continue into midweek.
Chance of Showers Later in the Week
Dry weather will dominate through Wednesday, but Thursday brings a small chance of rain showers in the Crown of Maine. By Friday, sunshine returns, keeping conditions mostly clear and pleasant.
