If you’re in northern or eastern Maine, it’s time to keep your umbrella close. After a calm and cool start to the week, rain chances are on the rise as we head into the weekend. From patchy fog to widespread rain, the next few days will bring changing weather conditions across Caribou, Presque Isle, Houlton, and other towns in Aroostook County.
Patchy Fog and Cool Nights to Start the Week
Tonight will stay mostly clear and dry, but a dip in overnight temperatures will lead to the formation of patchy fog across low-lying areas. Interior regions like Presque Isle and Caribou can expect lows around 50°F, making it a cool and crisp evening.
Fog Safety Tips:
Use low-beam headlights when driving
Slow down and allow extra time on rural roads
Watch for sudden visibility drops near open fields or forests
Midweek Showers on Wednesday
By Wednesday afternoon, scattered showers are expected to return across much of Aroostook County. While not a washout, these brief rain spells may interrupt outdoor plans, especially in towns like Houlton and Fort Kent.
Wednesday highlights:
Highs around 68°F
Spotty showers in the afternoon
Patchy fog possible in the early morning
Make sure to carry a light rain jacket or umbrella, especially if you’ll be outdoors during the late afternoon.
Thursday: A Brief Break in the Clouds
Thursday will offer a short break from the rain, with sunny skies expected in the morning before clouds increase by the evening. It’s the best day of the week for any outdoor activities or errands.
Forecast for Thursday:
Highs near 70°F
Mostly sunny morning
Clouds moving in late afternoon or evening
Take advantage of this brief dry window before conditions turn wetter again.
Weekend Rain Chances Increase Across the Region
Starting Friday, a low-pressure system will track into New England, spreading rain showers throughout northern and eastern Maine. The heaviest rainfall is expected Saturday, with cooler temperatures and multiple rounds of wet weather continuing through Sunday.
Areas from Bangor up to Frenchville may experience:
Consistent rain on Saturday
Cooler highs in the low to mid-60s
