Northern Maine residents can look forward to a pleasant stretch of warm, sunny weather through midweek, with daytime temperatures rising into the mid to upper 70s. But early risers and commuters should be mindful of patchy morning fog, especially in low-lying areas near rivers and valleys.
Foggy Mornings and Sunny Afternoons
The National Weather Service in Caribou has issued a weather advisory noting fog development each morning, mainly from Presque Isle to Fort Kent. While it’s not expected to be dense or long-lasting, this fog could briefly reduce visibility along rural roads, particularly around daybreak.
Here’s what to expect from now through Thursday:
Patchy fog early in the morning
Mostly sunny skies by late morning
Daytime highs in the mid to upper 70s
Light winds, making for very comfortable outdoor conditions
This calm and dry pattern makes it a great time for outdoor activities like hiking, biking, or even a short trip to one of Maine’s scenic spots.
Cooler Weather Ahead Starting Friday
A cold front is expected to move into the region late Thursday into Friday, bringing:
A slight chance of showers, mostly in northern Aroostook County
Scattered, light rainfall if any develops — nothing significant
Increasing winds by Friday afternoon
A cooler air mass that will bring down temperatures over the weekend
While Friday might still start off mild, by the afternoon you’ll likely feel the shift, especially as breezier conditions set in.
Weekend and Next Week Forecast
Looking ahead to the weekend:
Expect noticeably cooler temperatures
Dry conditions will likely continue
Winds may remain steady, so jackets might come in handy, especially in the mornings and evenings
No major weather systems are expected early next week, but residents should stay tuned for updates, especially if cooler temperatures deepen or stronger winds develop.
Northern Maine’s mid-September weather is shaping up to be calm and pleasant, with just a few morning fog patches to watch for. Daytime warmth will continue until a cold front brings slight rain chances and cooler air by Friday. Whether you’re commuting, farming, or just enjoying the outdoors, this is a good week to take advantage of the sunshine before the fall chill sets in.
