Caribou, Maine – Sunshine is lighting up northern Maine this Monday morning, but the quiet weather won’t stick around for long. Dry roads and crisp air are making for an easy start across Aroostook County, yet a much wetter pattern is lining up over the next 48 hours. If you have outdoor work or travel plans, today offers the best window before rain spreads into the region.
According to the National Weather Service, Monday remains sunny with a high near 72 degrees. West winds between 9 and 13 mph will occasionally gust to 24 mph, keeping the afternoon comfortable despite plentiful sunshine.
Travel conditions remain favorable today along U.S. Route 1, U.S. Route 2 and Route 89, but drivers should prepare for changing conditions beginning Tuesday night. Clouds increase Tuesday as temperatures climb to 79 degrees, making it the warmest day of the week before a widespread rain event develops.
Rain becomes likely after 2 a.m. Tuesday night, with an 80% chance of precipitation. Forecasters expect between one-quarter and one-half inch of rainfall, with locally higher amounts possible in heavier showers. Wet pavement and reduced visibility could affect the Wednesday morning commute across northern Maine.
Wednesday stays unsettled with periods of rain before showers and a possible afternoon thunderstorm. High temperatures cool into the mid-70s while southwest winds continue to gust above 20 mph. Although severe weather is not expected, an isolated rumble of thunder and brief heavier downpours could create localized ponding on roads. An isolated tornado cannot be completely ruled out with any thunderstorm environment, but the overall risk remains very low.
Conditions steadily improve Thursday as sunshine returns and highs reach the middle 70s. By Friday, bright skies and temperatures near 80 degrees signal another pleasant stretch across northern Maine.
Looking farther ahead, the 6-to-10-day outlook favors above-normal temperatures across much of the Northeast, suggesting warmer-than-average conditions could return later next week.
