Bangor, Maine – Hot, muggy weather is ramping up across Maine, with scattered thunderstorms expected to disrupt northern and western communities from midday Monday through late afternoon. Drivers and outdoor workers in Bangor, Caribou, and surrounding towns should be alert for sudden downpours and lightning.
According to the National Weather Service in Caribou, low clouds will linger across much of the state Monday morning before giving way to brief breaks of sunshine. Thunderstorms may develop from the low 70s Downeast to the low 80s in northern Maine, especially along U.S. Route 1 and I-95 corridors.
Heat and humidity will intensify Tuesday and Wednesday, with interior southern spots—like Augusta and Lewiston—likely hitting 90°F by late Tuesday and climbing into the low 90s Wednesday. Residents should limit strenuous outdoor activity, drink extra water, and never leave pets or children in vehicles.
Widespread showers and more thunderstorms are expected Thursday as a frontal system sweeps in, bringing the greatest risk to northern and western counties. Power outages and minor flooding are possible in heavier storms.
Stay tuned for new warnings as conditions may change quickly through Wednesday, with further updates as the next storm system arrives.
