Caribou, ME – Northern Maine remains locked in an unseasonably cool pattern today, with plentiful sunshine doing little to push temperatures toward typical spring levels. While the skies will stay clear through the afternoon, a significant chill persists, and you’ll want to keep the winter layers handy for any outdoor activity today. The stability of the current dry air won’t last long, as clouds are already projected to gather by late Wednesday morning.
According to the National Weather Service in Caribou, Tuesday night will bring a hard freeze to much of the region, with lows plunging to 19 degrees in Estcourt and the low 20s across the Crown of Maine. While there are no major storms on the immediate horizon, this prolonged cold snap is keeping soil temperatures low and delaying seasonal growth. A weak system is timed to arrive Wednesday night, introducing a 30% chance of light showers that could linger through Thursday afternoon.
Commuters on I-95 and Route 1 should expect dry conditions today, though the overnight freeze may create isolated frost patches on bridges by Wednesday morning. Highs today will struggle to clear the mid-40s, with Caribou peaking at 42 degrees and Bangor reaching 46. The air remains dry enough that visibility will be excellent, though the wind chill will make it feel notably colder during the morning and evening hours.
The unseasonably cool air finally begins to erode by the weekend as a ridge of warmer air pushes into New England. Thursday will see highs stay in the upper 40s under overcast skies, but a noticeable warming trend is locked in for Saturday. We will update the timing of the Wednesday night showers if the system accelerates, but for now, expect a dry but frigid Tuesday night across the entire northern tier.
