Polar vortex brings chilly temps to Maine

PORTLAND PRESS HERALD • January 5, 2025

The eastern U.S. is on track for a frigid week as a polar vortex stretches south, bringing below-normal temperatures to Maine. Starting Monday, much of the eastern two-thirds of the country will see temperatures 12 to 25 degrees colder than usual for this time of year. In Portland, temperatures were only expected to be about 6 degrees below normal Sunday and Monday, said Jon Palmer, a meteorologist with the National Weather Service in Gray. The interior parts of Maine will see the chilliest conditions, with lows in the single digits and below zero in some spots.
