PORTLAND, Maine — The state’s largest city and the most northern city in the state both saw record-high temperatures Monday, meteorologist Margaret Curtis of the National Weather Service office in Gray said Monday evening.

Portland reached a high of 59 degrees, surpassing its previous record for the date of 53 by noontime, meteorologist Tom Hawley said shortly afterward. Caribou’s new record high of 52 was set Monday afternoon, Curtis said.

Caribou’s previous record was 51.

Bangor’s record high is 63 degrees and it was 51 around 1:30 p.m. Houlton’s record is 58 degrees, Hawley said.

No records were broken in Houlton, but it was warm for northern Maine.

“It got up to 51,” Curtis said of Houlton.

The high temperatures are going to change drastically later this week when a wave of brutally cold weather is expected to hit Vacationland.

“An arctic cold front will cross the region on Thursday bringing below-normal temperatures for Friday,” the weather service website states. “A warm front will attempt to work into the region Friday night and Saturday, with another arctic cold front dropping into the area Sunday.”
