People in extreme northern Maine on Sunday saw up to a 40-degree shift in temperatures as the mercury climbed above zero for the first time in three days. To the south, meanwhile, a storm swept into the region with as much as a foot of snow for parts of northern New England.

In Allagash, where the temperature hit 39 below, the pipes froze at Two River Lunch, but owner Wade Kelley was looking forward to seeing the thermometer hit single digits.

“Oh, that’s a heat wave. That’s T-shirt weather,” he joked Sunday as workers repaired a burst pipe, caused when a door blew open, letting cold air into the kitchen.

Most of Maine, New Hampshire and Vermont enjoyed warmer temperatures on Saturday, but it took an extra day for the arctic blast of air to recede from northern Maine.

In addition to Allagash’s minus 39, the temperature hit 38 below in Van Buren, 37 below in Fort Kent and 30 below in Caribou, all in northern Maine. By Sunday afternoon, the temperature was climbing to single digits in those areas for the first time since Thursday afternoon.

In Vermont, people awoke to a fresh blanket of snow on Sunday, while a coastal storm was bringing heavy snow Sunday to southern Maine and New Hampshire.

Eight to 12 inches of snow were expected in southern and central Maine and southeastern New Hampshire, said Steve Capriola of the National Weather Service.

In New Hampshire, electronic signs urging drivers to keep speeds below 45 mph were posted along Interstate 93 in hopes of avoiding another major pileup. A week earlier, 59 vehicles crashed on I-93 in Derry during another storm, sending about a dozen people to the hospital.

“Obviously it was a week ago that we had a little issue, so we’re trying to slow things down,” said Department of Transportation spokesman Bill Boynton.

Dozens of cars slid off roads, but there were no major accidents.

A multi-car accident closed part of Interstate 93 in Concord, N.H., and another crash involving about a dozen cars in Londonderry, N.H., had traffic backed up, officials said.

In Maine, several cities including Portland declared parking bans because of the snow.

In Auburn, police handled about 10 accidents throughout the course of Sunday, according to Sgt. James Robicheau. Two accidents that happened on Washington Street ended up blocking the southbound lanes of traffic for a period of time. None of the accidents involved serious injuries.

Robicheau said that one of the biggest snags of Sunday’s winter weather occurred on Poland Road near the town line. Police and crews from Maine Department of Transportation assisted 13 tractor trailer rigs for more than two hours that were trying to make their way up a hill that had not initially been sanded earlier in the day.

Lewiston police, meanwhile, handled six crashes resulting from the weather. None involved any serious injuries.

Both Auburn and Lewiston had winter parking bans in effect for most of the day Sunday and into Monday. While Auburn’s parking ban was scheduled to end at 7 a.m. Monday, Lewiston’s parking ban remains in effect until noon.

In Portland, three finalists for the James J. Fitzpatrick Trophy learned Sunday that they will have to wait longer to learn who will be awarded the honor of being named the top high school football player in Maine because the annual award banquet was postponed because of the snow.
