The spring-like temperatures early this week had many Mainers breaking out their sneakers, but it’s back to boots this weekend.

All of Maine is expected to see at least some snow Friday night into Saturday, forecasters say, though how much varies widely.

An incoming clipper system is expected to bring about 1 to 2 inches to Cumberland and York counties, while 2 to 3 inches is expected in the Lewiston-Auburn area; 3 to 4 inches in the Augusta region; and 4 to 6 inches from Skowhegan to Calais, according to a Thursday afternoon forecast from the National Weather Service offices in Gray and Caribou.

Much of northern Maine can expect 4 to 6 inches of snow Friday into Saturday, but southern Aroostook County and northern Penobscot County could see up to 8 inches, according to the weather service. Due to its elevation, Katahdin could get up to a foot.

A stronger system is expected to reach the Northeast late Sunday and linger into Monday night, according to the weather service.

Hunter Tubbs, a meteorologist at the weather service’s office in Gray, said the precipitation may begin as snow in southern Maine, but temperatures are expected to climb into the 40s and 50s by Monday, turning it into “clean rain.”

“The rainfall doesn’t look to be terribly heavy, but there is the potential for an inch or so of rain in some places,” Tubbs said in a phone interview Thursday afternoon.

Gusty winds are also expected in that storm.

According to the weather service’s Caribou office, most of the state will likely see wind gusts of over 40 miles per hour Monday. That included a 63% chance in Portland, 67% chance in Augusta and 69% chance in Bangor, according to a Thursday afternoon forecast.

The warm temperatures and rainfall are expected to spur snowmelt and the weather service warned of potential ice jams along rivers and streams going forward.

Ice is already beginning to break on rivers, Tubbs said, making ice jams possible yet “very unpredictable.”

“If one does form, there’s potential for water to rise above the riverbank behind it,” the meteorologist explained. “If the jam were to give out suddenly, there could be a sudden rush of water downstream.”

However, the weather service said Thursday that the overall flood risk was still considered low.

“We’re still in drought conditions, believe it or not,” Tubbs said. “River levels are quite low, so there’s still a bit of room for them to rise before they would actually cause flooding.”

Tubbs encouraged members of the public to alert the weather service to any ice jams they come across.

“That information is tracked here at our office so we can keep an extra eye on it, see if there are any potential issues,” he said.
