BANGOR, Maine — People living in northern and central Maine should keep their shovels handy for a little while longer.

The weekend forecast from the National Weather Service called for cold, rainy —and sometimes snowy — weather that started overnight Friday in northern Maine and a mix of rain and snow for points south, including Greater Bangor.

The unsettled weather continued Saturday, with snow in the north and cold rain along the coast.

Between 3 and 6 inches of wet snow were expected in northern Maine, Victor Nouhan, a lead forecaster for the weather service’s Caribou office, said Friday evening.

The St. John Valley and most of the Aroostook River basin were expected to see the most snow, he said.

Snow in mid-April is not out of the ordinary for Maine, Nouhan said.

“Last year, on May 16, we had — it was localized and concentrated in northeastern Maine — 5 to 8 inches, so this is not unusual,” Nouhan said of the late-season snow forecast.

He noted that snow can fall at the top of the state’s tallest mountains as late as June or even in July. Back in the day on top of Mount Katahdin, Caribou saw a trace of snow as late as June 8 in 2000.

A flood warning was also in effect throughout the weekend for the Mattawamkeag River above Mattawamkeag, the weather service said.

Minor flooding was expected to occur on Bancroft Road, between Wytopitlock and Danforth.
