A cold front swings through New England on Wednesday ahead of another winter storm. Mostly cloudy skies are on tap, with highs ranging from the low 40s south to the mid 30s across the north.
This storm will bring mostly rain for the Boston metro area, a mix of rain and snow to central areas and mainly snow across New Hampshire and Maine. The heaviest snowfall is expected around Conway, New Hampshire and Fryeburg and Bridgton, Maine. Portland could see another 6 to 8 inches after receiving 31 inches in a seven-day stretch.
The onset of precipitation may fall as rain across coastal New Hampshire and southern Maine on wednesday afternoon before flipping over to all snow by Wednesday evening. Cold air wrapping around the back side of the storm will aid in switching rain over to snow across southern and eastern New England later Wednesday night.
Not expecting much in the way of the snow accumulation in Boston - only about 1 to 2 inches. A concentrated band of precipitation, also known as an inverted trough (or Norlun trough), will develop across southeast Maine and northern New Hampshire on Wednesday afternoon, focusing a band of snow over these areas. Snowfall rates may reach 1 to 2 inches per hour.
We’re forecasting this band to swing into northeastern Massachusetts around midnight. Half a foot to a foot of snow will fall across the northern mountains, with a foot to 18 inches across the higher mountain ranges of the White Mountains into western Maine.
Winds will increase Wednesday night in response to deepening low pressure east of Cape Ann in the Gulf of Maine, becoming sustained from 15 to 20 miles per hour across the region, gusting to near 40 mph at times across the Cape and Islands.
Two to four inches of snow may accumulate across the Green Mountains and the east slopes of the Berkshires as cold air interacts with the terrain and remaining moisture across the region.
Snow lingers into Thursday across New Hampshire and Maine, while the rest of New England dries out, with gusty winds whipping from the northwest. Wind chills in the teens and twenties will make it feel brisk outside.
