Slick spots for the mountains and north overnight
Southern areas see showers break out late morning / early afternoon courtesy of low pressure riding along a stalled front offshore. Cold air from the north funnels in this evening, which sets up snow / light mix for the western foothills on up into northern Maine, and rain showers for the coastal plain.
Precipitation ends from west to east in the wee hours of Saturday, ending soon after daylight for the north and east.
Saturday looks mainly dry, breezy, and sunny for the region. The mountains may see some snow shower activity later in the day.
Higher elevations have the better chance for accumulations. Southern and eastern areas may get a snow shower or flurry as the precipitation shield passes through. Unless you are a night owl, you may not even notice it.
A stronger, juicier event Sunday into Monday
A deep area of low pressure works through the Great Lakes into northern Quebec. The associated frontal boundary taps into moisture from Tropical Cyclone Eta. Precipitation breaks out over western and southern areas late Sunday afternoon, and overspreads the state Sunday night.
This could bring a decent soaker for the coastal plain, and may help bring a fair snow base to build on for the slopes.
Precipitation ends from west to east Monday morning. The mountains see the snow machine crank up with off and on snow showers through the middle of the week.
Temperature outlook through Thursday
Where the region has seen well above normal temperatures for the first half of November, Mother Nature appears to balance that off with below normal temperatures beginning Tuesday and continues for a while.
A weak clipper may bring rain / snow showers Tuesday afternoon into the evening for western and southern areas. Another system is possible late next week.
Will there be rain, ice or snow? This graphic explains how having different layers of warm and cold air between the clouds and the ground determines the type of precipitation that hits the ground. nssl.noaa.gov/education/svrwx101/winter/types/
