Snow from this morning’s Alberta Clipper will continue to wind down from west to east through the early afternoon hours. Most will be just about done with the snow by midday, but Maine will naturally be in it a bit longer being the farthest east. The big question this afternoon will be cloud cover. Typically, systems that see a westerly flow post-storm see rapid clearing, however, a temperature inversion may trap moisture in the low-levels, causing a slower than usual clearing. The afternoon may be stubbornly cloudy if this inversion holds.

After this clipper moves through the region, high pressure will take over for the remainder of the week, leading to calm and mostly dry conditions for New England. The only real precipitation chance will be some ocean-effect snow/rain showers across southeast Massachusetts on Christmas Day. Christmas itself will be a quiet, calm and seasonable day with variable clouds. For many, the day may have just the right amount of chill in the air without escalating to a biting or bitter cold.
