The Friday storm lived up to its billing with heavy rain, howling winds, and record warmth in Southern New England. Widespread showers continue through the evening before it dries out some overnight. Temperatures stay mild in the 40s/50s with a lot less wind overnight. Expect mist and fog to develop. A few showers are possible on Saturday, but it should be dry most of the time. Expect temps in the upper 40s to mid 50s in the mid-morning, but it will turn cooler in the afternoon – falling into the 30s by late in the day. Sunday will be a quiet and seasonably cool day with mostly sunny skies and highs in the upper 30s.
That Alberta Clipper that I’ve been talking about for a while is still in the forecast for Sunday night into Monday. It will not have much precipitation to work with, but could squeeze out an inch of snow in some spots. The highest likelihood for an inch of snow is north and west of the I-84 corridor in Connecticut. It’s about 50/50 for a coating-1″ of snow in the rest of Southern New England including coastal Connecticut and all of Rhode Island. The timing is between midnight and 10 am from west to east. So, western CT has more of a 12am-6am time frame, and RI is between 3am-10am. The temperature will be near freezing and with the threat of snow before dawn, there could be a few slick spots early Monday. It’s a weak system, so it’s still possible that it’s nothing more than flurries and sprinkles with no impact/accumulation.
EPS snow accumulation map is not impressive – generally a coating-1″ event at worst in Southern New England early Monday
The weather looks quiet for Christmas Eve and Christmas Day. Expect highs in the upper 30s on Monday, and lows in the 20s Monday night under partly cloudy skies. It will be in the upper 30s again with some sun on Christmas. Dry weather likely continues through the midweek. A storm late in the week looks like it will bring mainly rain to Southern New England.
