The messy winter storm that brought a slushy combination of snow and rain to Southeastern New England will move out of the picture on Sunday. Watch your step in the morning as any snow, slush, and puddles will freeze overnight as temperatures fall into the mid to upper 20s by dawn. It will be mostly sunny, breezy, and cool on Sunday afternoon. Highs will be in the mid 30s.
The break between storms will not last long, and the one heading our way next week could be very impressive. Jet stream energy coming through the Midwest on Monday will reach the Mid-Atlantic coast late in the day and a large storm will rapidly intensify and very slowly move northeast to east of Nantucket Tuesday into Wednesday.
It will be a clear and very cold start to the workweek. Lows Monday morning will be in the upper single digits to mid teens. Clouds will increase on Monday, and snow will likely develop late in the afternoon or during the evening. Highs will be in the upper 20s to low 30s on Monday. Based on the projected storm track, there should be ample cold air for an all-snow event in Southeastern New England.
Snow may become heavy by late Monday night, and the brunt of the storm could be Tuesday morning with wind-driven snow and near-blizzard conditions. The temperature will fall into the teens and 20s by early Tuesday, and snow will continue through the day, and possibly through the night into Wednesday morning. Winds will howl, with the strongest gusts likely on Cape Cod and the islands. 
Obviously, with a 30-42 hour storm projected, we are expecting hefty snow totals. It’s a little early to project them on a map, but more than a foot of snow is possible in the hardest hit areas. In a worst-case scenario, this storm could rival some of the bigger Southern New England blizzards in the last ten years.
The storm will slowly drift away in the midweek, and we expect dry weather Wednesday afternoon and Thursday. It will be very cold with highs in the 20s and lows in the single digits and teens. More (gulp) snow is possible on Friday…we’ll keep you posted.
