An active weather pattern continues into the upcoming weekend. After two days of unsettled weather, with precipitation falling in various forms, we will now be treated to the coldest air of the season both Thursday and Friday before another storm system brings unsettled weather over the weekend.
A cold front will approach New England Wednesday and is poised to move across eastern Massachusetts at night. On the backside of the front arctic air spills into the region on gusty west winds and brings us a couple of days, and nights, of frigid temperatures with much below normal readings. Gusty winds on Thursday will make it all the more uncomfortable as wind chills dip to around 10 degrees at times during the day, then to zero or below at night. There is just a slight chance of a passing flurry Wednesday night as the front moves across the area, otherwise the Wednesday through Friday period is dry and very cold. Sunshine each day will do little to nothing in the way of bringing any comfort to the cold blast on Thursday and Friday.
However, Friday could be the proverbial calm before the storm as we watch for a potential storm over the weekend. Although models have struggled with this so far there are some hints beginning to emerge that we could see an extended period of storminess from late Saturday or Saturday night right through Sunday night. With the cold air in place we will most likely see some snow but it is still too early to pinpoint the precipitation impacts at this time. Just be aware that something, potentially big, is brewing for the weekend.
The forecast maps place a low pressure system near Long Island early Sunday morning and a second low just off the North Carolina coast, merging into one large storm over the Canadian Maritimes by Monday. There is the potential for a significant impact of weather from these systems. More on this tomorrow.
