Low pressure has emerged out of the Gulf States and will be positioned near the Virginia Capes by midday Sunday. It then moves across Cape Cod early tonight and quickly departs for the Maritimes by early Monday. This is a fairly quick hitting and short duration storm and it will also be mainly a rain event in the local area.
The onset of rain is expected by early in the afternoon and by mid to late afternoon will pick up in intensity. Most of the precipitation should be done before midnight as the low begins to depart. As it does so much cooler air will be dragged in behind the storm system with a mix and changeover to snow through the far interior likely before the precipitation ends. As for rainfall amounts a general 1 to 1.5 inches should fall across the area with a few spotty 2 inch totals possible. Any changeover to snow locally would produce a coating to less than an inch, mainly along and outside of the Route 495 corridor. A few flakes could mix in all the way to the coast. Winds will ramp up tonight and the National Weather Service does have a Wind Advisory in place for eastern Essex County from 5 pm this afternoon until 1 am Monday morning, for winds that could gust to at least 35 mph along the coast during that time. Winds will be even stronger south of the city and over Cape Cod where gusts to 50 mph, or higher, may occur.
If you are attending the Patriots game late this afternoon and evening expect a windswept cold rain and temperatures hovering near 40.
Once the storm moves out the much colder air continues to transfer into the region on Monday and Monday night. Although the mercury will hold its own on Monday, gusty winds make for a cold and blustery day.
The really cold arctic air takes hold Monday night and will be with us as we welcome the New Year. If you are going to be outdoors New Years Eve it is best to dress in layers, especially if you are going to be taking in first night festivities in Boston. Temperatures will be reduced to the teens with wind chills in the single digits to near zero. Also, a disturbance will move through Tuesday and New Years Eve, possibly dropping a few snow flurries. More importantly, another wind driven push of arctic air will follow maintaining a very cold New Years Eve and New Years Day.
Attention then focuses on a storm moving out of the Plains States and into the lower Ohio Valley. The system will then move to the East Coast and redevelop Thursday. This system could very well bring significant impacts to the area Thursday and Friday in the form of snow and wind. Too early to nail down anything specifics but right now it looks like a snowstorm may be in the cards later Thursday, Thursday night and into Friday. Just in time for the kids return, or maybe not, to school!
