There is a Chance...
Amazing to plot temps today...cold air remained dammed in Central and Northern New England through the evening with temps in the 50s in Boston and in the 30s just up the road where icing was an issue in many places. The warmth will win out tonight...the surface front will work through overnight and warmer air will mix down to the surface. Drier air will also work in and supply us with tons of sunshine tomorrow...the first day of Winter will once again feel Spring-like!
Friday is looking much beefier now...low pressure will eject out of the Gulf of Mexico, loaded with moisture. Rain will overspread the area tomorrow night. At the same time a cold dome of high pressure will be on the move and ageostrophic northerly flow will glide colder air into the storm. Rain will be changing to snow early Friday morning from NW to SE. The rain snow line will likely stall out near Boston, but north and west of the city there is a very good chance for a couple of inches of snow. Right now it looks like 1-3 inches NW of 495 with an inch or less inside of 495. This will cause problems for the Friday AM commute...thankfully, many have an extra long weekend and won't be on the roads. The storm will be a very fast mover and will be gone by midday.
In the wake of the storm, NE winds will prevail and ocean effect snow showers and flurries are likely on Saturday...there is a chance for some coatings near the coast, but not much more. The XMAS Day storm is now looking like a miss as all available guidance slides the storm south of us.
While we aren't looking at a lot of snow over the next few days what ever we get will likely stick through XMAS Day as the temps over the weekend will not get out of the 30s...making for a white Christmas for some!
