Tuesday is starting off a bit damp during the early morning hours as overnight periodic rain and drizzle has come to an end. An area of low pressure sits off the coast in the Gulf of Maine, along with a cold front. The low will be pulling away and deepening today. Dry winds from the west on the back side of this low will be picking up during the late morning and afternoon. A Wind Advisory is in effect through 6 PM where winds could gust up to 40+mph for a time. Skies will be turning partly sunny, with mostly cloudy conditions in the NW mountains. Temperatures will start near 50 and climb into the mid 50's during the afternoon. A weak cold front will push through Tuesday night with a few clouds, with cooler air settling in during the overnight hours. High pressure will slide down from Canada and provide slightly cooler air in the 40's for the midweek with sunshine for Wednesday under another upper level ridge sitting over the the northeast.
Another low will track up into the Great Lakes and steer another cold front our way Thursday. Cloudy skies with rain developing for the afternoon and evening. Some gusty winds will be possible with the passage of this front. Friday will be mostly dry with skies turning partly sunny. A deep upper level trough will dig into the Northeast for the weekend with more significant cooler air spilling in from Canada. In fact, it will be the coolest air we have seen this month. Breezy NW winds with building high pressure with a return to seasonal more typical mid December air with highs only in the 30's near 40. Temperatures during the overnights will be in the 20's...so the air will finally be cold enough to get the snow guns going at the ski resorts. What a struggle it has been so far to get things up and running. An unfortunately, it looks like this struggle will continue.
Heading into next week, the weekend cold and trough will lift out with a very warm look returning to the Northeast..especially around the time Christmas Eve into Christmas day! The airmass could end up feeling down right tropical when all is said an done as I expect highs in the 50's and 60's. SW winds will surge the warmth into the Northeast ahead of a strong energized cold front which could be coming with some severe weather and thunderstorms as it tracks eastward. Christmas day is looking wet with rain and mild temperatures. This has the potential to be one of the warmest Christmas' on record and the potential for record warmth. It is still days a way, so slight changes in timing will have big impacts on the forecast. Right now, it appears any dreams of a White Christmas will be just that. Once this front pushes through, I expect a cooler pattern to develop to end out 2015.
