Winter Storm Watch Issued

The National Weather Service in Taunton, MA has issued a Winter Storm Watch for portions of Southern New England.
NWS Boston Winter Storm Watches
The watch will likely be upgraded to a warning tonight.  In general 6-12 inches of snow will fall.  Some areas will switch over to mix/freezing rain/rain Sunday morning.  North of the Pike and west of 95 its all snow.

The Storm
An Arctic front will push across New England today.  A cold high pressure system will be placed to our North.  Meanwhile a wave will develop in the Southern portion of the Jet Stream and track towards the Northeast.   Here is the storm moving through Texas, being driven by an upper level low in the Southwest.

Today will be partly cloudy with high temps 20-25.  Tonight temps drop to around 10 degrees.  There is not much of a rebound on Saturday as high temperatures will be in the mid teens.  Snow will hold off until Saturday evening, though a few flurries or light snow showers will be possible during the day Saturday.  The main batch of precipitation arrives after 7 PM tomorrow night.

There are differences in the computer models in regards to the temperature profile.  The NAM is cold with a track grazing the Cape and Islands.  The EURO runs over the Canal.  Either way a good thump of snow is on the way.  Here are the probabilities for 4 inches of snow
WPC Day 2 Snow Probs Snow > 4"
Northwest of the Boston-Prov-Hartford line has a real good chance at seeing 8 + inches of snow
WPC Day 2 Snow Probs > 8"
There is a decent chance someone in MA, S VT, S NH, S ME, or E NY gets over a foot.  Here is the projected surface chart Sunday morning
WPC Surface Forecast Sunday 7 am
By 10 am Sunday the storm will be winding down and should be out of Southern New England by 1 PM.  Perfect timing to get cleaned up and then watch the Pats.  Heres my forecast
Snow totals forecast
If the track is a bit further offshore the 8-12 will expand and push closer to the coast.  I don't like to update but I will tomorrow morning if need be.  Have a good one.
