Cool Unseasonable Weather for the Next Few Days

A fresh snow pack was laid down yesterday for many.  Others got some snow, then sleet and heavy rain.  You can find snow totals here.  Things look like they are quieting down (fingers crossed) for now.  There is no real spring warmth in sight so the snow threat is not gone for 2012-13 yet.

Current Conditions
Temperatures are cold this morning

There will not be much of a rebound today either.  The surface chart looks like this
WPC Surface Analysis 330 am
Winds are out of the west around the elongated low pressure center in Northern New England.  There is still some snow in Maine
NWS northeast regional radar
Short Term Forecast
A partly cloudy day with below average temperatures.  It will be above freezing in Southern New England, but not by much.  CT, RI, and SE MA (includes Cape and Is) will be in the upper 30's and perhaps 40.  The rest of us will be in the low to mid 30's.

This morning will see more sun than this afternoon.  A deck of clouds looks to shift in this afternoon.  We stay dry until tomorrow afternoon (more on that in a minute).  Tonight temperatures drop 10-15 degrees below normal.

In Northern New England temps drop into the teens.  In Southern New England widespread 20's.  Tomorrow a storm passes by offshore but may be close enough to interact at the mid levels of the atmosphere.  Most of the action should be confined to SE MA, Cape and Islands.  Here is the expected precipitation in the next 3 days
WPC 3 day precipitation totals
I would think the Cape sees several inches of snow.  Southern Bristol and Plymouth County are also likely to see a few inches.  These type of features are difficult to forecast as they depend on very small scale features that models do not see well.  This would start tomorrow afternoon.  I am not going to promise anything outside of 95 as of now.  Temperatures will be in the mid 30's
06z NAM hires 2 m temps Thur 1 PM (image weatherbell)
Long range discussion either tomorrow or Friday.  Have a good day
