Some Slick Spots This AM (North)

The National Weather Service in Taunton has posted *Freezing Rain Advisories* for interior MA/VT/NH thanks to a warm front that will lift across the region today.  Temperatures will quickly rise above freezing this AM and rise into the 50's/60's by this evening across Central and SE MA/RI.  Total rainfall today 0.75-1.5".

Short Term Outlook
Here is the regional radar as of 530 AM.  Light rain is beginning in Central/Western MA and it will work into Eastern MA shortly.
NWS Northeast Regional Radar Loop
There will be a bit of a lull between 7-930 AM before the main course arrives.  As of 4 AM the surface warm front is still in PA/MD/VA.
WPC Surface Analysis Northeast 4 AM
Moisture is overrunning the warm and falling in cold areas thus the reason for the Freezing Rain headlines.  That said its pretty much at or just above freezing for much of the region.  Here are the 7 AM temperatures

Looking at these temperatures and the current radar I would say NE MA dodged a bullet this morning with cold air firmly in place but not much precipitation.  That said it only takes a small amount of ice to cause big problems so if travelling towards Lowell, Haverhill, S NH this morning please drive carefully.

The steady rain is back by 10 AM and by 1 PM the entire region will see steady rain.

Temperatures are jumping into the 40's and 50's by this time so expect all precipitation to be rain.  Note the cold air holding on in Central/Northern New England.   That is in sharp contrast to 60's at the CT/RI shore.

A surface low along the warm front will clear the region around 7 PM tonight.  The warm front will likely settle near the MA Pike towards Rt 2.
WPC Surface Fronts/Precipitation Tuesday 7 PM
The rain will exit from west to east beginning 7-10 PM this evening.  A band of heavy precipitation may end the event in RI and SE MA.

With the warm front north of the Pike much of Southern New England surges into the mid to upper 50's (60's SE MA!)

0.75 to 1.5" is my forecast but high resolution computer guidance suggests some amounts greater than 2" are possible although this seems like a low probability.   I'll update tomorrow's forecast later on this afternoon/evening as more rain is in the forecast.   The weekend looks seasonable with temperatures in the 40's and mostly sunny skies.
