Slow moving AM rain showers will all but dissipate by 8 AM.  The rest of the day will be mostly cloudy with some breaks of sun.  A cold front will cross the region tonight resulting in overnight showers/thunderstorms.  Southern New England will be in the "warm sector" today which means it will be quite humid this afternoon.

General Overview
Here is the cold front slowly moving towards New England
WPC Surface Analysis 2 AM
The cold front will touch off some severe thunderstorms in Eastern PA through upstate NY into VT
SPC Severe Weather Outlook Tuesday 
Some of these storms may impact Western MA/CT but they will form after 7 PM.  Here is the 7 PM radar snapshot

Temperatures today reach the upper 70's/low 80's
NWS NDFD max temp forecast Tuesday (image Weatherbell)
Dew points will rise into the mid 60's.  These conditions stay around tonight which is our best chance for good rain.  Optimistically we could squeeze out over a 0.5" tonight (more to our North and West)
WPC Day 1-2 precip forecast 
The front slowly clears tomorrow.  A few showers will be possible but overall it will be warmer and nicer than today.  High pressure takes control Thursday.  I'll post on the long weekend tomorrow.
