Strong Thunderstorms Possible Today

A cold front approaching from the west will fire off strong to severe thunderstorms this afternoon and evening.  Ahead of these storms we will find temperatures in the low 90's.  Add in the humidity and it will feel closer to 100.  The storms will first impact the Berkshires/western MA between 2-3 PM, Worcester County/Hartford 3-6 PM and Boston/Eastern MA 4-730 PM,  Damaging winds are the number one threat today along with frequent lightning.  Hail and an isolated tornado (especially Western MA and into New York) are also possible.

General Overview
The SPC has issued a slight risk for Western New England and a marginal risk for Central/Eastern New England
SPC Day 1 Severe Weather Outlook
Here is the cold front as of 2 AM.  As the warm front lifts through to our west it will help to re-enforce the heat and humidity providing fuel for the thunderstorms.

High temperatures today are low 90's although some places in Eastern MA may hit the mid 90's.

It will be a great beach day along the South Coast up until the storms arrive so if you are planning a quick trip to the shore that will be the place to go.  We stay mostly dry until Friday after this so hopefully we can receive some beneficial rain.  After all we still have this

If possible I'll try to live stream a video as the storms roll through.
