New England Weekend Outlook 6/2-6/4/17

It's that time of year again when the Thursday PM commute starts to look like the Friday PM commute and the Friday PM commute just sucks.  If you have ever left the Boston area on a Friday in summertime you know exactly what I mean.  The silver lining is a lot of people are heading off to weekend getaway's so let's focus on the positive and give the forecast for the vacation regions of New England.  In this case, it's the destination that matters, not the journey.

Short Term Outlook
An upper-air disturbance with a pocket of cold air will enable the development of scattered showers and thunderstorms across all of New England this afternoon.  The regional radar is showing some shower development in upstate NY and Northern New England.
NWS Northeast Regional Radar 1108 AM
An upper-level trough will serve as the trigger for shower and thunderstorm development.  It is shown here in the projected 2 PM surface chart.
WPC Surface Fronts/Precipitation Friday 2 PM
The showers will pop around 1 PM in Southern New England and coverage will be regionwide until 7 PM or so.  It won't rain the entire afternoon, but some communities will see multiple showers/thunderstorms.  Here is the 18-hour simulated radar through 3 AM.

The strongest storms today will produce frequent lightning, gusty winds, heavy rain, and small hail.  

Northern VT. NH and ME will struggle to get out of the 50's today.  Temperatures will be in the upper 60's/low 70's in Southern ME and Southeast NH.  Temperatures will rise into mid 70's for much of Southern New England.  Even across Cape Cod temperatures will be near 70.

Some AM showers will be possible as the upper-level disturbance continues to rotate through.  There will be more sun than clouds in Southern New England but in Northern New England showers will be possible through the late afternoon.  Rain chances in Southern New England diminish greatly after 12 PM.  Clouds and drizzle will hold on longest for the Cape, Islands, and South Coast in SNE.  Downeast Maine and the higher elevations of NNE will have the greatest chance of PM showers.

The Dierks Bentley show in Mansfield will be dry.  Tailgate temperatures will be mid 60's.  It's a weekend to avoid the campsite's up north for recreational activities.  Max temperatures will be in the upper 40's and low 50's across VT/NH.  The coastal communities in Southern ME and NH will be in the low 60's.   It will be much warmer in Southern CT/RI so if you want to hit the beach I would go there.

That makes temperatures in NNE 15-20 degrees below average for this time of year.

Minimum temps Saturday night will drop into the upper 40's so if you have outdoor plans pack the jeans and sweatshirt.  

Sunday will start dry across all on New England.  The chilly temperatures will make it feel more like late April than early June.  A storm system approaching from the Great Lakes will bring rainfall to the region Sunday PM into Monday AM. 
WPC Surface Fronts/Precipitation Sunday 8 AM
Some showers are possible around after 1 PM but the steady rain arrives later in the afternoon.  Temperatures will be in the upper 60's/low 70's so its not the worst weekend weather day ever.

The 8 PM simulated radar is showing scattered coverage all across New England.

This rain will be mostly associated with the warm front lifting north.  More rain will fall overnight Sunday into Monday as low pressure crosses the area.
