Hot and Humid With Thunderstorms By End of Week

Widespread summer heat will work into Southern New England over the next few days.  The heat will help establish an unstable air mass by later this week.  Multiple rounds of showers and thunderstorms will impact the region Thursday PM through Saturday.

General Overview
WPC Surface Analysis 2 PM
The 2 PM surface chart shows departing low pressure near Cape Cod.  This is the system that was responsible for this morning's rain.  The upper level pattern shifts to an anticyclonic one behind this low..  As a result temperatures surge into the mid 90's tomorrow.

The sea breeze stays at the coast tomorrow so the beach looks like a great place to go.  Dew points will be in the low to mid 60's inland tomorrow but closer to 70 near the coast.  That isn't atypical for July as it is the classic Hazy, Hot and Humid weather that characterizes the summer.  As a result an Air Quality Alert has been issued for RI/CT E MA.  This may expand into Worcester County and NW Middlesex County later tonight.
NWS Boston Alerts 
There will be no real relief at night with temperatures only dropping into the upper 60's.  Thursday will see temperatures near 90 again with dew points well into the 60's/near 70 in spots.  This lead to miserable heat/humidity.  A disturbance will move through later Thursday PM.
WPC surface analysis 8 PM Thursday 
As a result the region will have to be on guard for PM showers/thunderstorms.  A series of disturbances will follow this one so Friday and Saturday will also have a threat of showers and thunderstorms.  More on this as the specifics become clear.
