Severe Weather Possible this Evening-UPDATE 308 PM

UPDATE
The storm prediction center has issued a Severe Thunderstorm Watch until 930 PM tonight.  Here are the areas potentially affected this afternoon and evening courtesy of SPC.

There is a moderate chance of severe to potentially hurricane force wind gusts in these storms.  Downburst winds and hail to 2 inches in diameter are the main threat.  Downburst winds can be as devastating to an area as a small tornado.  If skies darken take cover immediately. 

                                                                                                                     

Severe weather is possible this evening, mainly between 6 pm and midnight.  Here is the national outlook by the Storm Prediction Center (SPC) based out of Norman, OK (Oklahoma for you geography illiterate).

The main threat will be damaging straight line winds.  There is also a low chance of hail accompanied with these storms.  The best chance of severe storms is northern and western New England, as you can see above.

The afternoon will be hot and humid, no changes to last night's forecast.  For the Blackstone Valley, thunderstorm's look like they will hold together and pass through between 8 and 11 pm tonight.  Here is the North American Model (a short range model) simulated radar for tonight

Tough to see, but there is a line of storms across the CT/RI/MA border

Now for tomorrow's hourly forecast

Humidity will decrease as the day goes on tomorrow.  However there is a slight chance of a passing shower or thunderstorm around 5 PM.  This is less than 20% but it is something to be aware of.  Highs will reach 85-87 across most of the region.
