..The Storm Prediction Center (SPC) has placed much of Western and Central Massachusetts, Most of Connecticut and Northwest Rhode Island in a slight risk for severe weather with a marginal risk for severe weather across the rest of Southern New England. Timeframe for severe weather is between 1-9 PM ET Friday..
..A Heat Advisory is in effect through 8 PM Friday for all of Southern New England except for the east slopes of the Berkshires, South Coastal Massachusetts and Rhode Island including Cape Cod and the Islands with heat indices up to 103 degrees. Use caution in working outdoors, take frequent breaks, spend time in cooler areas and stay hydrated..

One more day of heat and humidity before a cold front brings some relief to heat though it will remain humid this weekend. The headlines depict the current thinking. Key factors include:
1.) The timing of the cold front which looks favorable for severe weather development currently.
2.) Frontal forcing, instability and wind share to offset some unfavorable severe weather parameters.
3.) As always with severe/non-severe thunderstorm events, not all locations will receive a severe/non-severe thunderstorm. They will be isolated to scattered with pockets of wind damage, hail and urban/poor drainage flooding in those isolated to scattered locations.
