Hello to all…
..A Cold front will bring a threat of severe weather and an end to the latest round of heat and humidity today making for a nice seasonable weekend.

..Isolated to Scattered Strong to Severe Thunderstorms are likely today across much of Southern New England with a slightly higher threat area along and south of the Mass Pike to the coastal areas today. Strong to Damaging Winds, frequent lightning and heavy downpours with urban and poor drainage flooding are the main threats. The Storm Prediction Center (SPC) has placed all of Southern New England in a marginal risk for severe weather today. The main threat timeframe is from 2-10 PM today..
..SKYWARN Activation with Ops at NWS Boston/Norton will commence by 1-130 PM today for this severe weather potential..
One last day of heat and humidity ahead of a cold front will set the stage for isolated to scattered strong to severe thunderstorms across much of Southern New England as a cold front swings through the region bringing more seasonable weather for this weekend. There will be sufficient heating and destabilization with marginally sufficient wind shear to allow for isolated to scattered strong to severe thunderstorms across the region. The extent of coverage of strong to severe thunderstorms is a bit uncertain given the strongest wind shear is somewhat disconnected from the higher instability areas and other marginal factors associated with the cold front but there looks to be enough parameters in place for at least isolated to scattered coverage of strong to severe thunderstorms. If the stronger wind shear becomes closer to the higher levels of instability in place in Southern New England and other severe weather parameters improve, that could set the stage for a more potent severe weather episode but current thinking is for more isolated to scattered strong to severe thunderstorms in the area.
SKYWARN Activation with Ops at NWS Boston/Norton will commence by 1-130 PM today for this severe weather potential. This will be the only coordination message on this severe weather potential as we move into operations mode.
