Severe Weather Coordination Message #1 – Thursday PM/Evening 7/3/25 Severe Weather Potential
Hello to all…
..Isolated to Scattered Strong to Severe Thunderstorms are possible to likely across much of Southern New England Thursday Afternoon and Evening between 2-10 PM. Strong to damaging winds, hail, frequent lightning and torrential rainfall leading to urban and poor drainage flooding are the main threats as a cold front will usher in cooler and less humid air for a beautiful 4th of July weekend..
..The Storm Prediction Center (SPC) has a slight risk of severe weather for Western and much of Central Massachusetts, all of Connecticut and nearly all of Rhode Island with a marginal risk for severe weather for the rest of Southern New England..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible to likely for the severe thunderstorm potential for Thursday Afternoon and Evening. Pictures and videos of storm damage, hail, and flooding can be sent as a reply to this email, via our WX1BOX Facebook, X and Bluesky feeds or to the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated..
A cold front will usher in cooler and less humid air for a beautiful 4th of July weekend but will bring with it the potential for isolated to scattered strong to severe thunderstorms for much of Southern New England. The headlines depict the current thinking. Key factors include:
1.) Amount of moisture convergence coupled with instability, cooling temperatures aloft in the atmosphere and reasonably strong wind shear potential to allow for severe thunderstorm development and how wide the coverage will be in the region.
2.) Timing of the cold front near the timing of peak heating to take advantage of the favorable parameters presuming level of moisture convergence is sufficient for severe thunderstorm development. This will also dictate severe thunderstorm coverage in the area.
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.
