Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms are possible across Western Massachusetts and much of Connecticut later this Thursday Afternoon and Evening after 4 PM as a cold front will bring the end to the heat and humidity in Southern New England. Strong to damaging winds, hail, frequent lightning, and heavy rainfall with urban and poor drainage flooding are the main threats but can’t rule out an isolated tornado if some unfavorable convective parameters for the region are overcome..
..The Storm Prediction Center (SPC) has placed Western and Central Massachusetts and much of Connecticut in a marginal risk for severe weather for Thursday Afternoon and Evening with a slight risk up across portions of Western Maine, Northern New Hampshire and Northern Vermont..
..A Heat Advisory remains in effect through 7 PM Thursday Evening for much of Southern New England except for the East slopes of the Berkshires and Cape Cod and the Islands for heat indices up to 100 degrees. Use caution in the heat by hydrating and taking freaking breaks in air conditioning if exerting yourself outdoors today..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible to likely this 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..
Our final day of heat and humidity occurs today as a cold front will bring cooler and less humid conditions Friday into Saturday. It will set the stage for isolated to scattered strong to severe thunderstorms ahead of the cold front Thursday Afternoon and Evening. The headlines depict the current thinking. Key factors include:

1.) There is favorable shear and satellite imagery shows sufficient clearing for destabilization in the region for later today. Timing of the cold front and forcing with this front seems to be best in Northern New England but we will need to monitor if there is enough forcing to take advantage of favorable shear and instability parameters in the marginal risk area.
2.) There are some limiting severe weather parameters but if they are overcome or better than expected, that could increase the risk for severe weather potential.
3.) Coverage of severe thunderstorms will most likely be isolated to scattered but if items 1 and 2 line up accordingly, it could allow for the severe thunderstorms to be a bit more widespread.

Hello to all…

..Intense Heat and Humidity for today will give way to an isolated to scattered strong to severe thunderstorm and flash flood risk later Tuesday Afternoon and Evening..
..Isolated to Scattered Strong to Severe Thunderstorms are possible across much of Southern New England now though the greater risk is for thunderstorms and heavy rainfall with the secondary risk being severe weather. Frequent lightning and Heavy rainfall leading to urban/poor drainage/river/stream/flash flooding is the main threat for much of the region but a secondary severe weather threat for strong to damaging winds and hail is also possible..
..The Weather Prediction Center (WPC) has continued much of Southern New England in a slight risk for excessive/rainfall and flash flood potential while the Storm Prediction Center (SPC) has expanded the marginal risk for severe weather to much of Southern New England Tuesday..
..A Flood Watch is now in effect from 2 PM Tuesday Afternoon through late Tuesday Night for Northern Connecticut, Providence, Kent, Washington Counties of Rhode Island, Eastern Hampden, Southern Worcester, Norfolk, Bristol, Plymouth and Barnstable Counties of Massachusetts for 1-2″ inches of rain or more falling in an hour or less and any training of thunderstorms causing higher rainfall amounts particularly in vulnerable flood areas could cause pockets of flash flooding in the Flood Watch area..
..A Heat Advisory is also in effect through 8 PM Tuesday Evening for all of Southern New England except for the East Slopes of the Berkshires and the islands for heat indices to 100 degrees. Use caution exerting yourself outdoors, take frequent breaks and stay hydrated/find a location to cool down today..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible to likely Tuesday Afternoon and Evening for severe weather and flash flood potential. 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 more complete coordination message will be posted by 11 AM Tuesday Morning. Below is the NWS Boston/Norton Area Forecast Discussion, WPC Day-2 Excessive Rainfall Outlook and SPC Day-2 Convective Outlook..

**Post Severe Weather Coordination Message for the Thursday 7/3/25 Severe Weather Event, a likely final posting, will be completed later on Tuesday AM**

The headlines depict the current thinking on today’s severe weather, flash flood potential for today across Southern New England. Key factors for today include:

1.) Where a frontal boundary and any seabreeze fronts setup as these will be the locations that have a trigger point for isolated to scattered strong to severe thunderstorms and potential flash flooding.
2.) For the severe weather potential, heating of the day and favorable parameters pointing to severe weather potential overcome limiting factors that could prevent any severe thunderstorm development as the unfavorable factors include things such as weaker wind shear profiles.
3.) As always with severe/non-severe thunderstorm and flash flood events, not all locations will receive a severe/non-severe thunderstorm or flash flood event. They will be isolated to scattered with pockets of wind damage, hail and urban/poor drainage/river/stream/flash flooding in those isolated to scattered locations some of which could be significant if a storm is water loaded enough to bring damaging winds or train over a vulnerable flood area to cause flash flooding.

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms likely across much of Southern New England Thursday Afternoon and Evening and may start slightly earlier between 12-10 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 continued 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. SPC has issued a Mesoscale Convective Discussion indicating an 80% chance of a Severe Thunderstorm Watch or two for portions of New England.
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are 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. The timing appears to be a bit earlier but still seems to be favorable for severe thunderstorm development.
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.
