Severe Weather Coordination Message #2 – Friday 7/25/25 Severe Weather Potential
Hello to all…
..One more day of heat and humidity before a cold front brings slightly cooler conditions for Saturday. A cold front will bring about some relief but will set the stage for Isolated to Scattered Strong to Severe Thunderstorms with strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding as the main threats..
..The Storm Prediction Center (SPC) has expanded the slight risk area to cover much of Massachusetts, Connecticut and Rhode Island away from the Southeast Coast of Massachusetts and Rhode Island where there remains a marginal risk for severe weather. Timeframe for severe weather is between 1-10 PM ET Friday..
..A Heat Advisory remains 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..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible to likely for Friday 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..
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 remain:
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. This will determine how much coverage of strong to severe thunderstorms over 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.
