Heat & Severe Weather Coordination Message #5 – Thursday 7/2/26 Through Saturday 7/4/26 Heat & Severe Weather Potential

Hello to all…

..Isolated strong to severe thunderstorms occurred in portions of interior Massachusetts and Northwest Rhode Island late Wednesday Night into early Thursday AM with a complex of strong to severe thunderstorms that moved through the region. The WX1BOX Amateur Radio Report log for Wednesday 7/1/26 through early Thursday AM 7/2/26 is included in this update along with the WX1BOX Amateur Radio Report Log from the Tuesday 6/30/26 severe weather event..
..Intense Heat Wave ongoing for much of Southern New England and continues through Saturday. Severe Weather potential for Thursday is lower than the last two days but there is a non-zero risk for strong to severe thunderstorms this Thursday PM and evening with a greater risk for severe weather for Southern New England Friday Afternoon through Saturday Evening..
..For Thursday, the Storm Prediction Center (SPC) has placed Southern New England is in a general risk for thunderstorms with a lower severe weather risk than prior days but it is a non-zero threat. For Friday, Southern New England is in a marginal risk for severe weather and Saturday has Southwest Massachusetts and much of Connecticut in a marginal risk for severe weather though all areas should monitor. These areas may shift and upgrade/downgrade in future updates..
..Strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding would be the main threats.. Areas outside of the severe weather risk area should also monitor conditions today through Saturday with the greatest risk Friday Afternoon to Saturday Evening at this time..
..Timing any severe weather potential is uncertain and will depend on impulses in the atmosphere, how close those impulses come to Southern New England and how any thunderstorm/convective development the prior day affects the next day’s convective potential..
..An Extreme Heat Warning is in effect through 8 PM Saturday Evening for the entire NWS Norton Coverage Area except Cape Cod and the Islands for Heat Indices up to 115 degrees. A Heat Advisory is in effect through 8 PM Saturday Evening for Cape Cod and Marthas Vineyard for heat indices up to 104 degrees. Those working and recreating outside should take frequent breaks in Air Conditioned comfort and drink plenty of liquids. It is noted low temperatures are unlikely to get below 70 degrees and in a fairly large portion of the area may not get below 75 degrees meaning little relief to the heat during overnight hours..
..SKYWARN Self-Activation with Amateur Radio-Call Up Nets will monitor any severe weather potential Wednesday and Beyond. Pictures and videos of wind damage, hail, flooding etc. can be sent as a reply to this email, via our Facebook/X/Bluesky feeds or the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated. The next coordination message will be posted on Friday by 1100 AM..
