Heat & Severe Weather Coordination Message #7 – Saturday 7/4/26 US Independence Day Heat & Severe Weather Potential

Hello to all…

..Happy Independence Day to all Amateur Radio and non-Amateur Radio SKYWARN Spotters and we appreciate everyone’s support of the SKYWARN program and celebrate America’s 250th Birthday. We hope everyone enjoys the holiday and also keeps a watchful eye on today’s severe weather potential..
..Friday continued extreme heat over Southern New England but less thunderstorm activity than prior days with strong thunderstorms doing minor wind damage in parts of Berkshire County Mass late Friday Night before weakening moving into our coverage area. The WX1BOX Amateur Radio Report log for Thursday Evening 7/2/26 and for the 7/1/26-7/2/26 and 6/30/26 severe weather events remain in this update..
..Intense Heat Wave winds down today, Saturday July 4th 2026, with very slightly cooler conditions which has meant the Extreme Heat Warning has been downgraded to a Heat Advisory but nonetheless caution is advised to stay cool due to several prior days of extreme heat and hot and humid conditions will continue today..
..A Heat Advisory is now in effect through 8 PM Saturday Evening for the entire NWS Norton Coverage Area except Nantucket for heat indices up to 102. Those working and recreating outside should take frequent breaks in Air Conditioned comfort and drink plenty of liquids. Conditions tonight should be a bit better than previous nights and much improved on Sunday from a heat perspective..
..For Saturday, there will be higher instability across the Mid-Atlantic states to our southwest but there will remain sufficient instability, energy, forcing, and wind shear for Isolated to Scattered Strong to severe thunderstorms across much of Southern New England with the greatest risk in Southwest Massachusetts and Connecticut. The Storm Prediction Center (SPC) has placed most of Connecticut in a slight risk for severe weather and the rest of Southern New England in a marginal risk for severe weather. Timeframe is between 2 PM-12 AM Saturday. Strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding would be the main threats..
..SKYWARN Self-Activation with Amateur Radio-Call Up Nets will monitor any severe weather potential this Saturday PM and Evening. 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. This will be the last coordination message on severe weather and heat potential as the heat wave breaks. Storm Coordination messages may be posted for soaking rainfall potential later Sunday into Tuesday for the region..
