Severe Weather Coordination Message #1 – Tuesday 8/9/22 Heat & Severe Weather Potential

Hello to all…

..Last day of heat and humidity today for the region. Showers and thunderstorms remained below severe limits on Monday while thunderstorms Friday brought isolated severe weather to portions of interior Massachusetts and neighboring Southern New Hampshire during Friday Afternoon into early evening and isolated severe weather also occurred Sunday Afternoon and Evening in isolated to scattered locations. Saturday all storms stayed non-severe..
..Isolated to Scattered Strong to Severe Thunderstorms with strong to damaging winds, hail and heavy downpours leading to possible urban and poor drainage flooding are the main threats. The threat area is much of Southern New England with the best chance along or south of the Mass Pike over isolated locations.. Severe weather is expected to be similar or perhaps slightly higher than the coverage seen on Friday and Sunday though if instability, timing of front and stronger though still marginal shear do not coincide accordingly, thunderstorms could remain non-severe but the setup favors at least some isolated coverage of strong to severe thunderstorms..
..Owing to the slightly better chance at more coverage of strong to severe thunderstorms, the Storm Prediction Center (SPC) has placed much of Southern New England in a marginal risk for severe weather..
..A Heat Advisory is in effect through 800 PM Tuesday for all of the coverage area except Nantucket for heat indices in the 98-102 degree range. If outdoors and physically exerting yourself, slow down, take frequent breaks and drink plenty of non-caffeinated liquids..
..SKYWARN Self-Activation will monitor the severe weather potential for this Tuesday afternoon and evening anytime from 1200-1000 PM today. This will be the only coordination message as we shift to operations mode.
