Severe Weather Coordination Message #1 – Thursday Afternoon and Evening 7/14/22 Severe Weather Potential

Hello to all…

..After the most organized severe weather event so far in this quite summer season of severe weather on Tuesday 7/12/22, isolated strong to severe thunderstorms are possible in Eastern Massachusetts and Rhode Island this Thursday mid-afternoon to early evening particularly along any seabreeze boundaries that form in and around the marginal risk area. Strong to damaging winds, hail, frequent lightning and localized heavy rainfall leading to brief urban and poor drainage flooding are the main threats..
..The Storm Prediction Center (SPC) has placed much of Eastern Massachusetts in a marginal risk for severe weather this Thursday Afternoon and Evening..
..SKYWARN Self-Activation will monitor any isolated strong to severe thunderstorm potential for this Thursday Afternoon and Evening..

Tuesday 7/12/22 featured the most organized severe thunderstorm event in what has been a quiet summer season of severe weather for Southern New England.

For today, we are not expecting an organized severe weather event like Tuesday 7/12/22 but strong instability with some strong upper level winds aloft along with a trigger via seabreeze fronts/boundaries could allow for isolated strong to severe thunderstorms in Eastern Massachusetts and Rhode Island and SPC has upgraded much of Eastern Massachusetts to a marginal risk for severe weather. SKYWARN Self-Activation will monitor this potential for this Thursday Afternoon and Evening.

This will be the only coordination message as we shift into operations mode. Below is the NWS Boston/Norton Area Forecast Discussion and SPC Day-1 Convective Outlook:
