Severe Weather Coordination Message #1 – Saturday 8/29/20 Severe Weather Potential
Hello to all…
..Isolated to Scattered Strong to Severe thunderstorms are possible across much of Southern New England on Saturday. There is a low chance of an isolated strong to severe thunderstorm overnight to daybreak Saturday with a greater chance for isolated to scattered strong to severe thunderstorms Saturday Afternoon and Evening. The Storm Prediction Center (SPC) has placed all of Southern New England in a marginal risk for severe weather Saturday..
..SKYWARN Self-Activation will monitor the severe weather potential for Saturday..
Another round of severe weather occurred on Thursday but more isolated in nature in the NWS Norton coverage area as the warm front never quite made it through enough of Southern New England to get into our coverage area. Areas of Southwest and South-Central Connecticut saw significant severe weather and the NWS Brookhaven New York is out investigating several areas of significant severe thunderstorm damage in Southern Connecticut. The NWS Boston/Norton Local Storm Report along with the NWS Brookhaven Local Storm Report and Public Information Statement on damage surveys are listed below:

For Saturday, a warm front will be able to push through Southern New England and there will be strong wind shear again in the upper levels of the atmosphere for severe thunderstorm development. Instability, however, could be quite marginal due to cloud cover. If the strong wind shear conditions in the upper levels of the atmosphere can overcome lower instability values or more clearing develops to allow for greater instability, the severe weather potential in our region would be increased and this will bear watching.
SKYWARN Self-Activation will monitor the severe weather potential for Saturday. Another coordination message will be posted by 1000 AM Saturday Morning. Below is the NWS Boston/Norton Area Forecast Discussion, Enhanced Hazardous Weather Outlook and SPC Day-2 Convective Outlook:
