Severe Weather Coordination Message #1 – Thursday Afternoon & Evening 5/23/24 Severe Weather Potential

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms are possible Thursday Afternoon and Evening anytime between 12-8 PM Thursday. Strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding are the primary threats. The Storm Prediction Center (SPC) has placed nearly all of Southern New England in a marginal risk of severe weather with the greatest potential in interior Southern New England from Boston to Providence north and west..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible Thursday for the severe weather potential..

A pre-frontal trough and cold front will swing through Southern New England Thursday setting the stage for potential strong to severe thunderstorm development. The headlines depict the current thinking. Key factors include:

1.) Amount of cloud cover which is currently expected to be low enough for strong to severe thunderstorm development
2.) Timing of the cold front to maximize the heating of the day
3.) The coverage of strong to severe thunderstorms in the region will depend on the above two factors

SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible Thursday for the severe weather potential. Another coordination message will be posted by 11 AM Thursday Morning. Below is the NWS Boston/Norton Area Forecast Discussion, Enhanced Hazardous Weather Outlook and SPC Day-2 Convective Outlook:
