Severe Weather Coordination Message #2 – Saturday Afternoon & Evening 5/3/25 Severe Weather Potential
Hello to all…
..Isolated to Scattered Strong to Severe Thunderstorms are possible to likely Saturday Afternoon and Evening between 2-10 PM across Western, Central, Northeast Massachusetts, Northern Connecticut and Northwest Rhode Island where the Storm Prediction Center (SPC) has placed Western and Central Massachusetts and Northwest Connecticut in a slight risk for severe weather with a marginal risk for severe weather from Northeast Massachusetts to Northwest Rhode Island and Northeast Connecticut. Strong to damaging winds, hail, frequent lightning and heavy downpours causing urban and poor drainage flooding are the main threats..
..SKYWARN Self-Activation will monitor any severe thunderstorm potential Saturday Afternoon and Evening..
Severe thunderstorm potential has increased since the Friday evening update across Western and Central Massachusetts and Northwest Connecticut which is now in a slight risk for severe weather with a marginal risk further east to north and west of the I-95 corridor. The headlines depict the current thinking. Key factors include:
1.) Sufficient heating and destabilization for strong to severe thunderstorm development. Satellite imagery currently shows sufficient clearing for heating and destabilization for severe thunderstorm development.
2.) Timing of forcing and triggering of the atmosphere at the time of peak heating which is currently lined up appropriately for isolated to scattered strong to severe thunderstorm development.
3.) As always with severe thunderstorm events, not all locations will receive a severe thunderstorm. They will be isolated to scattered with pockets of wind damage, hail and urban/poor drainage flooding in those isolated to scattered locations.
SKYWARN Self-Activation will monitor any severe thunderstorm potential Saturday Afternoon and Evening. This will be the last coordination message as we shift into operations mode. Below is the NWS Boston/Norton Area Forecast Discussion, Enhanced Hazardous Weather Outlook and SPC Day-1 Convective Outlook.
