Severe Weather Coordination Message #1 – Friday Afternoon & Evening 6/6/25 Severe Weather Potential
Hello to all…
..Isolated to Scattered Strong to Severe Thunderstorms are possible to likely Friday Afternoon & Evening between 2-10 PM across Western, Central, Northeast Massachusetts, Northern Connecticut and Northwest Rhode Island where the Storm Prediction Center (SPC) has placed this area in a slight risk for severe weather with a marginal risk for severe weather for North-Central Rhode Island and the rest of Eastern Massachusetts away from the south coast. 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 Friday Afternoon and Evening..
Severe thunderstorm potential is on tap for much of interior Southern New England. The headlines depict the current thinking. Key factors include:
1.) Sufficient heating and destabilization for strong to severe thunderstorm development. This is dependent on any remaining convective activity and if any of it spills over with lingering cloud cover in the region.
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. While wind fields are marginally sufficient for severe thunderstorm development, other instability parameters are favorable and will bear watching.
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 Friday Afternoon and Evening. The next coordination message will be posted by 11 AM Friday Morning. Below is the NWS Boston/Norton Area Forecast Discussion, Enhanced Hazardous Weather Outlook and SPC Day-2 Convective Outlook.
