Hello to all..

..Isolated to Scattered Strong to Severe Thunderstorms occurred particularly in Western and Central Massachusetts and Northern Connecticut Sunday afternoon through early evening. The event was handled via SKYWARN Self-Activation mode from approximately 11 AM-8 PM Sunday..
..An isolated strong to severe thunderstorm is possible Monday Morning. As we move into Monday Afternoon and Evening, another round of isolated to scattered strong to severe thunderstorms are likely across interior Southern New England, particularly Southern New Hampshire, interior Massachusetts and interior Connecticut and possibly Northern Rhode Island. The Storm Prediction Center, SPC, has maintained a 5% severe weather probability for this region..
..SKYWARN Activation with Ops at NWS Taunton will commence between noon-1 PM on Monday..

A warm front made its way through Southern New England Sunday Morning into early afternoon bringing with it strong to isolated severe thunderstorms. This included a funnel cloud and minor wind damage in Springfield, MA with flooding reports and house fires from lightning in Central Massachusetts. After the warm front passed, sufficient clearing and destabilization with an impulse moving through the area resulted in another round of scattered severe thunderstorms impacting portions of Western Massachusetts and Northern Connecticut between 430 and 800 PM. SKYWARN Self-Activation handled the storm activity today across the region. Hardest hit areas were in the second round of storms over West Springfield, Agawam, Longmeadow and then extending into Enfield, Somers and Tolland Connecticut with pockets of wind damage reaching the Storrs/Mansfield, CT area. Any additional damage reports or pictures can be shared as a reply to this email or to pics@nsradio.org with credit given to the spotter for the photos posted.

As look at today’s severe weather potential, there is a round of heavy rain and embedded thunderstorms ongoing with one warning issued for an isolated strong to severe thunderstorm over Northeast Franklin and Southwest Cheshire County New Hampshire as of 725 AM. This should move out of the area with the possibility of heavy rain and embedded thunderstorms scraping Southeast New England from a second area offshore. In between these two areas, the key item on severe thunderstorm coverage will be amount of clearing that takes place. If there is sufficient clearing and heating, that will set the stage for potential clearing and heating for another round of isolated to scattered strong to severe thunderstorms in interior Southern New England particularly in southern New Hampshire, interior Massachusetts, interior Connecticut and possibly Northern Rhode Island. Strong to damaging winds, hail, and urban and poor drainage flooding are the main threats. The threat timeframe is after noon on Monday.

SKYWARN Activation with Ops at NWS Taunton will commence between noon-1 PM on Monday. This will be the last coordination message on today’s threat. Below is the NWS Taunton Hazardous Weather Outlook and SPC Day-1 Convective Outlook:
