Severe Weather Coordination Message #2 – Sunday June 2nd, 2013 Potential Severe Weather Event

Hello to all..

..Isolated to Scattered Strong to Severe Thunderstorms likely particularly over Southern New Hampshire, Western and Central Massachusetts and Connecticut during the afternoon and evening. Damaging Winds, large Hail and urban and poor drainage flooding are the main threats with the Storm Prediction Center (SPC) continuing a Slight Risk for Severe Weather in these areas. Areas to the east should monitor as an isolated strong to severe thunderstorm threat is possible eventually evolving into an urban and poor drainage flooding later Sunday into Monday..
..SKYWARN Activation with Ops at NWS Taunton will commence at Noon today..

At 945 AM, Satellite imagery shows clear skies over much of interior Southern New England. This will allow for significant heating and destabilization during the entire day across much of the interior. Satellite imagery shows the prefrontal trough and cold front across Central and Western New York moving east-northeastward with southwest wind flow ahead of the front. The frontal timing will be the key to the extent of severe weather over the region today. Based on current model projections and trends, the most likely area for severe weather is over the current SPC Slight Risk area from Southern New Hampshire into Western and Central Massachusetts and Connecticut. In this area, isolated to scattered strong to severe thunderstorms are likely with damaging winds, large hail and urban and poor drainage flooding as the primary threats. The severe thunderstorms will likely involve a couple short lines or possibly a squall line of activity. An Isolated supercell or two is possible before the activity involves into short lines or a single squall line of activity. Areas to the east should continue to monitor as an isolated strong to severe thunderstorm is possible and if the trough and front pushes into the area a bit more quickly with heating over the area, more numerous strong to severe thunderstorms could occur in this area. As we get past sunset, the situation could evolve into more garden variety thunderstorms but could pose a flood threat to urban and poor drainage areas if the activity slows and tracks/trains over the same area and this will be monitored as well.

SKYWARN Activation with Ops at NWS Taunton will commence at Noon today. This will be the last coordination message on activity for Sunday. If a thunderstorm threat for flooding or possibly isolated severe weather evolves into Monday, another coordination message for Monday may be issued. Below is the NWS Taunton Special Weather Statement, Hazardous Weather Outlook, and SPC Day-1 Convective Outlook:
