Severe Weather Coordination Message #1 – Tuesday August 25th, 2015 Severe Weather Potential

Hello to all..

..Isolated to Scattered Strong to Severe Thunderstorms possible across much of Southern New England with strong to damaging winds, hail, frequent lightning and heavy rainfall with urban and poor drainage flooding as the main threats..
..There could be two rounds of activity, one round in the morning in Southeastern New England and one affecting Western, Central and interior Northeast Massachusetts, Northwest Rhode Island and Connecticut in the afternoon and early evening. The Storm Prediction Center (SPC) has placed much of Southern New England in a marginal risk for severe weather..
..At this time, SKYWARN Self-Activation will monitor any morning strong to severe thunderstorm activity. SKYWARN Activation with Ops at NWS Taunton are likely anytime after 1 PM EDT Tuesday..

Tuesday has been the signature day for potential severe weather events and this Tuesday looks like no exception. Isolated to Scattered Strong to Severe Thunderstorms will be possible ahead of a slow moving cold front which will bring cooler and lesser humid air to the region. At this time, two rounds of isolated to scattered strong to severe thunderstorms could affect the region. The first round potentially over Southeast New England and the second round across much of Southern New England north and west of a Boston to Providence line and weakening as it approaches coastal Southern New England. Strong to damaging winds, hail, frequent lightning and heavy rainfall with urban and poor drainage flooding are the main threats. SPC has placed much of Southern New England in a marginal risk for severe weather.

Key items regarding the severe weather potential for this Tuesday includes:
1.) Amount of morning convection and its ultimate intensity.
2.) Amount of clearing behind any morning convection that affects the region.
3.) Timing of the cold front through Southern New England.

At this time, SKYWARN Self-Activation will monitor any morning strong to severe thunderstorm activity. SKYWARN Activation with Ops at NWS Taunton are likely anytime after 1 PM EDT Tuesday. This will be reviewed again on Tuesday Morning. Another coordination message, possibly a shortened one depending on the extent of any morning convection, will be posted by 9 AM Tuesday Morning. Below is the NWS Taunton Hazardous Weather Outlook and SPC Day-2 Convective Outlook:
