Severe Weather Coordination Message #2 – Tuesday August 11th Severe Weather Potential

Hello to all..

..Heavy rainfall with embedded thunderstorms and some strong winds up to or slightly over 40 MPH will continue through Midday in western parts of Southern New England and through early afternoon in eastern areas ahead of a warm front. After this moves through, isolated to scattered strong to severe thunderstorms are possible across much of Southern New England with heavy rainfall and urban and poor drainage flooding, strong to damaging winds as the main threats. Cannot rule out an isolated brief tornado if enough destabilization occurs and can tap into the strong wind shear fields and turning in the atmosphere..
..SKYWARN Self-Activation will monitor conditions through Noon today. SKYWARN Activation with Ops at NWS Taunton will start around or shortly after Noon today for the severe weather potential..

At 1025 AM, Doppler Radar showed rain, heavy at times with embedded thunderstorms moving through Southern New England. The rain is moving along and should be out of western areas by Noon and eastern areas by around 2 PM this afternoon. Rainfall amounts of 1-1.5″ with higher amounts are possible with this initial rainfall. After this rainfall, a cold front will be approaching Southern New England. Shear values may weaken a bit with time but still remain fairly strong with some turning in the atmosphere noted. Any cloud breaks and sunshine after the rainfall that moves through the area will set the stage for isolated to scattered strong to severe thunderstorms with heavy rainfall and urban and poor drainage flooding and strong to damaging winds as the main threats. An isolated tornado cannot be ruled out if enough destabilization occurs and can tap into the strong wind shear fields and turning in the atmosphere.

SKYWARN Self-Activation will monitor conditions through Noon today. SKYWARN Activation with Ops at NWS Taunton will start around or shortly after Noon today for the severe weather potential. This will be the last coordination message on today’s severe weather potential. Below is the NWS Taunton Hazardous Weather Outlook and SPC Day-1 Convective Outlook:
