Severe Weather Coordination Message #2 – Tuesday August 25th 2015 – Severe Weather Potential
Hello to all..
..Isolated to Scattered Strong to Severe Thunderstorms remain possible to likely 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 from late Tuesday Morning through Tuesday Evening. The Storm Prediction Center (SPC) continues a marginal risk for severe weather across much of Southern New England..
..Morning round of strong thunderstorms affected Northwest Massachusetts into Southern New Hampshire with heavy rainfall. Morning activity didn’t occur in Southeast New England as activity was further offshore than modeled..
..Degree of severe weather potential will hinge on amount of clearing over Southern New England. Clearing is expected to occur from southwest to northeast across Southern New England which will increase instability with sufficiently strong winds aloft for isolated to scattered strong to severe thunderstorm activity depending on the timing of the cold front..
..SKYWARN Activation with Ops at NWS Taunton will commence at 11 AM Tuesday Morning through Tuesday Evening..
Tuesday has been the signature day for potential severe weather events and this Tuesday looks like no exception. SKYWARN Self-Activation monitored a round of strong thunderstorms that affected Franklin County Massachusetts and went into Southern New Hampshire. These thunderstorms resulted in 2-3″ of rainfall in some areas with one isolated tree and wire damage report in Hawley Mass and some street/basement flooding issues. No activity occurred in Southeast New England as strong thunderstorms stayed well offshore of that area.
Isolated to Scattered Strong to Severe Thunderstorms will be possible to likely ahead of a slow moving cold front which will bring cooler and lesser humid air to the region. The threat will be continent on the amount of clearing and satellite imagery shows clearing should take place across Southern New England from southwest to northeast. The threat is also contingent on the timing of the slow moving cold front into our area. The clearing and current expected timing of the cold front should allow for sufficient destabilization with strong winds aloft to result in isolated to scattered strong to severe thunderstorms with strong to damaging winds, hail, frequent lightning and heavy rainfall with urban and poor drainage flooding as the main threats.
SKYWARN Activation with Ops at NWS Taunton will commence at 11 AM EDT Tuesday. This will be the last coordination message on Tuesday’s severe weather potential. Below is the NWS Taunton Hazardous Weather Outlook and SPC Day-1 Convective Outlook:
