Storm Coordination Message #2 – Wednesday 10/7/20 Strong to Damaging Wind and Severe Weather Potential
Hello to all…
..A powerful cold front will bring strong to damaging winds and even the threat for Isolated to Scattered strong to severe thunderstorms given an intensifying storm system, strong winds aloft and very cold temperatures aloft when compared to surface temperatures provided thunderstorms can form with limited moisture profiles. Strong to damaging winds, hail and lightning would be the primary threats with any strong to severe thunderstorms.
..The Storm Prediction Center, SPC, has expanded the marginal risk for severe weather across much of Southern New England for this Wednesday Afternoon and Evening. The timeframe for any strong to severe thunderstorms would be from 2-8 PM this Wednesday Afternoon and Evening..
..A High Wind Warning remains in effect through 2 AM Thursday for Cape Cod and the Islands for sustained winds of 20-30 MPH with gusts to 60 MPH. A High Wind Warning is now in effect from 2 PM Wednesday Afternoon to 2 AM Wednesday Morning for Franklin, Hampden, Hampshire, Worcester, Essex, Middlesex, Suffolk and Norfolk Counties of Massachusetts for sustained winds of 15-20 MPH with gusts of 60 MPH. A Wind Advisory is now in effect for Northern Connecticut, Rhode Island and Southeast Massachusetts from 2 PM Wednesday Afternoon through 2 AM Thursday Morning for sustained winds of 10-20 MPH with gusts to 50-55 MPH. These winds will have the potential for isolated to scattered pockets of tree and wire damage and power outages..
..SKYWARN Self-Activation will monitor the strong to severe thunderstorm and wind damage potential for Wednesday. This will be the last coordination message as we shift into operations mode..
A powerful cold front will bring strong to damaging winds and even the threat of isolated to scattered strong to severe thunderstorms for much of Southern New England and the headlines depict the current thinking. At 1135 AM, Doppler Radar showed an area of rain and some embedded heavier rain associated with the cold front that will bring the strong to damaging winds and the threat for low topped convective showers and isolated to scattered strong to severe thunderstorms which will have the ability to bring stronger winds down to the surface as well as the potential for hail even if any of the convection has little to no lightning. This will be monitored throughout the day.
SKYWARN Self-Activation will monitor the strong to severe thunderstorm and wind damage potential for Wednesday. This will be the last coordination message as we shift into operations mode.
