Storm Coordination Message #1 – Sunday Evening 11/15/20-Early Monday Morning 11/16/20 – Strong to Damaging Wind Potential
Hello to all…
..Strong cold front will make its way through Southern New England and bring with it the potential for strong to damaging winds and a convective fine line of showers and thunderstorms which could enhance the wind damage potential if this line develops as models indicate. The Storm Prediction Center (SPC) has the region in a general thunderstorm risk with a potential upgrade possible in future outlooks..
..A Wind Advisory is now in effect from 5 PM Sunday until 1 AM Monday for all of Rhode Island, Cape Cod and the Islands and Southern Worcester, Central and Southeast Middlesex, Essex, Suffolk, Norfolk, Bristol, and Plymouth Counties of Massachusetts for sustained winds of 20-30 MPH with gusts to 50 MPH. Other areas could see wind gusts to 40-45 MPH with higher gusts and could mean expansion of wind advisories in future updates. These winds will cause scattered pockets of tree and wire damage and power outages..
..SKYWARN Self-Activation will monitor the strong to damaging wind and severe weather potential for Sunday Afternoon through early Monday Morning..
A strong cold front will have the potential to bring general strong to damaging winds with a possible enhanced setup for damaging winds in a fine line of showers and thunderstorms that potentially develops and sweeps through the region. The headlines depict the current thinking. Key factors include:
1.) The environment can be characterized by a low instability/high shear environment. If the jet dynamics and wind shear aloft can compensate for lower instability, the wind damage threat from a convective line of showers and thunderstorms increases.
2.) If instability is higher than projected with the current projections for strong to damaging winds aloft, that would also increase the threat for damaging winds in the region.
SKYWARN Self-Activation will monitor the strong to damaging wind and severe weather potential for Sunday Afternoon through early Monday Morning. Another coordination message will be posted by 1000 AM Sunday Morning.
