Storm Coordination Message #3 – Sunday AM 2/24/19 Wintry Mix and Late Sunday Night 2/24/19-Monday Evening 2/25/19 Damaging Wind Potential

Hello to all…

..A wintry mix of precipitation is continuing across Western and Northern Massachusetts and will change to rain before ending in these areas. Of greater concern is the development of damaging winds across all of Southern New England late Sunday Night and especially Monday..
..A Winter Weather Advisory is in effect through 10 AM for Franklin, Northern Worcester, Northern Middlesex, Western Hampshire and Western Hampden Counties for light icing. Winter Weather Advisories for other parts of Southern New England has expired with the changeover to rain in these areas..
..A High Wind Warning is now in effect from 10 PM Sunday Evening through 7 PM Monday Evening for Northern Connecticut, Franklin, Hampshire, Hampden and Worcester Counties of Massachusetts and from 3 AM to 7 PM Monday for the rest of the NWS Norton coverage area for sustained winds of 20-40 MPH with gusts to 60-65 MPH and a few isolated wind gusts higher than 65 MPH possible. These winds will be sufficient to cause scattered to potentially numerous pockets of tree and wire damage and scattered to numerous power outages..
..SKYWARN Self-Activation will monitor the wintry mix conditions overnight into Sunday Morning. SKYWARN Self-Activation is likely late Sunday Night into Monday Evening with the potential for Ops at NWS Boston/Norton during the day Monday for the damaging wind potential and the operations plan for Monday’s damaging wind potential will be defined later today..

The headlines depict the current potential with the storm system for late tonight through Sunday Afternoon in terms of the wintry mix and then of more concern is the damaging wind potential for the region late Sunday Night into Monday Evening where High Wind Watches have been upgraded to High Wind Warnings for the entire coverage area. The strongest winds will be during the day on Monday and there is the potential for wind gusts even stronger than the 60-65 MPH gusts in at least isolated areas. Very strong wind fields aloft, good mixing capability to bring the winds down to the surface and a very significant pressure difference between the storm to our northwest that is deepening and the high pressure system will allow for these damaging winds in the region.

SKYWARN Self-Activation will monitor the wintry mix conditions overnight into Sunday Morning. SKYWARN Self-Activation is likely late Sunday Night into Monday Evening with the potential for Ops at NWS Boston/Norton during the day Monday for the damaging wind potential and the operations plan for Monday’s damaging wind potential will be defined later today. Another coordination message will be posted by 10 PM Sunday Evening.
