Storm Coordination Message #1 – Late Tuesday Night 9/29/20 Through Midday Wednesday 9/30/20 Strong Wind & Heavy Rainfall Potential

Hello to all…

..Beneficial rainfall expected overnight into late Wednesday Morning but it will also be accompanied by strong to damaging winds over portions of Southern New England..
..A Wind Advisory is now in effect from Midnight tonight to 1 PM Wednesday for all of the NWS Boston Norton Coverage area except for Franklin, Hampshire and Western Hampden Counties of Massachusetts for sustained winds of 15-25 MPH and gusts of 40-50 MPH. Isolated to scattered higher wind gusts possible in any fine line of convective showers and thunderstorms bring stronger winds down to the surface. These winds will cause isolated to scattered pockets of tree and wire damage and isolated power outages..
..Rainfall amounts of 1-2″ with isolated higher amounts are likely north and west of Interstate-495 through Northwest Rhode Island and Northern Connecticut. Amounts of 0.25-1.00″ are possible east of I-495..
..SKYWARN Self-Activation will monitor for wind gust measurements, wind damage and rainfall reports of 1″ or more from this storm system..

After an extremely quiet period of weather across Southern New England during the month of September, a strong storm system will bring beneficial rainfall to Southern New England but it will also bring strong to damaging winds to portions of Southern New England. The headlines depict the current thinking. Key factors include:

1.) The fine line of convective showers and possible thunderstorms and their ability to bring the strongest winds down to the surface.
2.) The potential for the intensifying storm system for strong winds to reach the surface. Some models have some stronger winds reaching the surface if enough mixing of the winds can occur. This aspect will be monitored.

SKYWARN Self-Activation will monitor for wind gust measurements, wind damage and rainfall reports of 1″ or more from this storm system. This will be the only coordination message on this storm as we shift into operations mode unless a significant change to the situation occurs and time allows for an update.

Hello to all…

..Hurricane Teddy will pass well offshore of Southern New England but the gradient between Teddy and High Pressure over Southern New England will bring strong to damaging winds for Cape Cod and the Islands with strong wind gusts over East and South Coastal Massachusetts along with high surf and the potential for minor coastal flooding at the time of high tide Tuesday Afternoon. While winds will be less in the interior, fire weather will be a concern due to dry conditions, low humidity and breezy conditions..

A Wind Advisory is in effect for Cape Cod and Martha’s Vineyard from 9 AM to 8 PM Tuesday for sustained winds of 20-30 MPH with gusts to 50-55 MPH. A Wind Advisory is in effect for Eastern and Plymouth Counties for sustained winds of 20-30 MPH with gusts of 40-50 MPH. Other coastal areas could see wind gusts near 40 MPH today. These winds will cause isolated to scattered pockets of tree and wire damage and isolated power outages..
