Storm Coordination Message #1 – Tuesday Night 1/7/20-Wednesday 1/8/20 Snow and Wind Potential

Hello to all…

..A coastal low will move quickly off the coast of Southern New England near the 40 North/70 West Benchmark and then track into the Canadian Maritimes. It will intensify but east of Southern New England only resulting in a light accumulating plowable snowfall for portions of Southeast Coastal New England..
..A Winter Weather Advisory is in effect from 10 PM Tuesday Evening through 5 AM Wednesday Morning for South Coastal Massachusetts and Cape Cod and the Islands for 2-4″ of snow. Areas fro Boston to Providence to Westerly and to the Advisory area could see a coating to 2″ of snow..
..A Wind Advisory is in effect from 3 PM Wednesday Afternoon through 1 AM Thursday Morning for Northern Connecticut, Cape Cod and the Islands, Franklin, Hampshire, Hampden, and Worcester Counties of Massachusetts for sustained winds of 15-30 MPH with gusts to 50 MPH. Areas outside of the Wind Advisory could see wind gusts of around 40 MPH. These winds could cause isolated pockets of tree and wire damage and isolated power outages..
..SKYWARN Self-Activation will monitor for snowfall reports out of the Winter Weather Advisory area early Wednesday Morning and any measured wind gust and wind damage reports per SKYWARN reporting criteria in the Wind Advisory areas Wednesday mid-afternoon into Thursday Morning..

A coastal low will track near the 40 North/70 West benchmark and then make its way near or over the Canadian Maritimes later Wednesday. The system will come close enough to bring a period of accumulating snow overnight to Southeast Coastal Massachusetts and lighter snowfall in the Boston to Providence to Westerly RI corridor to the advisory area. Strong winds will occur as the system intensifies well east of Southern New England. The headlines depict the current thinking. Key factors for this storm event include:

1.) If the storm track is a bit closer, higher snow amounts of greater than 4″ could occur in the Winter Weather Advisory area with higher amounts in the Boston to Providence to Westerly area. If the storm track is slightly further offshore, lesser snow amounts would occur including in the advisory area.
2.) Strong winds will be expected in the wind advisory area later Wednesday Afternoon into Thursday Morning and areas outside of the advisory area could see wind gusts to around 40 MPH.

SKYWARN Self-Activation will monitor for snowfall reports out of the Winter Weather Advisory area early Wednesday Morning and any measured wind gust and wind damage reports per SKYWARN reporting criteria in the Wind Advisory areas Wednesday mid-afternoon into Thursday Morning. This will likely be the only coordination message for this storm system unless a significant upgrade to the situation occurs and time allows for an update.
