Storm Coordination Message #1 – Tuesday 12/17/19 Winter Storm Potential

Hello to all…

..Snow and Ice will have a significant impact on the Tuesday Morning Commute across Southern New England. Ice accretion may be thick enough to result in isolated pockets of tree and wire damage and isolated power outages if ice accretion values are thick enough..
..A Winter Weather Advisory is in effect from 1 AM to 7 PM Tuesday for Franklin, Hampshire, Hampden, Worcester, and North-Central Middlesex Counties of Massachusetts for 3-5 inches of snow and a light glaze of ice..
..A Winter Weather Advisory is in effect from 1 AM to 7 PM Tuesday for Northern Connecticut, and Northwest Providence County Rhode Island for 2-4″ of snow and up to two-tenths of an inch of ice. In this area, ice accretion may be thick enough to result in isolated pockets of tree and wire damage and isolated power outages depending on the ice thickness..
..A Winter Weather Advisory is in effect 1 AM to 1 PM Tuesday for the remainder of Rhode Island, Eastern Essex, Southeast Middlesex, Norfolk, Bristol and Plymouth Counties of Massachusetts for 1-3″ of snow and a light glaze of ice..
..SKYWARN Self-Activation with Amateur Radio call-up nets will monitor this winter storm for Tuesday..

Another winter storm is slated to impact Southern New England for Tuesday. The headlines depict the current thinking. Key factors of this storm include:

1.) The morning commute will be significantly impacted by snow and ice and the heaviest accumulating snow will fall during the commute. This will result in slippery road conditions and slowed travel during this period. Allow plenty of time to get to your destination or delay travel until later in the day.
2.) The evening commute could have some impacts in western and central New England but not as bad as the morning commute.
3.) Ice accumulations across Northern Connecticut and Northwest Rhode Island could cause some isolated pockets of tree and wire damage and isolated power outages if the higher end ice thicknesses are realized and this will be monitored.
4.) The snow versus snow/mix to freezing rain has oscillated north and south based on the various models. This will ultimately dictate snow and ice amounts in the region and will be monitored.
5.) Models have trended a bit heavier with the precipitation which has led to bumping up the snow and ice amounts slightly in the region and this will be monitored.

SKYWARN Self-Activation with Amateur Radio call-up nets will monitor this winter storm for Tuesday. If time allows another coordination message will be posted Tuesday Morning but given we will be in operations mode, this may be the only message on this storm event.
