Storm Coordination Message #3 – Monday 3/23/20-Tuesday Morning 3/24/20 Winter Storm Potential

Hello to all…

..Winter makes a brief return with the potential for heavy wet snow accumulation in Western and Central Massachusetts particularly in the higher elevations with lighter snow accumulations in other parts of Southern New England before a change to rain as a coastal storm moves through the region..
..A Winter Storm Warning remains in effect 4 AM Tuesday Morning for Western Franklin, Northern Worcester, Western Hampshire and Western Hampden Counties of Massachusetts for 4-8″ of snow. The snow will be heavy and wet and this could lead to isolated pockets of tree and wire damage and isolated power outages and the evening commute would be most adversely affected with slippery road conditions..
..A Winter Storm Warning is now in effect through 4 AM Tuesday Morning for Northern Middlesex Counties of Massachusetts for 4-8″ of snow. The snow will be heavy and wet and this could lead to isolated pockets of tree and wire damage and isolated power outages and the evening commute would be most adversely affected with slippery road conditions..
..A Winter Weather Advisory remains in effect through 4 AM Tuesday Morning for Eastern Hampshire, Eastern Franklin, Eastern Hampden and Southern Worcester Counties for 2-5″ of snow. The evening commute would be most adversely affected with slippery road conditions. Areas of Northwest North-Central Connecticut closest to the Mass state border and the Litchfield County Connecticut line could see similar amounts of snow..
..Portions of Northwest and North-Central Connecticut furthest away from the Massachusetts state line and the Litchfield County Connecticut line into parts of interior Massachusetts may see a coating to 2″ of snow with this system with a few slick spots before it changes to rain. Eastern New England particularly south and east of I-495 through Rhode Island and Southeast Massachusetts will see mostly rain from this system..
..SKYWARN Self Activation with Amateur Radio Call-Up Nets likely Monday Afternoon and Evening across the Winter Storm Warning and Winter Weather Advisory areas most likely starting around or after 5 PM through late evening..

A coastal storm will bring a touch of winter to portions of interior Southern New England for Monday. The headlines depict the current thinking and have been updated based on the current set of weather models. Key factors for this storm remain the following:

1.) A track closer to the coast will bring warmer air into the region and knock down snow accumulations and move the heavier snow into Northern New England. A track further offshore would mean less snow in interior Southern New England and still result in mostly rain in Eastern New England.
2.) How much cold air is locked in as the storm system moves through the region assuming the current track remains in place.
3.) How wet and heavy the snow is particularly in the Winter Storm Warning area and northern most portions of the Winter Weather Advisory area, closest to the Winter Storm Warning area.

SKYWARN Self Activation with Amateur Radio Call-Up Nets likely Monday Afternoon and Evening across the Winter Storm Watch area and any Winter Weather Advisory areas. This will likely be the last coordination message on this storm unless a significant change to the situation occurs and time allows for an update.
