Storm Coordination Message #1 – Monday 12/14/20 Light Snowfall Event and Wednesday Night 12/16/20-Thursday 12/17/20 Major Winter Storm Potential

Hello to all…

..A storm system will approach Southern New England tomorrow ushering cold air and a period of light snow Monday Afternoon into early evening. Amounts over Southern New England will range from a Coating to 2″. Will watch Southeast New England for isolated higher amounts of greater than 2″ if the precipitation is heavy enough and conditions are sufficiently cold at the surface to allow for accumulation..
..A much more significant and potentially major winter storm will affect Southern New England late Wednesday Night through Thursday with the potential for significant snowfall across Southern New England as well as the potential for strong winds and coastal flooding. All of this will be contingent on the track, speed and intensity of the system. Models have continued to shown this potential for several days but the details of the storm intensity, snow amounts, any cutoff in precipitation for northwest areas and whether any mixed precipitation occurs along the extreme south coast of New England is not certain and will be defined in the coming days..
..SKYWARN Self-Activation will monitor the light snowfall for Monday and the more significant major winter storm for Wednesday Night into Thursday. Another coordination message will be posted by 10 AM Monday Morning. Below is the NWS Boston/Norton Area Forecast Discussion, Enhanced Hazardous Weather Outlook, and snowfall map..
