A storm system will affect portions of interior Southern New England with wintry precipitation with minor coastal flooding possible for East Coastal Massachusetts during the Friday Morning high tide. The headlines depict the current thinking. Key factors include:
1.) While the heaviest snow is expected in Vermont and New Hampshire, accumulating snow will impact portions of interior Massachusetts with the highest amounts in Northwest and North-Central Massachusetts. If deeper cold air can be maintained or continued in parts of interior Massachusetts particularly Northwest and North-Central Massachusetts, then higher snow amounts would be possible. Model trends have been moving in this direction so this will bear close monitoring.
2.) Main concerns are for hazardous travel conditions with little impact to infrastructure unless freezing rain would become more of a predominant form of precipitation and that’s currently not expected at this time but will be monitored.
3.) Minor coastal flooding could impact the Friday Morning high tide cycle and this will bear watching and reporting on coastal flooding during this high tide cycle will likely be needed.
SKYWARN Self-Activation is likely with Amateur Radio Call-Up Nets possible to monitor for snowfall, ice accretion, rainfall, precipitation type and coastal flood reports Thursday Afternoon through Friday Evening. Another coordination message will be posted by 1 PM Thursday Afternoon. Below is the NWS Boston/Norton Winter Weather Advisory Statement & Snow/Ice Accretion Maps:
