A storm system is looking like it will come close enough to Southern New England for accumulating snowfall and a plowable, moderate snowstorm for portions of Southern New England particularly along and south of the Mass Pike. The headlines depict the latest thinking. Key factors for this storm system include:

1.) The track of the storm system as a track further north and west means more snow for the region while a storm track further south and east means less snowfall for the region.
2.) Where any bands of heavier snow may setup including any ocean enhancement with Northeast to North-Northeast flow over Southeastern New England and potentially portions of Northeast Massachusetts.
3.) Model have held the trend of the higher snowfall amounts from the shift in model guidance that was seen starting Saturday Afternoon.
4.) There is some chance for a sleet and rain mix along parts of South Coastal Massachusetts and Rhode Island. The headlines reflect current thinking but could slightly change depending on the storm track, intensity of precipitation and where the rain/snow line ultimately sets up.

SKYWARN Self-Activation with periodic Amateur Radio Call-Up Nets will monitor for snowfall totals around the region starting with the Cape & Islands Weather Net at 600 AM Monday Morning. This will be the last coordination message on this storm event as we shift into operations mode.
