A moderate, quick hitting snowstorm will affect the region late Saturday Afternoon through early Sunday Morning. The headlines depict the current thinking. The biggest change is the addition of a Winter Weather Advisory for South Coastal Massachusetts and Rhode island including Cape Cod. Key factors remain as follows:

1.) Precipitation will start from west to east with slightly later timing between 5 to 7 PM and taper off between 10 PM to 1 AM from west to east.
2.) If heavier snowfall rates of 1″ per hour last longer than expected in the warning areas, slightly higher snowfall amounts would occur. Conversely, if these snowfall rates don’t last as long as currently predicted, slightly lesser snowfall amounts could occur.
3.) In advisory areas, if 1″ per hour snowfall rates last longer than expected and/or any changeover in precipitation doesn’t occur during heaviest precipitation, slightly higher snowfall amounts could occur. If those snowfall rates don’t last as long expected or a changeover in precipitation occurs a bit earlier than expected, slightly less snowfall amounts would occur. Due to the initial cold air, the Winter Weather Advisory was expanded to South Coastal Massachusetts and Rhode Island including Cape Cod.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets will occur Saturday Evening. Amateur Radio Operators who check into the Western Massachusetts ARES and Emergency Nets on Sunday Morning are asked to provide final snowfall measurements if not provided and totals aren’t final in any Amateur Radio SKYWARN Call-Up Nets completed by late Saturday Evening. This will be the last coordination message as we move into operations mode.
