A moderate, quick hitting snowstorm will affect the region late Saturday Afternoon through early Sunday Morning. The headlines depict the current thinking. Key factors include:

1.) Precipitation will start from west to east between 3 to 6 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.

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. Another coordination message will be posted by 10 AM Saturday Morning.
