- Most of MA, RI & CT will receive 2-4 inches of snow before snow briefly changes over to rain and/or a wintry mix before ending around midnight or shortly thereafter
- Western & northern Massachusetts along with northwest CT will likely receive the highest totals of 4 to 8 inches while the south coast of MA and RI likely only receive 1-3 inches before changing to rain before ending. This includes Cape Cod and the Islands.
Forecast Confidence ...
- Still some uncertainty on the exact timing of the changeover from snow to rain or a brief wintry mix. Therefore three snowfall maps are included to express this uncertainty, StormTotalSnow (most likely snowfall), SnowAmt10PrcntilISC (low end amount) and SnowAmt90PrcntilISC (high end amount). Given the very cold airmass over the region late today and continuing overnight with morning lows Saturday in the single digits and teens, this may delay the changeover and result in an hour or two of additional snowfall. Therefore our most likely snowfall map is very close to the high end snow map.
Given the event is still about 24 hours away the exact timing may change by an hour or two with later forecasts along with snow amounts increasing or decreasing by an inch or two. Thus stay tuned to later forecasts and discussions. The next email briefing will be issued around 4 am to 5 am Saturday.
