Good afternoon!

Here is a breakdown of our storm.

Timing

Snow, sleet, freezing rain, and rain showers will be around from this evening until tomorrow evening. Then widespread precipitation moves in tomorrow evening. The heaviest rain is tomorrow night into Tuesday morning, and tapers off into scattered showers throughout the day. Precipitation is mainly all rain for most by tomorrow midday, with areas well inland staying on a mixed precipitation that could include snow, sleet, freezing rain, and rain. Precipitation should finally let up by tomorrow evening.

Impacts

The heaviest rain falls in eastern areas, and as such, a flood watch has been issued for eastern Massachusetts with urban areas, poor drainage, and  low lying areas at highest risk; some small streams could also flood.

Winds will also be strong – northeast 20-40 mph with gusts 40-70 possible, and wind advisories have been issued for the Berkshires, Litchfield Hills, and southern Green Mountains, and may be needed elsewhere; a high wind watch is also in effect for Cape Ann of northeast MA as well as coastal southeast MA (Cape Cod and the Islands have been upgraded to a warning, along with coastal RI and CT). Gustiest winds will be at the coast.

Snow, sleet, and freezing rain may cause travel difficulties. Freezing rain in particular will cause problems; ice accretion up to four tenths of an inch may lead to minor damage to trees and some power outages, in addition to very hazardous travel.

 

Stay safe!
