Re: Long Duration Winter Storm Today through Tuesday


Updates are highlighted in blue.


Situation Overview

The National Weather Service (NWS) has provided the following forecast for tonight into Tuesday morning:

·        Rain will change to snow late this afternoon through tonight from North to South (with changeover occurring on Cape Cod toward daybreak). Snowfall will be heavy at times late tonight into Tuesday morning.

·        Bands of heavy snow possible across much of eastern MA, especially on Tuesday from 4- 10 AM. Localized snowfall rates of 1-2"/hour possible.

·        Wind gusts of 30- 45 mph will continue into Tuesday along coastal areas, with the highest gusts over Cape Ann, outer Cape Cod, and the coastal waters off eastern MA. Winds are expected to diminish Tuesday afternoon.


In terms of snow accumulations, expect additional accumulations after 7 PM tonight through Tuesday morning; in general, 2-4 inches across much of the region, but up to 4-8 inches possible across eastern MA, especially from Boston north through Essex County and the Merrimack Valley. 

·        Moderate confidence in additional snowfall of 4 inches for eastern MA; lower risk for up to 8 inches, especially north of Boston.

·        If storm tracks a bit further east than expected, lower snowfall amounts would be realized for eastern MA with max snowfall around 4 inches.

·        If storm tracks further west, 4-8 inches would impact a larger portion of eastern MA and possibly into northern RI, with locally higher amounts north of Boston.


There still remains some uncertainty with regard to:

·        Exact timing of transition from rain back to snow may be off by a few hours which could impact snowfall amounts.

·        Snowfall rates late tonight into Tuesday morning in eastern MA depending on the track of the storm. If the storm tracks a bit further east, less snowfall will occur.


Warnings, Watches and Advisories

·        Winter Storm Warnings expanded to include coastal Essex, Suffolk, Norfolk and Plymouth counties.

·        Winter Weather Advisory issued for Cape Cod.

·        Wind Storm Warnings converted to Advisories for western and northern MA west of I-495.


Potential Hazards/ Impacts


Heavy Snow

·        Hazardous travel conditions on all surfaces, treated or untreated; avoid travel if possible.

·        Significant impact to Tuesday morning commute.


Strong Wind Gusts

·        Loose objects may become airborne; isolated tree damage.
