SITUATIONAL AWARENESS STATEMENT #3
Date: December 1, 2019
Time: 8:00 AM
Re: Long Duration Winter Storm Today through Tuesday
Updates are highlighted in blue.
The National Weather Service (NWS) is forecasting a high impact winter storm beginning this
later this afternoon into Tuesday.Today into early Monday the snow will begin in
western MA between 2- 3 PM; central MA between 3- 4 PM; and eastern MA between 4- 6 PM. Snow will become heavy at times (1"/hour) shortly after onset and will continue in the
late afternoon and evening hours. As warmer air intrudes aloft, precipitation changes to sleet, then to a sleet/snow mix in northern MA, and to plain rain in southeast MA for the overnight hours. By daybreak Monday, snow/sleet accumulations of 6-8" possible
in western and northern MA with approximately 4-6" in Springfield and interior Essex County, with 2-5" elsewhere, except less than an inch on Cape Cod/Islands and near the immediate coast in southeast MA.
Early in the morning on Monday, rain will be occurring in much of eastern MA, with a mixed bag elsewhere. However, everything will change back to snow from
west to east. The changeover will reach as far east as northeast MA, and central MA by early to mid afternoon.
It will reach eastern MA (except Cape Cod/Islands) by mid afternoon or late evening.
The snow will likely continue into early Tuesday morning.
Less snow is expected than what occurred on the front end Sunday, but there still could be several inches in some locations. This may be dependent on where localized bands of heavier snow set up.
Storm Total Accumulations
The NWS is expecting a widespread 8 to 12 inches over much of interior MA with as much as a foot possible in the higher Worcester hills and 12 to 17 inches
in the east slopes of the Berkshires. Amounts drop off rapidly as one heads southeast, with 3 to 5 inches in Plymouth and less than an inch on Cape Cod and the Islands.
Confidence is highest in the warning areas of western and northern MA, where greater than 6" of snow in a 12 hour period or 8" in a 24 hour period is likely.
NWS lowest confidence is in southeast sections, particularly along the I-95 corridor.
This could be a situation in which there is a sharp snowfall gradient within the city of Boston, with only a slushy inch or two at the immediate coast to warning criteria amounts in western Suffolk County.
Potential Hazards and Impacts
Hazard travel conditions on all surfaces, treated or untreated; avoid travel if possible.
The snow will be very moisture-laden. This could make for compact snow but it will be heavy to shovel.
Wind gusts will increase to 25-40 mph along the south coast late Sunday night.
Monday into Tuesday, winds will gust to 35-45 mph along coastal areas, with the highest gusts over Cape Ann, outer Cape Cod, and the coastal waters off eastern MA.
Loose objects may become airborne; isolated tree damage.
Storm surges of up to 2 feet are expected, but due to low astronomical tides, only splashover is expected for east coastal MA, including Cape Cod Bay and
Nantucket (with northeast winds). Some pockets of minor coastal flooding cannot be ruled out.
Watches, Advisories, and Warnings
Winter Storm Warning now includes Western Hampden, Western Hampshire, all of Franklin, northern Worcester, and northern/central Middlesex counties in MA.
Winter Weather Advisory now includes Norfolk, eastern Hampden, eastern Hampshire, southern Worcester, Suffolk, southeast Middlesex, and Essex counties in MA.
