[Weather] [2026.01.18 AM] NWS Boston EM Briefing: Plowable Snow Today & Tonight

[BOX Operations - NOAA Service Account]

Good morning everyone...

Winter Weather Advisories have been expanded to all southern New England
(except Nantucket) and snowfall amounts have been increased. Total snow
accumulations of 2-5" are expected for western MA and CT with 3 to 6"
across eastern MA/RI with localized 7" amounts possible. Rain mixed with
the snow at times may cut down on totals across portions of Cape Cod and
especially Nantucket where much of this may fall as rain.

Periods of mainly light snow develop this morning and continue at times
this afternoon...but a lull in the activity is possible especially north of
I-90. The steadiest/heaviest of the snow is expected late this afternoon
and especially tonight. Snowfall rates of 1"+ per hour are possible in the
5 pm to 1 am time frame...particularly across eastern MA/RI. While the
steady snow will be over by daybreak Monday...some snow showers may linger
into the Monday morning commute especially across eastern MA. The biggest
uncertainty with this forecast revolves around whether or not we see a
heavier swath of 5-7" of snow and where exactly that sets up. Right now we
would favor eastern MA/RI as the best chance for that to occur.

We have included an updated one-pager along with our snowfall
graphic/timeline. In addition...we also have included  a probability table
for specific locations in our region to see snowfall rates approach 1" per
hour. This is just meant to give an idea of when the heaviest snowfall
rates/impacts will occur and you can see how this indicates from 5 pm
through 1 am Monday. Lastly...there is a lot of black ice out there this
morning  so that may be an issue for folks trying to get out before the
snow actually starts!

Thank You!

Meteorologist: Hayden Frank
