[Weather] [2020.01.07 PM] NWS Boston EM Briefing: Accumulating Snow Overnight Across Southeast New England

[BOX Operations - NOAA Service Account]

Good afternoon everyone,

The only real change with this afternoon's update is a Wind Advisory which
has been issued for Cape Cod, the Islands, and portions of western/central
MA for Wednesday afternoon into Wednesday night (see attached).

A Winter Weather Advisory remains in effect for south coastal
Massachusetts, Cape Cod and the Islands for between 2 and 4 inches of snow
overnight.  See the attached expected Snow Accumulations/Winter Weather
Headlines.

*WHAT/WHERE:*
- Winter Weather Advisory issued for 2 to 4 inches of snow overnight across
south coastal MA as well as Cape Cod and the Islands.
- Lower snowfall totals are anticipated further northwest, with a coating
to 2 inches expected in the Boston to Providence corridor.

*WHEN:*
*- *The snow will begin after 10 or 11 pm tonight with the accumulating
snow pretty much over by 5 am Wednesday morning.
- The snow may begin as a period of rain across the outer-Cape/Nantucket,
but will change over to snow. Snowfall rates may reach 1 inch per hour
across far southeast New England for a short time overnight.
- Threat for accumulating snow will have pretty much ended by the start of
the Wednesday morning commute, but untreated roads may be snow covered and
slippery.

*UNCERTAINTY:*
- High confidence that the heaviest snowfall will occur across far
southeast New England, but exact snowfall amounts remain uncertain.
- Current indications are for 2 to 4 inches of snow across south coastal
MA, Cape Cod and the Islands.  A coating to 2 inches of snow is expected
further northwest into the Boston to Providence corridor.
- If the storm tracks a bit further northwest, the low risk exists for 2 to
4 inches of snow further northwest across most of RI and most of  SE MA
with localized 5 inch amounts possible near the Cape Cod Canal
- If the storm tracks a bit further to the southeast, any threat for
accumulating snow would be confined to Cape Cod and the Islands and would
be just an inch or two.

Please let us know if you have any questions or concerns!

Thank You
