[Weather] [2020-03-23 AM] NWS Boston EM Briefing for Coastal Storm Monday into Tuesday Morning

[BOX Operations - NOAA Service Account]

Good morning everyone,

Here is the latest thinking about the coastal storm which will pass
southeast of New England today into early Tuesday. It will bring snow to
much of the area this afternoon before a change to rain Monday night. This
is expected to be a minor snowfall event, with the exception of  the higher
elevations of western and central MA, where as much as 8 inches of snow is
possible.

*NEW:*

   - Northwest Middlesex County changed from a Winter Weather Advisory to a
   Winter Storm Warning

*What/Where/When:*

   - Snow develops from west to east across much of southern New England
   Monday afternoon, except near the South Coast, Cape Cod, and the Islands
   where mainly rain is expected.
   - Snow is expected to be heavy at times late Monday afternoon into
   evening, especially in the Berkshires and northern Worcester Hills. Heavy
   snowfall rates could lead to snow-packed roads and difficult travel.
   - Snow mixes with and changes over to rain from south to north. The
   higher elevations of northern Worcester County and the Berkshires are
   expected to remain mostly snow.
   - The consistency of the snow will be heavy and wet.

*Uncertainty:*

   - Snow amounts will be highly elevation-dependent, leading to
   potentially significant countywide differences in snow totals.
      - Portions of northwest Hartford County may see 3-5" with quickly
      diminishing amounts to the south and east.
   - If the coastal storm passes farther offshore, snowfall totals will be
   less, especially across the interior.
   - Conversely, if the storm tracks closer to southern New England, there
   would be less snow across most of the region, since the higher
   accumulations would shift to the northwest of MA.
