[Weather] [2020-03-22 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 Late Monday into Tuesday. It will bring snow to
much of the area Monday afternoon before a change to rain Monday night.

The key takeaway is that this is expected to be a minor snowfall event,
with the exception of  the higher elevations of western and central
Massachusetts, where as much as 8 inches of snow is possible.

Changes:

   - Increased snowfall amounts in the high elevations
   - Winter Storm Watch issued for the Berkshires and northern Worcester
   Hills

*What/Where/When:*

   - Snow develops across much of southern New England Monday afternoon,
   except near the South Coast, Cape Cod, and the Islands where mainly rain is
   expected.
   - Snow should be briefly heavy late Monday afternoon and early Monday
   evening before changing to rain from south to north. Only the higher
   elevations of northern Worcester County and near the Berkshires are
   expected to remain all snow.
   - Accumulations of a slushy inch or two are expected in the Providence
   and Boston areas,  2-4" in the Hartford/Springfield area and near the I-495
   corridor in northeast Massachusetts, and 5-8" in the higher elevations in
   the Berkshires and in northern Worcester County.
   - The consistency of the snow will be heavy and wet in all areas.


*Uncertainty:*

   - 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 Massachusetts.


Thanks,
Bryce Williams and Bill Babcock
