[Weather] [2018.01.16 PM NWS Brief] 2 Systems To Monitor Through This Weekend

[BOX Operations - NOAA Service Account]

Good afternoon everyone,

We continue to monitor two winter systems, one for early Friday, the other
for the weekend. * Note that the single snowfall forecast attached to this
email is for the Friday morning system only.  The full set of briefing
slides is for the weekend storm.*

*Friday:*

   - Light snow begins between 1AM and 7AM Friday, impacting the commute
   for most of Southern New England.
   - Snowfall rates of less than 1 inch/hour are expected, with
   accumulations up to 3 inches across western MA, decreasing closer to the
   coastlines.  (See attached snowfall map)
   - Snow changes to rain especially across the coastal plain of MA/RI
   during the afternoon.
   - Some untreated road surfaces may be covered.

*Saturday night - Sunday night:*
See the slides attached to this email.  Heavy snow changing to an icy mix
and then to rain, mainly across the southeast, is expected, along with a
risk for strong winds, inland and coastal flooding.  This storm is likely
to be followed by a flash freeze beginning late day Sunday into Sunday
night, with bitter cold air into Monday.

Overall confidence is high for a moderate to high impact storm, but
confidence in exact details and timing remains low at this time. We will
continue to update into the weekend.
