[Weather] [2018.01.16 AM NWS Briefing] 2 Systems To Monitor Through This Weekend

[BOX Operations - NOAA Service Account]

Good morning, all:

   - Light snow will overspread from west to east during the morning
   commute.  Snowfall rates should generally be light, at or below an inch an
   hour.
   - The light snow will continue, with accumulations of up to 3 inches,
   ending during the late afternoon and evening.  Highest totals across
   northern and western MA/CT, lowest totals across RI and eastern MA.
   - A change to rain is expected across the coastal plains of MA and RI
   during mid day into the afternoon.
   - Some light accumulations possible on untreated surfaces. A preliminary
   graphic is attached.

*Saturday night - Sunday:*

   - Low confidence in the details at this time.
   - Precipitation will begin late Saturday evening, overspreading the
   entire area Saturday night into mid day Sunday.
   - Tricky precipitation type forecast, potentially starting as period of
   heavy, wet snow, changing to ice then to heavy rain into the day on Sunday.
   Timing of these changes will likely take a couple more days to resolve well.
   - There is a risk for a significant, plow-able snowfall and/or icing.
   - There is also the low-moderate risk for some areal and river flooding
   given the snow to rain transition.
   - We are monitoring the risk of coastal flooding along the South Coast.
   The period of concern is short, the potential is for minor flooding at
   worst, and the risk remains low.

We will continue to update you as this week progresses and confidence
increases. If you have any questions or concerns beyond the scope of this
briefing, don't hesitate to reach out to us via any of the means below.
