[Weather] [2019.02.05 AM NWS Briefing] Icing Threat Wednesday Evening into Thursday Morning

[BOX Operations - NOAA Service Account]

Good morning,

A wintry mix of freezing rain and/or sleet is likely Wednesday evening into
Thursday. Please see the attached image with respect to forecast ice
accretion amounts.

*Our greatest concern is the potential for icing during the Thursday AM
commute, especially across interior areas of Southern New England away from
the immediate coast*. With any icing, untreated roadways will become slick
resulting in hazardous travel conditions. In addition, there's a low risk
of downed limbs due to the weight of ice with the potential for isolated
power outages.

*What / Where / When ...*

   - Initially sleet mixing with and changing over to freezing rain
      - Across the interior away from the immediate Southern New England
      shoreline, the largest ice accretion amounts are forecast for the
      Berkshires and Worcester Hills.
      - Developing Wednesday evening and continuing into Thursday, through
      the Thursday AM commute.
      - With any freezing rain, untreated surfaces will become icy
      resulting in hazardous travel conditions.

*Uncertainty ...*

   - Challenges in forecasting the exact timing of precipitation-types
   makes it difficult to be certain to a high degree of sleet accumulation and
   ice accretion amounts, as well as if and when the transition to rain will
   occur.
   - While there is high confidence concerning wintry precipitation for
   Wednesday evening into Thursday, confidence is lower with respect to exact
   outcomes and subsequent impacts.
   - Expect future refinements to the forecast.

Should you have any questions, comments and/or concerns, please don't
hesitate to reach out to us.

Respectfully,

Benjamin Sipprell
