[Weather] [2019.02.10 PM] Snow / Sleet / Freezing Rain ... Significant Impacts for the Tuesday PM Commute

[BOX Operations - NOAA Service Account]

Good afternoon,

Little has changed from the previous forecast, but we have issued Winter
Storm Watches for western, central,  and parts of eastern Massachusetts.

Please see the attached slides conveying the anticipated threats while
details concerning impacts and uncertainty are provided below. Please note,
the timing of precip type graphic is an animation.

*New Headlines ...*

   - *WINTER STORM WATCH* issued for western, central, and parts of eastern
   Massachusetts from Tuesday afternoon to Wednesday morning.

*What / Where / When ... *

   - Onset snow transitioning to a wintry mix of mostly sleet with some
   freezing rain across interior Southern New England, transitioning to rain
   along the coast late Tuesday night.
   - Beginning Tuesday afternoon, ending by early to mid-morning Wednesday.
   - Biggest concern are the impacts for the Tuesday afternoon into evening
   commute.
      -  Hazardous travel conditions on roads, especially untreated
      surfaces, and reductions in visibility as a result of potential high
      snowfall rates.

*Uncertainty ... *

   - Still some uncertainty with timing, best scenario would be a later
   onset of snowfall across eastern Massachusetts until after the evening
   commute. The rest of the region looks to be impacted regardless.
   - Potential for snowfall rates of 1-2" an hour during the evening
   commute.
   - Snow and ice amounts could differ across the interior depending on how
   fast warm air moves in overnight.
   - Wednesday morning commute should be okay for the majority of the
   region, but there could still be some lingering icy spots across the
   interior.

We will continue to issue briefings leading up to the event with the latest
forecast information. Should you have any questions, comments and/or
concerns, please don't hesitate to reach out to us.

Thank you,
