[Weather] [2018.12.16 AM NWS Briefing #3] N/W MA & CT Freezing Rain & Sleet Today Changing to Snow Tonight, Ending Monday Morning

[BOX Operations - NOAA Service Account]

Good morning,

We continue to forecast a wintry mix of snow, sleet and freezing rain
across northern and western portions of Massachusetts and Connecticut for
today into this evening, transitioning to mainly snow this evening,
concluding into Monday morning.

Winter Weather Advisories continue accordingly for the threat of ice
accretion associated with freezing rain.

*What / Where / When ...*

   - Wintry mix of sleet and / or freezing rain across northern and western
   portions of MA and CT
      - Low risk this morning across CT.
      - Main rain during the day across southern New England, transitioning
      to a wintry mix late this afternoon and evening across the higher terrain
      - Minor sleet/snow accumulations of a coating up to 2 inches are
      forecast, as well as ice accretion of a trace up to around 0.10" in spots
      - Greatest travel impacts will be potentially slick roadways and
      perhaps lower visibility across the high terrain, especially at
elevations
      above 1000 feet


   - Sleet, freezing rain, even some locations observing rain change to
   snow this evening into Monday morning
      - Northern and western portions of MA & CT, possibly as far SE as the
      N&W I-495 beltway & I-84 corridor including NW RI
      - Mainly for higher elevations with temperatures at or below
      freezing, will see accumulations of a coating up to around an
inch with the
      greatest travel impact
      - At lower elevations, not expecting much if any snow accumulations
      as roads will remain wet
      - With any snow, anticipate reductions in visibility

*Uncertainty ... *

Given a mixed precipitation event, there remains uncertainty with respect
to precip-types at specific times over particular areas, as well as
associated outcomes and impacts.

As of now the greatest impact appears across the higher elevations of
northern and western portions of MA and CT. However if the storms
intensifies more rapidly than expected wintry precipitation may occur
farther south and east.

There will likely be adjustments to later forecasts so stay tuned to
further emails. Should you have any questions, comments and/or concerns,
please don't hesitate to reach out to us at any time.

Respectfully,

Benjamin Sipprell & Matthew Belk
