[Weather] [2019.12.26 PM] NWS Boston EM Briefing: Light Wintry Mix Overnight into early Friday

[BOX Operations - NOAA Service Account]

Good afternoon,

We still expect the threat of spotty light freezing rain and/or sleet
across portions of western and northern MA after midnight through the
Friday morning commute. Winter Weather Advisories may be issued with later
forecasts if confidence grows in the threat of more widespread freezing
rain. A Special Weather Statement has been issued to highlight the greatest
concerns.

Attached is the latest thinking on precipitation types, as well as ice
accretion.

*Locations:* The higher terrain towards the Berkshires, as well as northern
MA generally along and north of Route 2.

*When:* Between midnight and 9 AM Friday

*What:* Light ice accumulations up to a few hundredths of an inch.
Negligible sleet accumulations.

*Impacts:* Untreated surfaces may become slippery and lead to travel
difficulties for the Friday morning commute.

*Confidence:*  Moderate to high on precipitation types, closer to moderate
on expected ice accumulations. Though the area threatened by freezing rain
is fairly broad, freezing rain in any area may prove quite light and spotty
in nature. This is likely to significantly limit ice amounts and coverage.

Please let us know if you require additional information.

Matthew Belk
