[Weather] [2020.01.08 AM] (CORRECTED Date/Time) NWS Boston EM Briefing: Scattered Snow Squalls This Afternoon, Developing Black Ice Tonight

[BOX Operations - NOAA Service Account]

Good morning,

Following e-mail is a correction to one previously sent with a corrected
date/time stamp. Information contained is unchanged from the previously
sent e-mail and remains valid. Apologies for the error!

This e-mail is to raise awareness of scattered snow squalls for this
afternoon into early tonight, with much colder air tonight contributing to
the development of patchy black ice on untreated surfaces tonight.

Details on each below:

*Scattered Snow Squalls*

*Where: *Possible anywhere in Southern New England, though greatest
potential is into interior MA (near and west of I-495), northern RI and
northern CT.

*When:* Between noon and 6 PM today.

*Impacts:* While not everyone will see snow squalls, areas that do will see
short-lived heavy snow capable of brief whiteout conditions and gusty
winds. A quick coating-inch of snow accumulation is possible in less than
an hour's time in snow squalls. These conditions may make for difficult
travel which could impact this afternoon's commute.

*Uncertainty:* Coverage of snow squalls will be localized, with several
areas staying dry. There is less certainty on snow squalls advancing into
the coastal plain with temperatures hovering near or just above freezing.

Following attachment is a Special Weather Statement sent this morning about
our expectations for snow squalls this afternoon into tonight.

*Black Ice/Freeze-Up*

*Where: *Possible anywhere in Southern New England where snow and/or wet
pavement exists.

*When:* Developing tonight into the overnight. Threat should end after
sunrise Thursday.

*Impacts:* Wet or slushy pavement will turn slippery if untreated. Shaded
locations, side streets, bridges and overpasses are most vulnerable.

*Uncertainty*: Generally low with high confidence on sub-freezing
temperatures. Gusty winds and drier air tonight may evaporate damp pavement
in spots before freezing.

Attached is a look at tonight's low temperatures based on our
overnight/early morning forecast. While we are still fine-tuning these low
temperatures,  any change will likely be minimal.


Please let us know if you have any questions or concerns!

Thank You!
