[Weather] [2019.02.20 AM Briefing] Wintry Mix Wednesday night into early Thursday morning

[BOX Operations - NOAA Service Account]

Good morning everyone,

A wintry mix event is expected to bring snow and sleet changing to freezing
rain in the interior and rain along the coast Wednesday night into early
Thursday. Details below.

*What has changed:*
- The WINTER WEATHER ADVISORY has been expanded to all of southern New
England except for the Cape and Islands from 7 PM Wednesday through 7 AM
Thursday.

*WHAT: *
- Minor snow and sleet accumulations followed by a period of freezing rain.

*WHERE: *
-  All of southern New England. While most of the freezing rain will be
confined to the interior, even the immediate coast could experience a brief
period of freezing rain Wednesday night.

*WHEN:*
- Snow is expected to arrive in the Hartford/Springfield areas by 6 pm and
will likely impact the latter half of the evening commute.
- In the Boston to Providence corridor snow will begin after the evening
commute.
- Snow changes to sleet then freezing rain from SW to NE between 10 pm and
3 am, then to rain along the coast.
- Precipitation ends Thursday morning, but patchy freezing rain/drizzle may
linger in the interior and impact the morning commute. Temperatures near
and below freezing Thursday morning will result in slippery travel, mainly
north and west of the Providence to Boston corridor.

*POTENTIAL IMPACTS:*
*- *The main concern is for icy untreated roads and walkways Wednesday
night into the Thursday morning commute.
- Ice accretion amounts should be no more than one tenth of an inch so the
risk for tree damage and power outages is low.

*UNCERTAINTY:*
- Exact timing of the snow arrival may still shift by a few hours either
way, so there remains a low chance that it could impact the latter half of
the Boston-Providence commute.
- It remains possible that freezing temperatures could linger during the
morning commute for the Boston metro area, but it is much more likely
northwest of Boston.

Please let us know if you have an questions or concerns.

Thank You

Bryce Williams
