[Weather] NWS Boston EM Briefing: Wintry Mix Thursday Morning Commute Potential

[BOX Operations - NOAA Service Account]

Good afternoon everyone,

We just wanted to give  a heads up on the likelihood for a wintry mix to
impact portions of our region during the Thursday morning commute.  While
specifics need to be ironed out, below is an outline with our current
expectations.

*What: *
- Sleet and Freezing rain along with the potential for a period of snow at
the onset.

*Where: *
- The potential exists for a brief period of snow/ice across the entire
region. However, the concern for a prolonged period of wintry precipitation
will be northwest of the Boston to Providence corridor especially across
interior Massachusetts and northern Connecticut.

*When: *
- Precipitation starts between 1 and 7 AM  Thursday morning.  A wintry mix
will change to rain by late Thursday morning across eastern MA/RI, but
icing may continue into Thursday afternoon across portions of interior MA
and northern CT.

*Potential Snow/Ice Accumulations: *
- Snow accumulations of a dusting to 3 inches with the greatest risk for
snow in northern MA.  Ice accretion of a few hundredths up to one quarter
of an inch possible.

*Uncertainty/Impacts: *
- Confidence is high that precipitation begins as a wintry mix to the
northwest of the Boston to Providence corridor with an impact to the
Thursday morning commute.
- Along and southeast of the Boston to Providence corridor, the potential
exists for a brief wintry mix at the onset but will likely be short-lived
with a change to rain.
- Confidence is lower as to whether or not there is any snow at the onset
or if precipitation begins as just sleet and freezing rain. Greatest risk
for a few inches of snow will be across northern MA.
- Icing may persist into Thursday afternoon across portions of interior MA
& northern CT, but most locations should change to rain by early Thursday
evening.
- The potential of exceeding one quarter of an inch of ice accretion is
rather low at this time.

Thank You
