[Weather] [Feb 17 430PM] NWS Boston Emergency Management Weather Briefing - Brief Period of Wintry Mix High Terrain of Massachusetts

[BOX Operations - NOAA Service Account]

All,

*Not* a major or widespread winter weather event Tuesday but some impacts
in the form of slippery travel across the Worcester Hills and east slopes
of the Berkshires from late morning into the afternoon, especially the
highest elevations in these areas.  Additional details below.

*What ... *A brief period of snow or sleet to light freezing rain before
changing over to all rain

*Where ...* the Worcester Hills and the east slopes of the Berkshires
especially the highest elevations of these areas

*When ...* Late Tuesday morning into the afternoon

*Impacts ...* a 3 to 6 hour period of snow or sleet to light freezing rain
will result in slippery travel especially on untreated surfaces. By 4 or 5
pm, all areas should have changed over to plain rain with temperatures
above freezing.  So other than possibly a very brief period of snow and/or
sleet at the start, rain will be the predominant precipitation type for the
cities and suburbs of Boston, Providence and Hartford. Temperatures will be
above freezing across these areas so roadways will just be wet.

*Forecast Confidence ...* high confidence in a short duration wintry event
(3-6 hours) with minor snow accumulations (a coating to 2 inches) and very
minor ice accretions (less than 0.05 inches) across western and central
Massachusetts. This includes the Worcester Hills and the east slopes of the
Berkshires. There is still some uncertainty that impacts could be felt as
far south into northwest Hartford county. However, confidence is low at
this time.

*Attached Graphics ...*

   - A loop beginning at Tuesday 8 am and ending at 7 pm showing an
   approximate timeline and precipitation types of snow (blue), a wintry mix
   (purple) and freezing rain (red) moving across the region tomorrow/Tuesday


   - Expected snow totals.  Only a coating to 2 inches across western and
   northwest MA.  Little, if any snow accumulation elsewhere.


   - Expected ice accretion.  A trace to 0.05 inches with greatest risk
   across the highest elevations. Little, if any ice accretion elsewhere.
