...Snow Squalls and Strong Wind Gusts This Afternoon...

A strong cold front will bring scattered snow showers and a few
heavier snow squalls this afternoon. Highest confidence in
squalls is in the interior north and west of I-95 where localized
brief squalls could produce a quick inch or 2 of snow and very
poor visibility leading to hazardous travel conditions.
Temperatures are expected to drop quickly behind the front and
will result in untreated wet surfaces to freeze. Timing of the
squalls will be 1 to 3 pm in western MA and northern CT and 3 to 6
pm in eastern MA and Rhode Island.

Areas along and south and east of I-95, any showers should start
as rain before changing to snow, but less impact is anticipated
here due to above freezing temperatures and roads remaining mostly
wet.

In addition, brief wind gusts to 40 to 50 mph are possible this
afternoon along and just behind the front as winds shift from
southwest to west.
