...New England...
Day 3...

A northern stream low currently over the Dakotas will slowly swing
across the northeastern CONUS Monday night through Tuesday night.
The surface focus will shift from the eastern Great Lakes to a
newly developing coastal low south of Long Island on Monday. This
will focus the cold conveyor belt into northern New England
through Monday night and allow mountain snows focus mainly in this
time. This happens to be nocturnal which will help snow
accumulation. Snow elevation per the NBM is between 2000 and
3000ft which should limit heavy snow to above about 4000ft. As
such the Day 3 probabilities for eight inches are limited to the
White Mountains of NH/western ME.


The probability of significant icing is less than 10 percent.
