Vermont...
WINTER STORM WARNING IN EFFECT FOR TONIGHT THROUGH FRIDAY MORNING...
Bottom line up front: 8-12" of snow is expected over a prolonged
period, with the bulk of the event occurring Thursday evening and
overnight into Friday morning.
No major changes seen in the 00Z NWP guidance with the NAM and ECMWF
in line with the cooler GFS solutions highlighted for several days.
In general, a slow moving cold front will be the focus for
precipitation across the region as several waves of low pressure
track along the boundary. While there remains the possibility of
some sleet and/or freezing rain in far southern Rutland/Windsor
counties, the probability is rather low and thus we`re mainly
looking at an all snow event with some rain initially in the lower
Connecticut River Valley. Light snow will develop across the St.
Lawrence Valley this evening and spread eastward into western
Vermont by sunrise with 1-2" of accumulation west of the Champlain
Valley and just a dusting east. Snow then continues through the day
across the region but remains relatively light with additional
accumulations in the 1-3" range through sunset. The bulk of the
event comes Thursday night where shortwave energy ejecting out of
the southeast will enhance snowfall across the region, especially
over central/southern portions of the area with 1-2"/hr snowfall
rates are likely. While initial snow ratios will range from 8-10:1
during the daylight hours, strong cold air advection behind the
front will bring ratios up to 12-15:1 overnight as surface to
mountain top temperatures fall into the single digits and teens.
Additional accumulations by sunrise Friday will range from 3-6"
across northern New York and 4-8" across Vermont. Snow then tapers
off Friday morning across northern New York but lingers into the
afternoon across Vermont where an additional 1-2" is likely.
With the prolonged nature of the event and the bulk of snow coming
through the overnight the main impact from the storm will be travel
related with snow covered roads expected. A lack of any strong low
level jet during the main portion of the event, and average snow
ratios generally expected, we don`t foresee any widespread power
outages.
