.WHAT HAS CHANGED...
The Blizzard Warnings have been cancelled and an SPS has been
issued.

&&

.KEY MESSAGES...
1) Impactful winter storm continues to exit the area tonight.
Gusty winds and blowing snow remain possible.

2) A passing warm front will bring some light snow and rain on
Wednesday. A stronger low passing close by will bring additional
wintry precip Thursday into Thursday night.

&&

.DISCUSSION...
.KEY MESSAGE 1...

The intense coastal low that has brought 18-30" of snowfall to
much of the area today will continue to track northeast into the
Canadian Maritimes tonight.

Gusts of 30-40 mph will gradually decrease through the
overnight, becoming more occasional and closer to 20-30 mph late
tonight thru Tuesday aft.

These gusty winds will result in areas of blowing snow and locally
reduced visibilities overnight into the Tuesday morning
commute. Additionally, areas of black ice will be likely across
the area tonight, especially on any untreated surfaces, as
temperatures drop below freezing again tonight. An SPS
highlights these potentials.

.KEY MESSAGE 2...

As a clipper low passes to the north on Wednesday, an
associated warm front should bring some light snow and rain on
Wed. Accumulations should be on the light side, ranging from
less than an inch across Long Island, to around an inch in NYC
and along the CT coastline, to 1-2 inches north/west of there.

A stronger low moving from the OH valley to the lower Great Lakes on
Thu could bring more wintry precip. NBM thermal profiles were mainly
supportive of snow and/or rain. Any snow amts should be light,
no more than an inch or two of snow most places and a light
glaze of ice inland NW of NYC. Either way advisories could be
needed for parts of the interior north/west of I-287 in NJ/NY
and along the I-84 corridor in CT.

High temperatures Tuesday range from the upper 20s to lower 30s,
then trend closer to normal the rest of the week. This will allow
for gradual snow melt each day, and with mostly sub-freezing
temperatures at night into early morning, subsequent re-freeze of
snow melt.
