...Periods of light to moderate snow spreading across the Great Lakes and
Northeast...

...Low pressure system continues to bring showers and thunderstorms to the
Gulf Coast tonight; reaches Florida Peninsula on Tuesday...

...Cold air intrusion expands from Northern Plains and Upper Midwest into
the South and East through Wednesday; Warm air expands across
Northern/Central Plains beginning Tuesday night...

The second in a series of fast-moving low pressure waves from Alberta
Canada is tracking across the Great Lakes this afternoon. This Alberta
clipper will bring a quick round of light to moderate snow from the Great
Lakes through New England tonight into Tuesday.  Up to a few inches of
snow can be expected in these areas through tonight, but higher amounts
are possible downwind of the Great Lakes due to lake-effect enhancements. 
Southwesterly winds developing ahead of the clipper will moderate the
arctic air mass that settled across the southern and eastern U.S..

Meanwhile, a closed upper-level low/trough tracking eastward into southern
Texas will induce a low pressure system to form just off the Texas coast
tonight. This system will tap into Gulf moisture and track quickly
eastward, bringing a round of showers and some thunderstorms from west to
east through the Gulf Coast tonight into Tuesday before reaching the
Florida Peninsula. The heaviest rainfall is forecast to stay just off the
coast.

Farther to the north, a shortwave impulse will dive down the spine of the
Rockies tonight into Tuesday.  This bit of energy will trigger snow
showers from the Rockies into western Kansas with heavier snow likely over
the higher elevations. Meanwhile, the Northern and Central Plains will
experience a drastic cool down tonight in the wake of the cold front
associated with the Alberta Clipper. Air temperatures will be in the
negative teens and twenties for much of Minnesota and North Dakota tonight
with wind chills potentially reaching -40 degrees in come places. Wind
Chill Advisories and Warnings are in effect for much of the Northern
Plains and Upper Midwest tonight. This cold airmass will spread into the
Midwest and Northeast by Wednesday with high temperatures not making it
out of the teens over parts of the Interior Northeast. High temperatures
will be much below normal over much of western Texas into eastern New
Mexico as well on Wednesday.
