...As one winter storm ends for the Midwest/Great Lakes, another
potential storm will follow quickly for New England and the
Mid-Atlantic...

...Chilly temperatures continue across much of the eastern and
central U.S. in a winter-like pattern...

A deep longwave trough over the West will funnel in moisture over
parts of the Pacific Northwest, Great Basin and the Rockies, with
possible localized heavy snow over higher terrain, while lower
elevations may experience some light snow showers through the
remainder of today. Heading into Monday, the trough continues to
advance eastward, the system will become more widespread with
chances of precipiation over the Central Plains into the
Mississippi Valley. Precipitation will range between showers and
thunderstorms over Texas and parts of the Southeast, as the system
merges with moisture from the Gulf. Weather Prediction Center has
highlighted a Marginal Risk (level 1/4) for Excessive Rainfall for
parts of the Gulf Coast and Deep South. Meanwhile further north,
expect a wintry mix and snow over the lower parts of the
Midwest/Great Lakes, Central Plains, Mississippi Valley, and Ohio
Valley where the moisture will intertwine with colder air mass by
Monday evening. Over the Upper Midwest/Great Lakes, lake-effect
may increase chances of heavier snowfall. Therefore, several
regions continue to issue Winter Weather Advisories, especially
over the Upper Midwest and Upper Great Lakes.

The frontal system that brought much of the heavy snow over the
northern portions of CONUS, will gradually move into southeastern
Canada today, tapering off the heavy snow with some possible
lingering snow over areas over the Great Lakes that experience
lake-effect. As the surface low deepens and the frontal system
moves northeastward, expect possible widespread
showers/thunderstorms along parts of the Mid-Atlantic and East
Coast Monday through Tuesday. The deepening low, will gradually
move towards New England, aiding in wintry precipiation Monday
into Tuesday, especially for higher elevations. Chances for snow
will be higher over parts of the Appalachians, the interior parts
of New England, and northern Mid-Atlantic. South of the heavy
snow, over the Central and Southern Appalachians, there are
chances for light to moderate freezing rain and icing over the
higher terrain.

As the upper-wave moves eastward and the surface cold front moves
through the region, temperatures over the Northern Plains, Upper
Midwest and Interior Northeast will see below normal temperatures,
with a 12-25 degree difference. Some areas over north-central U.S.
can see high temperatures within the teens 20s. The latest cold
front has brought the coldest air of the season so far to the
central/southern Plains east to the Mid-South, with highs Monday
mainly in the 20s to 40s. To the east, highs will be in the 30s
and 40s for New England and the Mid-Atlantic with 40s and 50s into
the Southeast. The only areas to see some reprieve from the cold
will be along the Gulf Coast and southeast Atlantic Coast as
temperatures climb into the 60s and 70s on the south side of the
lingering frontal boundary.  Conditions will be around or a bit
above average in the West, with 40s for the interior, 50s and 60s
along the West Coast, and 60s and 70s into the Desert Southwest.
Heading into Tuesday, the central Plains begin to see near normal
temperatures.
