...Winter weather possible for the return from the Thanksgiving holiday
from portions of the Southern to  Central Plains into the Mid to Upper
Mississippi Valley and Western Lakes region..

...Rain possible along the Gulf Coast and the Northern Mid-Atlantic to New
England coasts...

...Below average temperatures to spread eastward from the Plains into the
Mississippi and Ohio Valley region for the start of the work week...

...Tranquil weather on tap from the High Plains, west to the West Coast...

The last part of the return trip from the Thanksgiving holiday will bring
the potential for accumulating snows and travel disruptions from portions
of the Central to Southern Plains, northeastward into the Mid to Upper
Mississippi Valley and western Great Lakes.  This is in response to an
upper level low, that has already produced widespread heavy snows across
the Northern to Central Rockies, pushing northeastward from the Central
Plains into the Great Lakes and a more northern area of low pressure
moving along the south central Canada/north central U.S. border area into
the Great Lakes.  Snowfall amounts are expected to be lighter than what
fell through the Northern and Central Rockies, with accumulations
generally in the 2 to 4 inch range.  Travel disruptions also possible
along the immediate Gulf Coast from Texas to Florida as rainfall is
expected to develop across this region on Sunday.  Stormy weather also
possible late Sunday into early Monday from the Northern Mid Atlantic
coast, northeastward along the New England coast as an area of low
pressure deepens across this area.  This may produce some moderate to
locally heavy precipitation totals, but temperatures are expected to be
warm enough to keep the precipitation as rain.

In the wake of the system pushing northeastward from the Plains into the
Great Lakes, below average temperatures will be spreading eastward Sunday
into Monday from the Plains into the Mississippi and Ohio Valley regions. 
This cold air will then push into the eastern U.S. by Tuesday.  As the
cold air pushes across the Great Lakes late Sunday into Monday, lake
effect snow showers will develop from west to east in the lee of the Great
Lakes.  This will support locally heavy snowfall amounts across the
favored lake effect snow regions of the Upper Peninsula of Michigan, the
western portions of the Lower Peninsula of Michigan and from far northeast
Ohio, far northwest Pennsylvania into far western New York State and
northern New York State.

Meanwhile, mostly tranquil weather expected from the High Plains, westward
through the Rockies and to the West coast as high pressure will remain
centered across the Central Rockies and provide for dry weather.  The
clear skies and dry weather will bring the potential for freezing
temperatures over the next few mornings through the interior Valleys of
California where freeze warnings are in effect for Sunday morning.
