...Coastal rain and higher elevation snow for the Pacific Northwest...

...Snow of the Upper Great Lakes starting Wednesday evening into
Thanksgiving...

...Critical Risk of fire weather over parts of the Central/Southern High
Plains...

A front extending from the Northern Plains roughly southwestward to
Southern California will move eastward to the Lower Great Lakes and
southward to the Central/Western Gulf Coast by Thanksgiving. Energy
associated with the system will produce light snow over parts of the
Northern Intermountain Region/Northern Rockies Tuesday evening into
Wednesday morning.  Early on Wednesday morning, light snow will develop
over parts of the Central Rockies and parts of the Southern Rockies.
Concurrently, rain showers develop over parts of the Southwest and lower
elevations of the Southern Rockies, ending by overnight Wednesday. 
Additionally, a reinforcing front will move southward across the U.
S./Canadian border overnight Tuesday, producing light snow over parts of
the Northern Plains that will taper off by Wednesday evening.  The snow
will result in reduced visibility and hazardous driving conditions.  By
Wednesday evening, the front will dissipate while reinforcing the lead
front over the Upper Great Lakes. Furthermore, light snow will develop
over the Upper Great Lakes on Wednesday evening and expand over Michigan's
Lower Peninsula on Thanksgiving; snowfall amounts will be higher near the
Lakes.

Moreover, moisture from the Western Gulf of Mexico will start to stream
northward ahead of the lead front overnight Tuesday into Wednesday. As a
result, rain will develop along the front late Wednesday night from parts
of Michigan's Lower Peninsula to Arkansas.  Rain and thunderstorms will
also develop along and ahead of the front over parts of the Southern
Plains/Lower Mississippi Valley on early Thanksgiving morning into the
evening.

Meanwhile, over the Central and Southern High Plains, warm temperatures,
dry fuels, and gusty wind will aid in creating a Critical Risk of fire
weather over the region through Wednesday morning.
