...Severe thunderstorms possible across parts of the Southern Plains into
parts of the Lower and Middle Mississippi Valley through Sunday morning...

Valley, Western Tennessee Valley and West Virginia...
...Snow over parts of the Central Rockies and Central High Plains...
Scattered to widespread showers and thunderstorms continue to impact
portions of the Southern and Central Plains, Lower and Middle Mississippi
Valley and western Tennessee Valley. Strong to severe storms are dumping
excessive rainfall as they move through the area. A few locations already
have ongoing flooding, however the risk across the entire region will
remain elevated through the weekend as the frontal system tracks eastward.
Meanwhile, upper-level energy over the Great Lakes will move eastward off
the Northern Mid-Atlantic Coast by Saturday morning, producing rain from
the Great Lakes to the Northern Mid-Atlantic and Southern New England by
early Saturday morning before ending.
On the cold side of the system, primarily Central Rockies and the adjacent
plains, rain and snow is occurring. Numerous winter storm warning and
advisories are in effect for the Rockies in north-central New Mexico and
Colorado, southeast Wyoming and the western half of Nebraska. Snow will
persist over parts of the High Plains into Saturday and through the
weekend across portions of Colorado. Total snow accumulations from this
system will vary greatly at lower elevations - 1 to 6 inches will be
common. Isolated areas in southwest Colorado, southeast Wyoming and the
Nebraska panhandle could range from 8 to 18 inches by Monday evening.
A cold front plunging through California and Great Basin is bringing
additional rain and highest elevation snow over parts of the Northern
Intermountain Region and the Northern Rockies today. As the system
continues to move south through the Southwest and Southern Rockies, rain
with embedded thunderstorms will develop over the Great Basin and Southern
Rockies and expand northward into the Central/Northern Rockies by Saturday
