States from California to Colorado and Wyoming are dealing with heavy snowfall, as a fierce winter storm moves across much of the western U.S.
Meteorologists forecast 10-15 feet of snow to bury California and wintry weather also to target South. Southern snow?
A series of winter storms is forecast to continue hammering California with several feet of heavy snow and driving rain over the next few days and into the weekend.
Meanwhile, a storm could also spread a stripe of snow across the South, all the way from Texas to Virginia, from late Thursday into Saturday.
In the West, the combination of storms through this weekend has the potential to bring the biggest amount of rain and mountain snow to California since the drought began several years ago.
Several feet of snow have already fallen in the Sierra Nevada from one storm, and several more feet is on the way from a second, more intense storm that should hit over the weekend.
One ski area, Squaw Valley, has recorded 7 feet, according to its Twitter account.
Another 10 to 15 feet of snow could bury portions of the Sierra over the next 10 days.
Closer to the coast, heavy rain could lead to flooding, mudslides and debris flows in both the San Francisco and Los Angeles metro areas.

The source of the heavy rain and snow in the West is what meteorologists call an “atmospheric river,” which acts like a fire hose to funnel moisture from the tropical Pacific toward California.
These rivers transport huge amounts of water vapor toward the West, where it’s wrung out in the form of rain and snow, noted Mashable’s Andrew Freedman.

Any snow that falls in the South over the next few days will be measured in inches, not feet, but it doesn’t take much to wreak traffic chaos there. After one round of snow Thursday in the Ohio Valley and Appalachians, more substantial snow could fall by Friday and Saturday in the South.

Cities at greatest risk for some snow, a wintry mix or flash freeze Friday and Saturday include Jackson, Miss.; Birmingham, Ala.; Chattanooga, Tenn.; Atlanta; Charlotte, Winston-Salem and Raleigh, N.C.; and Richmond, Va. The potential exists for difficult winter driving conditions in parts of the South beginning Friday.
There is an anomalous weather pattern currently sweeping across California and the Southern United States.
