A storm system in the U.S. West is expected to pose a triple threat to the country over the next three days, eventually bringing snow to the Southwest, a blizzard to the Central Plains, and severe storms to Texas, Louisiana, and Arkansas, according to CNN's weather unit.
Portions of California, Nevada, Arizona, New Mexico and Colorado, especially those at higher elevations, face winter storm conditions over the next 24 hours.
Then, the National Weather Service says portions of Kansas and Nebraska could see more than a foot of snow by Thursday. Meanwhile, significant ice buildup could make travel treacherous in the southern Plains. The weather service advises postponing travel until after the storm passes if possible.
Additionally, areas farther south including Texas, Louisiana, Arkansas and Mississippi, could see severe thunderstorms with possibly strong tornadoes from this weather system, CNN's weather unit says.
Later on in the week, the storm system could dump up to six inches of rain on areas from Mississippi to Georgia.
