Millions of people are under winter storm advisories as snowstorms and heavy rain sweep across the US

Parts of Wyoming and Nebraska are under blizzard warnings, while winter storm warnings and advisories are in effect for other parts of the region, CNN meteorologist Tyler Mauldin said.

The system will bring heavy rainfall about four inches across the Midwest for a 72-hour period before slowly migrating to the East Coast next week, bringing wet days.

And once it diminishes in the regions hit by snow on Monday, another system is poised to take its place and continue to provide winter weather, Mauldin said.

Snowstorm conditions

Snow through central parts of the US is expected to increase Saturday, but probably won’t peak until Sunday, Mauldin said.

Denver could see up to 2 feet of snow, with the Front Range Mountains and Foothills possible up to four feet. The highest elevations in southeastern Wyoming could see over four feet of snow.

This area is no stranger to the snowfall in March. In fact, March is actually the snowiest month of the year for parts of Colorado and Wyoming. In Denver, each of the top March 10 snowstorms totaled over 12 inches of snow. This year could be added to that list.

“The snow totals currently forecast are absolutely historical,” said the NWS office in Cheyenne said

On Sunday, severe storms will move east to Arkansas, Mississippi, Louisiana and Tennessee.

Floods are a threat throughout the Midwest

Rain threatens flooding

Flood warnings are also a major concern for this Midwestern system.

With some rivers approaching the inundation phase, the expected heavy rain could bring the rivers to dangerous levels.

Floods are also a threat on Sundays, especially in parts of Missouri, Kansas and Illinois.

Other states – such as Arkansas, Oklahoma, Kentucky and Indiana – could also see flooding, especially if multiple storms pass over the same locations, according to forecasts.

Widespread rainfall totals through Sunday are expected to be in the 2 to 4 inch range, but some isolated spots can exceed 6 inches.
