AccuWeather meteorologists say a storm in the central Rockies will move into the southern and central Plains, developing a new area of low pressure on Friday. At the same time, cold air from the Rockies and northern Plains will collide, and humid air from the Gulf of Mexico will spark powerful thunderstorms. 

Folks in eastern Texas into Arkansas, Louisiana, Mississippi, and western Tennessee should be on watch for dangerous thunderstorms on Saturday. 

Focusing on what readers are most interested in: There's a significant possibility of heavy snowfall across the Midwest to the interior Northeast. 

"This storm will interact with cold air on the northwest side of the storm," AccuWeather Meteorologist Joe Bauer said.
