A severe winter storm began moving into Arkansas late Friday, bringing sleet, snow, freezing rain and brutally cold temperatures.

Here's how we expect the weekend snowstorm to develop:

More than 160 million people are on alert for a brutal storm. More than 160 million people are on alert for a brutal weekend storm that's going to bring dangerous ice and snow to the South, bitter cold to the Midwest, and snowfall to the Northeast.

Rain, snow, and very cold temperatures will be moving into Arkansas this weekend. Saturday and Sunday are severe days.

An arctic cold front is expected to dump 4 to 8 inches of snow on most of Arkansas this weekend, with accumulations of as much as 12 inches possible in the Ozark and Ouachita mountains.

40/29 Chief Meteorologist Darby Bybee says much of the area is expecting to see its heaviest snowfall in 15 years.
