LITTLE ROCK, Ark. (AP) - Forecasters say severe thunderstorms and a few tornadoes are possible Tuesday in areas along the Mississippi River Valley.

The Storm Prediction Center in Norman, Oklahoma, says northeast Arkansas, southeast Missouri and extreme western Tennessee are at the greatest risk of severe storms Tuesday.

Forecasters say multiple rounds of thunderstorms are expected in the area ahead of a cold front moving east. Damaging winds are expected to be the biggest concern, but forecasters say tornadoes are possible, too.

The Storm Prediction Center says Tuesday’s stormy weather could affect about 30 million people in an area stretching from Louisiana to Illinois.

Meanwhile, parts of the western U.S. were being pummeled by a snowstorm ahead of the busy Thanksgiving travel period.
