As a coast-to-coast winter storm slices across the U.S. Sunday and Monday, severe thunderstorms are expected to fire up across portions of the South on the warm side of the storm system.

Severe storms batter the South with tornadoes, damaging winds and hail as large portions of Texas, Mississippi and Louisiana are under weather alerts.

A line of severe thunderstorms is expected to push through the South on Sunday afternoon and evening with the threat for damaging winds and a few tornadoes. Time the squall line here.
