After bringing blizzard conditions to Kansas, dropping the biggest snow in years across the Midwest, and raining crippling ice across Missouri and the Ohio Valley, the ongoing winter storm is now bringing its fury to the mid-Atlantic states.

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.

A powerful storm front spawned multiple tornadoes in the Greater Houston metro area Saturday afternoon, officials said.

Southeastern states are on alert as severe weather moves through the area tonight. Several tornado watches and warnings have went into effect across Texas, Louisiana and Mississippi.

After severe storms erupted across the lower Mississippi Valley on Sunday, the threat for strong storms will shift to the Deep South and Florida peninsula on Monday.
