Tornadoes ripped through four states on Tuesday night and Wednesday, killing at least two people, as an Arctic cold front clashed with warm air to produce severe weather over a wide swath of the nation. Tornadoes were reported in Mississippi, Georgia, Indiana and Tennessee, an unusual development in January when the focus is more likely to be on snow and ice. The National Weather Service said twisters touched down in Sardis, Mississippi, and heavily damaged homes in Solsberry, Indiana, wiping out power in the surrounding areas. Three twisters were confirmed in Tennessee and a possible tornado hit southeastern Arkansas.
