The winter weather system, now in its third day, has swept from Minnesota deep into Texas. Wrecks on slippery roads have been reported in Texas, Arkansas and other states across the region all week. The weather service said Wednesday that "the epic ice storm should come to a close on Thursday," and states across the Southern Plains to the Mid-South remain under various storm warnings and advisories. Over 12 million are still under ice storm warnings and 7 million are under winter storm warnings, the weather service said Wednesday.
