WASHINGTON: It was too cold for school in Chicago and other Midwestern cities Friday as a huge, dayslong winter storm began to crank up that could bring snow, sleet, ice and bone-chilling temperatures as well as extensive power outages to about half the US population from Texas to New England. Forecasters warned that the damage, especially in areas pounded by ice, could rival a hurricane. Airlines canceled thousands of flights, churches moved Sunday services online and the Grand Ole Opry in Nashville, Tennessee, decided to hold its Saturday night radio performance without fans.

A high-impact winter storm will spread snow and ice across more than two dozen states from Friday through the weekend.

Snow and ice will impact dozens of states from Texas through the Northeast this week, forecasters warned.
