DES MOINES, Iowa—A sprawling storm hit the U.S. South, with tornado warnings and high winds that blew roofs off homes, flipped over campers, and tossed about furniture in Florida on Tuesday, while another storm buried cities across the Midwest in more than a half a foot of snow, stranding people on highways as it headed to the Northeast.
The weather has already affected campaigning for Iowa’s Jan. 15 precinct caucuses, where the snow is expected to be followed by frigid temperatures that could drift below zero degrees (minus 18 Celsius). It forced former President Donald Trump’s campaign to cancel multiple appearances by Arkansas Gov. Sarah Sanders and her father, former Arkansas Gov. Mike Huckabee, who had been scheduled to court Iowa voters on Trump’s behalf Monday.
