The next round of bitter cold is set to envelop the southern U.S., after the first significant winter storm of the year blasted a huge swath of the country with ice, snow and wind. The immense storm system brought disruption even to areas of the country that usually escape winter’s wrath, downing trees in some Southern states and threatening a freeze in Florida. The National Weather Service said the wind chill temperature was 16 at Dallas/Fort Worth International Airport early Tuesday. A low-pressure system is then expected to form as soon as the next day, bringing snow to parts of Texas, Oklahoma and Arkansas.
