A developing winter storm threatens to drop snow, sleet and freezing rain on parts of Texas, Oklahoma and Arkansas as frigid air that escaped the Arctic plunges temperatures to subfreezing levels in some of the southernmost points of the U.S.
National Weather Service meteorologists predicted wintry precipitation across the southern Plains region starting Wednesday night, with snow likely in Texas, Oklahoma and Arkansas. Farther south, snow could transition to sleet and freezing rain, which meteorologists warn could result in hazardous driving conditions.
