Forecasts of snow, sleet and freezing rain threatened to complicate Holiday Day travel around the nation’s midsection Tuesday as several Gulf Coast states braced for a chance of twisters and powerful thunderstorms.

A blizzard watch was posted for parts of Indiana and western Kentucky for storms expected to develop Tuesday amid predictions of up to 4 to 7 inches of snow in coming hours. Much of Oklahoma and Arkansas braced under a winter storm warning of an early mix of rain and sleet later turning to snow.

Some mountainous areas of Arkansas’ Ozark Mountains could get up to 10 inches of snow amid warnings travel could become “very hazardous or impossible” in the northern tier of the state from near whiteout conditions, the National Weather Service said.

Early Tuesday, the Oklahoma Department of Public Safety said some bridges and overpasses were already becoming slick. Also, Kathleen O’Shea with Oklahoma Gas and Electric said the utility was tracking the storm system to see where repair crews might be needed among nearly 800,000 customers in Oklahoma and western Arkansas.

Elsewhere, areas of east Texas and Louisiana braced for possible thunderstorms as forecasters eyed a swath of the Gulf Coast from east Texas to the Florida Panhandle for the threat of any tornadoes.

Storms expected during the day Tuesday along the Gulf Coast could bring strong tornadoes or winds of more than 75 mph, heavy rain, quarter-sized hail and dangerous lightning in Louisiana and Mississippi, the weather service said.
