A winter storm watch remains in effect for all of north Louisiana through Wednesday afternoon.
The National Weather Service in Shreveport said a mixture of sleet and snow will move into the area Tuesday night.
On Wednesday, much of the precipitation will change over to mostly snow.
Along the Interstate 20 corridor, forecasters said snow accumulations of 1 to 2 inches are possible before the precipitation moves east out of the area.
The winter storm watch stretches west to Tyler, Texas, east to Monroe and north past Texarkana, Arkansas, until 6 p.m. Wednesday. A winter weather advisory for rain, sleet and snow affects the region including DeSoto Parish, Natchitoches, Many and Jena, stretching west to Lufkin, Texas.
Driving in north Louisiana remained hazardous Tuesday.
Louisiana State Police Sgt. Barry Spinny in Bossier City said ice remained on the bridges, overpasses and some highways.
Spinny said the ice was expected to melt Tuesday as the temperature moves above freezing, but it could reform Tuesday night into Wednesday morning as the snow moves over the area.
Public school systems across north Louisiana, as well as Louisiana Tech and the University of Louisiana at Monroe, were closed Tuesday.
