From AccuWeather.com: The National Weather Service in Shreveport has issued an ice storm warning, which is in effect from 6PM Thursday to 6PM Friday.
Freezing rain will begin accumulating overnight Thursday through the day Friday with ice accumulation near or in excess of one half inch northwest of the Interstate 30 corridor of NE Texas, SE Oklahoma and SW Arkansas. Along and south of the interstate 30 corridor, ice accumulation near one quarter of an inch will be possible.
Due to ground warmth, ice accumulation will likely be on elevated objects such as bridges, overpasses, trees, and electrical lines. However., if the temperature can stay below freezing long enough into Saturday, a few secondary roadways may become hazardous as well.
An ice storm warning means severe winter weather conditions are expected to occur. Significant amounts of ice accumulations will make travel dangerous or impossible. Travel is strongly discouraged. If you must travel, keep an extra flashlight, food and water in your vehicle in case of an emergency. Ice accumulations and winds will likely lead to snapped power lines and falling tree branches that add to the danger.
