A blast of cold arctic air on its way to south Louisiana is prompting officials to post a winter weather advisory, in effect starting Thursday night.
The cold air will move in early Thursday morning, dropping temperatures into the 40s. After that, a disturbance moving in from the west could lead to freezing rain for parts of the area.
The local National Weather Service office says accumulations of less than a tenth of an inch are expected.
The biggest concern will be for icing on elevated roads and bridges, along with isolated power outages from icing on trees and power lines.
Sunny but cold conditions will be in place over the weekend.
