An arctic airmass moved into the region during the week of January 31-February 4, 2011. High temperatures on February 1 and February 2 struggled to get above freezing across most of the region, and each night the temperatures dropped into the teens in most locations.

A large upper level system moved across Texas, tapping into moisture from the Gulf of Mexico and the Eastern Pacific Ocean, and streaming it up and over the cold air in place. As a result, the area received the full gammit of winter weather from significant ice accumulations to heavy snows. Significant ice was reported across the southeastern parishes in Louisiana with a mixed bag across the central portion. Heavy snow fell across northwest portions of the area with amounts ranging from 3 inches to as much as 8 inches in a few locations along the Interstate 30 corridor.

Some impacts from the winter weather included:
  • All schools were closed across the entire 48 county/parish area.
  • Power outages were reported across Natchitoches, Grant, Winn, Caldwell, LaSalle, Jackson, and Ouachita Parishes due to ice on trees and power lines.
  • Numerous auto accidents occurred across the Four State Region. Several highways and overpasses were closed due to icing including the I-220 and I-49 overpasses in Shreveport, the I-30 interchange in Texarkana, and I-20 ramps in Monroe.
