On April 5, 2022, eleven counties in northern and western Arkansas (Ozark and Ouachita Mountains) were split into twenty five zones based on climatological differences (mainly due to terrain) and to help forecast elevation dependent weather events more accurately. The split affected Boone, Johnson, Logan, Montgomery, Newton, Polk, Pope, Scott, Searcy, Van Buren, and Yell Counties. Roughly four years later, three counties were divided in west central sections of the state (Arkansas River Valley). This included Crawford, Franklin, and Sebastian Counties.
