If you noticed a hazy appearance to the sky across the Texas and Oklahoma Panhandles on Tuesday, it was no illusion. It was actually the result of a large wildfire burning in eastern Arizona, named the Wallow Fire. As seen on the visible satellite image below from early this afternoon, a plume of smoke originating from the fire extended from West Texas through Nebraska. Southwesterly winds at mid to upper levels of the atmosphere were responsible for transporting this layer of smoke at high altitudes into the Southern and Central Plains. Also visible is a thick smoke plume across eastern Arizona and western New Mexico near the fire.
