Crews in Arizona managed to gain ground on Saturday night against a wildfire burning in the southern part of the state, as critical fire conditions remain throughout the region.
Gusty winds, low humidity levels, and dry lightning will keep wildfire conditions elevated from the Southwest to the Southern Plains for the first half of the week.
Red flag warnings and fire weather watches are in effect for the region.

The National Weather Service’s (NWS) Weather Prediction Center (WPC) said critical fire weather is possible in portions of the Four Corners states an well as the southern and central Plains.

In Arizona, the Bighorn Fire burning north of Tucson is now 11 percent contained after burning some 11,500 acres in a national forest. The blaze was started by lightning on June 5 and had led to the evacuation of several hundred residents last Thursday.
Many were allowed to return home by Friday, but told to remain ready to leave at a moment’s notice.
Flames have been visible from Tucson at night, and smoke from the fire plumed over a suburb Friday morning. Later in the day, an air tanker was seen spreading red fire retardant over the flames.
Authorities have said southern Arizona’s dry, hot weather and the steep, rocky topography have been the main challenges in fighting the fire. Friday was the hottest day yet for crews battling the blaze, with temperatures reaching 107 degrees in the afternoon.
In other parts of the state, fire crews have been busy over the weekend.
