...CRITICAL FIRE WEATHER AREA FOR NORTHERN ARIZONA AND SOUTHERN
UTAH...

DRY SOUTHWESTERLY TO WESTERLY FLOW UNDER A BUILDING RIDGE ALOFT WILL
BRING A BROAD FIRE WEATHER CONCERN TO PORTIONS OF THE SOUTHWEST,

SUPPORTS THIS BROAD FIRE WEATHER THREAT. ELEVATED HIGHLIGHTS HAVE
BEEN EXPANDED NORTHWARD INTO EAST-CENTRAL NV AS WELL AS THE CO
WESTERN SLOPE AND EASTERN UT BASED ON LATEST FORECAST GUIDANCE AND
INCREASINGLY RECEPTIVE FUELS.
..NORTHERN ARIZONA AND SOUTHERN UTAH

SHIFTED SLIGHTLY EASTWARD BASED ON LATEST MODEL GUIDANCE, WITH LOWER
PROBABILITIES OF REACHING CRITICAL FIRE WEATHER CRITERIA ACROSS THE
AZ STRIP.
