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

...Southern Great Basin, Colorado Plateau and Four Corners...
Dry southwesterly to westerly flow under a building ridge aloft will
bring a broad fire weather concern to portions of the Southwest,
southern Great Basin and CO Plateau Tuesday. Poor overnight
recoveries through tonight will precede daytime minimum RH of 5-15%
across this region. The very low daytime RH, sustained
west-southwest winds of around 15 mph and critically dry fuels still
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...
A corridor of enhanced westerly winds up to 20 mph amid RH as low as
10% will yield a period of critical fire weather conditions for
parts of northern AZ into southern UT. The highlighted area was
shifted slightly eastward based on latest model guidance, with lower
probabilities of reaching critical fire weather criteria across the
AZ Strip.

...Synopsis...
Upper ridging will persist over the Interior West while building
into the Northern Plains tomorrow (Tuesday). An embedded mid-level
impulse will overspread the central Rockies, supporting surface lee
troughing intensification over Intermountain West. Dry and breezy
conditions will result Tuesday afternoon over the southern Great
Basin into the Four corners, where Elevated highlights have been
introduced. Critical highlights have also been introduced where
guidance consensus depicts 20+ mph sustained westerly surface winds
coinciding with 10-15 percent RH atop fuels receptive to fire
spread.
