DRY DOWNSLOPE FLOW EAST OF THE SIERRA CREST ALONG WITH DRY FUELS
WILL CONTRIBUTE TO ELEVATED FIRE WEATHER CONDITIONS ACROSS FAR
WESTERN NEVADA THIS AFTERNOON. SINGLE DIGIT RELATIVE HUMIDITY ALONG
WITH BREEZY SOUTHWEST WINDS ARE EXPECTED ACROSS CENTRAL/SOUTHERN
NEVADA AND SOUTHWESTERN UTAH. HOWEVER, MID AND UPPER SLOPE
FUELSCAPES REMAIN LARGELY IN GREEN UP PHASE, LIMITING FIRE SPREAD
POTENTIAL TO LOWER ELEVATION CURED GRASSES WITH AVERAGE FUEL
LOADING.

..SYNOPSIS
A BELT OF MODEST MID-LEVEL FLOW WILL BE POSITIONED OVER THE GREAT
BASIN DURING THE DAY, AND STRONG MIXING DURING THE AFTERNOON IS
EXPECTED TO BRING SOME OF THAT FLOW TO THE SURFACE, RESULTING IN A
COUPLE AREAS OF FIRE WEATHER CONCERNS. AN ELEVATED AREA WAS
MAINTAINED ACROSS PARTS OF NORTHWESTERN NEVADA, WHERE RH IS EXPECTED
TO BE NEAR 5-15% WITH 15-20 MPH SURFACE WINDS ATOP DRY FUELS.
SIMILAR ATMOSPHERIC CONDITIONS ARE EXPECTED ACROSS EASTERN NEVADA
INTO WEST-CENTRAL UTAH, HOWEVER FUELS IN THIS REGION ARE NOT AS DRY.
THEREFORE, HAVE HELD OFF ON INTRODUCING ELEVATED HIGHLIGHTS IN THIS
AREA FOR NOW.
