LATEST MODEL CONSENSUS CONTINUES TO INDICATE A BROAD FIRE WEATHER
THREAT ACROSS PORTIONS OF THE SOUTHWEST TODAY. EXPECTED
METEOROLOGICAL CONDITIONS SUPPORTS EXPANSION OF CRITICAL HIGHLIGHTS
WELL INTO PORTIONS OF NORTHEAST ARIZONA. HOWEVER, FUELS ARE
UNDERGOING GREEN-UP TRANSITION ACROSS THE FOUR CORNERS AREA WHICH
SHOULD ACT TO MITIGATE SIGNIFICANT WILDFIRE SPREAD, ALTHOUGH
ELEVATED HIGHLIGHTS WERE EXPANDED NORTHWARD INTO SOUTHEASTERN UTAH
AND SOUTHWESTERN COLORADO TO CAPTURE THE OVERALL FIRE ENVIRONMENT
CONCERN.

..SYNOPSIS
A MID-LEVEL TROUGH (AND ASSOCIATED SOUTHWESTERLY MID-LEVEL FLOW) IS
FORECAST TO BE OVER CENTRAL CALIFORNIA BY THE EARLY EVENING, WITH A
SURFACE LOW CENTERED OVER THE GREAT BASIN. DEEP BOUNDARY LAYER
MIXING BENEATH THE MID-LEVEL JET, IN COMBINATION WITH A SURFACE LOW
TO THE NORTH, WILL RESULT IN CRITICAL FIRE-WEATHER CONDITIONS ACROSS
PORTIONS OF NEW MEXICO AND ARIZONA.
..WEST-CENTRAL NEW MEXICO INTO FAR EASTERN ARIZONA
20-25 MPH WINDS AND 10-15% RELATIVE HUMIDITY VALUES ARE FORECAST
OVER MUCH OF WESTERN NEW MEXICO INTO EASTERN ARIZONA, BUT MOST OF
THE RECEPTIVE FUELS (BASED ON ERC PERCENTILES) ARE CONFINED TO
CENTRAL AND SOUTHERN NEW MEXICO. THEREFORE, ONLY A RELATIVELY SMALL
AREA OF CRITICAL HIGHLIGHTS ARE FORECAST WHERE METEOROLOGICAL
CONDITIONS AND FUELS EXCEEDING THE 80TH ANNUAL PERCENTILE OVERLAP.
