   ...CRITICAL FIRE WEATHER AREA FOR UT/SRN WY/WRN AND CNTRL CO/NE
   AZ/NW NM...
   
   ...SYNOPSIS...
   WRN STATES UPPER TROUGH WILL MIGRATE EWD TODAY INTO THE
   INTERMOUNTAIN REGION...WHILE SUBTROPICAL RIDGE REMAINS DOMINANT
   FEATURE ACROSS THE SE STATES. EXTENSIVE FRONTAL BOUNDARY WILL EXTEND
   FROM THE NE STATES INTO THE CNTRL PLAINS/ROCKIES.
   
   ...CRITICAL FIRE WEATHER AREA 1 - ERN NV/UT/FAR WRN CO/AZ/SE CA...
   
   PRIMARY CONDITIONS: VERY STRONG S/SW WINDS
   
   VERY STRONG S/SW WINDS OF 20-35 MPH /WITH SIGNIFICANTLY HIGHER GUSTS
   TO 40-50 MPH/ ARE EXPECTED TODAY FROM THE ERN GREAT BASIN TOWARD THE
   FOUR CORNERS AREA ALONG/AHEAD OF UPPER TROUGH AND ASSOCIATED COLD
   FRONT. SCENARIO SUPPORTED BY UNIDIRECTIONAL WIND FIELDS/MID LEVEL
   WIND SPEEDS OF 40-50 KTS AMIDST DEEPLY MIXED BOUNDARY LAYER. WITH
   TEMPERATURES EXPECTED TO BE AROUND/ABOVE SEASONAL AVERAGES...RH
   VALUES WILL BE AROUND/BELOW CRITICAL THRESHOLDS /10-15 PERCENT/ THIS
   AFTERNOON.
   
   ...CRITICAL FIRE WEATHER AREA 2 - UT/SRN WY/WRN AND CNTRL CO/NE
   AZ/NW NM...
   
   PRIMARY CONDITIONS: SCATTERED DRY TSTMS WITH LOCALLY GUSTY/ERRATIC
   WINDS
   
   OVERALL DYNAMIC/THERMODYNAMIC PATTERN APPEARS FAVORABLE FOR AT LEAST
   SCATTERED DRY TSTMS TODAY FROM THE ERN GREAT BASIN THROUGH THE FOUR
   CORNERS REGION. BROAD AREA OF DYNAMIC LIFT WILL OVERSPREAD THE
   REGION ALONG/AHEAD OF WRN STATES UPPER TROUGH. 00Z OBSERVED AND
   FORECAST SOUNDINGS SUGGEST PRECIPITABLE WATER VALUES OF 0.50 INCH OR
   LESS ACROSS A BROAD AREA FROM THE ERN GREAT BASIN THROUGH THE FOUR
   CORNERS.
   
   BROAD LARGE SCALE LIFT...COMBINED WITH SUFFICIENT MID LEVEL MOISTURE
   AND INSTABILITY...SUGGESTS SCATTERED /OR EVEN NUMEROUS/ TSTMS WILL
   DEVELOP THIS AFTERNOON/EARLY EVENING. VERY DRY SUB-CLOUD LAYER
   /INVERTED-V PROFILES/ AND FAVORABLE STORM MOTIONS WILL PROMOTE A
   PREDOMINANCE OF DRY TSTMS...WITH HEIGHTENED POTENTIAL FOR FIRE
   IGNITIONS AMIDST ANTECEDENT DRY CONDITIONS. IN ADDITION TO ALREADY
   STRONG AMBIENT WIND FIELDS...EVAPORATIVE COOLING OWING TO DRY
   SUB-CLOUD LAYER WILL SUPPORT STRONG DOWNDRAFTS AND LOCALLY
   ENHANCED/ERRATIC WINDS IN VICINITY OF TSTMS.
