   ...CRITICAL FIRE WEATHER AREA FOR SE NV/SRN UT AND NW/WCNTRL AZ...
   ...CRITICAL FIRE WEATHER AREA FOR FOR ISOLATED TO SCATTERED DRY
   THUNDERSTORMS FOR ERN NV/WRN UT/NW AZ...
   
   ...SYNOPSIS...
   BROAD UPPER RIDGE WILL REMAIN CENTERED OVER THE SOUTH CENTRAL STATES
   INTO WEDNESDAY. ON THE PERIPHERY OF THIS RIDGE...SCATTERED
   SHOWERS/TSTMS WILL BE COMMON THROUGH THE PERIOD ACROSS THE NRN/CNTRL
   ROCKIES...NORTHERN PLAINS/UPPER MIDWEST...AND MUCH OF THE ERN THIRD
   OF THE COUNTRY. IN THE WEST...UPPER LOW ALONG THE SRN CA COAST EARLY
   THIS MORNING WILL TRANSITION NEWD THROUGH THE DAY...REACHING THE
   CNTRL/SRN ROCKIES EARLY WEDNESDAY. STRONG MID LEVEL WINDS ASSOCIATED
   WITH THE FEATURE WILL OVERSPREAD THE LOWER COLORADO RIVER VALLEY/SRN
   GREAT BASIN TODAY...FURTHER COMPLICATING AN ALREADY HEIGHTENED FIRE
   DANGER OVER THE REGION.
   
   ...CRITICAL FIRE WEATHER AREA 1 - SE NV/SRN UT AND NW/WCNTRL AZ...
   
   PRIMARY CONDITIONS: GUSTY WINDS...HOT TEMPERATURES...LOW RH
   VALUES...ISOLD DRY LIGHTNING STRIKES
   
   COMBINATION OF GUSTY WINDS...HOT TEMPERATURES...AND PROLONGED LOW RH
   VALUES OF 10-15 PERCENT WILL PERSIST ACROSS MUCH OF SE NV/SW UT INTO
   NW/WCNTRL AZ TODAY. AS MID LEVEL JET OVERSPREADS THE REGION...SWLY
   SUSTAINED WINDS OF 20 MPH /WITH CONSIDERABLY HIGHER GUSTS/ WILL
   EXIST THROUGH THE AFTERNOON AMIDST A DEEPLY MIXED BOUNDARY LAYER. AT
   LEAST ISOLD DRY THUNDERSTORMS ARE EXPECTED OVER THE REGION THROUGH
   THE AFTERNOON...WHICH WILL POTENTIALLY LEAD TO NEW FIRE STARTS AND
   ERRATIC DOWNBURST WINDS.
   
   ...CRITICAL FIRE WEATHER AREA 2 - ERN NV/WRN UT/NW AZ...
   
   PRIMARY CONDITIONS: ISOLATED TO SCATTERED DRY THUNDERSTORMS
   
   ISOLATED TO SCATTERED DRY THUNDERSTORMS ARE EXPECTED THROUGH THE
   AFTERNOON FROM ERN NV/NW AZ INTO WRN UT. COMBINATION OF DRY
   LIGHTNING AND HIGH LIGHTNING IGNITION EFFICIENCIES WILL LIKELY
   CONTRIBUTE TO ADDITIONAL FIRE STARTS TODAY. RELATIVELY QUICK
   MOVEMENT OF THE STORMS TO THE NORTHEAST WILL TEND TO LIMIT RAINFALL
   ACCUMULATIONS. ASIDE FROM THE POTENTIAL FOR ADDITIONAL FIRE
   IGNITIONS...DEEPLY MIXED BOUNDARY LAYER WILL LEAD TO DOWNBURSTS AND
   ASSOCIATED GUSTY/ERRATIC WINDS...WHICH WILL FURTHER ADVERSELY IMPACT
   ONGOING WILDFIRES.
   
   ...SRN WY/ERN UT/WRN CO...
   GUSTY W/SW WINDS ARE EXPECTED ALONG A COLD FRONT FROM SRN WY/NE UT
   INTO WRN CO. ALONG/AHEAD OF THE FRONT...RELATIVELY WELL-MIXED
   BOUNDARY LAYER AND STRONG LOW TO MID LEVEL WIND FIELD WILL LEAD TO
   SUSTAINED SWLY WINDS OF 20-25 MPH...WITH POTENTIAL FOR GUSTS TO
   30-40 MPH /ESPECIALLY ACROSS WY/. IN SPITE OF THE GUSTY
   WINDS...CLOUD COVER AND MARGINAL RH VALUES AROUND 15 PERCENT WILL
   TEND TO SOMEWHAT LIMIT THE CRITICAL FIRE WEATHER THREAT.
   ADDITIONALLY...POTENTIAL WILL EXIST FOR ISOLD DRY TSTMS ACROSS ERN
   UT/WRN CO.
   
   ...NM...
   OWING TO SUFFICIENT LIFT/INSTABILITY AND MARGINAL MOISTURE
   PROFILES...ISOLD DRY TSTMS AND DOWNBURSTS WILL BE POSSIBLE
   TODAY...NAMELY ACROSS WRN/CNTRL PORTIONS OF NM.

   VALID 291200Z - 301200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   OVERALL PATTERN ON WEDNESDAY HIGHLIGHTED BY POTENT UPPER TROUGH
   TRANSITIONING EWD ACROSS THE NRN PLAINS/UPPER MIDWEST. IN THE WAKE
   OF THIS FEATURE...RISING HEIGHTS AND A TRANSITION TO A LOW AMPLITUDE
   WESTERLY UPPER FLOW IS EXPECTED ACROSS THE WRN STATES.
   OTHERWISE...SCATTERED SHOWERS/TSTMS WILL REMAIN PREVALENT ACROSS THE
   NRN PLAINS/UPPER MIDWEST AND ERN THIRD OF THE CONUS.
   
   ...NRN AZ/SRN UT/WRN NM/WRN CO...
   LIGHTER WIND SPEEDS ARE EXPECTED ACROSS THE REGION IN WAKE OF
   DEPARTED UPPER IMPULSE...WITH RISING HEIGHTS AND A PROGRESSIVELY
   WESTERLY UPPER FLOW REGIME. BROAD SCALE W/SW WINDS SHOULD GENERALLY
   BE 15 MPH OR LESS...ALTHOUGH PERHAPS MARGINALLY STRONGER ACROSS SW
   CO/NW NM. IN SPITE OF THE LIGHTER BROAD SCALE WINDS...HOT/WELL-MIXED
   BOUNDARY LAYER WITH LOW RH VALUES WILL NEVERTHELESS IMPACT ANY
   ONGOING FIRES WITH ENHANCED FIRE GROWTH POTENTIAL.
   
   ...SRN/ERN KS AND NRN OK...
   SW WINDS /SUSTAINED 15-20 MPH/ ARE EXPECTED WEDNESDAY AFTERNOON
   ACROSS SRN/ERN KS AND NRN OK AHEAD OF A COLD FRONT. IN SPITE OF
   AFTERNOON TEMPERATURES AROUND/ABOVE 100 F...AMPLE BOUNDARY LAYER
   MOISTURE WILL CONTRIBUTE TO RH VALUES SUFFICIENTLY ABOVE CRITICAL
   THRESHOLDS.
