   VALID 081200Z - 091200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR TX BIG BEND AND PARTS OF THE TX
   PECOS RIVER VALLEY...
   
   ...SYNOPSIS...
   VIGOROUS CLOSED BUT PROGRESSIVE UPPER SYSTEM WILL MOVE FROM THE SRN
   ROCKIES INTO THE CNTRL PLAINS AS AN UPPER TROUGH MOVES INTO THE W
   COAST STATES.  WIDESPREAD CLOUDS AND RAINFALL WILL SPREAD/DEVELOP
   NEWD OVER THE SRN PLAINS IN CONJUNCTION WITH SYSTEM EJECTING FROM
   THE SWRN U.S.  AT THE SURFACE...CYCLOGENESIS WILL OCCUR FROM THE
   TX/OK PANHANDLES EWD ALONG THE KS/OK BORDER AS A COLD FRONT PUSHES
   EWD OVER THE SRN PLAINS.  FURTHER E...A DRY AIRMASS IN PLACE OVER
   THE SERN U.S. WILL LEAD TO LOW MIN RH DURING PEAK HEATING.
   
   ...CRITICAL FIRE WEATHER AREA - TX BIG BEND AND PARTS OF THE TX
   PECOS RIVER VALLEY...
   
   PRIMARY CONDITIONS: STRONG WINDS / LOWER RH
   
   STRONG FLOW FIELDS ALOFT /H7 WINDS /30-45 KTS/ WILL QUICKLY
   OVERSPREAD THE REGION EARLY MONDAY LEADING TO STRONG SWLY TO WLY
   SUSTAINED SURFACE WINDS.  STEEP LAPSE RATES IN THE BOUNDARY LAYER
   WILL PROMOTE DOWNWARD MOMENTUM TRANSPORT AND LEAD TO SUSTAINED WINDS
   OF 20-35 MPH /STRONGER NEAR I-20/ DURING THE AFTERNOON HOURS.  00Z
   ECMWF OUTPUT INDICATES LOWER RH /TEENS/ THAN BOTH THE 06Z NAM AND
   00Z GFS MODELS.  AS SUCH...THE MAIN FACTOR LIMITING THE PERCEIVED
   CRITICAL THREAT AREA IS DUE TO UNCERTAINTY REGARDING THE STRENGTH OF
   SURFACE HEATING AND DRY AIR IMPACTING THE MAGNITUDE/DURATION OF LOW
   MIN RH /15 PERCENT/.
