   ...CRITICAL FIRE WEATHER AREA FOR SRN HIGH PLAINS...
   
   ...SYNOPSIS...
   AS AN UPPER-LEVEL TROUGH PUSHES ACROSS THE ERN CONUS...A SIGNIFICANT
   SHORT WAVE WILL DIG SWD FROM THE PACIFIC NW TOWARDS THE DESERT SW.

   PRIMARY CONDITIONS: STRONG WINDS / LOW RH / RECENT DRYNESS
   
   LOW-LEVEL SWLY FLOW WILL RAPIDLY INCREASE ON WED...ENHANCING
   DOWNSLOPE EFFECTS OFF THE SRN ROCKIES. THIS WILL RESULT IN
   WELL-ABOVE NORMAL TEMPERATURES /IN THE MIDDLE 60S TO MIDDLE
   70S/...SUPPORTING RH VALUES FALLING TO BETWEEN 12 TO 20 PERCENT.
   SUSTAINED SURFACE WINDS FROM 20 TO 30 MPH SHOULD BE COMMON DURING
   THE AFTERNOON. THE ERN EXTENT OF CRITICAL CONDITIONS INTO WRN
   OK/N-CNTRL TX IS MORE UNCERTAIN. MODEL GUIDANCE SUGGESTS MORE BACKED
   AND WEAKER LOW-LEVEL FLOW NEAR PEAK HEATING WILL MAINTAIN COOLER
   TEMPERATURES AND SUBSEQUENT MARGINAL DURATIONS OF LOW RH.
