   VALID 061200Z - 071200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR THE PLAINS OF ERN CO AND NERN
   NM...SW NEB...WRN KS...AND THE TX/OK PANHANDLE...
   
   ...SYNOPSIS...
   A STRONG UPPER LEVEL TROUGH WILL DROP SOUTH ALONG THE WEST COAST ON
   FRIDAY...WHILE A RIDGE CONTINUES TO SHIFT EAST ACROSS THE PLAINS. A
   SHORTWAVE TROUGH INITIALLY LOCATED OVER THE DESERT SW WILL EJECT NE
   INTO THE CENTRAL PLAINS DURING THE AFTERNOON IN RESPONSE TO THE
   DIGGING PACIFIC DISTURBANCE. THIS WILL CAUSE THE UPPER LEVEL RIDGE
   TO BREAK DOWN...WITH MODERATELY STRONG WEST-SOUTHWESTERLY MID LEVEL
   FLOW SPREADING EAST ACROSS THE CENTRAL/SOUTHERN HIGH PLAINS.
   MEANWHILE...SURFACE LOW PRESSURE WILL EMERGE OVER THE NRN
   PLAINS...WITH A TROUGH AXIS MOVING EAST INTO THE HIGH PLAINS. WELL
   ABOVE NORMAL TEMPERATURES WILL DEVELOP ALONG THIS TROUGH...WITH LOW
   RH VALUES AND STRENGTHENING WINDS SUPPORTING CRITICAL FIRE WEATHER
   CONDITIONS.
   
   ...CRITICAL FIRE WEATHER AREA - THE PLAINS OF ERN CO AND NERN
   NM...SW NEB...WRN KS...AND THE TX/OK PANHANDLE...
   
   PRIMARY CONDITIONS: ABOVE NORMAL TEMPERATURES...LOW
   RH...WINDS...DEVELOPING DROUGHT
   
   CURRENT MODEL GUIDANCE INDICATES A SHORTWAVE TROUGH WILL MOVE FROM
   NE CO INTO CENTRAL NEB DURING THE 18Z/FRI-00Z/SAT TIME PERIOD. AS
   THIS OCCURS...LOW LEVEL WINDS WILL RESPOND BY VEERING TO
   WSW...RESULTING IN A SURFACE TROUGH AXIS MOVING EAST ACROSS WRN KS
   INTO PORTIONS OF THE TX PANHANDLE. ALONG AND WEST OF THE
   TROUGH...DEEP VERTICAL MIXING WILL OCCUR...WITH SUSTAINED WINDS OF
   20-30 MPH GUSTING UP TO 30-40 MPH. EARLY MORNING SURFACE
   OBSERVATIONS SHOW DEWPOINTS IN THE SINGLE DIGITS TO LWR TEENS ACROSS
   MUCH OF THE CRITICAL OUTLOOK AREA...WITH LITTLE MODIFICATION OF THIS
   DRY AIRMASS EXPECTED THROUGH THE AFTERNOON. IN ADDITION...DAYTIME
   HIGH TEMPERATURES ARE FORECAST TO BE IN THE 60S AND 70S...WHICH WILL
   PROMOTE CRITICALLY LOW RH VALUES /BELOW 20 PERCENT/. GIVEN THE
   PRESENCE OF ABNORMALLY DRY TO MODERATE DROUGHT CONDITIONS ACROSS
   MUCH OF THE SRN AND CENTRAL HIGH PLAINS...A LARGE CRITICAL FIRE
   WEATHER AREA IS EXPECTED.

   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER LEVEL TROUGH WILL CONTINUE TO DIG INTO SRN CA ON D2...WHILE
   A RIDGE BUILDS FROM THE SRN HIGH PLAINS INTO THE CENTRAL ROCKIES.
   SOUTHERLY LOW LEVEL FLOW WILL BE INDUCED AHEAD OF THE UPPER
   DISTURBANCE...TRANSPORTING AN INCREASINGLY MOIST AND HUMID AIRMASS
   NORTHWARD INTO THE PLAINS.
   
   ...FAR W TX AND THE BIG BEND REGION...
   A DEEPLY MIXED BOUNDARY LAYER AIRMASS IS FORECAST TO DEVELOP OVER
   FAR W TX/BIG BEND REGION ON SAT/D2 AS TEMPERATURES WARM INTO THE 70S
   DURING THE AFTERNOON. SHORTWAVE RIDGING OCCURRING OVER THE AREA AND
   A WEAK SURFACE PRESSURE GRADIENT WILL RESULT IN SUB-OPTIMAL WIND
   SPEEDS...PRECLUDING A CRITICAL OUTLOOK.
