   VALID 041200Z - 051200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR THE SOUTHERN HIGH PLAINS...
   
   ...SYNOPSIS...
   A STRONG FULL LATITUDE UPPER TROUGH WILL MOVE THROUGH THE SWRN
   STATES AND ROCKIES TODAY.  AT THE SURFACE...LOW PRESSURE WILL FORM
   IN CNTRL PLAINS...RESULTING IN STRONG SWLY SURFACE WINDS FROM SRN NM
   TO SRN KS.  GIVEN THE VERY DRY AND MILD AIRMASS ACROSS THE SRN HIGH
   PLAINS...A BROAD AREA OF CRITICAL FIRE WEATHER CONDITIONS WILL
   DEVELOP THIS AFTERNOON.  FARTHER TO THE WEST...SEASONABLY STRONG
   SURFACE HIGH PRESSURE WILL BUILD SWD INTO THE GREAT BASIN TONIGHT. 
   THIS SHOULD INITIATE A PERIOD OF OFFSHORE FLOW FOR CNTRL/SRN
   CA...ALTHOUGH THE COMBINATION OF HUMIDITY/WIND IS EXPECTED TO REMAIN
   NONCRITICAL.  IN THE ERN CONUS...ABOVE NORMAL TEMPERATURES AND A
   RELATIVELY MOIST LOW LEVEL AIRMASS ARE FOUND BENEATH A STRENGTHENING
   UPPER RIDGE.
   
   ...CRITICAL FIRE WEATHER AREA - ERN NM/WRN TX/WRN OK/FAR SWRN KS...
   
   PRIMARY CONDITIONS: VERY WINDY WITH LOW RH
   
   AS A SURFACE CYCLONE FORMS OVER SWRN KS...WINDY CONDITIONS /SWLY 15
   TO 30 MPH WITH HIGHER GUSTS/ DEVELOP FROM SRN NM TO SRN KS.  THE
   POTENTIAL FOR VERY LOW RH EXISTS WITHIN THIS CORRIDOR...AS SUBSIDING
   SWLY FLOW KEEPS SURFACE DEWPOINTS IN THE TEENS/LOWER 20S AND PUSHES
   MAXIMUM TEMPERATURES INTO THE UPPER 60S AND 70S.  MINIMUM RH WILL
   FALL TO BETWEEN 10 TO 20 PERCENT...ALTHOUGH WRN PORTIONS OF THE
   CRITICAL AREA MAY EXPERIENCE WINDS SHIFTING TO NWLY AND RAPIDLY
   FALLING TEMPERATURES AS A COLD FRONT ENCROACHES UPON THE AREA LATE
   THIS AFTERNOON.  THE ERN EXTENT OF THE CRITICAL AREA OVER
   CENTRAL/SRN OK IS NEAR THE EXPECTED LOCATION OF THE DRYLINE...WHILE
   FARTHER SOUTH THE ERN EXTENT OF THE CRITICAL AREA IS WHERE THE
   WEAKER PRESSURE GRADIENT SUPPORTS SUSTAINED WINDS GENERALLY LESS
   THAN 20 MPH.

   VALID 051200Z - 061200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR SOUTH CENTRAL TEXAS...
   
   ...SYNOPSIS...
   A PROGRESSIVE PATTERN DEVELOPS ACROSS THE CONUS TUESDAY...WITH A
   LARGE UPPER TROUGH MOVING FROM THE SRN PLAINS TO THE MID MISSISSIPPI
   VALLEY...AND ANOTHER MODERATELY STRONG UPPER TROUGH MOVING THROUGH
   THE PACIFIC NORTHWEST.  AT THE SURFACE...A COLD FRONT EXTENDS FROM
   THE ERN GREAT LAKES REGION TWD THE TX COAST...WITH AN EXTENSIVE AREA
   OF SHOWERS AND THUNDERSTORMS FROM THE LOWER MISSISSIPPI VALLEY TO
   NEW ENGLAND.  IN THE WAKE OF THE AFOREMENTIONED UPPER TROUGH/SURFACE
   COLD FRONT... MODERATE NWLY WINDS AND DRY AIR SUPPORT CRITICAL FIRE
   WEATHER CONDITIONS OVER PORTIONS OF SOUTH TX.  SURFACE HIGH PRESSURE
   IN THE GREAT BASIN MAINTAINS OFFSHORE FLOW OVER CNTRL/SRN
   CA...ALTHOUGH THE COMBINATION OF MOIST ANTECEDENT CONDITIONS AND A
   RELATIVELY WEAK PRESSURE GRADIENT SHOULD KEEP CONDITIONS
   NONCRITICAL.
   
   ...CRITICAL FIRE WEATHER AREA - SOUTH CENTRAL TEXAS...
   
   PRIMARY CONDITIONS: MODERATE NWLY WINDS AND LOW RH
   
   THE POSTFRONTAL AIRMASS OVER SCNTRL TX WILL BRING A PERIOD OF
   CRITICAL FIRE WEATHER CONDITIONS TO THE AREA TUESDAY AFTERNOON. 
   WINDS WILL BE NWLY AT 15 TO 25 MPH /WITH HIGHER GUSTS/ AS SURFACE RH
   FALLS TO NEAR 15 PERCENT.  DESPITE THE COOLER AIRMASS...MAXIMUM
   TEMPERATURES SHOULD STILL CLIMB INTO THE 60S AND LOWER 70S...WITH
   CRITICAL CONDITIONS EXPECTED FOR SEVERAL HOURS.  JUST EAST OF THE
   CRITICAL AREA...RH AT OR BELOW 20 PERCENT MAY BRIEFLY EXTEND TO THE
   TX COASTAL PLAIN AS THE SURFACE COLD FRONT MOVES OFFSHORE LATE IN
   THE AFTERNOON.  HOWEVER..THE SHORT DURATION OF LOW RH COMBINED WITH
   SLIGHTLY LESS WIND /BECOMING NWLY AT 15 TO 20 MPH/ SHOULD KEEP
   CRITICAL CONDITIONS MARGINAL AND/OR BRIEF NEAR THE COASTAL PLAIN.
