   CORRECTED FOR WORDING
   
   ...CRITICAL FIRE WEATHER AREA FOR NWRN AZ / SRN UT / SERN NV...
   
   ...SYNOPSIS...
   UPPER RIDGE WILL BUILD OVER THE SRN ROCKIES ON TUESDAY...WITH FAST
   FLOW AROUND PERIPHERY AHEAD OF WEAK UPPER LOW OVER CENTRAL CA. SOME
   MOISTENING WILL OCCUR OVER THE SWRN STATES DUE TO PROLONGED SLY FLOW
   ALOFT...BUT RH WILL STILL BE LOW IN MANY AREAS. STRONG WINDS WILL
   OCCUR OVER WY WITH JET STREAM OVERHEAD...BUT RH WILL NOT BE
   CRITICALLY LOW WITH COOL TEMPERATURES.
   
   ...CRITICAL FIRE WEATHER AREA 1 - NWRN AZ / SRN UT / SERN NV...
   
   PRIMARY CONDITIONS: MODERATE SWLY WINDS / LOW RH
   
   GUSTY SLY WINDS WILL PERSIST DUE TO APPROACHING WEAK UPPER LOW AND
   PRESENCE OF UPPER RIDGE TO THE SE. SUSTAINED SLY WINDS NEAR 20 MPH
   APPEAR LIKELY WITH HIGHER GUSTS. RH LEVELS WILL BE UP FROM PREVIOUS
   DAYS...BUT STILL LOW AT 10-15 PERCENT. HAINES INDEX WILL LIKELY BE
   MDT DURING THE AFTERNOON...AND GUSTY WINDS WILL PERSIST IN THE HIGH
   TERRAIN OVERNIGHT.
   
   IN ADDITION...ISOLATED DRY THUNDERSTORMS WILL BE LIKELY OVER THE NRN
   HALF OF THE CRITICAL AREA...WITH STORMS FORMING ON SW FACING SLOPES
   AND MOVING NEWD. DRY SUB CLOUD LAYERS AND FAST FLOW ALOFT SUGGEST
   LITTLE IF ANY RAIN WILL REACH THE GROUND.
   
   ...CENTRAL AND ERN NV / WRN UT...
   SLIGHT COOLING ALOFT WITH WEAK UPPER LOW OVER CA ALONG WITH SWLY
   UPSLOPE FLOW WILL ALLOW FOR SCATTERED THUNDERSTORMS TO OCCUR DURING
   THE AFTERNOON. STRONG MEAN WIND SPEEDS ABOVE CLOUD BASE SUGGEST
   STORMS WILL MOVE QUICKLY TO THE NE...PROVIDING LITTLE OPPORTUNITY
   FOR RAINFALL AS AIR MASS WILL REMAIN QUITE DRY IN THE LOW LEVELS.
   GIVEN RECENT TENDENCY FOR AIR MASS TO BE DRIER THAN FORECAST...WILL
   WAIT UNTIL NEXT DAY ONE FORECAST TO DETERMINE IF CRITICAL CONDITIONS
   FOR DRY LIGHTNING WILL OCCUR.
   
   ...WY / NWRN CO...
   IT WILL BE WINDY ON TUESDAY AS STRONG UPPER TROUGH PASSES JUST TO
   THE NORTH. STRONG WLY DOWNSLOPE FLOW WILL MIX TO THE SURFACE
   PROVIDING SUSTAINED SPEEDS OF 20-25 MPH WITH HIGHER GUSTS OF 30-40
   MPH. RH LEVELS ARE NOT EXPECTED TO BE VERY LOW HOWEVER...NEAR 20
   PERCENT WITH COOL TEMPERATURES IN THE 70S. SOME LOCATIONS COULD SEE
   RH AS LOW AS 15 PERCENT...THE MOST LIKELY AREA BEING SOUTH CENTRAL
   INTO SERN WY.
