   ...CRITICAL FIRE WEATHER AREA FOR SRN AND ERN NV...NWRN AZ...MUCH OF
   UT AND WY...FAR WRN SD/NEB...NWRN CO...
   
   ...SYNOPSIS...
   A LARGE UPPER TROUGH WILL AMPLIFY ACROSS THE WRN STATES WITH BROAD
   AREA OF STRONG WINDS FROM THE GREAT BASIN INTO THE PLAINS STATES. A
   COLD FRONT WILL EXTEND FROM WRN MT INTO WRN NV THIS AFTERNOON...WITH
   SCATTERED SHOWERS AND THUNDERSTORMS AND A WIND SHIFT IN ASSOCIATION
   WITH THIS FRONT. MEANWHILE...ANOTHER UPPER TROUGH WILL AFFECT THE
   NERN STATES WITH COOL AND WET WEATHER...WHILE A DRY AREA OF HIGH
   PRESSURE BRINGS LOW RH TO THE MS VALLEY AND DEEP SOUTH.
   
   ...CRITICAL FIRE WEATHER AREA - SRN AND ERN NV...NWRN AZ...MUCH OF
   UT AND WY...FAR WRN SD/NEB...NWRN CO...
   
   PRIMARY CONDITIONS: VERY STRONG WINDS...LOW RH
   
   WINDS WILL INCREASE THROUGHOUT THE DAYTIME AHEAD OF A COLD FRONT
   WITH SPEEDS OF 20-40 MPH SUSTAINED AND HIGHER GUSTS. DESPITE
   RELATIVELY COOL TEMPERATURES...MIN RH SHOULD DROP TO NEAR 15 PERCENT
   IN MANY AREAS. THE WARMEST TEMPERATURES WILL OCCUR ACROSS THE LOWER
   CO RIVER VALLEY WITH HIGHS IN THE 90S...BUT WILL ONLY BE IN THE 70S
   OVER THE GREAT BASIN AND NRN ROCKIES. WARMER WEATHER WILL ALSO EXIST
   ACROSS THE PLAINS STATES...WITH 80S LIKELY INTO WRN SD/NEB AND RH
   NEAR 15-20 PERCENT. A MIXTURE OF WET AND DRY THUNDERSTORMS ARE ALSO
   LIKELY FROM NRN NV ACROSS UT DURING THE AFTERNOON AND INTO THE
   OVERNIGHT HOURS.
   
   ...NRN AL/GA...TN...WRN CAROLINAS...
   HIGH PRESSURE WILL SETTLE INTO THE AREA WITH COOL BUT DRY NLY WINDS
   AROUND 15 MPH WITH GUSTS TO AROUND 20 MPH. MIN RH VALUES ARE
   EXPECTED TO BE MAINLY IN THE 25-30 PERCENT RANGE WHILE TEMPERATURES
   RISE INTO THE 80S. STEEP LOW LEVEL LAPSE RATES/DEEP MIXING LAYERS
   COMBINED WITH THE DRY AND BREEZY WEATHER MAY YIELD LOCALLY CRITICAL
   FIRE CONDITIONS WHERE FUELS REMAIN DRY.
   
   ...WRN NV INTO SWRN MT...
   A COLD FRONT WILL EXTEND FROM WRN MT ACROSS WRN ID INTO WRN NV THIS
   AFTERNOON. AHEAD OF THIS FRONT...WINDS WILL BE SWLY AT 15-25 MPH
   WITH HIGHER GUSTS. RELATIVELY COOL TEMPERATURES IN THE 60S AND 70S
   WILL LIKELY ONLY ALLOW FOR MARGINALLY LOW RH VALUES OF 15-20
   PERCENT. HOWEVER...THE FRONTAL PASSAGE WILL INCLUDE A WIND SHIFT TO
   NWLY AT 15-25 MPH. CHANCES OF PRECIPITATION ALONG THIS FRONT WILL
   FURTHER MITIGATE OVERALL FIRE THREAT.

   VALID 291200Z - 301200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A POWERFUL UPPER TROUGH AND SURFACE FRONT WILL CONTINUE EWD ACROSS
   THE CNTRL/NRN ROCKIES AND INTO THE PLAINS ON SATURDAY WITH VERY
   STRONG AND SHIFTING WINDS ALONG WITH THUNDERSTORMS. MEANWHILE...AN
   EXPANSIVE AREA OF HIGH PRESSURE WILL CONTINUE TO BRING MILD AND DRY
   WEATHER TO MUCH OF THE SERN STATES WITH MARGINAL AFTERNOON FIRE
   THREAT.
   
   ...ERN CO AND WY...WRN SD AND NEB...
   VERY STRONG SWLY WINDS OF 20-30 MPH WITH HIGHER GUSTS WILL BEGIN
   RIGHT AFTER SUNRISE AND WILL PERSIST THROUGHOUT THE DAY. A COLD
   FRONT IS EXPECTED TO STRETCH FROM WRN SD INTO WRN NEB AND NERN CO BY
   AFTERNOON...AND THIS FRONT WILL BRING WITH IT AN ABRUPT WIND SHIFT
   TO NWLY AT 20-30 MPH. ALTHOUGH VERY WINDY....INDICATIONS ARE THAT RH
   LEVELS WILL NOT BE PARTICULARLY LOW...RANGING FROM 20-30 PERCENT
   AVERAGE. IN ADDITION...THUNDERSTORMS WILL OCCUR ALONG THE FRONT. THE
   BEST CHANCE OF A DRY FRONTAL PASSAGE APPEARS TO BE NERN CO...AND
   PORTIONS OF THIS AREA COULD BE UPGRADED TO CRITICAL ONCE TIMING OF
   FRONTAL PASSAGE BECOMES MORE CLEAR.
   
   ...NERN AZ INTO FOUR CORNERS VICINITY...
   STRONG WINDS WILL PERSIST INTO SATURDAY WITH SUSTAINED SPEEDS
   AVERAGING 20-25 MPH WITH HIGHER GUSTS. RH LEVELS ARE FORECAST TO BE
   MARGINAL...AT 15-20 PERCENT WITH RELATIVELY COOL TEMPERATURES.

   MIN RH SHOULD DROP WELL INTO THE 20 PERCENT RANGE WITH SOME VALUES
   INTO THE TEENS OVER THE WRN CAROLINAS...RESULTING IN A MARGINAL FIRE
   THREAT.
