   VALID 121200Z - 131200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR EXTREME NERN NV/WRN WY/NRN UT/NW
   CO...
   
   ...SYNOPSIS...
   EARLY MORNING SATELLITE LOOPS SHOW LEAD SHORTWAVE TROUGH ENTERING
   SASKATCHEWAN WITH ANOTHER IMPULSE AND ASSOCIATED JET MAX OVER THE
   PACIFIC NORTHWEST. WRN LARGE SCALE TROUGH WILL DEEPEN TODAY ACROSS
   THE NRN ROCKIES IN RESPONSE TO HEIGHT FALLS...AS TROUGH AXIS SHIFTS
   EWD. SFC COLD FRONT WILL MOVE ACROSS THE GREAT BASIN/NRN UT AND
   WCNTRL WY BY AFTN/EVENING WITH STRONG WINDS/WIND SHIFT NEAR THE
   FRONTAL ZONE. FARTHER EAST ACROSS THE NRN PLAINS...DEEPENING LEE
   TROUGH WILL INDUCE A STRONG SLY FLOW ACROSS THE SRN/CNTRL PLAINS.
   
   ...CRITICAL FIRE WEATHER AREA - EXTREME NERN NV/WRN WY/NRN UT/NW
   CO...
   
   PRIMARY CONDITIONS: SUSTAINED WLY WINDS FROM 20-25 MPH...RH READINGS
   
   SUSTAINED WLY WINDS 20-25 MPH/MIN RH VALUES BELOW 15 PERCENT/ISOLD
   DRY LIGHTNING
   
   CRITICAL FIRE WEATHER CONDITIONS ARE EXPECTED TO DEVELOP TODAY
   ACROSS PORTIONS OF NRN NV/SRN ID/NRN UT AND MUCH OF WRN/CNTRL WY.
   MID LEVEL SPEED MAX /AROUND 50-55 KT/ WILL ARRIVE IN THE ERN GREAT
   BASIN BY AFTN. VERY STEEP LAPSE RATES WILL ALLOW THE BOUNDARY LAYER
   TO BECOME DEEPLY MIXED...WITH THE POTENTIAL FOR STRONG/GUSTY WINDS.
   SUSTAINED WINDS OF 20-30 MPH WITH HIGHER GUSTS ARE LIKELY WITH LARGE
   TEMP/DEWPOINT DEPRESSION VALUES...ESPECIALLY IN THE LOWER
   ELEVATIONS. WINDS WILL SHIFT FROM SW AHEAD OF THE FRONT TO THE N/NW
   BEHIND THE FRONT...POSING A THREAT FOR ONGOING WILDFIRE OPERATIONS. 
   
   
   SCATTERED SHOWERS/TSTMS WILL BE POSSIBLE ACROSS MUCH OF ID/WY AND
   ERN UT BOTH ASSOCIATED WITH THE COLD FRONT AND INCREASED LARGE SCALE
   ASCENT FROM THE UPPER TROUGH. PROFILES LOOK MOST FAVORABLE FOR DRY
   LIGHTNING ACROSS ERN ID /UPPER SNAKE RIVER PLAIN/ AND ERN UT.
   
   ...CNTRL HIGH PLAINS...
   VERY STRONG SLY WINDS WILL INCREASE RISKS FOR WIND DRIVEN FIRES
   TODAY. SUSTAINED 15-25 MPH WINDS WILL DEVELOP INVOF LEE TROUGH AND
   RH VALUES WILL BE RELATIVELY LOW /LESS THAN 20 PERCENT IN SOME
   LOCATIONS/. IN ADDITION...WINDS WILL SHIFT BEHIND COLD FRONT ACROSS
   NEB PANHANDLE IN THE LATE MORNING/EARLY AFTN. SCATTERED TSTMS WITH
   THE POTENTIAL FOR STRONG/SVR WIND GUSTS ARE POSSIBLE AS WELL.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0412 AM CDT SAT AUG 12 2006
   
   VALID 131200Z - 141200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   UPPER TROUGH NOW OVER THE NORTHWEST WILL MOVE EAST ACROSS THE NRN
   PLAINS ON SUNDAY AS A SUBTROPICAL ELY WAVE AFFECTS THE SRN PLAINS.
   MAIN SFC LOW PRESSURE SYSTEM WILL BE ACROSS THE NCNTRL PLAINS SUNDAY
   MORNING...AND WILL MOVE EWD TO NEAR THE IA/NEB BORDER BY AFTN. COLD
   FRONT WILL BE THE FOCUS FOR WIDESPREAD SHOWERS/TSTMS FROM THE UPPER
   MIDWEST INTO ERN NEB. STRONG WINDS SOUTH OF THE FRONT MAY INCREASE
   THE FIRE THREAT ACROSS THE SRN PLAINS GIVEN LOW HUMIDITY AND LONG
   TERM DROUGHT.
   
   ...SRN PLAINS...
   HIGH TEMPS ARE EXPECTED TO BE 100-105 ON SUNDAY WITH GUSTY WINDS.
   MINIMUM RH VALUES WILL LIKELY RANGE FROM 20-25 PERCENT GIVEN
   EXPECTED DEWPOINTS IN THE LOW/MID 60S. ISOLD TSTMS ARE ALSO POSSIBLE
   ALTHOUGH WIDESPREAD RAIN IS NOT EXPECTED. CHANCES FOR RAIN INCREASE
   ON MONDAY AS FRONT APPROACHES.
