   VALID 011200Z - 021200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   UPPER LEVELS ACROSS THE NATION WILL BEGIN A PATTERN CHANGE DURING
   DAY ONE...AS UPPER RIDGING OVER THE WEST WILL BE REPLACED BY UPPER
   TROUGHING BY THE END OF THE PERIOD. FURTHER EAST OVER THE
   PLAINS...UPPER TROUGHING WILL BE REPLACED BY UPPER RIDGING MOVING
   OUT OF THE ROCKIES. THE SENSIBLE RESULT AT THE SURFACE WILL BE AN
   EWD SHIFT OF SURFACE HIGH PRESSURE FROM THE PLAINS INTO THE ERN
   STATES...AND LEE TROUGH DEVELOPMENT OVER THE HIGH PLAINS. THIS WILL
   AID IN A WARM-UP COMMENCING OVER THE PLAINS REGION TODAY. NO AREAS
   OF CRITICAL FIRE WEATHER CONDITIONS ARE ANTICIPATED ACROSS THE
   NATION TODAY AS WINDS ARE FORECAST TO BE GENERALLY WEAK WHERE LOW RH
   READINGS WILL BE PRESENT /FROM CA EWD INTO THE PLAINS/.
   
   ...SOUTHERN CA...
   WITH THE DEVELOPMENT OF A BROAD UPPER TROUGH OVER THE
   WEST...OFFSHORE FLOW EARLY THIS MORNING WILL TURN ONSHORE BY THIS
   AFTERNOON. HOWEVER MIN RH READINGS WILL REMAIN LOW /10-20 PERCENT/
   IN INTERIOR VALLEYS AND MTNS. GIVEN RELATIVELY LIGHT OFFSHORE WINDS
   EXPECTED EVEN AT 12Z /GENERALLY 15-20 MPH/...A CRITICAL FIRE WEATHER
   THREAT IS NOT ANTICIPATED TODAY.
   
   ...SOUTHERN TX...
   IN THE WAKE OF A STRONG COLD FRONT...MUCH DRIER AIR HAS FILTERED
   INTO THE REGION EARLY THIS MORNING. DEWPTS TODAY WILL BE IN THE
   30S/40S...WITH MIN RH READINGS FROM 20-30 PERCENT. SUSTAINED NLY
   WINDS WILL BE STRONGEST THIS MORNING...BUT SPEEDS AT TIMES AROUND 20
   MPH CAN BE EXPECTED THIS AFTERNOON AS RH READINGS FALL BELOW 25
   PERCENT FOR A FEW HOUR PERIOD. THE MAIN LIMITING FACTORS FOR THE
   LACK OF CRITICAL FIRE WEATHER CONDITIONS WILL BE THE MARGINAL WINDS
   SPEEDS DURING THE AFTERNOON COMBINED WITH SOAKING RAINS THAT COVERED
   THE WHOLE AREA YESTERDAY.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0337 AM CST TUE NOV 01 2005
   
   VALID 021200Z - 031200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   UPPER TROUGHING WILL BECOME MORE AMPLIFIED ACROSS THE WRN CONUS
   THROUGH DAY 2. AHEAD OF THIS UPPER TROUGHING...A BROAD UPPER RIDGE
   WILL CONTINUE TO FLATTEN WHILE SLIDING EWD FROM THE PLAINS TOWARDS
   THE EAST COAST. STRONG MID LEVEL WSWLY FLOW OVER THE ROCKIES ON THE
   BACK SIDE OF THE UPPER RIDGE WILL AID IN STRENGTHENING THE LEE
   TROUGH OVER THE HIGH PLAINS. GIVEN THE PRESENCE OF A BROAD AREA OF
   SURFACE HIGH PRESSURE OVER THE SOUTHEAST STATES/GULF COAST
   REGION...AN INCREASE IN SLY WINDS WILL OCCUR OVER MUCH OF THE PLAINS
   STATES. IN ADDITION...STRONG MID LEVEL WINDS AND STEEP LAPSE RATES
   IN THE LOWER LEVELS WILL SUPPORT INCREASING SURFACE SWLY WINDS OVER
   THE SRN GREAT BASIN/DESERT SW AHEAD OF A COLD FRONT. ATTM...MIN RH
   READINGS IN BOTH OF THESE AREAS APPEAR TO BE SUFFICIENTLY HIGH THAT
   A CRITICAL FIRE WEATHER THREAT IS NOT APPARENT.
   
   ...SOUTHERN GREAT BASIN/DESERT SW...
   SWLY WINDS FROM 15-25 MPH WITH GUSTS OVER 30 MPH WILL BE POSSIBLE
   DURING THE PERIOD AS STRENGTHENING MID LEVEL WIND FIELDS OVERSPREAD
   THE REGION. THE STRONGEST WINDS ARE EXPECTED TO OCCUR OVER THE SRN
   GREAT BASIN...WHERE DEEPENING SURFACE LOW PRESSURE OVER NRN/CENTRAL
   NV WILL AID IN AN ADDITIONAL PRESSURE GRADIENT FORCE TO THE SURFACE
   WIND FIELDS. MIN RH READINGS OVER THE ENTIRE REGION ARE EXPECTED TO
   BE BORDERLINE CRITICAL /15-20 PERCENT/ AS WARM AIR REMAINS IN PLACE
   UNDER THE INFLUENCE OF SWLY WIND TRAJECTORIES. THE AREA WILL BE
   MONITORED FOR POSSIBLE LATER UPGRADE IF TRENDS INDICATE LOWER RH
   READINGS.
   
   ...SRN/CENTRAL PLAINS...
   SLY WINDS WILL INCREASE TO BETWEEN 15 AND 25 MPH /STRONGEST FROM THE
   TX PANHANDLE NEWD INTO CENTRAL KS ALONG LOW LEVEL JET AXIS/ AS THE
   LEE TROUGH/LOW LEVEL JET INTENSIFIES DURING THE PERIOD. MIN RH
   READINGS FROM 30-35 PERCENT OVER THE LOWER PLAINS OF OK AND KS...TO
   20-25 PERCENT OVER THE HIGH PLAINS...ARE EXPECTED DURING THE
   AFTERNOON HOURS. AGAIN THIS AREA WILL BE MONITORED FOR TREND IN
   POSSIBLE LOWER RH/CRITICAL CONDITIONS.
