   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0349 AM CDT THU SEP 18 2008
   
   VALID 191200Z - 201200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A SEASONABLY STRONG UPPER TROUGH WILL MOVE INTO THE GREAT BASIN
   TOMORROW. AHEAD OF THIS SYSTEM...A NARROW CORRIDOR OF MODEST SWLY
   WINDS WILL DEVELOP OVER PORTIONS OF THE SRN GREAT BASIN...LEADING TO
   NEAR CRITICAL FIRE WEATHER CONDITIONS. IN ADDITION...ISOLATED DRY
   TSTMS WILL BE POSSIBLE DURING THE AFTERNOON OVER PORTIONS OF THE
   NRN/ERN GREAT BASIN. HOWEVER...GIVEN THE EXPECTED MAJORITY OF WET
   TSTMS A CRITICAL FIRE WEATHER THREAT IS NOT EXPECTED. ELSEWHERE
   ACROSS THE NATION...A LARGE AREA OF SFC HIGH PRESSURE WILL CONTINUE
   TO BE LOCATED OVER THE ERN HALF OF THE NATION SUPPORTING LIGHT WINDS
   AND NO CRITICAL FIRE WEATHER CONDITIONS.
   
   ...SRN/WRN GREAT BASIN...
   A SEASONABLY STRONG UPPER TROUGH WILL MOVE EWD THROUGH NRN CA/SRN
   ORE AND INTO THE GREAT BASIN TOMORROW. AHEAD OF THIS SYSTEM...AN
   AREA OF SFC LOW PRESSURE WILL DEEPEN OVER THE NRN GREAT BASIN. AS A
   RESULT...SWLY SFC WINDS WILL INCREASE OVER SRN/CENTRAL NV AND
   PORTIONS OF ECENTRAL CA. THE COMBINATION OF THESE WINDS WITH
   SEASONABLY LOW RH READINGS /AROUND 15 PERCENT/ WILL PRODUCE NEAR
   CRITICAL FIRE WEATHER CONDITIONS.
   
   ...NRN/ERN GREAT BASIN...
   AHEAD OF AN UPPER SYSTEM...STRONG FORCING WILL OVERSPREAD THE REGION
   TOMORROW. AHEAD OF A COLD FRONT...INCREASING INSTABILITY WILL LEAD
   TO THE DEVELOPMENT OF SCT TSTMS. PWAT VALUES AROUND 0.75
   INCHES/RELATIVELY HIGH CLOUD BASES WILL SUPPORT INITIALLY DRY TSTMS.
   HOWEVER...DEGREE OF FORCING AND MID LEVEL MOISTENING WILL LEAD TO A
   TRANSITION TO MAINLY WET TSTMS OVERNIGHT.
