   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0342 AM CDT SAT SEP 02 2006
   
   VALID 021200Z - 031200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER-LEVEL LOW ACROSS THE NRN PLAINS WILL ROTATE VERY SLOWLY
   SEWD...BLOCKED BY THE REMNANTS OF ERNESTO IN THE MID-ATLANTIC/ERN
   GREAT LAKES. LARGE UPPER-LEVEL RIDGE WILL REMAIN IN PLACE ACROSS THE
   NRN ROCKIES...PROVIDING WARM/DRY CONDITIONS BUT LIGHT WINDS. A WEAK
   UPPER-LEVEL TROUGH WILL LIFT NEWD TOWARDS THE NRN CA/SRN OR COAST
   TODAY...POSSIBLY PRODUCING A FEW DRY TSTMS ACROSS PORTIONS OF THE
   CASCADES. A MOIST AIR MASS AND WEAK MID-LEVEL IMPULSES WILL HELP
   GENERATE WIDESPREAD TSTM ACTIVITY ACROSS THE SRN ROCKIES. ALONG THE
   PERIPHERY OF THIS ACTIVITY...ISOLATED DRY TSTMS SHOULD OCCUR IN
   PORTIONS OF THE ERN GREAT BASIN.
   
   ...CASCADE RANGE IN SRN OR...
   A CONDITIONAL THREAT FOR DRY TSTMS EXISTS LATE THIS AFTERNOON AS A
   WEAK MID/UPPER-LEVEL TROUGH APPROACHES FROM OFFSHORE. MEAGER
   LOW/MID-LEVEL MOISTURE WILL RESULT IN LIMITED INSTABILITY ACROSS THE
   AREA. THE WEAK LIFT ASSOCIATED WITH THE TROUGH MAY BE SUFFICIENT TO
   WEAKEN THE CAP TO ALLOW ISOLATED DRY TSTMS TO DEVELOP. 
   
   ...SWRN UT/E-CNTRL NV...
   ISOLATED DRY TSTMS SHOULD OCCUR THIS AFTERNOON AS MID-LEVEL MOISTURE
   REMAINS TRAPPED BENEATH AN UPPER-LEVEL RIDGE. A RELATIVELY DRY
   LOW-LEVEL AIR MASS EXISTS THIS MORNING...AND A DEEPLY MIXED BOUNDARY
   LAYER WILL DEVELOP THIS AFTERNOON. LIMITED INSTABILITY AND FLOW
   ALOFT WILL RESULT IN ISOLATED COVERAGE OF ANY TSTMS THAT DO DEVELOP.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0421 AM CDT SAT SEP 02 2006
   
   VALID 031200Z - 041200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   VERY LITTLE CHANGE IN THE MID/UPPER-LEVEL PATTERN FROM DAY 1 IS
   EXPECTED ACROSS THE WRN/CNTRL CONUS. AN UPPER-LEVEL LOW WILL DRIFT
   SLOWLY EWD ACROSS THE UPPER MS RIVER VALLEY. LARGE UPPER-LEVEL RIDGE
   WILL REMAIN ENTRENCHED ACROSS THE NRN ROCKIES. A WEAK MID-LEVEL
   TROUGH SHOULD MOVE SLOWLY N/NEWD ACROSS THE NRN CA/SRN ORE COASTAL
   RANGE. MID-LEVEL MOISTURE SHOULD SLOWLY INCREASE ACROSS THE ERN
   GREAT BASIN UNDER WEAK SLY FLOW. WIND SPEEDS SHOULD REMAIN LIGHT IN
   WARM/DRY REGIONS OF THE NW/NRN ROCKIES. ISOLATED DRY TSTMS MAY OCCUR
   IN PORTIONS OF SRN ORE AND ERN GREAT BASIN.
   
   ...ERN NV/FAR WRN UT...
   MID-LEVEL MOISTURE IS FORECAST TO SLOWLY INCREASE FROM THE
   SOUTH...THUS CONTINUING AN ISOLATED DRY TSTM THREAT ACROSS THE
   REGION. THE LOW-LEVEL AIR MASS SHOULD REMAIN QUITE DRY...WITH TOTAL
   COLUMN PRECIPITABLE WATER VALUES NEARING A HALF-INCH. MODEL FORECAST
   SOUNDINGS INDICATE STEEP LOW-LEVEL LAPSE RATES DEVELOPING SUNDAY
   AFTERNOON WITH INVERTED-V TYPE THERMODYNAMIC STRUCTURE. RELATIVELY
   WARM TEMPERATURES IN THE UPPER-LEVELS WILL LIMIT AVAILABLE
   INSTABILITY AND SHOULD SUPPRESS MOST CONVECTION FROM DEVELOPING.
   
   ...CASCADE MTNS IN ORE...
   A CONDITIONAL THREAT FOR DRY TSTMS SHOULD ONCE AGAIN OCCUR SUNDAY
   AFTERNOON...AHEAD OF A WEAK AND SLOW MOVING MID-LEVEL TROUGH. WARM
   TEMPERATURES AND MARGINAL MOISTURE ALOFT WILL LIMIT INSTABILITY AND
   MAY SUFFICIENTLY CAP THE REGION FROM ANY CONVECTIVE DEVELOPMENT. IF
   TSTMS DO OCCUR...THEY WOULD LIKELY BE DRY GIVEN THE LARGE DEW-POINT
   DEPRESSIONS AT THE SURFACE.
