   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0234 AM CDT MON JUN 29 2009
   
   VALID 291200Z - 301200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   THE POTENTIAL FOR LARGE SCALE AREAS WITH STRONG WINDS/CRITICALLY LOW
   RH WILL BE LOW TODAY.  A CLOSED UPPER LOW WILL REMAIN SITUATED OVER
   THE GREAT LAKES WITH A TROUGH IN THE NERN CONUS AND A MID-UPPER
   ANTICYCLONE WILL BE CENTERED NEAR THE MIDDLE COLORADO RIVER VALLEY. 
   A WEAK FRONTAL BOUNDARY WILL BE DRAPED FROM THE LOWER MISSOURI RIVER
   VALLEY NWWD TOWARDS THE NRN HIGH PLAINS THEN WSWWD TO THE NRN GREAT
   BASIN.  SOME MID-LEVEL MOISTURE AND LIFT ALONG THE BOUNDARY DEPICTED
   IN MODEL FORECAST SOUNDINGS WILL LEAD TO ISOLD TSTMS IN PARTS OF THE
   NRN ROCKIES...WITH ISOLD-SCTD TSTMS ELSEWHERE OVER THE CNTRL
   ROCKIES/DESERT SW AND SIERRAS.  THE LATEST MODEL GUIDANCE CONTINUES
   TO INDICATE THAT DRY TSTM POTENTIAL WILL REMAIN LOW/SPARSE OVER THE
   NRN GREAT BASIN/NRN ROCKIES AND PERHAPS THE SRN HALF OF THE SIERRAS.
    LOW MAGNITUDE OF THREAT PRECLUDES THE DELINEATION OF ANY CRITICAL
   AREAS.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0312 AM CDT MON JUN 29 2009
   
   VALID 301200Z - 011200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   LITTLE CHANGE OVERALL IN A SEEMINGLY BENIGN FIRE WEATHER PATTERN FOR
   THE LOWER 48 FROM D1 TO D2.  EXPANSIVE UPPER LOW WILL REMAIN FIXED
   OVER THE LOWER GREAT LAKES WITH A LARGE MID-UPPER ANTICYCLONE
   CENTERED OVER THE COLORADO RIVER VALLEY.  A WEAK SHORTWAVE TROUGH
   WILL INFLUENCE THE NRN ROCKIES WITH A COLD FRONT MOVING EWD OVER THE
   AREA INTO THE NRN HIGH PLAINS.  SOME ISOLD-SCTD TSTMS WILL LIKELY
   DEVELOP OVER THE N-CNTRL ROCKIES DURING THE AFTERNOON/EVENING.  THE
   DRY TSTM THREAT APPEARS SUFFICIENTLY LOW...ALONG WITH LIMITED FUEL
   RECEPTIVENESS ACCORDING TO THE LATEST GACC INFORMATION.  
   
   FURTHER W...LATEST GFS/ECMWF MODEL OUTPUT SHOW A WEAK MID-LEVEL
   PERTURBATION NEAR N-CNTRL CA TOWARDS 00Z/WED.  MID-LEVEL MOISTURE
   AND TERRAIN INDUCED CIRCULATIONS WILL COMBINE WITH WEAK UPPER ASCENT
   PROVIDED BY THE AFOREMENTIONED MID-LEVEL WEAKNESS--YIELDING ISOLD
   TSTMS OVER THE SIERRAS.
