   NWS STORM PREDICTION CENTER NORMAN OK
   0415 AM CDT SUN AUG 06 2006
   
   VALID 061200Z - 071200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   JUST NORTH OF THE U.S./CANADIAN BORDER...STRONG SHORTWAVE TROUGH
   WILL PROGRESS FROM WESTERN ONTARIO INTO QUEBEC TONIGHT. IN ITS
   WAKE...UPPER RIDGE WILL GRADUALLY EXPAND WEST/NORTHWEST ACROSS THE
   MIDDLE OF THE CONUS. PERSISTENT CUT-OFF LOW OFF OF CA WILL NEAR THE
   NORTHERN CA COAST BY EARLY MONDAY MORNING.
   
   ...MUCH OF NV...
   AS THE UPPER LOW PROGRESSES TOWARD THE CA COAST...A MODEST INCREASE
   IN SOUTHERLY FLOW AHEAD OF THIS FEATURE WILL YIELD SLIGHTLY WARMER
   TEMPERATURES/HIGHER WIND SPEEDS ACROSS MUCH OF THE GREAT BASIN
   TODAY. BROAD SCALE SOUTH WINDS WILL LIKELY BE 10-20 MPH...WITH SOME
   HIGHER GUSTS.
   
   ...MUCH OF ORE/NORTHERN CA AND EXTREME WESTERN/NORTHERN NV...
   DOWNSTREAM OF THE UPPER LOW...ISOLATED-SCATTERED THUNDERSTORMS ARE
   EXPECTED LATE THIS AFTERNOON/TONIGHT ACROSS NORTHERN CA AND
   ALONG/EAST OF THE ORE CASCADES. MUCH OF THESE THUNDERSTORMS WILL BE
   DRY IN NATURE GIVEN THE EXISTENCE OF DRY SUB-CLOUD LAYERS. THE
   POTENTIAL WILL EXIST FOR NEW FIRE START VIA LIGHTNING STRIKES...IN
   ADDITION TO LOCALLY GUSTY/ERRATIC WINDS FROM THUNDERSTORM OUTFLOWS.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0418 AM CDT SUN AUG 06 2006
   
   VALID 071200Z - 081200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR MUCH OF NV/SOUTHEAST ORE/FAR
   SOUTHWEST ID...
   ...CRITICAL FIRE WEATHER AREA FOR EASTERN ORE/FAR SOUTHEAST
   WA/NORTHERN AND CENTRAL ID/FAR WESTERN MT FOR DRY THUNDERSTORMS...
   
   ...SYNOPSIS...
   HOT UPPER RIDGE WILL REMAIN THE PREVALENT FEATURE ACROSS A LARGE
   PORTION OF THE LOWER 48...ESPECIALLY THE NATIONS MID SECTION AND
   SOUTHEAST STATES. MAIN BELT OF MODERATE/STRONG WESTERLIES WILL BE
   CONFINED TO THE PACIFIC NORTHWEST AND FAR NORTHERN TIER INTO THE
   NORTHEAST STATES. BECOMING EMBEDDED WITHIN THIS FLOW REGIME...UPPER
   LOW WILL PROGRESS FROM THE NORTHERN CA COAST INTO ORE DURING THE
   PERIOD.
   
   ...CRITICAL FIRE WEATHER AREA - MUCH OF NV/SOUTHEAST ORE/FAR
   SOUTHWEST ID...
   
   PRIMARY CONDITIONS: GUSTY SOUTH WINDS AND LOW RH
   
   AS UPPER LOW/SHORTWAVE TROUGH SHIFTS NORTHEAST ACROSS NORTHERN
   CA...A DOWNSTREAM INCREASE IN WIND SPEEDS/PRESSURE GRADIENT WILL
   LEAD TO A HEIGHTENED FIRE DANGER ACROSS MUCH OF THE GREAT BASIN INTO
   SOUTHEAST ORE/SOUTHERN ID ON MONDAY. SUSTAINED WIND SPEEDS OF 20-25
   MPH APPEAR LIKELY...WITH HIGHER GUSTS. THE INCREASED SOUTHERLY
   GRADIENT WILL PROMOTE WARM TEMPERATURES ACROSS THE REGION...WITH
   MINIMUM RH VALUES OF 10-15 PERCENT.
   
   ...CRITICAL FIRE WEATHER AREA - EASTERN ORE/FAR SOUTHEAST
   WA/NORTHERN AND CENTRAL ID/FAR WESTERN MT FOR DRY THUNDERSTORMS...
   
   PRIMARY CONDITIONS: DRY THUNDERSTORMS AND LOCALLY GUSTY WINDS
   
   SCATTERED DRY THUNDERSTORMS WILL BE POSSIBLE ACROSS EASTERN ORE/FAR
   SOUTHEAST WA AND PORTIONS OF NORTHERN/CENTRAL ID INTO FAR WESTERN MT
   ON MONDAY. WITH SUFFICIENT INSTABILITY/FORCING FOR ASCENT VIA
   APPROACHING SHORTWAVE TROUGH...DRY SUB-CLOUD LAYERS /WITH MEAGER
   PROSPECTS FOR APPRECIABLE PRECIPITATION/ AND SUFFICIENTLY FAST STORM
   MOTIONS SHOULD SUPPORT MAINLY DRY THUNDERSTORMS. IN ADDITION TO
   POTENTIAL FOR LIGHTNING IGNITED FIRES...GUSTY/ERRATIC THUNDERSTORM
   DOWNDRAFT WINDS MAY ADVERSELY IMPACT FIRE CONTROL EFFORTS.
   
   ...NORTHERN PLAINS...
   AS SURFACE HIGH SHIFTS EASTWARD TOWARD THE UPPER MIDWEST ON
   MONDAY...INCREASING SOUTHERLY PRESSURE GRADIENT WILL YIELD
   MODERATELY GUSTY WINDS ACROSS A LARGE PORTION OF THE NORTHERN
   PLAINS. SUSTAINED SOUTH/SOUTHEAST WINDS WILL LIKELY REACH 15-20 MPH
   /WITH HIGHER GUSTS/...ESPECIALLY IN A CORRIDOR FROM NORTHERN NEB
   INTO SOUTH CENTRAL ND. IN SPITE OF THE GUSTY WINDS...TEMPERATURES
   WILL BE AROUND SEASONAL NORMS -- UPPER 80S/LOWER 90S -- IN THE WAKE
   OF THIS WEEKENDS COLD FRONT...WITH SUFFICIENTLY HIGH AFTERNOON
