   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0311 AM CDT SUN JUL 12 2009
   
   VALID 121200Z - 131200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR FAR NRN CA...SWRN/CNTRL/ERN ORE...
   ...CRITICAL FIRE WEATHER AREA FOR MUCH OF NV...FAR NERN CA...S CNTRL
   ORE...
   ...CRITICAL FIRE WEATHER AREA FOR SRN HIGH PLAINS...
   
   ...SYNOPSIS...
   A STRONG SHORT WAVE TROUGH AND ATTENDANT SURFACE COLD FRONT WILL
   BEGIN TO SHIFT EWD INTO THE PACIFIC NORTHWEST/GREAT BASIN. DRY
   THUNDERSTORMS WILL LIKELY AFFECT PORTIONS OF FAR NRN CA AND MUCH OF
   ORE IN ASSOCIATION WITH THE SYSTEM...WHILE SOUTH OF THIS STRONG AND
   GUSTY WINDS WILL ALIGN WITH LOW RH FOR CRITICAL CONDITIONS OVER MUCH
   OF NV.
   
   FARTHER E...AN UPPER HIGH WILL REMAIN OVER THE SRN PLAINS...WITH HOT
   TEMPERATURES AT THE SURFACE. A QUASI-STATIONARY FRONT WILL STRETCH
   THROUGH THE CNTRL PLAINS INTO THE LOWER OH VALLEY THEN INTO THE TN
   VALLEY AND THE CAROLINAS. STRONG/GUSTY WINDS WILL ALIGN WITH LOW RH
   SOUTH OF THIS ACROSS PORTIONS OF THE SRN HIGH PLAINS.
   
   ...CRITICAL FIRE WEATHER AREA - FAR NRN CA...SWRN/CNTRL/ERN ORE...
   
   PRIMARY CONDITIONS: DRY THUNDER
   
   EARLY MORNING WV IMAGERY SHOWS A PLUME OF GREATER MOISTURE FROM THE
   REMNANTS OF T.S. BLANCA STREAMING NEWD THROUGH CNTRL/NRN CA AND WRN
   NV...NWD INTO CNTRL ORE...THEN NEWD TOWARDS THE ID PANHANDLE. ISOLD
   DRY THUNDERSTORMS HAVE BEEN NOTED ALONG THIS AXIS OF MOISTURE THIS
   MORNING. MEANWHILE...LONG LOOP OF WV IMAGERY SHOWS TWO NOTABLE
   DISTURBANCES ROTATING AROUND A STRONG SHORT WAVE TROUGH NOW OFF THE
   OREGON COAST. ONE NEARLY DUE S OF THE MAIN LOW OFFSHORE OF CA WILL
   LIKELY INFLUENCE ISOLD CONVECTION THIS MORNING ALONG COASTAL AREAS
   OF NRN CA AND ORE. A SECOND MORE FAVORABLY TIMED DISTURBANCE TO THE
   W OF THE MAIN LOW WILL TRIGGER DRY THUNDERSTORMS BY AFTERNOON. AS
   THE UPPER LOW PROGRESSES INLAND...MOISTURE STREAMING NEWD/NWD FROM
   T.S. BLANCA WILL SHIFT EWD AS WELL...ALLOWING A DRY SLOT TO SHIFT
   INTO NRN CA AND CNTRL/ERN ORE. AMPLE SURFACE HEATING WILL
   EFFECTIVELY DESTABILIZE THE ATMOSPHERE BEFORE THE AFOREMENTIONED
   FAVORABLY TIMED DISTURBANCE MOVES INTO THE ORE/CA COAST. DRY
   THUNDERSTORMS WILL ESPECIALLY BE FAVORED IN THE 21-03Z TIME
   FRAME...AND ALTHOUGH COVERAGE WILL GRADUALLY DECREASE...STORMS MAY
   PERSIST THROUGH 12Z. GUSTY AND ERRATIC WINDS CAN BE ANTICIPATED WITH
   ANY THUNDERSTORMS THAT OCCUR. ADDITIONALLY...SUSTAINED 15 TO 20 MPH
   WINDS WITH HIGHER GUSTS WILL ALIGN WITH RHS IN THE TEENS AND 20S.
   
   ...CRITICAL FIRE WEATHER AREA - MUCH OF NV...FAR NERN CA...S CNTRL
   ORE...
   
   PRIMARY CONDITIONS: STRONG WINDS/LOW RH/DROUGHT/ANTECEDENT DRYNESS
   
   AS A COLD FRONT PROGRESSES THROUGH THE PACIFIC NORTHWEST/GREAT BASIN
   AND SURFACE HIGH PRESSURE QUICKLY BUILDS IN BEHIND...STRONG WINDS
   WILL AFFECT A WIDESPREAD AREA ACROSS NV/FAR NERN CA AND S CNTRL ORE.
   DESPITE MID TO UPPER LEVEL CLOUDS THAT WILL OVERSPREAD MUCH OF NV
   LIMITING STRONGER HEATING...TEMPERATURES WILL STILL WARM INTO THE
   90S IN NRN/CNTRL NV TO NEAR 105 F IN SRN NV...WHILE TEMPERATURES IN
   THE UPPER 70S/LOWER 80S CAN BE ANTICIPATED IN NERN CA AND S CNTRL
   ORE. RHS WILL WIDELY FALL INTO THE TEENS. AS TEMPERATURES WARM
   DURING THE AFTERNOON...DRY LOW LEVELS/STEEP LOW LEVEL LAPSE RATES
   WILL ALLOW STRONGER JET MAX WINDS TO MIX AT THE SURFACE...WITH
   SUSTAINED SPEEDS NEAR 20 TO 25 MPH AND GUSTS UP TO 40 MPH. ISOLD DRY
   THUNDERSTORMS MAY BE POSSIBLE AS A PLUME OF GREATER MOISTURE IN
   ASSOCIATION WITH T.S. BLANCA SHIFTS EWD AHEAD OF THE UPPER LOW.
   
   ...CRITICAL FIRE WEATHER AREA - SRN HIGH PLAINS...
   
   PRIMARY CONDITIONS: STRONG WINDS/LOW RH/VERY HOT TEMPERATURES
   
   GUSTY SLY WINDS WILL DEVELOP ONCE AGAIN S OF A QUASI-STATIONARY
   FRONT STRETCHING THROUGH MUCH OF KS. SUSTAINED SPEEDS NEAR 20 TO 25
   MPH WITH GUSTS TO 35 MPH CAN BE ANTICIPATED. TEMPERATURES WILL
   QUICKLY WARM INTO THE UPPER 90S TO NEAR 108 F...WITH RHS WIDELY IN
   THE TEENS.
   
   ...NERN NV/SWRN ID/NWRN UT...
   WV IMAGERY SHOWS GREATER MOISTURE AROUND THE PERIPHERY OF THE SRN
   PLAINS UPPER HIGH IS SHIFTING EWD...WITH DRIER AIR TEMPORARILY
   MOVING INTO THE AREA. ISOLD DRY THUNDERSTORMS MAY BE POSSIBLE BEFORE
   MOISTURE BEGINS TO INCREASE FROM THE W BY LATE AFTERNOON/EVENING.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0346 AM CDT SUN JUL 12 2009
   
   VALID 131200Z - 141200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A STRONG SHORT WAVE TROUGH AND ATTENDANT SURFACE COLD FRONT WILL
   CONTINUE TO PROGRESS ACROSS THE NWRN STATES TOWARDS THE NRN PLAINS.
   BREEZY CONDITIONS WILL LIKELY ALIGN WITH MARGINAL RHS ACROSS MUCH OF
   WY/NERN UT AND ERN ID. 
   
   MEANWHILE HIGH PRESSURE WILL LINGER OVER THE SRN PLAINS...WITH HOT
   AND DRY CONDITIONS AFFECTING A LARGE AREA FROM THE SRN PLAINS WWD
   INTO THE SWRN STATES. STRONG/GUSTY SLY WINDS CAN BE ANTICIPATED S OF
   A QUASI-STATIONARY FRONT IN THE SRN HIGH PLAINS ONCE AGAIN...THOUGH
   WITH MARGINAL RHS.
   
   ...WY...
   STRONG POST-FRONTAL WLY WINDS NEAR 25 TO 30 MPH WILL AFFECT MUCH OF
   WY BY THE AFTERNOON. AS TEMPERATURES WARM INTO TO THE UPPER 70S TO
   MID 80S AND LOW LEVEL LAPSE RATES CONTINUE TO STEEPEN...STRONGER
   GUSTS UP TO 40 MPH CAN BE EXPECTED AS STRONGER JET WINDS MIX TO THE
   SURFACE. MARGINAL RHS AND ABOVE NORMAL 100/1000 HR FUEL MOISTURE MAY
   TEMPER THE OVERALL THREAT.
   
   ...SRN HIGH PLAINS...
   SIMILAR TO THE PAST FEW DAYS...VERY HOT TEMPERATURES WILL BE LIKELY
   BY AFTERNOON...WITH HIGHS GENERALLY A0A 100 F. STRONG/GUSTY SLY
   WINDS WILL ONCE AGAIN DEVELOP S OF A QUASI-STATIONARY FRONT
   STRETCHED ACROSS THE CNTRL PLAINS...THOUGH MARGINAL RHS MAY TEMPER
   THE OVERALL THREAT. HOWEVER...SHOULD LOWER RHS BE FORECAST
   TOMORROW...A CRITICAL WILL NEED TO BE OUTLINED.
