   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0349 AM CDT SAT JUL 22 2006
   
   VALID 221200Z - 231200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A STRONG UPPER RIDGE WILL REMAIN OVER THE WRN STATES THROUGH TODAY.
   NEAR RECORD TEMPERATURES WILL EXIST IN MOST OF THE WEST AS A RESULT.
   MEANWHILE UPPER TROUGHING WILL DEEPEN OVER THE ERN CONUS. AN
   ASSOCIATED COLD FRONT WILL PUSH SEWD EXTENDING FROM SRN TX INTO THE
   MID ATLANTIC BY THIS EVENING. IN THE WAKE OF THE FRONT NLY WINDS
   WILL BE PREVALENT ACROSS MOST OF THE MIDWEST/PLAINS. THE STRONGEST
   NLY WINDS WILL OCCUR OVER THE SRN PLAINS...WHERE LOW RH READINGS
   WILL ALSO EXIST LEADING TO HIGH FIRE DANGER. WRAPPING AROUND THE
   UPPER RIDGE MID LEVEL MOISTURE WILL SUPPORT ISOLATED TSTMS /MAINLY
   DRY/ OVER PORTIONS OF THE INTERIOR PAC NW. COVERAGE SHOULD REMAIN
   SUB-CRITICAL HOWEVER.
   
   ...SRN OK/NRN TX...
   BREEZY NLY WINDS WERE OCCURRING EARLY THIS MORNING OVER MUCH OF
   SRN/CENTRAL OK IN THE WAKE OF A COLD FRONT. SCT PRECIPITATION
   OCCURRED YESTERDAY EVENING OVER SRN OK...BUT GENERALLY THE RAINFALL
   AMTS WERE NOT ENOUGH TO ALLEVIATE THE VERY DRY CONDITIONS. A 30 KT
   NLY 850 JET WILL MOVE SWD THROUGH OK THIS MORNING AND INTO NRN TX
   THIS AFTERNOON. ALONG WITH A DEEPLY MIXED ENVIRONMENT...SUSTAINED
   NLY WINDS FROM 15-20 MPH ARE ANTICIPATED OVER SRN OK/NRN TX THIS
   AFTERNOON. DEEP MIXING WILL SUPPORT TEMPERATURES AROUND 90 AND
   DEWPTS IN THE 50S SUPPORTING MIN RH READINGS FROM 20-25 PERCENT AND
   AN ENHANCED FIRE DANGER.
   
   ...INTERIOR PAC NW...
   MID LEVEL MOISTURE WELL SAMPLED BY THE 00Z RENO AND MEDFORD
   SOUNDINGS WILL CONTINUE TO MOVE NWD INTO ORE AND WA DURING THE
   PERIOD. WITH LACK OF ANY ORGANIZED MID LEVEL FORCING...TERRAIN WILL
   REMAIN THE MAIN INITIATION MECHANISM. GIVEN THE AMT OF MID LEVEL
   MOISTURE /PWAT VALUES AROUND 1 INCH/ AND LACK OF WLY COMPONENT TO
   THE MID LEVEL WIND FIELDS...MOST CONVECTION WILL BE A MIX OF WET/DRY
   ALONG THE HIGHER TERRAIN OF THE CASCADE MTNS. THE MOST LIKELY DRY
   TSTM POTENTIAL JUST IMMEDIATELY EAST OF THE MTNS IN THE HIGH
   DESERT/COLUMBIA RIVER BASIN OF ERN ORE/SCENTRAL WA. HOWEVER TSTM
   COVERAGE IN THIS AREA IS ANTICIPATED TO REMAIN ISOLATED PRECLUDING A
   CRITICAL DRY TSTM THREAT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0350 AM CDT SAT JUL 22 2006
   
   VALID 231200Z - 241200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR DRY TSTMS OVER THE INTERIOR  PAC
   NW...
   
   ...SYNOPSIS...
   THE UPPER RIDGE OVER THE WEST WILL BEGIN TO BREAKDOWN DURING THE DAY
   TWO PERIOD OVER THE PAC NW IN RESPONSE TO SEVERAL APPROACHING UPPER
   TROUGHS. THESE TROUGHS WILL INTERACT WITH MID LEVEL MOISTURE AND HOT
   SFC TEMPERATURES TO SUPPORT SCT DRY TSTMS OVER THE INTERIOR PAC NW.
   ELSEWHERE ACROSS THE WEST...WELL ABOVE NORMAL TEMPERATURES WILL
   OCCUR UNDER THE PRESENCE OF THE UPPER RIDGE. LOW RH READINGS WILL
   RESULT...BUT GENERALLY LIGHT WINDS WILL LIMIT ANY ADDITIONAL
   CRITICAL FIRE WEATHER THREATS IN THE WEST. ELSEWHERE ACROSS THE
   NATION...LOW RH READINGS WILL AGAIN BE PRESENT OVER THE CENTRAL/SRN
   PLAINS...BUT WINDS WILL BE LIGHT. ACROSS THE NRN PLAINS...ANOTHER
   WEAK COLD FRONT WILL MOVE SWD THROUGH THE REGION. IN THE WAKE OF THE
   FRONT...NLY WINDS WILL REDEVELOP.
   
   ...CRITICAL FIRE WEATHER AREA - MUCH OF INTERIOR WA/ORE EAST OF THE
   CASCADE MTNS...WRN ID...
   
   PRIMARY CONDITIONS: SCT DRY TSTMS
   
   SEVERAL WEAK SHORTWAVE TROUGHS SEVERAL HUNDRED MILES OFF THE NRN
   CA/ORE AND WA COAST EARLY THIS MORNING WILL MOVE TOWARDS/INTO THE
   PAC NW ON SUNDAY. MID LEVEL MOISTURE THAT WILL RESIDE ALONG THE
   CASCADE MTNS TODAY WILL BE LIFTED ENEWD INTO ERN ORE/WA AND WRN ID
   DURING THE PERIOD AHEAD OF THE APPROACHING TROUGH/S. AT LOW
   LEVELS...HOT TEMPERATURES WITH READINGS FROM 95-105 DEG F WILL EXIST
   AND SUPPORT A DEEPLY MIXED BNDRY LAYER UP TO 12 KFT AGL ALONG WITH
   SUPPORTING TSTM DEVELOPMENT. DESPITE RELATIVELY HIGH PWAT VALUES
   FORECASTED /FROM 0.80 TO 1 INCH/ INCREASING MID LEVEL WIND FIELDS
   WILL SUPPORT MODEST MOVEMENT OF TSTMS AND LITTLE TIME FOR TSTMS TO
   REMAIN IN ONE LOCATION AND TRANSITION TO WET.
   
   ...NRN PLAINS...
   IN THE WAKE OF A WEAK COLD FRONT...WINDS WILL INCREASE OUT OF THE
   NORTH TO BETWEEN 10-20 MPH. TEMPERATURES WILL COOL LITTLE WITH
   AFTERNOON READINGS IN THE 90S. SLIGHTLY LOWER DEWPTS IN THE WAKE OF
   THE FRONT WILL SUPPORT MIN RH READINGS FROM 15-20 PERCENT. LACK OF
   STRONGER WINDS WILL PRECLUDE ANY CRITICAL FIRE WEATHER CONCERNS.
