   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0352 AM CDT SUN JUL 23 2006
   
   VALID 231200Z - 241200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A STRONG UPPER RIDGE WILL REMAIN IN PLACE OVER THE WEST THROUGH THE
   PERIOD WITH WELL ABOVE NORMAL TEMPERATURES CONTINUING OVER MUCH OF
   THE REGION. MONSOONAL MOISTURE WILL CONTINUE TO ROTATE AROUND THE
   RIDGE AND AID IN SCT-NMRS TSTMS DURING THE AFTERNOON/EVENING.
   ALTHOUGH A FEW DRY TSTMS MAY BE POSSIBLE OVER THE NRN GREAT BASIN
   AND INTERIOR PAC NW...LACK OF A STRONGER FORCING MECHANISM AND
   INCREASING MID LEVEL MOISTURE WILL PRECLUDE A CRITICAL DRY TSTM
   EVENT. ACROSS THE REMAINDER OF THE NATION SFC HIGH PRESSURE WILL
   BUILD EWD INTO THE OHIO VALLEY. IN THE WAKE OF THE SFC HIGH AN UPPER
   TROUGH WILL MOVE SEWD OUT OF CANADA AND SUPPORT INCREASING WINDS
   OVER THE PLAINS REGION.
   
   ....ERN ORE/WRN AND SRN ID...
   WITH RELATIVELY WEAK TO NON-EXISTENT MID LEVEL HEIGHT FALLS...LITTLE
   TO NO MID LEVEL COOLING AND INCREASING MID LEVEL MOISTURE/PRECIP
   WATER...EXPECT CONVECTION OVER THE REGION TO INITIALLY START OUT DRY
   BUT TRANSITION RELATIVELY QUICKLY TO A MIX OF WET/DRY. WITHOUT A
   MORE FOCUSED AND SIGNIFICANT DRY TSTM EVENT EXPECTED HAVE DOWNGRADED
   THE CRITICAL OUTLOOK AREA.
   
   ...INTERIOR NRN/CENTRAL CA...
   ISOLATED TO SCT TSTMS ARE ANTICIPATED OVER THE COASTAL RANGES AND
   MOVE INTO THE IMMEDIATE FOOTHILLS/VALLEYS FROM CENTRAL INTO NRN CA
   TODAY AND TONIGHT. GIVEN VERY HOT TEMPERATURES /105-115 DEG F/ SOME
   OF THESE STORMS MAY BE INITIALLY DRY. GIVEN RELATIVELY MOIST MID
   LEVELS THE EXPECTED TRANSITION TO WET TSTMS WILL PRECLUDE A CRITICAL
   FIRE WEATHER THREAT.
   
   ...CENTRAL PLAINS...
   SLY WINDS WILL INCREASE TODAY AS PRESSURE FALLS COMMENCE IN THE WAKE
   OF A SFC HIGH PRESSURE AND AHEAD OF A SHORTWAVE TOPPING THE WRN
   RIDGE AND MOVING SEWD INTO MT/ND. WELL ABOVE NORMAL TEMPERATURES IN
   THE 90S ALONG WITH MIN RH READINGS AROUND 25 PERCENT WILL AID IN AN
   INCREASED FIRE DANGER. HOWEVER SUSTAINED SLY WINDS SHOULD REMAIN
   BELOW 20 MPH.
   
   ...MT...
   BEHIND A WEAK COLD FRONT AND NORTH OF A SFC LOW OVER WY...NLY WINDS
   FROM 10-20 MPH WILL DEVELOP. VERY WARM TEMPERATURES IN THE 90S TO
   LOWER 100S AND LOW DEWPTS WILL SUPPORT MIN RH READINGS FROM 15-20
   PERCENT. LACK OF STRONGER UPPER SYSTEM/SFC WINDS WILL PRECLUDE A
   CRITICAL FIRE WEATHER THREAT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0353 AM CDT SUN JUL 23 2006
   
   VALID 241200Z - 251200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   UPPER RIDGE OVER THE WEST WILL SLOWLY SHIFT SWD AS SEVERAL WEAK
   UPPER TROUGHS MOVE FROM THE NRN PACIFIC INTO THE NRN ROCKIES/SWRN
   CANADA. MID LEVEL MOISTURE WILL CONTINUE TO ROTATE AROUND THE UPPER
   RIDGE SUPPORTING SCT-NMRS TSTMS. A FEW TSTMS MAY BE DRY...GIVEN THE
   VERY WARM TEMPERATURES AT THE SFC OVER LOWER ELEVATIONS OF THE GREAT
   BASIN AND NRN ROCKIES...HOWEVER MOST TSTMS ARE ANTICIPATED TO
   TRANSITION TO WET WITH TIME. ELSEWHERE ACROSS THE NATION...SLY WINDS
   WILL INCREASE OVER THE CENTRAL/SRN PLAINS. ALONG WITH ABOVE NORMAL
   TEMPERATURES...THE LACK OF SIGNIFICANT MOISTURE RETURN WILL LEAD TO
   MIN RH READINGS FROM 20-25 PERCENT OVER THE HIGH PLAINS.
   
   ...ERN WA/NRN ID...
   AS THE UPPER RIDGE GETS SHUNTED SWD...INCREASING MID LEVEL FLOW WILL
   DEVELOP OVER THE AREA. IN ADDITION MID LEVEL COOLING WILL OCCUR
   HOWEVER LITTLE SENSIBLE COOLING WILL OCCUR IN THE LOW LEVELS.
   HOWEVER WITH RELATIVELY HIGH AMTS OF MID LEVEL MOISTURE...ANY TSTMS
   SHOULD TRANSITION TO WET WITH TIME. THUS ONLY ISOLATED DRY TSTMS ARE
   EXPECTED TO OCCUR AND THESE ARE ANTICIPATED TO OCCUR ON THE NRN
   FRINGES OF THE MID LEVEL MOISTURE/INSTABILITY  OVER ERN WA/NRN ID.
   IN ADDITION BREEZY WLY WINDS FROM 15-20 MPH ARE POSSIBLE THROUGH THE
   COLUMBIA RIVER GORGE AND WRN BASIN WITH THE AID OF AN INCREASING
   PRESSURE GRADIENT. 
   
   ...PORTIONS OF INTERIOR CA...
   WITH FALLING MID LEVEL HEIGHTS THE SFC THERMAL TROUGH SHOULD MOVE
   INTO THE CENTRAL VALLEY DURING THE PERIOD. AS A RESULT...THE SEA
   BREEZE WILL GATHER STRENGTH DURING THE DAY MONDAY. LITTLE SENSIBLE
   COOLING WILL BE FELT WELL INLAND...BUT AN INCREASING PRESSURE
   GRADIENT WILL AID IN SUSTAINED WINDS UP TO 20 MPH FOR A FEW HR
   PERIOD IN FAVORABLE LOCATIONS. THESE WINDS WILL COMBINE WITH MIN RH
   READINGS FROM 20-25 PERCENT DUE TO TEMPERATURES IN THE 95-105 RANGE
   TO ENHANCE THE FIRE DANGER.
   
   ...CENTRAL/SRN HIGH PLAINS...
   AN AREA OF LOW PRESSURE WILL DEEPEN OVER NEB/SD AS SEVERAL MID LEVEL
   IMPULSES MOVE EWD ATOP THE WRN UPPER RIDGE INTO THE NRN/CENTRAL
   PLAINS. THE RESULTANT STRENGTHENING SFC PRESSURE GRADIENT WILL
   SUPPORT SUSTAINED SLY WINDS FROM 15-20 MPH. LACK OF ANY MOISTURE
   RETURN AND WARMING TEMPERATURES INTO THE UPPER 90S WILL PRODUCE MIN
   RH READINGS FROM 20-25 PERCENT.
