   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0142 AM CDT TUE AUG 12 2008
   
   VALID 121200Z - 131200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   LARGE SCALE PATTERN WILL REMAIN VERY SIMILAR...WITH THE UPPER TROUGH
   DOMINATING THE EAST...AND UPPER RIDGING DOMINATING MUCH OF THE WEST.
   UPPER RIDGING WILL SLOWLY STRENGTHEN OVER THE SOUTHWESTERN
   STATES...AND IN COMPARISON TO YESTERDAY...TEMPERATURES WILL BE A FEW
   DEGREES WARMER AT THE SURFACE IN RESPONSE.
     
   IN WA/OR/FAR NRN CA...A SHORT WAVE APPROACHING THE COAST WILL
   INCREASE SWLY WINDS. ISOLATED DRY THUNDERSTORMS MAY ALSO BE
   POSSIBLE...MAINLY NEAR THE CASCADES AND THE SISKIYOUS.
   
   ...WA/OR/FAR NRN CA...
   UPPER RIDGING OVER THE PACIFIC NW IS BEGINNING TO SHIFT EWD THIS
   MORNING AHEAD OF A WEAK SHORT WAVE TROUGH OF LOW PRESSURE THAT IS
   BEGINNING TO MOVE INTO THE BRITISH COLUMBIA COAST. RELATIVE
   HUMIDITIES WILL BE SOMEWHAT MARGINAL...WITH LOW TO MID 20S IN THE
   LOWER ELEVATIONS OF THE LEE OF THE CASCADES...AND UPPER TEENS TO
   LOWER 20S AT LOWER ELEVATIONS IN FAR NRN CA. DESPITE THIS...THERE
   MAY BE A SMALL AREA ON THE LEE OF THE CASCADES AND AT HIGHER
   ELEVATIONS THAT WILL EXPERIENCE SUSTAINED WINDS NEAR 20 MPH WITH
   STRONGER GUSTS. 
   
   IN FAR NRN CA...CNTRL OR...AND S/CNTRL WA...THERE IS CONSIDERABLE
   UNCERTAINTY AS TO WHETHER DRY THUNDERSTORMS WILL FORM LATER TODAY.
   MID LEVEL MOISTURE OBSERVED ROTATING AROUND THE BASE OF THE TROUGH
   WILL REACH WA/OR/NRN CA AT FAVORABLE HEATING...AND MAY BE SUFFICIENT
   TO GENERATE ISOLD THUNDERSTORMS...INITIALLY OVER HIGHER TERRAIN.
   ATTM...FORECAST SOUNDINGS INDICATE MINIMAL INSTABILITY...WHILE
   ENSEMBLE FORECASTS ARE ON THE LOWER END OF THIS PROBABILITY AS WELL.
   IF THUNDERSTORMS ARE ABLE TO FORM...LIGHTNING STRIKES AND
   GUSTY/ERRATIC WINDS WILL BE POSSIBLE AS STORMS MOVE OFF THE HIGHER
   TERRAIN.

   DAY 2 FIRE WEATHER OUTLOOK RESENT 1
   NWS STORM PREDICTION CENTER NORMAN OK
   0503 AM CDT TUE AUG 12 2008
   
   VALID 131200Z - 141200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   THE UPPER LOW WILL CONTINUE TO REMAIN NEARLY STATIONARY OVER
   QUEBEC...WITH UPPER TROUGHING DOMINATING THE EAST...AND VERY HEAVY
   RAINFALL IN MUCH OF THE SOUTHEAST/MID ATLANTIC. ACROSS THE CENTRAL
   STATES...GUSTY SLY WINDS WILL AFFECT MUCH OF THE SRN/CNTRL
   PLAINS...ALTHOUGH RELATIVE HUMIDITIES ARE EXPECTED TO STAY ABOVE
   CRITICAL THRESHOLDS.
   
   MEANWHILE IN THE WEST...THE UPPER RIDGE WILL CONTINUE TO
   AMPLIFY...LEADING TO ABOVE NORMAL TEMPERATURES AT THE SURFACE IN
   RESPONSE. A WIDESPREAD AREA OF RELATIVE HUMIDITIES IN THE SINGLE
   DIGITS TO THE TEENS WILL BE COMMON. DESPITE THIS...WINDS ARE
   EXPECTED TO REMAIN LIGHT.
