   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   PERSISTENT UPPER-LEVEL RIDGE WILL REMAIN ANCHORED OVER THE LOWER MS
   RIVER VALLEY. A VIGOROUS SHORT WAVE TROUGH CENTERED OVER NRN/CNTRL
   CA WILL WEAKEN AS IT EJECTS TOWARDS THE NRN/CNTRL ROCKIES. AN
   UPSTREAM IMPULSE OFF THE PACIFIC NW COAST WILL AMPLIFY INTO THE
   PACIFIC NW/NRN CA BY EARLY SUN...EFFECTIVELY MAINTAINING A
   LARGE-SCALE TROUGH ACROSS THE WEST.
   
   ...MOJAVE DESERT OF SRN CA/FAR SRN NV...
   AS THE NRN/CNTRL CA SHORT WAVE TROUGH TRACKS NEWD TODAY...MODERATE
   TO STRONG W/SWLY LOW/MID-LEVEL FLOW WILL PROMOTE SUBSTANTIAL DRYING
   OFF THE SRN CA COASTAL RANGES AND ACROSS THE MOJAVE DESERT INTO FAR
   SRN NV. SUSTAINED WINDS OF 20 TO 25 MPH SHOULD BE JUXTAPOSED WITH RH
   VALUES FALLING TO BETWEEN 8 AND 15 PERCENT DURING THE LATE

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0353 AM CDT SAT JUN 20 2009
   
   VALID 211200Z - 221200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   UPPER-LEVEL PATTERN WILL CONTINUE TO BE CHARACTERIZED BY A RIDGE
   AXIS ACROSS THE MS RIVER VALLEY AND A TROUGH IN THE WEST. AN
   EMBEDDED SHORT WAVE TROUGH EXPECTED TO BE CENTERED ACROSS THE
   PACIFIC NW/NRN CA EARLY SUN SHOULD SLOWLY TRACK E/NEWD TOWARDS THE
   NRN ROCKIES. A BROAD BELT OF MODERATE TO STRONG MID-LEVEL W/SWLYS
   WILL PERSIST S OF THIS SHORT WAVE ACROSS FROM MUCH OF CA...TO THE
   CNTRL/SRN GREAT BASIN AND THE CNTRL ROCKIES.
   
   ...FAR SERN NV/SWRN UT/NWRN AZ...
   CONSENSUS OF MODEL GUIDANCE SUGGESTS SUSTAINED SURFACE WINDS OF 20
   TO 25 MPH WILL DEVELOP AT PEAK HEATING GIVEN 40 TO 50 MPH WINDS AT
   500 MB. ALTHOUGH TEMPERATURES ARE EXPECTED TO REMAIN SLIGHTLY BELOW
   NORMAL...SUBSTANTIAL DRYING OVER THE WRN/CNTRL MOJAVE DESERT ON
   SAT/DAY 1 SHOULD SPREAD E/NEWD. THIS SHOULD LEAD TO RH BECOMING 
   MARGINALLY LOW /AROUND 15 PERCENT/ AT MODERATE ELEVATION LOCALES.
   OVERALL SETUP SHOULD SUPPORT LOCALIZED CRITICAL CONDITIONS WHERE
   FUELS HAVE SUFFICIENTLY CURED INVOF NV/UT/AZ BORDER.
