   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0432 AM CDT TUE JUN 19 2007
   
   VALID 191200Z - 201200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   EARLY MORNING WATER VAPOR LOOPS SHOW NEXT STORM SYSTEM APPROACHING
   WRN BC. AS THIS OCCURS...MID LEVEL WINDS WILL INCREASE AND BECOME
   SWLY ACROSS THE NORTHWEST AND GREAT BASIN. THIS WILL HELP AMPLIFY
   THE RIDGE ACROSS THE SOUTHWEST AND SET THE STAGE FOR INCREASING SFC
   WINDS ACROSS THE GREAT BASIN BY MIDWEEK. FARTHER EAST...LONGWAVE
   UPPER TROUGH WILL MOVE EAST FROM THE MIDWEST INTO QUEBEC BY EARLY
   WED...WITH AN ELONGATED FRONTAL ZONE FROM WRN PA THROUGH THE TN
   VALLEY BY LATE AFTN. FIRE CONCERNS APPEAR TO BE MINIMAL ACROSS THE
   CONUS TODAY. THERE IS STILL A SLIGHT CHANCE FOR ISOLD DRY TSTMS
   ACROSS FAR SERN AZ/FAR WRN NM.
   
   ...SERN AZ/WRN NM...
   AS HIGH PRESSURE BEGINS TO BUILD AGAIN OVER THE REGION...MID LEVEL
   MOISTURE WILL BE ADVECTED NWD INTO SERN AZ DURING THE DAY. LARGE
   SCALE LIFT WILL BE LACKING. HOWEVER...SUFFICIENT INSTABILITY WILL BE
   AVAILABLE GIVEN STEEP LAPSE RATES AND ADEQUATE MID LEVEL MOISTURE.
   THERMODYNAMIC PROFILES SUPPORT MAINLY DRY TSTMS...AND THIS WILL
   PRESENT A SLIGHTLY GREATER THREAT ACROSS AZ GIVEN DRIER FUELS IN
   PLACE. COVERAGE IS EXPECTED TO BE MINIMAL.

   VALID 201200Z - 211200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR NERN NV/NRN UT/SERN ID/WRN WY/WRN
   CO...
   
   ...SYNOPSIS...
   RIDGE WILL CONTINUE TO BUILD ACROSS THE WEST ON WEDNESDAY...WITH A
   CONTINUED WARMING TREND AND INCREASED WINDS OVER THE GREAT BASIN.
   PRIMARY MID LEVEL JET STREAK WILL REMAIN OFFSHORE UNTIL LATE IN THE
   PERIOD. HOWEVER...SMALLER SCALE IMPULSES WILL MOVE ACROSS THE GREAT
   BASIN ON WEDNESDAY. MAIN SFC LOW PRESSURE WILL DEEPEN OVER MT...WITH
   A COLD FRONT FORECAST TO EXTEND SWWD INTO CNTRL ORE BY WEDNESDAY
   AFTN. CRITICAL FIRE CONDITIONS MAY BECOME POSSIBLE ACROSS PORTIONS
   OF THE GREAT BASIN AND CO/WY IN RESPONSE TO INCREASING WINDS/TEMPS
   ON WEDNESDAY.
   
   ...CRITICAL FIRE WEATHER AREA - NERN NV/NRN UT/SERN ID/WRN WY/WRN
   CO...
   
   PRIMARY CONDITIONS: SUSTAINED WINDS 15-25 MPH WITH HIGHER GUSTS/MIN
   RH VALUES BELOW 15 PERCENT/DRY FUELS
   
   MAX TEMPS WILL AGAIN RISE INTO THE 80S/90S ACROSS MUCH OF THE
   REGION...AS MINIMUM RH VALUES FALL INTO THE SINGLE DIGITS ON
   WEDNESDAY AFTN. NUMERICAL GUIDANCE AND FORECAST SOUNDINGS SUGGEST
   MINIMUM RH VALUES COULD BE AS LOW AS 5 PERCENT WITH SFC DEWPOINT
   DEPRESSION VALUES ON THE ORDER OF 60-70 DEGREES. THE WINDIEST
   CONDITIONS WILL EXTEND FROM ERN TREASURE VALLEY IN ID THROUGH THE
   WIND RIVER BASIN IN WY. IN THIS CORRIDOR...SUSTAINED WINDS OF 20-30
   MPH ARE LIKELY. FARTHER SOUTH...WINDS MAY NOT BE AS STRONG...BUT
   FREQUENT GUSTS ARE EXPECTED. RECENT FIRE DANGER CLASS OBSERVATIONS
   INDICATE VALUES FROM HIGH TO EXTREME. SCATTERED TSTMS ARE LIKELY
   DURING THE AFTN AND EVENING...MAINLY NORTH OF THE CRITICAL OUTLOOK
   AREA...ALONG THE DIVIDE AND ACROSS THE SAWTOOTHS AND TETONS.
   
   ...ERN AZ/WRN NM...
   MID LEVEL MOISTURE WILL BE MORE ABUNDANT ON WEDNESDAY ACROSS THE
   SOUTHWEST...AND THERE SHOULD BE AN INCREASE IN DRY TSTMS. FORECAST
   SOUNDINGS INDICATE DEEP INVERTED-V PROFILES...WITH VERY LOW SFC RH
   VALUES. COVERAGE SHOULD BE SLIGHTLY GREATER RELATIVE TO TUESDAY
   WHICH WILL INCREASE RISK OF IGNITIONS ESPECIALLY ALONG AND WEST OF
   THE DIVIDE.
