   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0450 AM CDT MON MAY 21 2007
   
   VALID 211200Z - 221200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR NRN AZ/WRN CO/SRN AND ERN UT...
   
   ...SYNOPSIS...
   EARLY MORNING WATER VAPOR LOOPS SHOW CLOSED UPPER LOW NOW
   APPROACHING THE COLUMBIA BASIN IN WA/ORE. THIS SYSTEM WILL MOVE E/SE
   TODAY AND BE LOCATED IN WRN WY BY EARLY TUE. MID LEVEL JET STREAK
   WILL ACCOMPANY THE UPPER LOW...WITH WINDS INCREASING TO 60-70 KT
   ACROSS THE GREAT BASIN. IN THE ERN CONUS...UPPER RIDGE WILL AMPLIFY
   IN RESPONSE TO WRN STORM. SFC LOW WILL DEEPEN ACROSS THE WRN DAKOTAS
   WITH COLD FRONT EXTENDING SWWD FROM THE LOW INTO SCNTRL UT/SRN NV BY
   LATE AFTN. SFC HIGH PRESSURE WILL GRADUALLY WEAKEN OVER THE TN
   VALLEY BUT VERY LOW HUMIDITY VALUES WILL ENHANCE FIRE CONCERNS IN
   THE SOUTHEAST.
   
   ...CRITICAL FIRE WEATHER AREA - NRN AZ/WRN CO/SRN AND ERN UT...
   
   PRIMARY CONDITIONS: SUSTAINED WINDS 15-25 MPH WITH HIGHER GUSTS/MIN
   RH VALUES BELOW 15 PERCENT/LONG TERM DROUGHT/ISOLD DRY TSTMS
   
   SFC COLD FRONT EXTENDED SW FROM A LOW IN CNTRL WY THROUGH NRN UT AND
   SE OF ELKO NV THIS MORNING. SOUTH OF THIS BOUNDARY TODAY...WINDS ARE
   EXPECTED TO INCREASE TO AT LEAST 15-25 MPH...ESPECIALLY ACROSS
   PORTIONS OF SRN UT/NRN AZ AND WRN CO. INVOF OF THE FRONT...THERE
   WILL BE A SHARP WIND SHIFT AS WINDS BECOME W/NW AND REMAIN GUSTY
   BEHIND THE FRONT. MAX TEMPS WILL RANGE FROM THE 80S/90S IN THE LOWER
   TERRAIN SOUTH OF THE FRONT AND 60S/70S NORTH OF THE FRONT OR IN
   HIGHER ELEVATIONS...BUT MIN RH VALUES ACROSS THE REGION WILL FALL
   BELOW 15 PERCENT. SINGLE DIGIT HUMIDITY VALUES ARE LIKELY ACROSS SRN
   UT/WRN CO. SUFFICIENT MID LEVEL MOISTURE WILL ALSO BE PRESENT TO
   SUPPORT ISOLD TSTMS. THIS WILL BE MOST LIKELY INVOF OF THE
   FRONT...FROM ECNTRL NV INTO WRN/CNTRL UT. GIVEN RELATIVELY HIGH
   BASES OF TSTMS AND DRY SUB-CLOUD LAYER...ISOLD DRY LIGHTNING STRIKES
   ARE POSSIBLE.
   
   ...PLAINS...
   VERY STRONG WINDS ARE FORECAST TODAY ACROSS THE PLAINS WITH SPEEDS
   RANGING FROM 20-30 MPH WITH HIGHER GUSTS. HOWEVER...MINIMUM RH
   VALUES WILL REMAIN ABOVE CRITICAL LEVELS IN MOST LOCATIONS. THE
   DRIEST CONDITIONS WILL BE ACROSS THE NEB PANHANDLE AND WRN
   DAKOTAS...WHERE MODERATE LONG TERM DROUGHT PERSISTS. THERE WILL BE
   AN ELEVATED RISK FOR WIND DRIVEN WILDFIRES IF IGNITIONS OCCUR. 
   
   ...SOUTHEAST...
   MINIMUM RH VALUES WILL FALL BELOW 20 PERCENT ACROSS PORTIONS OF THE
   CAROLINAS/GA/AL/FL PANHANDLE. THE WINDS WILL BE LIGHT AND VARIABLE
   FOR MOST OF THIS REGION. SLIGHTLY STRONGER ELY WINDS ARE LIKELY
   ACROSS THE ERN COASTAL AREAS OF FL BUT HIGHER HUMIDITY WILL HELP
   OFFSET THE FIRE IMPACT OF THE WINDS.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0454 AM CDT MON MAY 21 2007
   
   VALID 221200Z - 231200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR SRN GA/CNTRL AND ERN FL
   PANHANDLE/CNTRL FL...
   
   ...SYNOPSIS...
   WRN UPPER TROUGH WILL MOVE ACROSS THE NRN ROCKIES ON TUE AS LARGE
   MID LEVEL RIDGE BUILDS ACROSS ONTARIO/QUEBEC. SFC LOW PRESSURE WILL
   DEEPEN IN RESPONSE TO LARGE SCALE HEIGHT FALLS ACROSS THE
   PLAINS...AND STRONG GRADIENT WILL RESULT IN WINDY CONDITIONS ACROSS
   THE PLAINS AND UPPER MIDWEST. SFC WINDS WILL ALSO INCREASE FROM THE
   EAST ACROSS GA/FL...WITH CRITICAL FIRE CONDITIONS POSSIBLE TUE AFTN.
   
   ...CRITICAL FIRE WEATHER AREA - SRN GA/CNTRL AND ERN FL
   PANHANDLE/CNTRL FL...
   
   PRIMARY CONDITIONS: MINIMUM RH VALUES BELOW 35 PERCENT/SUSTAINED
   WINDS 15-20 MPH/LONG TERM DROUGHT
   
   IT APPEARS MINIMUM RH WILL BE SLIGHTLY HIGHER THAN IN THE LAST FEW
   DAYS...BUT VALUES STILL MAY FALL NEAR OR BELOW 35 PERCENT WITH
   TEMP/DEWPOINT SPREADS ON THE ORDER OF 30 DEGREES. SFC WINDS WILL BE
   STRONGER THAN ON MONDAY...WITH SUSTAINED SPEEDS OF 15-20 MPH
   POSSIBLE. A CRITICAL OUTLOOK WILL BE ISSUED GIVEN NUMEROUS ONGOING
   LARGE FIRES/KBDI VALUES ABOVE 500 AND LOW HUMIDITY COMBINED WITH
   MODERATE TO STRONG WINDS.
   
   ...SRN HIGH PLAINS...
   SFC DRYLINE WILL MIX EWD ON TUE AFTN...WITH CRITICALLY LOW HUMIDITY
   VALUES AND STRONG SW WINDS. HOWEVER...RECENT PRECIPITATION WILL
   OFFSET THE POTENTIAL FOR LARGE FIRES.
