   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK

   VALID 111200Z - 121200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR CENTRAL AND SRN NV...SWRN
   UT...NWRN AZ...
   
   ...SYNOPSIS...
   VERY HOT AND DRY CONDITIONS WILL PREVAIL OVER MUCH OF THE SRN AND
   SWRN PORTIONS OF THE NATION UNDER AN UPPER RIDGE. TO THE
   WEST...UPPER TROUGH WILL DIG ALONG THE PACIFIC COAST AND WILL CAUSE
   INCREASED WINDS INTO THE GREAT BASIN. MEANWHILE...HIGH PRESSURE
   ACROSS THE SERN STATES WILL KEEP CONDITIONS HOT AND DRY...WITH
   CONTINUED HOT SLY WINDS ACROSS THE SRN PLAINS ON WRN EDGE OF HIGH
   AND E OF SRN HIGH PLAINS THERMAL LOW.
   
   ELSEWHERE...HEAVY RAINS WILL OCCUR ALONG A FRONTAL BOUNDARY FROM KS
   EWD INTO THE OH AND TN VALLEYS...AND HUMIDITIES WILL BE ON THE RISE
   ACROSS THE FL PENINSULA WITH TROPICAL SYSTEM IN THE VICINITY.
   
   ...CRITICAL FIRE WEATHER AREA - CENTRAL AND SRN NV...SWRN UT...NWRN
   AZ...
   
   PRIMARY CONDITIONS: STRONG WIND GUSTS / VERY LOW RH AND HOT
   TEMPERATURES
   
   SLY FLOW ALOFT WILL BEGIN TO STRENGTHEN TODAY IN RESPONSE TO
   AMPLIFYING UPPER TROUGH ENTERING THE WRN GREAT BASIN. STRONG HEATING
   AND WARM TEMPERATURES WILL HELP BRING RH DOWN TO AROUND 10 PERCENT
   IN THE AFTERNOON. SUSTAINED WINDS WILL AVERAGE CLOSE TO 20 MPH...BUT
   GUSTS WILL BE STRONGER FROM 20-30 MPH DUE TO DEEP MIXING. MDT TO
   HIGH HAINES WILL ENHANCE DEEP FIRE PLUME POTENTIAL AS WELL.
   OVERNIGHT...RH RECOVERY WILL REMAIN POOR MOST AREAS WITH GUSTY WINDS
   NEAR RIDGE TOPS AS TROUGH NEARS.
   
   ...CENTRAL AND ERN AZ INTO WRN NM...
   AN EXTREMELY DRY AIR MASS WILL REMAIN IN PLACE TODAY BENEATH UPPER
   RIDGE WITH RH LEVELS OF 5-10 PERCENT DURING THE AFTERNOON.
   THIS...ALONG WITH VERY STEEP LAPSE RATES WILL MAXIMIZE LOW TO MID
   LEVEL INSTABILITY WITH AN ENVIRONMENT FAVORABLE FOR PLUME DOMINATED
   FIRES BY LATE IN THE DAY /HIGH HAINES INDEX/. ALTHOUGH SUSTAINED
   WINDS OF 10-15 MPH ARE BELOW CRITICAL LEVELS ON THE LARGE
   SCALE...LOCALIZED AREAS IN AND AROUND ONGOING WILD FIRES SHOULD BE
   TREATED AS CRITICAL DUE TO POTENTIAL FOR GROWTH OF ONGOING FLAMES.
   
   ...GA AND SC...
   A VERY HOT AIR MASS WILL REMAIN ACROSS THE REGION TODAY...ALBEIT
   BENEATH A WEAKENING UPPER RIDGE DUE TO IMPINGING TROUGH TO THE NORTH
   AND WEAK TROPICAL SYSTEM TO THE SOUTH. NEVERTHELESS...TEMPERATURES
   WILL NEAR 100 DEGREES WHICH WILL BRING RH LEVELS DOWN INTO THE 20
   PERCENT RANGE. WINDS WILL BE STRONGER TODAY THAN PREVIOUS DAY DUE TO
   A WEAK LOW PRESSURE AREA DEVELOPING INTO THE CAROLINAS SOUTH OF A
   FRONTAL BOUNDARY. SUSTAINED SPEEDS OF 10-15 MPH WILL BE COMMON...BUT
   SOME HIGHER GUSTS OVER 20 MPH MAY OCCUR DUE TO STRONG AND DEEP
   MIXING LAYERS. GIVEN THESE FORECAST PARAMETERS...CONDITIONS WILL BE
   NEAR CRITICAL LEVELS DURING THE AFTERNOON. SIMILAR TEMPERATURES AND
   RH WILL EXIST INTO AL AND MS...BUT WINDS WILL BE WEAKER.
   
   ...WRN OK INTO NWRN TX...
   A THERMALLY INDUCED LOW PRESSURE TROUGH WILL EXTEND FROM THE OK/TX
   PANHANDLES SWD INTO SWRN TX UNDERNEATH UPPER RIDGE AXIS. E OF THIS
   AXIS...SURFACE GRADIENT WILL SUPPORT SLY WIND SPEEDS AROUND 15 MPH
   WITH HIGHER GUSTS FROM TX INTO OK. IT WILL BE VERY HOT IN THESE
   AREAS WITH TEMPERATURES OF 96-104 AND MIN RH OF 20-25 PERCENT. A
   NEAR CRITICAL THREAT MAY EXIST DURING THE LATE AFTERNOON IN AREAS
   THAT HAVE HAD RELATIVELY LITTLE PRECIPITATION RECENTLY.

   VALID 121200Z - 131200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR MUCH OF NV AND UT...NRN AZ AND
   SERN CA DESERTS...
   
   ...SYNOPSIS...
   UPPER TROUGH WILL CONTINUE TO AMPLIFY ACROSS THE FAR WRN STATES
   BRINGING INCREASING WINDS INTO THE GREAT BASIN WHERE IT WILL REMAIN
   VERY HOT AND DRY. THIS SAME AIR MASS WILL EXTEND EWD INTO THE
   CENTRAL AND SRN ROCKIES AS WELL AS THE SRN PLAINS BENEATH BUILDING
   UPPER RIDGE.  MUCH NEEDED RAIN WILL OCCUR ACROSS THE SERN STATES AS
   TROPICAL MOISTURE MOVES NWD.
   
   ...CRITICAL FIRE WEATHER AREA - MUCH OF NV AND UT...NRN AZ AND SERN
   CA DESERTS...
   
   PRIMARY CONDITIONS: STRONG WINDS / VERY LOW RH / HIGH HAINES
   
   WINDS WILL INCREASE FURTHER ON MONDAY...BRINGING FIRE DANGER TO
   EXTREME LEVELS. SUSTAINED WINDS OF 20-30 MPH WILL BE LIKELY ALONG
   WITH HIGHER GUSTS WHILE RH REMAINS VERY LOW FROM THE UPPER SINGLE
   DIGITS TO LOWER TEENS. IN ADDITION...HAINES INDEX WILL BE HIGH OVER
   MOST OF THE CRITICAL AREA. WINDS WILL REMAIN QUITE STRONG OVERNIGHT
   IN THE HIGH TERRAIN WITH POOR RH RECOVERY.
   
   ...REMAINDER OF AZ...MUCH OF NM...WRN CO...
   NEAR CRITICAL CONDITIONS WILL EXIST DUE TO CONTINUED VERY HOT AND
   DRY CONDITIONS...WITH POTENTIAL FOR PLUME DOMINATED FIRES DURING THE
   AFTERNOON WITH HIGH HAINES INDEX. MAIN UPPER TROUGH ENERGY WILL
   REMAIN TO THE W...BUT STRONG MIXING WILL ALLOW FOR LOCALLY STRONG
   AFTERNOON WIND GUSTS OF 15-25 MPH WHILE SUSTAINED SPEEDS REMAIN AT
   OR BELOW 15 MPH.
