   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0239 AM CST SAT FEB 07 2009
   
   VALID 071200Z - 081200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   EARLY MORNING SATELLITE IMAGERY SHOWS AN UPPER TROUGH AND CLOSED LOW
   OVER PARTS OF THE W COAST WITH SHORTWAVE UPPER RIDGING OCCURRING
   DOWNSTREAM OVER PARTS OF THE HIGH PLAINS.  A SURFACE HIGH PRESSURE
   RIDGE WILL DOMINATE WEATHER CONDITIONS OVER PARTS OF THE SERN
   U.S...WHERE LOW RH AND RELATIVELY WEAK WINDS WILL AGAIN RESIDE.  THE
    ONSHORE PUSH OF MORE MOIST AND BREEZY CONDITIONS OVER TX WILL
   SLACKEN COMPARED TO FRIDAY AS A DEPARTING TROUGH OVER THE GREAT
   LAKES LIFTS NEWD AWAY FROM THE REGION.  HOWEVER...STRONGER ONSHORE
   FLOW WILL RESUME DURING THE LATTER HALF OF THE PERIOD IN RESPONSE TO
   THE APPROACHING UPPER TROUGH FROM THE SWRN STATES.
   
   ...PARTS OF CENTRAL AND DEEP S TX...
   GUSTY WINDS WILL LIKELY DEVELOP DURING THE AFTERNOON HOURS AS A
   MODIFIED CP AIRMASS RECIRCULATES THROUGH THE GULF BASIN.  A STRONG
   CAPPING INVERSION WILL LIKELY EXIST...LIMITING POTENTIAL FOR DEEP
   MIXING AND LOW RH.  NONETHELESS...GUSTY WINDS WILL SERVE TO ELEVATE
   THE FIRE WEATHER THREAT ACROSS DROUGHT-STRICKEN AREAS.
   
   ...PARTS OF THE SERN U.S...
   RELATIVELY DRY AIRMASS WILL LEAD TO LOW MIN RH DURING THE AFTERNOON
   HOURS BEFORE RECOVERING DURING THE EVENING.  RH VALUES DIPPING INTO
   THE 30S/20S WILL BE COMMON IN LOCALES.  GENERALLY WEAK ELY SUSTAINED
   WINDS /BELOW 15 MPH/ OVER THE FL PENINSULA VEERING TO SLY OVER GA/AL
   WILL LIMIT THE OVERALL FIRE WEATHER THREAT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0335 AM CST SAT FEB 07 2009
   
   VALID 081200Z - 091200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER TROUGH WITH AN ASSOCIATED CLOSED UPPER LOW LOCATED OVER
   PARTS OF THE SWRN STATES AT THE BEGINNING OF THE PERIOD WILL EJECT
   EWD INTO THE PLAINS REGION D2.  THE APPROACHING UPPER SYSTEM WILL
   LEAD TO STRENGTHENING FLOW FIELDS ALOFT /70KT AT 500MB FLOW/
   OVERSPREADING THE REGION ON SUNDAY.  THIS SYSTEM WILL INDUCE LEE
   SIDE TROUGHING OVER THE SRN HIGH PLAINS LEADING TO A STRENGTHENING
   PRESSURE GRADIENT ACROSS THE CENTRAL STATES AND A PACIFIC COLD FRONT
   WILL PUSH EWD ACROSS THE SRN ROCKIES INTO THE SRN HIGH PLAINS. 
   AHEAD OF THIS FEATURE...MODERATELY STRONG...YET RELATIVELY MOIST
   SELY LOW LEVEL FLOW WILL ADVECT NWWD INTO PARTS OF THE SRN HIGH
   PLAINS.
   
   ...SWRN TX /BIG BEND AREA/...
   BEHIND THE DRYLINE AND AHEAD OF THE EWD SWEEPING COLD
   FRONT...POTENTIAL EXISTS FOR CRITICAL FIRE WEATHER CONDITIONS DUE TO
   STRONG SUSTAINED WINDS /20-25 MPH/ AND LOW RH.  LARGE MODEL
   VARIABILITY DEPICTING THE EVOLUTION OF THE BOUNDARY LAYER AND
   POTENTIAL MIXING HAS RESULTED IN APPRECIABLE UNCERTAINTY REGARDING
   THE MAGNITUDE OF MIN RH.  NONETHELESS...THE STRENGTH OF THE
   BACKGROUND WIND FIELDS WILL SUPPORT AN ENHANCED FIRE WEATHER THREAT
   DESPITE AN APPRECIABLE PROBABILITY THAT MARGINAL RH VALUES REMAIN
   AOA 20 PERCENT.
