   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0339 AM CST WED FEB 11 2009
   
   VALID 111200Z - 121200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   POTENT UPPER-LEVEL SHORT WAVE TROUGH OVER THE SRN PLAINS WILL
   RAPIDLY EJECT NEWD INTO THE NORTHEAST. ATTENDANT SURFACE COLD FRONT
   WILL SWEEP EWD ACROSS THE LOWER/MIDDLE-MS RIVER VALLEY AND THROUGH
   THE ERN SEABOARD BY EARLY THU. AN UPSTREAM SHORT WAVE TROUGH OFF THE
   PACIFIC NW COAST WILL DROP SWD INTO CA.
   
   ...S-CNTRL/DEEP S TX...
   GUSTY NWLY WINDS HAVE ACCOMPANIED STRONG PRESSURE RISES IN THE WAKE
   OF A COLD FRONT PASSAGE EARLY THIS MORNING. THIS HAS RESULTED IN
   SUBSTANTIAL DRYING WITH AREAS OF RH VALUES FALLING TO BETWEEN 10 AND
   20 PERCENT. ALTHOUGH SOME RECOVERY WILL OCCUR THROUGH DAYBREAK GIVEN
   CAA AND RADIATIVE COOLING...LOW RH SHOULD BECOME WIDESPREAD TOWARDS
   NOON. HOWEVER...LOW-LEVEL FLOW HAS BEGUN TO WEAKEN UPSTREAM /AS
   NOTED IN DEL RIO VAD PROFILER/...AND SHOULD MARKEDLY DECREASE LATER
   THIS MORNING AS THE CYCLONE CENTERED OVER N-CNTRL OK ACCELERATES
   NEWD. THIS SUGGESTS THE CRITICAL THREAT SHOULD BE SHORT-LIVED AND
   DOES NOT APPEAR SUFFICIENT TO WARRANT AN AREAL ISSUANCE.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0341 AM CST WED FEB 11 2009
   
   VALID 121200Z - 131200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   PROGRESSIVE UPPER-LEVEL PATTERN WILL CONTINUE WITH A SHORT WAVE
   TROUGH EVOLVING EWD FROM CA TOWARDS THE CNTRL/SRN HIGH PLAINS...AND
   A VIGOROUS UPSTREAM SHORT WAVE TROUGH DIGGING ALONG THE PACIFIC
   NW/NRN CA COAST. IN ADVANCE OF THE INITIAL WAVE...A LEE CYCLONE
   SHOULD BECOME CENTERED OVER NERN NM THU AFTERNOON.
   
   ...S-CNTRL/SERN NM AND FAR W TX...
   SWLY LOW-LEVEL FLOW WILL STRENGTHEN AS A SHORT WAVE TROUGH
   APPROACHES THE FOUR CORNERS DURING THE DAY THU. SUSTAINED SURFACE
   WINDS WILL LIKELY BREACH 20 MPH IN THE LATE AFTERNOON AND THIS
   SHOULD BE JUXTAPOSED WITH RH VALUES FROM 10 TO 15 PERCENT.
   HOWEVER...OVERALL DURATION OF THE STRONG WINDS APPEARS TOO MARGINAL
   TO WARRANT A CRITICAL AREA.
   
   ...LOW ROLLING PLAINS/EDWARDS PLATEAU OF TX...
   A VERY DRY ANTECEDENT AIR MASS WILL BE IN PLACE AS LOW-LEVEL RETURN
   FLOW STRENGTHENS WITH A LEE CYCLONE DEEPENING OVER NERN NM.
   ABOVE-NORMAL TEMPERATURES WARMING INTO THE 70S WILL RESULT IN LOW RH
   FROM 10 TO 15 PERCENT. ALTHOUGH MODEL FORECAST SOUNDINGS INDICATE
   INCREASING SLY LOW-LEVEL FLOW BENEATH AN ELEVATED MIXED LAYER...THEY
   DIFFER MORE SUBSTANTIALLY WITH THE STRENGTH OF THE WINDS. CONSENSUS
   WOULD SUGGEST SUSTAINED SURFACE WINDS MAY BRIEFLY REACH 20 MPH AND
   COULD RESULT IN A LOCALIZED/SHORT-DURATION CRITICAL THREAT.
