   ...CRITICAL FIRE WEATHER AREA FOR MUCH OF TX...SERN NM...
   
   ...SYNOPSIS...
   STRONG CYCLONE WILL SHIFT NEWD ACROSS THE UPPER MS VALLEY WITH
   NEGATIVELY TILTED UPPER TROUGH. SURFACE COLD FRONT WILL EXTEND SWD
   FROM THE LOW CENTER THROUGH THE MS VALLEY AT MIDDAY. COOLER AND
   DRIER AIR WILL EXIST BEHIND THIS FRONT...WITH STRONG WINDS AND LOW
   RH PRODUCING CRITICAL FIRE CONDITIONS OVER THE SRN PLAINS.
   ELSEWHERE...MOISTURE LEVELS WILL INCREASE SIGNIFICANTLY ACROSS THE
   SERN STATES AHEAD OF THE COLD FRONT WITH THREAT OF SEVERE WEATHER.
   
   ...CRITICAL FIRE WEATHER AREA - ALL OF WRN...CNTRL...AND SRN
   TX...FAR SERN NM...
   
   PRIMARY CONDITIONS: STRONG WINDS AND VERY LOW RH
   
   SURFACE COLD FRONT WILL MOVE RAPIDLY OUT OF E TX EARLY THIS
   MORNING...WITH HIGH PRESSURE BUILDING IN BEHIND. WLY WINDS WILL
   QUICKLY INCREASE TO 15-25 MPH WITH HIGHER GUSTS...SUNNY SKIES AND
   STRONG MIXING. VERY LOW DEWPOINTS AND HEATING WILL CAUSE RH LEVELS
   TO REACH EXTREME LEVELS OVER MUCH OF THE AREA...WITH SINGLE DIGIT
   READINGS COMMON FROM SERN NM ACROSS CNTRL AND SRN TX. HIGHER VALUES
   OF 15-25 PERCENT WILL OCCUR OVER SERN TX...ALONG WITH STRONG WNWLY
   WINDS.
   
   THE GREATEST FIRE THREAT WILL BE ACROSS MUCH OF WCNTRL AND SWRN TX
   WHERE KBDI VALUES ARE BETWEEN 500-700. DROUGHT INDICATORS ARE MUCH
   LESS DRY ACROSS ERN TX...HOWEVER...LOW RH AND STRONG WINDS WILL POSE
   A THREAT OF GRASS FIRES.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0230 AM CST THU MAR 01 2007
   
   VALID 021200Z - 031200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A BROAD UPPER TROUGH WILL STRETCH FROM THE ROCKIES TO THE E COAST
   WITH LOW PRESSURE SYSTEM CENTERED OVER THE WRN GREAT LAKES FRI
   AFTERNOON. A DRY AIR MASS WITH HIGH PRESSURE WILL EXTEND FROM THE
   GREAT BASIN EWD ACROSS THE SRN ROCKIES AND SRN PLAINS WITH AN
   AMPLIFYING SHORTWAVE TROUGH SINKING SWD INTO THE CNTRL ROCKIES LATE
   IN THE PERIOD.
   
   ...SRN CA INTO SRN AZ...
   AN UPPER RIDGE WILL BEGIN TO BUILD ALONG THE W COAST LATE IN THE
   PERIOD FRI...AS A SWD MOVING SHORTWAVE EMBEDDED WITHIN LARGE SCALE
   TROUGH DIVES SWD THROUGH THE CNTRL ROCKIES. THIS WILL HELP TO BRING
   HIGH PRESSURE/COLD FRONT SWD THROUGH THE GREAT BASIN AND ACROSS
   AZ/NM...TIGHTENING PRESSURE GRADIENTS. THIS WILL RESULT IN INCREASED
   NLY/NELY FLOW OVER SWRN AZ INTO SRN CA. ENOUGH OF A GRADIENT WILL
   EXIST FOR SANTA ANA WINDS LATE FRI INTO EARLY SAT OVER SRN
   CA...HOWEVER...COOL TEMPERATURES WILL RESULT IN MARGINALLY LOW RH
   VALUES. IN ADDITION TO MARGINALITY OF RH...EFFECTS OF RECENT
   PRECIPITATION WILL LIKELY DAMPER OVERALL FIRE THREAT AT LEAST
   THROUGH SAT MORNING...ALTHOUGH IT WILL BE ON THE INCREASE WITH TIME
   AS DRY WEATHER PERSISTS.
   
   ...CNTRL AND SWRN TX...
   A DRY AIR MASS WITH HIGH PRESSURE WILL RESIDE ACROSS TX WITH ONLY
   WEAK WLY WINDS AROUND 10 MPH. MIN RH VALUES WILL REMAIN QUITE LOW
   FROM 10-20 PERCENT WITH WARMING TEMPERATURES INTO THE 60S AND LOWER
   70S. GIVEN STEEP LOW LEVEL LAPSE RATES DURING THE AFTERNOON AND LOW
   RH...FIRE THREAT WILL BE HEIGHTENED WITH POSSIBLE FLARE UPS OF ANY
   EXISTING FIRES.
