   VALID 271200Z - 281200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR PARTS OF THE TX RIO GRANDE VALLEY
   AND S CENTRAL TX...
   
   ...SYNOPSIS...
   A S/W TROUGH LOCATED OVER AZ EARLY FRIDAY MORNING WILL PIVOT S AND E
   AROUND A CLOSED MID LEVEL LOW...AND EJECT INTO THE SRN PLAINS DURING
   THE AFTERNOON. MEANWHILE...SURFACE LOW PRESSURE OVER WRN TX WILL
   ACCELERATE EWD AHEAD OF THE UPPER DISTURBANCE ALONG A STATIONARY
   FRONT INTO NE TX. A COLD FRONT TRAILING THE SURFACE LOW IS FORECAST
   TO MOVE SOUTH ACROSS SRN TX DURING THE MID TO LATE AFTERNOON. STRONG
   AND GUSTY WINDS WILL DEVELOP ALONG AND BEHIND THE ADVANCING COLD
   FRONT...WHILE RH VALUES FALL INTO THE TEENS DURING MAXIMUM DAYTIME
   HEATING. FARTHER WEST...SURFACE HIGH PRESSURE WILL BECOME SITUATED
   OVER THE GREAT BASIN IN THE WAKE OF THE CENTRAL CONUS
   TROUGH...LEADING TO STRENGTHENING OFFSHORE FLOW OVER PORTIONS OF SRN
   CA. THESE WINDS WILL COMBINE WITH MILD TEMPERATURES AND DRYING
   SURFACE CONDITIONS THROUGH THE MORNING AND INTO THE AFTERNOON.
   
   ...CRITICAL FIRE WEATHER AREA - PARTS OF THE TX RIO GRANDE VALLEY
   AND S CENTRAL TX...
   
   PRIMARY CONDITIONS: STRONG WINDS...LOW RH...EXTREME DROUGHT
   
   SURFACE WINDS EARLY FRIDAY MORNING HAVE BACKED TO EAST-SOUTHEASTERLY
   ACROSS THE CRITICAL OUTLOOK AREA IN RESPONSE TO THE APPROACHING
   UPPER LEVEL TROUGH...DRAWING HIGHER SURFACE MOISTURE WEST.
   HOWEVER...THIS MOISTURE WILL BE REPLACED BY A MUCH DRIER AIRMASS
   /EVIDENT BY SINGLE DIGIT DEWPOINTS RESIDING OVER SWRN TX/ AS A COLD
   FRONT OVER NM MOVES SOUTH ACROSS THE REGION DURING THE EARLY TO MID
   AFTERNOON. THIS DRY AIR COMBINED WITH AFTERNOON HEATING /HIGHS IN
   THE 70S TO LOW 80S/ WILL ALLOW RH VALUES TO DROP INTO THE TEENS.
   SUSTAINED NORTH-NORTHWESTERLY WINDS UP TO 25 MPH /WITH GUSTS UP TO
   35 MPH/ WILL SPREAD SOUTH ACROSS THE REGION AFTER THE FRONTAL
   PASSAGE...FAVORING CRITICAL FIRE WEATHER CONDITIONS ACROSS PORTIONS
   OF THE RIO GRANDE RIVER VALLEY AND S CENTRAL TX. DUE TO RECENT
   RAINFALL OVER LOCATIONS FARTHER E-NE...THE CRITICAL OUTLOOK AREA HAS
   BEEN CONFINED TO A RELATIVELY SMALL SPATIAL AREA...THOUGH STRONG
   WINDS ACROSS THE ENTIRE REGION WILL ENHANCE RATE OF SPREAD. AS THE
   COLD FRONT CONTINUES TO ADVANCE SOUTH OF THE REGION DURING THE
   EVENING...WIND SPEEDS ARE FORECAST TO REMAIN STRONG...BUT RH
   RECOVERY IS EXPECTED AS TEMPERATURES COOL.
   
   ..PORTIONS OF SRN CA..
   SUSTAINED WIND SPEEDS OF 20 MPH /WITH LOCALLY HIGHER GUSTS/ WILL BE
   POSSIBLE OVER PORTIONS OF SRN CA. WARM TEMPERATURES WILL FAVOR RH
   VALUES IN THE TEENS...RESULTING IN HEIGHTENED FIRE WEATHER DANGER.
   HOWEVER...GENERALLY UNFAVORABLE FUEL CONDITIONS COMBINED WITH THE
   ISOLATED NATURE OF FAVORABLE FIRE WEATHER PARAMETERS WILL PRECLUDE
   THE ISSUANCE OF AN OUTLOOK AREA.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0346 AM CDT FRI MAR 27 2009
   
   VALID 281200Z - 291200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER LEVEL TROUGH WILL MOVE FROM THE SRN PLAINS AT THE BEGINNING
   OF THE D2 PERIOD INTO THE OH VALLEY REGION DURING THE NIGHT...AND
   WILL BE ACCOMPANIED BY A LARGE FRONTAL WAVE. RELATIVELY COLD
   TEMPERATURES ARE EXPECTED TO RESIDE ACROSS THE PLAINS...WHILE MOIST
   SOUTHERLY FLOW OCCURS OVER THE SERN STATES. DAYTIME HEATING OVER S
   CENTRAL TX AND THE RIO GRANDE VALLEY MAY RESULT IN RH VALUES FALLING
   INTO THE TEENS...BRIEFLY BECOMING JUXTAPOSED WITH SUSTAINED WINDS
   AROUND 20 MPH. HOWEVER...CONDITIONS WILL GENERALLY BE TOO MARGINAL
   TO WARRANT A CRITICAL FIRE WEATHER OUTLOOK AREA.
