   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0142 AM CDT THU MAR 18 2010
   
   VALID 181200Z - 191200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER LEVEL TROUGH IS FORECAST TO DIG SWD INTO THE INTERMOUNTAIN
   WEST ON THURSDAY...WHILE A RIDGE TO ITS EAST BEGINS TO BREAK DOWN
   OVER THE GREAT PLAINS. AS THIS TAKES PLACE...LOW PRESSURE WILL
   DEEPEN OVER ERN CO...RESULTING IN STRENGTHENING S-SWLY LOW LEVEL
   FLOW ACROSS AZ/NM INTO PORTIONS OF THE SRN AND CENTRAL HIGH PLAINS.
   FARTHER W ALONG THE BACKSIDE THE TROUGH...SURFACE HIGH PRESSURE IS
   FORECAST TO DROP SWD INTO THE GREAT BASIN...WHILE A TROUGH OF LOW
   PRESSURE DEVELOPS NWD THROUGH THE CENTRAL VALLEY OF CA DURING THE
   AFTERNOON...WHICH WILL FAVOR POTENTIALLY WINDY DOWNSLOPE WINDS
   ACROSS PORTIONS OF NRN CA.
   
   ...PORTIONS OF NERN NM AND THE TX/OK PANHANDLES NWD INTO SERN CO AND
   SWRN KS...
   
   MODEL GUIDANCE CONTINUES TO INDICATE STRENGTHENING S-SWLY SURFACE
   WINDS...SUSTAINED UP TO 20 MPH...OVER PORTIONS OF THE SRN/CENTRAL
   PLAINS DURING THURSDAY AFTERNOON AS THE PRESSURE GRADIENT
   STRENGTHENS IN RESPONSE TO DEEPENING LOW PRESSURE OVER ERN CO.
   HOWEVER...MIN RH VALUES ONLY FALLING INTO THE 20S AND 30S...ALONG
   WITH MARGINAL FUEL CONDITIONS...SHOULD PRECLUDE THE DEVELOPMENT OF
   CRITICAL FIRE WEATHER CONDITIONS.

   DAY 2 FIRE WEATHER OUTLOOK CORR 1

   CORRECTED FOR CRITICAL AREA HEADER
   
   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SRN/SERN NM AND SW
   TX...
   
   ...SYNOPSIS...
   SURFACE LOW PRESSURE INITIALLY LOCATED OVER ERN CO...IS FORECAST TO
   EJECT EWD INTO THE GREAT PLAINS AS AN UPPER LEVEL TROUGH APPROACHES
   THE CENTRAL/SRN ROCKIES. A COLD FRONT WILL MOVE S AND E INTO THE SRN
   PLAINS AS THIS TAKES PLACE...WITH A SECONDARY SURFACE LOW FORMING
   ALONG THE FRONT OVER W TX. WARM...DRY...WLY WINDS ARE EXPECTED TO
   DEVELOP OVER SRN NM AND SW TX AS STRONGER MID LEVEL FLOW SPREADS EWD
   FROM THE BASE OF THE TROUGH...LEADING TO A PERIOD OF POSSIBLE
   CRITICAL FIRE WEATHER CONDITIONS.
   
   ...CRITICAL FIRE WEATHER AREA - PORTIONS OF SRN/SERN NM AND SW TX...
   
   PRIMARY CONDITIONS: LOW RH AND STRONG WINDS
   
   MODEL GUIDANCE IS BEGINNING TO TREND SLIGHTLY WEAKER WITH MID LEVEL
   WLY FLOW SPREADING E FROM THE BASE OF AN APPROACHING UPPER
   TROUGH...ALONG WITH WEAKER DEEPENING OF A SURFACE LOW OVER W TX. AS
   A RESULT...SUSTAINED WIND SPEEDS ALONG WITH DOWNSLOPE WARMING/DRYING
   APPEAR MORE MARGINAL FOR CRITICAL FIRE WEATHER CONDITIONS ACROSS
   PORTIONS OF SRN/SERN NM AND SW TX. HOWEVER...AN OUTLOOK AREA WILL BE
   MAINTAINED FOR RH VALUES NEAR 15 PERCENT AND SUSTAINED WIND SPEEDS
   APPROACHING 20-25 MPH DURING THE AFTERNOON...PRIMARILY FOR LOWER
   ELEVATIONS /GIVEN THAT FUELS WILL POTENTIALLY BE MORE MARGINAL IN
   THE HIGHER MOUNTAINOUS TERRAIN/.
