   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0352 AM CST SUN FEB 03 2008
   
   VALID 031200Z - 041200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR MUCH OF THE SRN HIGH PLAINS
   REGION...
   
   ...SYNOPSIS...
   A STRONG UPPER TROUGH WILL DIG SEWD THROUGH THE WEST COAST/GREAT
   BASIN THROUGH TONIGHT. AHEAD OF THIS SYSTEM...STRENGTHENING MID
   LEVEL FLOW COMBINED WITH A DEEPENING SURFACE PRESSURE TROUGH EAST OF
   THE SRN ROCKIES WILL SUPPORT INCREASING SWLY WINDS OVER MUCH OF THE
   SRN HIGH PLAINS REGION. COMBINED WITH LOW RH READINGS...CRITICAL
   FIRE WEATHER CONDITIONS ARE EXPECTED OVER A LARGE PORTION OF THE SRN
   HIGH PLAINS TODAY. ELSEWHERE...WARMING TEMPERATURES UNDER A
   DEVELOPING UPPER RIDGE COMBINED WITH LOW RH READINGS WILL INCREASE
   THE FIRE DANGER OVER THE CAROLINAS/GA. HOWEVER...LIGHT WINDS IN THIS
   AREA WILL NOT SUPPORT A CRITICAL FIRE WEATHER THREAT.
   
   ...CRITICAL FIRE WEATHER AREA - SERN/ECENTRAL NM...MUCH OF WRN
   TX...SWRN OK...
   
   PRIMARY CONDITIONS: SUSTAINED SWLY WINDS FROM 20-30 MPH WITH GUSTS
   OVER 40 MPH IN THE HIGHEST TERRAIN...MIN RH READINGS FROM 10-20
   PERCENT
   
   AHEAD OF A DEEPENING UPPER TROUGH OVER THE GREAT BASIN...SWLY WINDS
   WILL INCREASE OVER THE SRN HIGH PLAINS TODAY. THIS WILL BE IN
   RESPONSE TO INCREASING MID LEVEL FLOW AND A DEEPENING SURFACE LEE
   TROUGH/INCREASING PRESSURE GRADIENT. MEANWHILE...THE THERMAL RIDGE
   IN THE LOW LEVELS WILL BECOME WELL ESTABLISHED OVER THE SRN HIGH
   PLAINS AIDED BY DOWNSLOPE WINDS. THIS WILL SUPPORT ABOVE NORMAL
   TEMPERATURES FROM THE UPPER 50S IN THE GUADALUPE/SACRAMENTO
   MTNS...TO THE MID/UPPER 70S OVER NWRN TX. SFC DEWPTS ARE EXPECTED TO
   RANGE FROM THE TEENS OVER ERN NM/WRN TX TO THE LOWER-MID 20S OVER
   NWRN TX/SWRN OK. THESE DEWPTS WILL SUPPORT MIN RH READINGS FROM
   15-20 PERCENT OVER THE ENTIRE REGION...WITH ISOLATED RH READINGS
   DOWN BELOW 10 PERCENT. THE STRONGEST WINDS ARE EXPECTED TO DEVELOP
   IN THE SACRAMENTO/GUADALUPE MTNS WITH SUSTAINED WINDS FROM 25-35 MPH
   AND GUSTS OVER 40 MPH. SUSTAINED WINDS FORM 20-25 MPH WITH GUSTS
   OVER 30 MPH WILL BE LIKELY OVER THE REMAINDER OF THE CRITICAL AREA.
   
   ...NRN TX PANHANDLE...NWRN/CENTRAL OK....NCENTRAL/CENTRAL TX...
   TO THE NORTH AND EAST OF THE CRITICAL AREA...THE PRESSURE GRADIENT
   WILL BE WEAKER...LIMITING SFC WINDS TO GENERALLY LESS THAN 20 MPH. 
   SLY WINDS WILL AID IN LOW LEVEL MOISTURE INCREASING OVER CENTRAL OK
   SWD INTO CENTRAL TX /GENERALLY EAST OF I-35/. WEST OF I-35...MIN RH
   READINGS FROM 20-30 PERCENT ARE LIKELY AS WELL ABOVE NORMAL
   TEMPERATURES FROM THE MID 60S IN THE NRN TX PANHANDLE/NWRN OK TO THE
   UPPER 70S IN CENTRAL/NCENTRAL TX COMBINE WITH DEWPTS IN THE 20S TO
   LOWER 40S. HOWEVER..MODEST WINDS /15-20 MPH/ WILL PRECLUDE CRITICAL
   FIRE WEATHER CONDITIONS.
   
   ...CAROLINAS/GA...
   BROAD UPPER RIDGING WILL DEVELOP OVER THE AREA TODAY SUPPORTING
   ABOVE NORMAL HIGH TEMPERATURES. WEAK WINDS WILL PREVENT MOISTURE
   RETURN...WITH DEWPTS REMAINING IN THE 20S/30S. AS TEMPERATURES WARM
   INTO THE 65-75 DEG F RANGE...RH READINGS WILL FALL TO BETWEEN 20-30
   PERCENT. HOWEVER...LIGHT WINDS WILL MITIGATE ANY CRITICAL FIRE
   WEATHER THREAT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0354 AM CST SUN FEB 03 2008
   
   VALID 041200Z - 051200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR A PORTION OF THE SRN PLAINS...
   
   ...SYNOPSIS...
   A SEASONABLY STRONG UPPER TROUGH WILL MOVE THROUGH THE SWRN
   STATES/ROCKIES TOMORROW. AHEAD OF THIS TROUGH...STRONG SWLY WINDS
   WILL CONTINUE OVER THE SRN HIGH PLAINS. CRITICAL FIRE WEATHER
   CONDITIONS WILL BE THE RESULT AGAIN...GIVEN THE PRESENCE OF WELL
   ABOVE NORMAL TEMPERATURES/LOW RH READINGS. ELSEWHERE ACROSS THE
   NATION...ABOVE NORMAL TEMPERATURES WILL DEVELOP OVER MUCH OF THE ERN
   CONUS UNDER THE PRESENCE OF A BUILDING UPPER RIDGE. IN RESPONSE TO
   INCREASING SLY WINDS...A MOIST AIRMASS WILL PRECLUDE ANY CRITICAL
   CONCERNS OVER THE SERN STATES.
   
   ...CRITICAL FIRE WEATHER AREA - SWRN TX NEWD INTO WRN/CENTRAL OK...
   
   PRIMARY CONDITIONS: SUSTAINED SWLY WINDS FROM 25-35 MPH WITH GUSTS
   OVER 40 MPH...MIN RH READINGS FROM 15-25 PERCENT
   
   AHEAD OF A SEASONABLY STRONG UPPER TROUGH/COLD FRONT SSWLY WINDS
   WILL INCREASE OVER THE SRN PLAINS TOMORROW. DESPITE STRONGER SFC
   WINDS  /AVERAGING 10 MPH STRONGER THAN SPEEDS TODAY/ INCREASING
   MID-HIGH LEVEL CLOUDS AND SLIGHTLY COOLER TEMPERATURES/HIGHER DEWPTS
   THAN TODAY WILL PRECLUDE AN EXTREMELY CRITICAL OUTLOOK AREA OVER THE
   REGION OF STRONGEST WINDS /WEST TX/. MIN RH READINGS ARE EXPECTED TO
   REACH CRITICAL LEVELS /15-25 PERCENT/ OVER THE ENTIRE CRITICAL
   OUTLOOK AREA DURING THE AFTERNOON...AIDED BY WELL ABOVE NORMAL
   TEMPERATURES FROM THE UPPER 60S TO THE LOWER 80S. A STRONG COLD
   FRONT WILL MOVE SEWD INTO WRN OK/NWRN TX OVERNIGHT SHIFTING WINDS TO
   A NLY DIRECTION AND AIDING IN INCREASING RH READINGS AND DIMINISHING
   CRITICAL FIRE WEATHER CONDITIONS. THE ERN EXTENT OF THE CRITICAL
   AREA OVER CENTRAL/SRN OK IS THE EXPECTED LOCATION OF THE DRYLINE.
   FURTHER SOUTH...THE ERN EXTENT OF THE CRITICAL AREA OVER CENTRAL TX
   IS WHERE THE WEAKER PRESSURE GRADIENT WILL SUPPORT WEAKER /LESS THAN
   20 MPH/ SUSTAINED WINDS.
   
   ...ERN NM/TX PANHANDLE...
   WEST OF THE CRITICAL AREA...MODERATE TO STRONG SWLY WINDS /20-30
   MPH/ WILL BE PRESENT AHEAD OF AN UPPER TROUGH WHERE MID LEVEL COLD
   ADVECTION WILL INCREASE LOW-MID LEVEL LAPSE RATES. HOWEVER...
   MODERATE AMOUNTS OF CLOUD COVER COMBINED WITH WEAK LOW LEVEL COLD
   ADVECTION /TEMPERATURES IN THE 50S TO LOWER 60S/ WILL LIKELY KEEP
   MIN RH READINGS ABOVE 15 PERCENT. GIVEN THESE EXPECTED CONDITIONS...
   A CRITICAL OUTLOOK AREA WILL NOT BE ISSUED ATTM.
