   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0341 AM CDT SUN APR 13 2008
   
   VALID 131200Z - 141200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR NRN FLA....SRN GA/SERN AL...
   
   ...SYNOPSIS...
   A DEEP/BROAD UPPER TROUGH WILL REMAIN OVER THE ERN HALF OF THE
   NATION THROUGH THE PERIOD. ASSOCIATED WITH THIS SYSTEM...A COLD
   FRONT WILL MOVE THROUGH FLA AND THE GULF OF MEXICO TODAY.
   MEANWHILE...UPPER RIDGING OVER THE WRN STATES WILL GRADUALLY SHIFT
   EWD. ANOTHER DAY OF WELL ABOVE NORMAL TEMPERATURES IS EXPECTED
   ACROSS MUCH OF THE WEST AS A RESULT OF THE UPPER RIDGE.
   
   ...CRITICAL FIRE WEATHER AREA - NRN FLA...SERN AL/SRN GA...
   
   PRIMARY CONDITIONS: SUSTAINED WNWLY WINDS FROM 15-20 MPH WITH GUSTS
   OVER 25 MPH...MIN RH READINGS FROM 25-35 PERCENT
   
   BEHIND A COLD FRONT...STRONG LOW-MID LEVEL WINDS AND STEEP LAPSE
   RATES FROM THE SFC TO ABOVE 5000 FT AGL WILL SUPPORT MODERATE
   SUSTAINED WLY SFC WINDS TODAY. ALONG WITH THESE WINDS...MUCH DRIER
   AIR WITH DWPTS IN THE 30S COMBINED WITH TEMPERATURES IN THE 60S/70S
   WILL SUPPORT MIN RH READINGS FROM 25-35 PERCENT. DESPITE LIGHT
   PRECIPITATION OVER NRN FL THIS MORNING...RECENT DRY WEATHER OVER THE
   LAST 7 DAYS COMBINED WITH THESE EXPECTED WEATHER CONDITIONS WILL AID
   IN A CRITICAL FIRE WEATHER THREAT. 
   
   FURTHER NORTH...SUSTAINED WNWLY WINDS FROM 15-20 MPH AND LOW RH
   READINGS FROM 25-35 PERCENT WILL BE COMMONPLACE OVER THE REMAINDER
   OF AL/GA AND THE CAROLINAS. HOWEVER...RECENT GREEN-UP AND MODERATE
   TO HEAVY PRECIP IN THIS REGION WILL PRECLUDE ANY CRITICAL FIRE
   WEATHER THREAT.
   
   ...SRN PLAINS...
   IN THE WAKE OF A SECONDARY COLD FRONT THIS MORNING...NWLY WINDS WILL
   AVERAGE FROM 15-20 MPH WITH GUSTS UP TO 25 MPH THIS AFTERNOON FROM
   OKLAHOMA INTO CENTRAL TX. RELATIVELY COOL TEMPERATURES FROM THE
   UPPER 50S IN THE OK TO THE LOWER 70S IN CENTRAL TX WILL COMBINE WITH
   DWPTS IN THE 30S TO PRODUCE MIN RH READINGS FROM 25-30 PERCENT.
   GIVEN MARGINAL WINDS/RH READINGS...A CRITICAL AREA IS NOT FORECAST. 
   
   
   ...SRN AZ...
   IN THE WAKE OF SECONDARY FRONTAL BOUNDARY PASSAGE OF THE SRN ROCKIES
   THIS MORNING HIGH PRESSURE BUILDING SWD THROUGH THE ROCKIES AND WILL
   SUPPORT AN INCREASING E-W ORIENTED PRESSURE GRADIENT. SUSTAINED ELY
   WINDS FROM 15-20 MPH WITH GUSTS OVER 25 MPH WILL BE LIKELY THROUGH
   20Z ACROSS MUCH OF SRN AZ. ALTHOUGH VERY WARM/DRY AIRMASS EXISTS
   OVER THE REGION TODAY...WITH HIGH TEMPERATURES MORE THAN 10 DEG F
   ABOVE NORMAL AND MIN RH READINGS FROM 5-10 PERCENT...THE LACK OF A
   LONGER DURATION OF STRONG WINDS DURING THE PERIOD OF LOWEST RH
   READINGS WILL PRECLUDE AN OUTLOOK AREA.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0344 AM CDT SUN APR 13 2008
   
   VALID 141200Z - 151200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR THE SRN GREAT BASIN AND PORTIONS
   OF THE LOWER CO RIVER VALLEY...
   ...CRITICAL FIRE WEATHER AREA FOR CENTRAL/SRN FLA...
   
   ...SYNOPSIS...
   A STRONG UPPER TROUGH WILL BEGIN TO MOVE INTO THE WRN CONUS
   TOMORROW. ASSOCIATED WITH THIS SYSTEM...AN AREA OF LOW PRESSURE WILL
   DEEPEN OVER THE NRN GREAT BASIN. AHEAD OF AN ASSOCIATED COLD
   FRONT...SWLY WINDS WILL INCREASE OVER MUCH OF THE GREAT BASIN REGION
   LEADING TO CRITICAL FIRE WEATHER CONDITIONS OVER PORTIONS OF THE
   REGION WHERE FUELS ARE SUFFICIENTLY DRY. FURTHER EAST...AN
   INTENSIFYING LEE TROUGH OVER THE HIGH PLAINS AND RETREATING HIGH
   PRESSURE OVER THE MS VALLEY WILL SUPPORT STRENGTHENING SLY WINDS
   OVER MUCH OF THE HIGH PLAINS REGION. OVER PORTIONS OF THE
   NRN/CENTRAL HIGH PLAINS...RH READINGS MAY BECOME SUFFICIENTLY LOW
   ENOUGH TO SUPPORT CRITICAL FIRE WEATHER CONDITIONS. ELSEWHERE...NWLY
   WINDS WILL REMAIN MODERATE OVER MUCH OF THE SERN STATES ASSOCIATED
   WITH A STRONG UPPER TROUGH AND AS SFC HIGH PRESSURE BUILDS INTO THE
   MS VALLEY. HOWEVER...MUCH COOLER THAN NORMAL TEMPERATURES SHOULD
   MINIMIZE ANY CRITICAL FIRE WEATHER POTENTIAL EXCEPT OVER CENTRAL/SRN
   FLA.
   
   ...CRITICAL FIRE WEATHER AREA - SRN NV...SERN CA...SWRN UT AND NWRN
   AZ...
   
   PRIMARY CONDITIONS: SUSTAINED SWLY WINDS FROM 20-25 MPH WITH GUSTS
   OVER 30 MPH...MIN RH READINGS FROM 5-10 PERCENT
   
   AHEAD OF A DEEPENING UPPER TROUGH...AN AREA OF LOW PRESSURE WILL
   INTENSIFY OVER THE NRN GREAT BASIN. STRENGTHENING MID LEVEL WINDS
   COMBINED WITH STEEP LOW-MID LEVEL LAPSE RATES WILL SUPPORT SUSTAINED
   SWLY WINDS FROM 20-25 MPH OVER THE AREA DURING THE AFTERNOON HOURS.
   THE STRONGEST SFC WINDS ARE EXPECTED OVER SRN NV WHERE THE STRONGEST
   MID LEVEL WINDS WILL EXIST DURING THE PERIOD OF MAX HEATING.
   COMBINED WITH A WARM/DRY AIRMASS /NEAR RECORD AFTERNOON HIGH TEMPS
   AND RH READINGS DOWN TO 5 PERCENT/ WILL LEAD TO CRITICAL FIRE
   WEATHER CONDITIONS. TO THE SOUTH OF A COLD FRONT...WINDS WILL REMAIN
   MODERATE IN HIGHER ELEVATIONS OVERNIGHT SUPPORTING POOR RH RECOVERY.
   
   ...CRITICAL FIRE WEATHER AREA - CENTRAL/SRN FLA...
   
   PRIMARY CONDITIONS: SUSTAINED WLY WINDS FROM 15-20 MPH WITH GUSTS UP
   TO 25 MPH...MIN RH READINGS FROM 30-35 PERCENT
   
   IN THE WAKE OF A STRONG COLD FRONT...MODERATE WIND FIELDS COMBINED
   WITH STEEP LOW LEVEL LAPSE RATES WILL SUPPORT STRONG WLY WINDS OVER
   THE FLA PENINSULA TOMORROW. ALTHOUGH TEMPERATURES WILL BE BELOW
   NORMAL /70S/ LOW DEWPTS IN THE 30S/40S WILL SUPPORT MIN RH READINGS
   FROM 30-35 PERCENT. THE COMBINATION OF THESE CONDITIONS WILL SUPPORT
   A CRITICAL FIRE WEATHER THREAT FOR THE AFTERNOON HOURS.
   
   ...NRN/CENTRAL HIGH PLAINS...
   A DEEPENING AREA OF SFC LOW PRESSURE/LEE TROUGH OVER THE NRN ROCKIES
   WILL SUPPORT AN INCREASING PRESSURE GRADIENT OVER THE HIGH PLAINS
   REGION. WELL ABOVE NORMAL TEMPERATURES WILL COMBINE WITH INCREASING
   SUSTAINED SLY WINDS /15-20 MPH/ TO SUPPORT NEAR CRITICAL FIRE
   WEATHER CONDITIONS. ERN MT/WRN ND WILL BE MONITORED FOR POSSIBLE
   UPGRADE IN TOMORROW/S OUTLOOK WHERE FUELS REMAIN THE DRIEST.
   
   ...SRN HIGH PLAINS...
   ALTHOUGH WINDS WILL INCREASE...THE DURATION OF SUSTAINED WINDS ABOVE
   20 MPH APPEARS TO BE LIMITED TO 1-2 HR PERIOD DURING THE MID-LATE
   AFTERNOON. HOWEVER...WARMING TEMPERATURES INTO THE 70S/LOWER 80S
   WILL SUPPORT MIN RH READINGS FROM 10-15 PERCENT AND VERY HIGH FIRE
   DANGER.
