   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0336 AM CDT THU APR 24 2008
   
   VALID 241200Z - 251200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR ERN AZ...NM...SWRN TX...EXTREME
   SWRN OK...OK/TX PANHANDLES...SERN CO...
   ...CRITICAL FIRE WEATHER AREA FOR LOWER MI...
   ...CRITICAL FIRE WEATHER AREA FOR MUCH OF NEW ENGLAND AND ERN NY...
   
   ...SYNOPSIS...
   AN UPPER TROUGH AXIS WILL MOVE INTO THE NRN ROCKIES BY
   AFTERNOON...CAUSING LOW PRESSURE TO DEEPEN OVER ERN CO AND WRN KS. A
   STRONG PRESSURE GRADIENT ACROSS THE SRN PLAINS/ROCKIES WILL RESULT
   IN STRONG WINDS..AND WILL BRING WARM AND DRY AIR NWD.
   
   TO THE E...AN UPPER RIDGE WILL EXIST WITH AN EXPANSIVE AREA OF HIGH
   PRESSURE FROM THE GREAT LAKES INTO NEW ENGLAND SWD INTO THE MID
   ATLANTIC. WIDESPREAD DRY CONDITIONS WILL RESULT. GUSTY WINDS BEHIND
   A COLD FRONT WILL RESULT IN CRITICAL FIRE CONDITIONS FOR PORTIONS OF
   NEW ENGLAND WHILE STRONG SLY WINDS IN ADVANCE OF THE PLAINS LOW
   CAUSES HAZARDOUS FIRE CONDITIONS OVER LOWER MI.
   
   ...CRITICAL FIRE WEATHER AREA - ERN AZ...NM...SWRN TX...EXTREME SWRN
   OK...OK/TX PANHANDLES...SERN CO...
   
   PRIMARY CONDITIONS: STRONG WINDS AND VERY LOW RH
   
   AS THE BASE OF THE UPPER TROUGH MOVES OVERHEAD...WINDS WILL INCREASE
   TO 20-30 MPH OUT OF THE WEST WITH HIGHER GUSTS. A VERY DRY AIR MASS
   IS ALREADY IN PLACE...AND STRONG MIXING WILL RESULT IN MIN RH
   READINGS IN THE SINGLE DIGITS AND LOWER TEENS. THE COMBINATION OF
   STRONG WINDS AND LOW RH...COMBINED WITH VERY DRY FUELS WILL RESULT
   IN POTENTIALLY DANGEROUS FIRE BEHAVIOR THIS AFTERNOON. IN
   ADDITION...ALTHOUGH WINDS WILL DECREASE OVERNIGHT...RH RECOVERY WILL
   VERY QUITE POOR...SUGGESTING THE FIRE THREAT COULD CONTINUE.
   
   SOME AREAS OF FAR ERN NM AND WRN TX RECEIVED SUBSTANTIAL RAINFALL ON
   WED...AND THOSE AREAS HAVE BEEN CUT OUT OF THE CRITICAL AREA. PLEASE
   SEE GRAPHIC FOR MORE DETAIL.
   
   ...CRITICAL FIRE WEATHER AREA - LOWER MI...
   
   PRIMARY CONDITIONS: STRONG WINDS AND LOW RH
   
   A HIGH PRESSURE CENTER WILL SHIFT JUST E OF THE AREA TODAY...WHILE
   LOW PRESSURE DEEPENS TO THE W. THIS WILL INCREASE THE PRESSURE
   GRADIENT AND WINDS...WITH 15-20 MPH SELY WINDS LIKELY. MIN RH VALUES
   WILL LARGELY BE IN THE 20 PERCENT RANGE AS TEMPERATURES RISE INTO
   THE 70S. ALTHOUGH KBDI VALUES ARE NOT HIGH...RECENT DRYNESS HAS
   CONTRIBUTED TO AREAS OF DRYING FUELS AND THUS A FIRE THREAT GIVEN
   THE WIND/RH COMBINATION.
   
   ...CRITICAL FIRE WEATHER AREA - MUCH OF NEW ENGLAND AND ERN NY...
   
   PRIMARY CONDITIONS: GUSTY WINDS AND LOW RH
   
   IN A POST FRONTAL REGIME...NWLY WINDS OF 15-20 MPH ARE LIKELY. SOME
   SHOWERS OCCURRED WITH THURSDAYS COLD FRONT PASSAGE...BUT OVERALL QPF
   AMOUNTS WERE LOW. SUNSHINE...TEMPERATURES IN THE 60S TO 70S AND MIN
   RH IN THE 20 PERCENT RANGE SUGGEST A CRITICAL FIRE THREAT FOR AREAS
   WHERE FUELS ARE DRIEST. WINDS WILL DECREASE BY EARLY EVENING WITH
   COOL OVERNIGHT TEMPERATURES.
   
   ...PORTIONS OF WRN TX...
   VERY WARM...WINDY AND DRY CONDITIONS WILL PREVAIL OVER ALL OF WRN TX
   TODAY AS LOW PRESSURE DEEPENS TO THE N. HIGH TEMPERATURES IN THE
   80-90 RANGE ALONG WITH MIN RH IN THE TEENS WILL OCCUR. SWLY WINDS
   WILL INCREASE TO 20-25 MPH WITH HIGHER GUST. THE MITIGATING FACTOR
   TO A CRITICAL THREAT IS THE RECENT PRECIPITATION...SOME OF WHICH WAS
   QUITE HEAVY. AREAS INCLUDING THE HILL COUNTRY DID NOT HAVE MUCH
   PRECIPITATION...HOWEVER...RH VALUES WILL NOT BE AS LOW HERE...MAINLY
   HOLDING ABOVE 30-40 PERCENT.
   
   ...SERN STATES...
   PRESENCE OF HIGH PRESSURE TO THE E WILL MAINTAIN RELATIVELY DRY
   WEATHER CONDITIONS...WITH HIGHS IN THE 70S AND 80S AND MODERATELY
   LOW RH VALUES OF 30-40 PERCENT. AN ELY WIND NEAR 15 MPH WILL
   BLOW...AND MAY CONTRIBUTE TO AN ELEVATED FIRE THREAT ESPECIALLY
   INLAND WHERE IT IS POSSIBLE THAT RH COULD DROP INTO THE 30 PERCENT
   RANGE FOR A FEW HOURS. GIVEN THIS AND ONLY MARGINAL KBDI VALUES...A
   LARGE SCALE CRITICAL THREAT IS NOT EXPECTED.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0430 AM CDT THU APR 24 2008
   
   VALID 251200Z - 261200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER TROUGH WILL CONTINUE TO MOVE EWD FROM THE NRN PLAINS INTO
   THE UPPER MS VALLEY/MIDWEST...WITH SURFACE LOW OVER NRN WI AT 00Z. A
   COLD FRONT WILL TRAIL SWD ACROSS IL INTO AR AND S CNTRL TX...WITH
   COOL BUT DRY AIR ACROSS THE CNTRL PLAINS WITH HIGH PRESSURE. ANOTHER
   AREA OF HIGH PRESSURE WILL EXTEND FROM THE GREAT BASIN ACROSS THE
   ROCKIES...AND WILL HELP TO PRODUCE EXTREMELY DRY WEATHER FOR ALL OF
   THE SWRN STATES. TO THE E...A LARGE AREA OF HIGH PRESSURE OVER THE
   WRN ATLANTIC WILL CONTINUE TO AFFECT THE SERN STATES WITH MILD BUT
   DRY WEATHER.
   
   ...ERN NM INTO WRN TX...
   A COLD FRONT WILL EXTEND FROM CNTRL OK INTO SWRN TX FRI
   MORNING...AND WILL SURGE SWD DURING THE DAY. NLY WIND OF 15-20 MPH
   ARE EXPECTED...BUT TEMPERATURES WILL BE A BIT COOLER. BY LATE
   AFTERNOON...WINDS WILL LIKELY DIE DOWN TO 10-15 MPH...BUT RH WILL BE
   LOWER AND NEAR 15 PERCENT AT PEAK HEATING WHEN TEMPERATURES REACH
   THE 70S. THIS SHOULD RESULT IN A NEAR CRITICAL FIRE THREAT GIVEN THE
   COOLER TEMPERATURES AND MODERATE WINDS.
   
   ...SRN CA INTO AZ...
   LOCALLY GUSTY OFFSHORE WINDS WILL BE ONGOING FRI MORNING OVER SRN
   CA...DUE TO HIGH PRESSURE TO THE N. THE AIR MASS WILL BE VERY DRY
   AND MIN RH WILL BE IN THE SINGLE DIGITS IN MANY AREAS BY AFTERNOON.
   WINDS WILL RELAX SOMEWHAT DURING THE DAY BUT THE EXTREME DRYNESS AS
   WELL AS A HIGH HAINES INDEX WILL KEEP THE FIRE THREAT ELEVATED.
   OVERNIGHT...LOCALLY GUSTY NLY WINDS MAY OCCUR NEAR THE COASTAL
   RANGE...BUT SPEEDS ARE NOT EXPECTED TO REACH CRITICAL INTENSITIES.
   
   ...SERN STATES...
   IT WILL REMAIN WARM AND RELATIVELY DRY DURING THE AFTERNOON AS HIGH
   PRESSURE CONTINUES TO KEEP RH DOWN. MIN VALUES WILL REACH THE 30
   PERCENT RANGE MAINLY ACROSS THE CAROLINAS AND GA...AS WELL AS THE FL
   PANHANDLE.
