   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   1144 PM CDT SAT APR 23 2005
   
   VALID 241200Z - 251200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SOUTHEAST...
   
   ...SYNOPSIS...
   UNSEASONABLY COOL TEMPERATURES WILL CONTINUE OVER MUCH OF THE ERN
   THIRD OF THE NATION IN ASSOCIATION WITH A BROAD UPPER LOW/TROUGH
   OVER THIS REGION. SFC HIGH PRESSURE WILL CONTINUE TO BUILD SWD
   THROUGH THE SRN PLAINS INTO THE CENTRAL GULF OF MEXICO BY 25/12Z.
   THE COMBINATION OF STRONG MID LEVEL WIND FIELDS AND A MODERATE
   PRESSURE GRADIENT BETWEEN THE SFC HIGH AND LOW PRESSURE OVER THE ERN
   GREAT LAKES WILL LEAD TO BREEZY CONDITIONS ACROSS MUCH OF THE SERN
   STATES/FL. AREAS THAT SAW LITTLE PRECIPITATION IN THE LAST 24
   HRS/WEEK AND WILL SEE LOW RH READINGS COMBINED WITH THE
   AFOREMENTIONED WINDS WILL HAVE A CRITICAL FIRE WEATHER THREAT.
   
   FARTHER WEST...A SRN STREAM UPPER TROUGH WILL MOVE FROM THE SWRN
   STATES INTO THE SRN PLAINS BY THE END OF PERIOD. SCT LGT-MOD
   PRECIPITATION CAN BE EXPECTED OVER MUCH OF THIS REGION. MODERATE
   SWLY WINDS FROM 15-30 MPH CAN BE EXPECTED IN THE WAKE OF THE UPPER
   TROUGH OVER SERN AZ...NM AND FAR WRN TX.
   
   ...CRITICAL FIRE WEATHER AREA 1 - MUCH OF CENTRAL/NRN FL...SERN
   GA...FAR ERN SC...
   
   PRIMARY CONDITIONS: SUSTAINED WINDS FROM 15-25 MPH...MIN RH READINGS
   FROM 25-30 PERCENT...LITTLE SHORT TERM PRECIPITATION
   
   A DEEP SFC LOW WILL MOVE SLOWLY NWD ACROSS THE ERN GREAT LAKES
   DURING THE PERIOD. AN ASSOCIATED COLD FRONT WILL CONTINUE TO PUSH
   SWD THROUGH FL OVERNIGHT...AND SHOULD CLEAR THE SRN PART OF THE
   STATE AROUND 24/18Z. BEHIND THIS FRONT...SFC HIGH PRESSURE WILL
   BUILD SWD INTO THE GULF OF MEXICO DURING THE PERIOD. ACCOMPANYING 
   DRY AIR WITH DEWPTS IN THE 20S/30S WILL CONTINUE TO FILTER SWD
   THROUGH THE SERN STATES/FL DURING THE PERIOD. THE COMBINATION OF A
   MODERATE PRESSURE GRADIENT AND STRONG MID LEVEL WIND MAX MOVING
   THROUGH THE REGION DURING THE AFTERNOON HOURS WILL SUPPORT WNW WINDS
   FROM 15-30 MPH ACROSS THE CRITICAL OUTLOOK AREA. DESPITE COOL
   TEMPERATURES IN THE 60S TO LOWER 70S...MIN RH READINGS WILL AVERAGE
   FROM 25-30 PERCENT GIVEN DEWPTS IN THE 20S/30S. SINCE THIS AREA HAS
   SEEN ONLY SCT PRECIPITATION IN THE LAST 24 HOURS...AND A RECENT DRY
   SPELL...THE ABOVE CONDITIONS WARRANT A CRITICAL FIRE WEATHER THREAT.
   
   ...REMAINDER OF THE SERN STATES...
   MODERATE WINDS AND LOW RH READINGS WILL OCCUR OVER MOST OF THE
   REMAINDER OF THE SERN STATES TODAY. DESPITE SUSTAINED WINDS FROM
   15-25 MPH OVER THIS REGION...A COMBINATION OF SEVERAL FACTORS WILL
   LIMIT THE CRITICAL FIRE WEATHER THREAT TODAY. MUCH OF GA/AL HAVE
   SEEN MOD TO HVY PRECIP IN THE LAST 24-30 HOURS. IN ADDITION
   TEMPERATURES OVER THIS AREA WILL BE MUCH BELOW NORMAL...WITH
   READINGS MAINLY IN THE 50S. THUS MIN RH READINGS ARE GOING TO BE
   BORDERLINE CRITICAL /AROUND 30 PERCENT/. IN ADDITION...AREAS THAT
   RECEIVED APPRECIABLE RAINFALL...SRN AL/GA IN THE LAST 24 HOURS WILL
   SEE LIMITED EVAPORATION POTENTIAL GIVEN THE COOL TEMPERATURES.
   FURTHER EAST OVER MOST OF THE CAROLINAS... TEMPERATURES ARE FCST TO
   REMAIN IN THE 50S AS WELL. COMBINED WITH DEWPTS IN THE
   20S/30S...THIS WILL LEAD TO MIN RH READINGS FROM 30-35 PERCENT OR
   SLIGHTLY ABOVE CRITICAL LEVELS.
   
   ...SERN AZ...SRN NM/FAR WRN TX...
   SCT LGT-MOD PRECIPITATION WILL SPREAD OVER MUCH OF THIS REGION EARLY
   IN THE PERIOD. MODERATE SWLY WINDS FROM 15-30 MPH WILL OCCUR IN THE
   WAKE OF THE UPPER TROUGH OVER MUCH OF ERN AZ...NM AND FAR WRN TX
   DURING THE AFTERNOON HOURS. HOWEVER...LOW LEVEL COOLING IN THE WAKE
   OF A COLD FRONTAL PASSAGE ACROSS NM/WRN TX YESTERDAY AND LIGHT/MOD
   PRECIPITATION OVER SERN AZ WILL LEAD TO MIN RH READINGS GENERALLY
   ABOVE 20 PERCENT AREA WIDE.  ISO-SCT HIGH BASED/MAINLY DRY
   CONVECTION CAN BE EXPECTED OVER SWRN NM/FAR WRN TX DURING THE
   AFTERNOON/EVENING HOURS AS A DEEPLY MIXED ENVIRONMENT EXISTS BENEATH
   STEEP MID LEVEL LAPSE RATES.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0105 AM CDT SUN APR 24 2005
   
   VALID 251200Z - 261200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SWRN TX/SERN NM...
   
   ...SYNOPSIS...
   A BROAD UPPER LOW/TROUGH CENTERED OVER THE ERN SEABOARD/NEW ENGLAND
   AT THE START OF DAY 2...WILL GRADUALLY SHIFT ENEWD INTO SERN CANADA
   THROUGH THE PERIOD. FARTHER WEST...ADDITIONAL UPPER LEVEL SHORTWAVE
   TROUGHS WILL DIG SWD FROM SCENTRAL CANADA INTO THE PLAINS STATES.
   MEANWHILE...A SRN STREAM UPPER TROUGH WILL MOVE FROM SRN PLAINS INTO
   THE SE. MODERATE WINDS WILL ACCOMPANY THE SRN STREAM SYSTEM.
   
   MIN RH READINGS WILL AGAIN DROP TO AOB 30 PERCENT ACROSS MUCH OF THE
   SERN STATES. WINDS WILL AVG AROUND 10 MPH ACROSS MOST OF
   FL/GA/AL...WITH STRONGER SUSTAINED WINDS AROUND 15 MPH ACROSS THE
   CAROLINAS INTO VA. MARGINAL WIND SPEEDS WILL PRECLUDE A CRITICAL
   FIRE WEATHER THREAT.
   
   ...CRITICAL FIRE WEATHER AREA 1 - SWRN TX/SERN NM...
   
   PRIMARY CONDITIONS: SUSTAINED WINDS FROM 20-30 MPH WITH GUSTS OVER
   40 MPH...MIN RH VALUES AROUND 15 PERCENT
   
   STEEP LOW-MID LEVEL LAPSE RATES BENEATH MID LEVEL SPEED MAX WILL AID
   IN MOMENTUM TRANSFER OF STRONGER FLOW ALOFT. SUSTAINED SFC WINDS
   FROM 20-30 MPH WITH HIGHER GUSTS IN THE DAVIS/GUADALUPE MTNS WILL BE
   A RESULT ESPECIALLY DURING THE LATE MORNING/AFTERNOON HOURS.
   THE DRYLINE IS FCST TO DEVELOP EWD AND EXTEND FROM A SFC LOW OVER OK
   SWD INTO CENTRAL TX BY 26/00Z. TO THE WEST OF THE DRYLINE...WARM
   TEMPERATURES IN THE 80S AND DEWPTS IN THE 20S/30S WILL LEAD TO MIN
   RH READINGS AROUND 15 PERCENT.
   
   ...CAROLINAS/VA...
   SWLY WINDS AROUND 15 MPH CAN BE EXPECTED DURING THE AFTERNOON HOURS.
   TEMPERATURES WILL BE SOMEWHAT WARMER THAN ON DAY ONE...WITH READINGS
   IN THE 60S. LOW DEWPTS IN THE 20S/30S WILL LEAD TO MIN RH READINGS
   FROM 25-30 PERCENT.
