   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0210 AM CDT FRI APR 25 2008
   
   VALID 251200Z - 261200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A STRONG SURFACE LOW WILL MOVE NEWD ACROSS THE UPPER MS VALLEY WITH
   A COLD FRONT TRAILING SWWD INTO MO/AR AND CNTRL TX BY AFTERNOON.
   BEHIND THIS FRONT...HIGH PRESSURE WILL BUILD SWD THROUGH THE PLAINS
   PROVIDING COOLER BUT STILL VERY DRY CONDITIONS WITH NWLY WINDS. TO
   THE W...UPPER RIDGING WILL COMMENCE AS THE CNTRL U.S. TROUGH LIFTS
   OUT...AND HIGH PRESSURE OVER THE GREAT BASIN WILL PROVIDE VERY DRY
   CONDITIONS TO ALL OF THE SWRN STATES. ELSEWHERE...HIGH PRESSURE OVER
   THE ATLANTIC COAST WILL KEEP CONDITIONS RELATIVELY DRY AND MILD OVER
   THE SERN STATES.
   
   ...ERN CO...WRN KS...MUCH OF NEW MEXICO AND W TX...
   A COLD FRONT WILL CONTINUE SWD INTO TX TODAY WITH GUSTY NLY WINDS
   BEHIND IT. THE STRONGEST WINDS WILL BE OVER KS AND OK...WITH SPEEDS
   OF 20-25 MPH AND HIGHER GUSTS. IN THOSE AREAS...THE COMBINATION OF
   RECENT PRECIPITATION ALONG WITH MARGINAL MIN RH VALUES IN THE 20
   PERCENT RANGE WILL MITIGATE THE OVERALL THREAT. FARTHER S AND W INTO
   NM AND W TX...IT WILL BE MUCH DRIER...WITH RH INTO THE TEENS AND
   SINGLE DIGITS S. THIS WILL KEEP THE THREAT OF FIRE STARTS HIGH...BUT
   SUSTAINED WIND SPEEDS ARE EXPECTED TO REMAIN BELOW CRITICAL
   CRITERIA...ESPECIALLY BY AFTERNOON WHEN SPEEDS DECREASE TO NEAR 15
   MPH. STILL...THE EXTREME DRYNESS AND WIND GUSTS ESPECIALLY OVER NM
   MAY RESULT IN MARGINAL CRITICAL CONDITIONS.
   
   ...SRN CA INTO AZ...
   AN EXTREMELY DRY AIR MASS WILL REMAIN IN PLACE TODAY...HELPED BY THE
   PRESENCE OF HIGH PRESSURE TO THE N. MIN RH VALUES WILL LARGELY DIP
   INTO THE MIDDLE SINGLE DIGITS...WITH VERY STEEP LOW TO MID LEVEL
   LAPSE RATES/HIGH HAINES INDEX. LOCALLY GUSTY N WINDS WILL OCCUR BOTH
   NEAR THE COASTAL RANGE IN SRN CA AND INTO THE LOWER CO RIVER
   VALLEY...BUT SPEEDS ARE EXPECTED TO REMAIN SUB CRITICAL.
   STILL...FUELS CONTINUE TO DRY AND THE EXTREMELY LOW RH LEVELS WILL
   ELEVATE THE THREAT OF FIRES.
   
   ...SERN STATES...
   SELY WIND TRAJECTORIES OFF THE ATLANTIC YET OUT OF A SURFACE HIGH
   COMBINED WITH DAYTIME HEATING SHOULD ALLOW AREAS OF MIN RH NEAR 35
   PERCENT FOR A COUPLE HOURS THIS AFTERNOON. THE MARGINALLY LOW RH AND
   WINDS TO 10-15 MPH MAY YIELD A SHORT DURATION FIRE THREAT
   ENHANCEMENT WHERE FUELS REMAIN LOCALLY DRY.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0228 AM CDT FRI APR 25 2008
   
   VALID 261200Z - 271200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR MUCH OF NRN AND NERN NM...WRN
   OK/TX PANHANDLES...
   
   ...SYNOPSIS...
   A BROAD UPPER TROUGH WILL COVER MUCH OF THE CENTRAL PART OF THE
   CONUS...WITH A LEAD UPPER SHORTWAVE EJECTING NEWD ACROSS THE GREAT
   LAKES...AND ANOTHER DIGGING TROUGH EMERGING INTO THE CNTRL/SRN HIGH
   PLAINS. THIS SECONDARY TROUGH WILL CREATE WINDY CONDITIONS FOR NM
   AND W TX...WHERE RH REMAINS LOW. LATE IN THE DAY AND OVERNIGHT...A
   STRONG COLD FRONT WILL BRING SHIFTING WINDS TO THE SAME AREAS.
   
   TO THE W...AN UPPER RIDGE AXIS WILL BE SITUATED OVER THE W
   COAST...WITH HIGH PRESSURE ACROSS THE GREAT BASIN AND CNTRL/NRN
   ROCKIES. AS A RESULT...VERY DRY AND WARM WEATHER WILL CONTINUE FOR
   SRN CA INTO AZ...WITH LOCALLY GUSTY N WINDS.
   
   ...CRITICAL FIRE WEATHER AREA - MUCH OF NRN AND NERN NM...WRN OK/TX
   PANHANDLES...
   
   PRIMARY CONDITIONS: STRONG WINDS...LOW RH...WIND SHIFT WITH COLD
   FRONT
   
   TEMPERATURES WILL GRADUALLY WARM INTO THE 60S AND 70S AFTER A COOL
   START TO THE DAY...WHILE NWLY WINDS PICK UP IN ADVANCE OF AN
   APPROACHING UPPER TROUGH. MIN RH WILL DROP EASILY INTO THE LOWER
   TEENS...WHILE SUSTAINED NWLY WINDS INCREASE TO AROUND 20 MPH WITH
   HIGHER GUSTS ESPECIALLY ALONG THE LEEWARD MTN SLOPES IN NM. SOME
   LOCATIONS COULD SEE RH INTO THE UPPER SINGLE DIGITS.
   
   LATE IN THE DAY...A COLD FRONT WILL SURGE SWD OUT OF CO AND
   KS...SHIFTING WINDS TO NLY AND INCREASING THEM TO 20-30 MPH WITH
   HIGHER GUSTS. RH RECOVERY SHOULD REMAIN RATHER POOR THROUGH THE
   EVENING...THUS...ANY ONGOING FIRES COULD EXPERIENCE A RAPID CHANGE
   IN DIRECTION WITH THE FRONT. THIS FRONT WILL MAKE IT TO THE MEXICO
   BORDER BY SUN MORNING.
   
   ...SRN CA INTO AZ...
   IT WILL BE QUITE WARM INLAND AS UPPER RIDGE BUILDS...WHILE NLY WINDS
   OUT OF THE GREAT BASIN HIGH KEEP RH IN THE SINGLE DIGITS AND TEENS.
   PASSES AND CANYON AREAS NEAR THE COASTAL RANGE WILL SEE LOCALIZED
   WIND GUSTS...AS WILL AREAS THROUGH THE CO RIVER VALLEY. ALTHOUGH
   VERY DRY...THE WINDS ARE NOT EXPECTED TO REACH CRITICAL CRITERIA.
