   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0148 AM CDT FRI APR 11 2008
   
   VALID 111200Z - 121200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   STRONG UPPER TROUGH WILL BE CENTERED NEAR THE GREAT LAKES AND
   EXTENDING BACK THROUGH NM...WHILE THE MAIN SURFACE LOW WILL BE
   MOVING INTO THE ERN GREAT LAKES REGION BY THE END OF THE PERIOD.
   WIDESPREAD INCLEMENT WEATHER WILL CONTINUE TO AFFECT MUCH OF THE
   EASTERN CONUS AHEAD OF THE SYSTEM...WHILE STRONG WINDS WILL IMPACT
   MUCH OF THE NRN PLAINS AND NORTHEASTERN GREAT LAKES REGION FOLLOWING
   THE LOW.  
     
   MEANWHILE IN THE WEST...HIGH PRESSURE WILL BUILD SSEWD INTO THE
   ROCKIES...WITH NWLY TO NLY FLOW AND MUCH WARMER TEMPERATURES
   DEVELOPING ACROSS THE WRN CONUS AS AMPLIFIED UPPER HIGH PRESSURE AND
   SUBSIDENCE BUILDS IN AS WELL. DRY CONDITIONS WILL PERSIST ACROSS THE
   SWRN STATES.
   
   ...LOWER CO RIVER VALLEY...
   NLY FLOW WILL CONTINUE ACROSS SRN NV AND THE CA/AZ BORDERS...WITH
   CHANNELING THROUGH THE LOWER CO RIVER VALLEY GIVING THE POTENTIAL
   FOR ANOTHER DAY OF SUSTAINED SURFACE WINDS NEAR CRITICAL THRESHOLDS.
   DRY CONDITIONS AND WARMING TEMPERATURES WILL ALLOW RELATIVE
   HUMIDITIES TO DROP INTO THE SINGLE DIGITS AT LOWEST ELEVATIONS.
   GIVEN THAT THE MAIN UPPER JET SUPPORT WILL HAVE MOVED WELL
   EWD...POTENTIAL FOR MIXING OF STRONGER WIND SPEEDS SHOULD BE
   REDUCED. 
     
   ...SRN AZ/NM...WRN TX...
   A NARROW WINDOW OF CRITICAL CONDITIONS MAY BE POSSIBLE DURING THE
   AFTERNOON AND EARLY EVENING. TEMPERATURES WILL REACH INTO THE 60S
   AND 70S WITH RELATIVE HUMIDITIES IN THE SINGLE DIGITS ONCE AGAIN.
   SUSTAINED WIND SPEEDS OF NEAR 20 MPH MAY BE POSSIBLE INITIALLY
   DURING THE AFTERNOON...BEFORE THE SURFACE LOW IN THE GREAT LAKES
   REGION MOVES EWD AHEAD OF A DEVELOPING HIGH PRESSURE REGION IN THE
   PACIFIC NORTHWEST. HIGHER SPEEDS NEAR 25 MPH MAY BE POSSIBLE NEAR
   THE GUADALUPE MOUNTAINS WITH CHANNELING INCREASING SPEEDS LOCALLY.
   ONCE THE SURFACE LOW MOVES EWD...A RELAXATION IN THE SURFACE
   PRESSURE GRADIENT BETWEEN THE TWO SYSTEMS WILL GENERALLY DECREASE
   WINDS ACROSS SRN AZ/NM AND WRN TX. WINDS WILL SHIFT BY EVENING TO
   NWLY THEN NLY INTO THE MORNING AS HIGH PRESSURE BUILDS INTO THE
   WEST. STRONGER MID/UPPER LEVEL WINDS WILL QUICKLY MOVE EWD AS
   WELL...REDUCING THE POTENTIAL FOR STRONGER WINDS TO MIX TO THE
   SURFACE. 
     
   ...SSWRN TX...
   A DRY NLY TO NELY FLOW AND TEMPERATURES WELL INTO THE 80S...AND
   POSSIBLY LOWER 90S...WILL LEAD TO RELATIVE HUMIDITIES IN THE SINGLE
   DIGITS AND LOWER TEENS ACROSS AN AREA THAT HAS BEEN CRITICALLY DRY
   FOR AN EXTENDED TIME FRAME. DESPITE RELATIVELY WEAK WINDS...AN
   ELEVATED FIRE RISK WILL EXIST.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0205 AM CDT FRI APR 11 2008
   
   VALID 121200Z - 131200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A LONG WAVE TROUGH AND COOLER TEMPERATURES WILL DOMINATE IN THE
   EAST. A SURFACE LOW WILL BE EXITING IN NEW ENGLAND WITH A COLD FRONT
   EXTENDING THROUGH THE COAST AND OUT INTO THE GULF WATERS. DRY
   CONDITIONS WILL SLOWLY SETTLE INTO THE SOUTHEAST FOLLOWING A SECOND
   BUT DRIER COLD FRONT...ALTHOUGH VERY COOL TEMPERATURES AND PREVIOUS
   RAINFALL WILL INITIALLY LIMIT FIRE CONCERNS. 
   
   IN THE WEST HIGH PRESSURE AND WARMING TEMPERATURES WILL BUILD
   IN...WHILE A LOW PRESSURE CENTER WILL SLOWLY APPROACH THE
   NORTHWESTERN COAST.
   
   ...SRN PLAINS NEAR THE TX/OK PANHANDLES...
   THE PRESSURE GRADIENT BETWEEN EXITING LOW PRESSURE IN THE NORTHEAST
   AND HIGH PRESSURE BUILDING INTO THE WEST WILL KEEP STRONG NNWLY
   WINDS OVER MUCH OF THE PLAINS. THE RELATIVE HUMIDITY FORECAST WILL
   DEPEND ON HOW MUCH WARMING CAN TAKE PLACE WITHIN THE COOL
   FLOW...ALTHOUGH CURRENT FORECASTS DEPICT TEMPERATURES REACHING INTO
   THE 50S AND POSSIBLY 60S...WHICH WOULD ALLOW RELATIVE HUMIDITIES TO
   DROP INTO THE LOWER 20S IN AFTERNOON MIXING. WITH MIXING...HIGHER
   WIND GUSTS WILL BE POSSIBLE AS WELL...AS STRONGER MID LEVEL WINDS
   INCREASE AROUND THE BACKSIDE OF THE TROUGH.
