   VALID 021200Z - 031200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   UPPER HIGH WILL REMAIN ACROSS THE MUCH OF THE SERN CONUS CENTERED
   OVER THE TN VALLEY...BUT AFFECTING MUCH OF THE AREA FROM THE SRN
   PLAINS NEWD INTO THE OH VALLEY AND SRN NEW ENGLAND WITH HOT
   TEMPERATURES.  CLOCKWISE FLOW AROUND THE SURFACE HIGH OVER MUCH THE
   SAME AREA WILL INDUCE MDT SLY AND SWLY WINDS...WITH MARGINALLY LOW
   RH VALUES ACROSS THE SRN PLAINS WHERE DROUGHT PERSISTS.
   
   ELSEWHERE...A WEAK TO MDT ZONAL FLOW REGIME WILL PERSIST ACROSS THE
   NRN STATES...WITH A PROGRESSIVE SHORTWAVE TROUGH BRINGING STORMS
   ACROSS THE GREAT LAKES INTO NEW ENGLAND. THE ZONAL FLOW WILL ALLOW
   FOR DRY WLY FLOW ACROSS MT INTO THE WRN DAKOTAS. ISOLATED DRY
   THUNDER IS POSSIBLE OVER ERN NV...WITH OTHERWISE WARM AND DRY
   CONDITIONS PERSISTING OVER THE GREAT BASIN INTO CA.
   
   ...OK INTO N TX...
   NEAR CRITICAL FIRE CONDITIONS WILL EXIST TODAY SOUTH OF A WEAK
   SURFACE FRONT WHICH WILL EXTEND FROM THE KS TURNPIKE SWWD INTO NWRN
   OK. VERY WARM...MODERATELY DRY...AND LOCALLY BREEZY CONDITIONS WILL
   CONTINUE WITH SUSTAINED WIND SPEEDS AROUND 15 MPH...WITH SOME AREAS
   GUSTING TO 20 MPH AT TIMES. WINDS OF 10-15 MPH WILL EXTEND SWD INTO
   CENTRAL AND NRN TX...WHERE EXTREME DROUGHT CONDITIONS PERSIST. RH
   LEVELS WILL NOT BE PARTICULARLY LOW...BUT WILL LIKELY DIP INTO THE
   20-30 PERCENT RANGE MAINLY ALONG AND W OF I-35. 
   
   ...ERN MT INTO WRN DAKOTAS...
   SURFACE PRESSURE GRADIENT WILL BE RELATIVELY WEAK TODAY BUT WLY
   ZONAL FLOW ALOFT AND HEATING WILL ALLOW FOR A FEW STRONGER WIND
   GUSTS TO AROUND 15 MPH BY AFTERNOON. RH WILL DIP INTO THE 15-20
   PERCENT RANGE WITH MODERATELY WARM TEMPERATURES IN THE 80S F.

   DAY 2 FIRE WEATHER OUTLOOK CORR 1
   NWS STORM PREDICTION CENTER NORMAN OK
   0519 AM CDT WED AUG 02 2006
   
   VALID 031200Z - 041200Z
   
   CORRECTED FOR GRAPHICAL ERROR
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   OVERALL PATTERN WILL CHANGE LITTLE FROM DAY ONE. A SLIGHT
   STRENGTHENING IN THE UPPER RIDGE WILL OCCUR OVER THE WRN CONUS WITH
   WARMING TEMPERATURES AND MDT TO HIGH HAINES INDEX IN MANY AREAS. AN
   AREA OF MOISTURE WILL SHIFT NWD ACROSS THE GREAT BASIN INTO NRN UT
   AND SRN ID WITH A CHANCE OF AN ISOLATED LIGHTNING STRIKE THERE.
   
   TO THE EAST...A FRONTAL BOUNDARY WILL STRETCH FROM THE OH VALLEY
   SWWD INTO SRN OK/NRN TX...WITH INCREASED RH LEVELS N OF THIS
   BOUNDARY. S OF THE BOUNDARY INTO N TX...IT WILL REMAIN QUITE WARM
   BUT WITH WEAKER WINDS AS LOWER MS VALLEY SURFACE HIGH WEAKENS A BIT.
   RH LEVELS WILL DROP ACROSS SRN AR INTO NWRN MS WITH VEERING SURFACE
   WINDS DUE TO PASSAGE OF WEAK UPPER TROUGH TO THE NORTH.
   
   FARTHER N...HIGH PRESSURE WILL SHIFT EWD OUT OF THE NRN PLAINS AND
   INTO THE UPPER MS VALLEY...ALLOWING A RETURN OF SELY WINDS ACROSS
   WRN SD/NEB.
   
   ...NRN TX EWD INTO SRN AR AND NWRN MS...
   DROUGHT CONDITIONS PERSIST OVER THE ENTIRE AREA...IN PARTICULAR OVER
   NRN TX AND NWRN MS/SERN AR WHERE VERY LITTLE RAIN HAS FALLEN
   RECENTLY. THE HOT AND FAIRLY DRY AIR MASS OVER THE SRN PLAINS WILL
   SHIFT NEWD DUE TO VEERING LOW LEVEL WINDS...WHICH WILL INCREASE
   MIXING HEIGHTS/LOWER ATMOSPHERIC INSTABILITY AND DECREASE RH LEVELS
   DURING THE AFTERNOON HOURS AS STRONG HEATING AND MIXING OCCURS. RH
   LEVELS ACROSS NRN MS AND SRN AR WILL LIKELY BE LOWER THAN
   FORECAST...WITH VALUES DIPPING BELOW 30 PERCENT WHILE SWLY WINDS
   BLOW AT AROUND 10 MPH.
   
   ...WRN OREGON...
   DIURNAL INCREASE IN PRESSURE GRADIENT WILL CAUSE NLY WINDS TO
   DEVELOP W OF THE CASCADES WITH SPEEDS OF 15-20 MPH. RH WILL DROP
   BELOW 30 PERCENT AT PEAK HEATING. MIXING HEIGHTS WILL NOT BE
   PARTICULARLY DEEP THOUGH DUE TO MODIFIED-MARINE NATURE OF AIR MASS.
