   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   STORM TRACK WILL REMAIN ALONG THE NRN TIER OF STATES WITH ONE LOW
   AMPLITUDE TROUGH DIPPING SEWD ACROSS THE GREAT LAKES INTO NEW
   ENGLAND...AN ANOTHER OVER SWRN CANADA. IN BETWEEN...A GENERAL UPPER
   RIDGE WILL REMAIN FROM THE SERN CONUS WWD INTO THE ROCKIES.
   
   ...NRN AND NWRN MS AND SRN AR INTO NRN TX...
   IT WILL REMAIN VERY WARM TODAY WITH SWLY WINDS AROUND A WEAKENING
   AREA OF HIGH PRESSURE. LOW LEVEL LAPSE RATES WILL STEEPEN DURING THE
   AFTERNOON WHICH WILL ALLOW FOR INCREASED INSTABILITY. RH LEVELS WILL
   DECREASE INTO THE 30 PERCENT RANGE IN GENERAL...WITH LOCAL VALUES
   INTO THE 20S. WINDS WILL NOT BE STRONG...ONLY AVERAGING NEAR 10 MPH
   OUT OF THE SW. HOWEVER...GIVEN EXTREME ONGOING DROUGHT...A MARGINAL
   FIRE THREAT WILL EXIST.
   
   ...WRN NEB...CNTRL AND WRN SD...
   HIGH PRESSURE WILL SHIFT EWD INTO THE UPPER MS VALLEY
   TODAY...ALLOWING A RETURN SLY FLOW THROUGH THE PLAINS. WINDS WILL
   INCREASE DURING THE AFTERNOON...PEAKING AT 15-20 MPH ACROSS WRN NEB
   INTO SD...WITH HIGHER GUSTS. RH LEVELS WILL BE QUITE LOW RANGING
   FROM NEAR 15 PERCENT SD TO AROUND 20 PERCENT NWRN NEB. THUNDERSTORMS
   WILL BE LIKELY OVER WRN SD NEAR THE BLACK HILLS SWD INTO WRN
   NEB...WHICH WILL MITIGATE FIRE THREAT LATE IN THE DAY.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0503 AM CDT THU AUG 03 2006
   
   VALID 041200Z - 051200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR MUCH OF SD...NWRN NEB...SERN
   ND...FAR NW MN...
   
   ...SYNOPSIS...
   A SURFACE LOW WILL DEEPEN OVER WRN SD DUE TO EFFECTS OF LOW
   AMPLITUDE UPPER TROUGH MOVING EWD ACROSS SRN CANADA. THIS WILL
   STRENGTHEN SURFACE PRESSURE GRADIENT CAUSING STRONG WINDS ACROSS THE
   NRN PLAINS WITH CRITICAL FIRE CONDITIONS. FRONTAL BOUNDARY WILL
   EXTEND ACROSS WRN ND INTO NERN WY FRI AFTERNOON WITH SHIFTING WINDS
   BEHIND IT. ELSEWHERE..SOME MOISTURE WILL MAKE IT NWD INTO ERN ID AND
   SWRN MT WITH SLY FLOW AROUND UPPER HIGH. A FEW THUNDERSTORMS WILL BE
   LIKELY WITH LITTLE RAINFALL AND LIGHTNING STRIKES.
   
   ...CRITICAL FIRE WEATHER AREA - MUCH OF SD...NWRN NEB...SERN
   ND...FAR NW MN...
   
   PRIMARY CONDITIONS: STRONG WINDS....LOW RH...DROUGHT CONDITIONS
   
   WINDS WILL INCREASE QUICKLY ON FRI AS DEEPENING SURFACE LOW
   INTERACTS WITH ZONE OF HIGH PRESSURE TO THE EAST. THE STRONGEST
   WINDS WILL BE OVER CENTRAL SD...WITH WEAKER FLOW FARTHER N.
   SUSTAINED SLY WINDS OF 20-30 MPH APPEAR LIKELY OVER SD WITH HIGHER
   GUSTS...WITH SPEEDS NEAR 20 MPH INTO ND AND NWRN MN. RH LEVELS WILL
   GRADUALLY DECREASE TO 20-25 PERCENT...WITH A FEW AREAS IN CENTRAL SD
   REACHING THE UPPER TEENS. STRONG WINDS WILL EXTEND INTO ERN SD AND
   NEB AS WELL...BUT RECENT RAINFALL WILL MITIGATE THREAT THERE.
   
   FIRE THREAT MAY END ABRUPTLY FROM WRN SD INTO MUCH OF ND AND NRN MN
   DURING THE AFTERNOON...WHERE THERE IS A GOOD CHANCE OF THUNDERSTORMS
   PRODUCING RAIN.
   
   ...ERN MT AND WY...
   IT WILL BE WARM AND DRY WITHIN A POST FRONTAL AIR MASS. WLY WINDS OF
   10-15 MPH ARE LIKELY...ALONG WITH TEMPERATURES IN THE 90S AND RH IN
   THE TEENS. THUS...A MARGINAL FIRE THREAT WILL EXIST GIVEN VERY DRY
   FUEL CONDITIONS.
   
   ...SWRN MT...ERN ID...NWRN WY...
   AT LEAST ISOLATED THUNDERSTORMS ARE LIKELY AS AN AREA OF MOISTURE
   SHIFTS NEWD AROUND UPPER HIGH. SURFACE RH LEVELS ARE EXPECTED TO BE
   AROUND 20-25 PERCENT...WHICH MAY YIELD DECENT EVAPORATION POTENTIAL
   FOR DRY LIGHTNING AND GUSTY WINDS. SURFACE WINDS WILL GENERALLY BE
   OUT OF THE WEST AT 10-15 MPH.
   
   ...NRN TX...
   WARM WEATHER WILL PERSIST ALTHOUGH MOISTURE LEVELS WILL BE UP A BIT
   DUE TO WEAKENING OF SURFACE HIGH TO THE EAST. STILL...SELY WINDS OF
   10-15 MPH MAY INCREASE FIRE DANGER DURING PEAK HEATING HOURS GIVEN
   VERY DRY FUELS.
