   VALID 031200Z - 041200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   MORNING SURFACE ANALYSIS SHOWS AN EXPANSIVE AREA OF HIGH PRESSURE
   BECOMING ESTABLISHED ACROSS MUCH OF THE GREAT PLAINS IN THE WAKE OF
   A SHORTWAVE TROUGH MOVING E OVER THE GREAT LAKES. A SURFACE FRONT
   LOCATED SOUTH OF THE HIGH IS FORECAST TO BECOME POSITIONED FROM THE
   DELMARVA AREA WSW INTO THE LWR MS VALLEY AND SRN TX...WHICH WILL
   SERVE TO FOCUS THUNDERSTORM DEVELOPMENT. FARTHER W...AFTERNOON
   THUNDERSTORM DEVELOPMENT IS BEGINNING TO SHIFT N...ALLOWING STRONG
   LOW LEVEL HEATING TO OCCUR FROM THE DESERT SW NWD INTO THE GREAT
   BASIN. MEANWHILE...AN UPPER LOW WILL REMAIN POSITIONED OFF THE COAST
   OF CA...WITH A STRONG UPPER DISTURBANCE FORECAST TO EJECT ENE FROM
   THE LOW INTO THE GREAT BASIN BY THE END OF THE DAY 1 FORECAST
   PERIOD.
   
   ...SRN NV/NW AZ/SRN DESERTS OF CA...
   A STRONG UPPER LEVEL IMPULSE IS OBSERVED IN EARLY MORNING WATER
   VAPOR SATELLITE IMAGERY OVER THE PAC OCEAN...AND IS FORECAST TO MOVE
   AROUND THE SRN AND THEN ERN PORTIONS OF THE UPR LOW POSITIONED OFF
   THE COAST OF CA TODAY. THIS FEATURE WILL BE ACCOMPANIED BY A 100 KT
   UPPER LEVEL JET...WHICH WILL LIFT THROUGH SRN CA DURING THE
   AFTERNOON...AND THEN INTO THE GREAT BASIN DURING THE NIGHT. MID TO
   HIGH LEVEL CLOUDINESS IS LIKELY AHEAD OF THE IMPULSE...BUT HOT/DRY
   SURFACE CONDITIONS ARE STILL EXPECTED TO MATERIALIZE...WITH MIN RH
   VALUES IN THE TEENS AND SINGLE DIGITS. FORECAST SUSTAINED WIND
   SPEEDS WILL GENERALLY REMAIN BELOW CRITICAL CRITERIA...BUT DEEP
   BOUNDARY LAYER MIXING WILL PROMOTE GUSTS UP TO 30 MPH.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0228 AM CDT WED JUN 03 2009
   
   VALID 041200Z - 051200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A BROAD UPPER LEVEL TROUGH IS FORECAST TO RESIDE ACROSS THE N
   CENTRAL/NERN CONUS ON THURSDAY...WITH SEVERAL WEAK DISTURBANCES
   LOCATED TO ITS S OVER THE SERN STATES. A SURFACE FRONT WILL BECOME
   STATIONARY OVER THE CAROLINAS INTO THE LWR MS VALLEY...WHILE THE WRN
   PORTION OF THE BOUNDARY SAGS S THROUGH MUCH OF SRN TX.
   MEANWHILE...STRENGTHENING SWLY UPPER LEVEL FLOW WILL SPREAD NE INTO
   THE GREAT BASIN AHEAD OF AN UPPER LOW OFF THE COAST OF CA. THIS WILL
   AID IN THE DEVELOPMENT OF A RIDGE OVER THE DESERT SW N INTO THE
   INTERMOUNTAIN W. STRONG LOW LEVEL HEATING AND DEEP MIXING ARE
   EXPECTED BENEATH THE RIDGE...AND MAY OVERLAP WITH STRENGTHENING SWLY
   SURFACE WINDS OVER AZ...RESULTING IN NEAR CRITICAL FIRE WEATHER
   CONDITIONS.
   
   ...CENTRAL AND NRN AZ...
   MUCH OF AZ IS FORECAST TO RESIDE WITHIN THE ERN FRINGE OF STRONGER
   FLOW ALOFT...ASSOCIATED WITH AN UPR JET NOSING NWD INTO THE GREAT
   BASIN. THIS SHOULD AID IN STRENGTHENING SSW LOW LEVEL WINDS...WHICH
   WILL LIKELY APPROACH CRITICAL THRESHOLDS DURING THE AFTERNOON.
   ENSEMBLE GUIDANCE AND MODEL FORECAST SOUNDINGS INDICATE THE HIGHEST
   PROBABILITY FOR RH VALUES BELOW 15 PERCENT WILL BE OVER ERN
   AZ...WITH SLIGHTLY HIGHER VALUES TOWARD CENTRAL AZ. THIS RESULTS IN
   SOME UNCERTAINTY REGARDING WHERE THE BEST OVERLAP OF STRONG WINDS
   AND LOW RH MAY TAKE PLACE...WHICH PRECLUDES A CRITICAL AREA FROM
   BEING ISSUED AT THIS TIME.
