   VALID 031200Z - 041200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER LEVEL TROUGH WILL REMAIN POSITIONED OVER THE N CENTRAL-NERN
   STATES ON WEDNESDAY...WITH A LARGE AREA OF SURFACE HIGH PRESSURE
   BUILDING SWD IN ITS WAKE OVER THE GREAT PLAINS. THIS WILL CAUSE A

   INTO THE LWR MS VALLEY AND S CENTRAL TX...WHILE THE FAR WRN PORTION
   OF THE FRONT BECOMES QUASI STATIONARY FROM WRN NM N INTO ID.
   THUNDERSTORM DEVELOPMENT IS LIKELY ALONG AND AHEAD OF THIS BOUNDARY.
   MEANWHILE...THE W COAST WILL CONTINUE TO BE AFFECTED BY A CLOSED
   UPPER LOW POSITIONED W OF CA...WITH STRONG JET STREAM WINDS
   SPREADING NE TOWARD THE SRN GREAT BASIN.
   
   ...SRN NV/NW AZ/SRN DESERTS OF CA...
   MID/UPPER LEVEL FLOW IS FORECAST TO STRENGTHEN FURTHER ON WEDNESDAY
   AS A 100 KT JET STREAK ROUNDS THE BASE OF A CLOSED LOW OFF THE COAST
   OF CA. THIS FEATURE WILL FAVOR SUSTAINED WINDS NEAR CRITICAL
   LEVELS...WITH STRONGER GUSTS AS THE BOUNDARY LAYER BECOMES WELL
   MIXED. GIVEN THE LOW RH VALUES EXPECTED BY AFTERNOON...ELEVATED FIRE
   WEATHER CONDITIONS WILL BE POSSIBLE.
