   VALID 270939Z - 271115Z
   
   ISOLATED STRONGER STORMS PRODUCING HAIL WILL BE POSSIBLE EARLY THIS
   MORNING ACROSS PARTS OF CENTRAL/SERN MO INTO SRN IL.  THIS ACTIVITY
   WILL BE LOCATED IN THE VICINITY OF AND PRIMARILY N OF A
   QUASISTATIONARY BOUNDARY WHICH EXTENDED FROM KY WWD THROUGH FAR SRN
   IL TO SRN MO AND INTO SERN KS AND NWRN OK.
   
   REGIONAL RADARS/LIGHTNING DATA INDICATED AN APPARENT INCREASE IN
   TSTM ACTIVITY ACROSS PARTS OF CENTRAL/SOUTH CENTRAL MO DURING THE
   LAST HOUR /SINCE 0830Z/.  THIS INCREASE IS LIKELY TIED TO 1) ASCENT
   ATTENDANT TO A LOW AMPLITUDE SRN STREAM SHORT WAVE TROUGH TRACKING
   EWD ACROSS THE OZARKS/MID MS VALLEY AT THIS TIME...AND 2) WAA ALONG
   NOSE OF A 50 KT SWLY LLJ EXTENDING INTO SRN MO.  THIS IS SUPPORTING
   A RECENT INCREASE IN LOW LEVEL MOISTURE BEING LIFTED ISENTROPICALLY
   ALONG LEADING EDGE OF EML.  THESE FACTORS COMBINED WITH EFFECTIVE
   BULK SHEAR /30-40 KT/ SUFFICIENT FOR STORM ORGANIZATION SUGGEST
   STORMS WILL CONTINUE TO SHOW SIGNS OF SUSTAINED UPDRAFTS THIS
   MORNING...WITH A FEW STORMS PRODUCING HAIL LOCALLY APPROACHING
   AND/OR EXCEEDING SEVERE LEVELS.  OVERALL WEAK INSTABILITY SHOULD
   LIMIT THE HAIL COVERAGE.
