   MESOSCALE DISCUSSION 0578
   NWS STORM PREDICTION CENTER NORMAN OK
   0238 AM CDT MON MAY 12 2014

   AREAS AFFECTED...FAR ERN KS INTO WRN MO

   CONCERNING...SEVERE THUNDERSTORM WATCH 147...

   VALID 120738Z - 120945Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 147
   CONTINUES.

   SUMMARY...A THREAT OF SEVERE WIND OR MARGINAL HAIL COULD SPREAD EWD
   OUT OF WW 147 AND INTO WRN MO. DEPENDING ON CONVECTIVE TRENDS...A
   NEW WATCH IS NOT OUT OF THE QUESTION.

   DISCUSSION...A CLUSTER OF STORMS CONTINUES NEWD FROM NEAR TOPEKA SWD
   TO EMPORIA AND HAS SHOWN SOME SIGNS OF UPSCALE GROWTH AS CELL
   MERGERS HAVE OCCURRED. A MOIST AIR MASS REMAINS AREA-WIDE BUT
   CAPPING APPEARS TO INCREASE WITH EWD EXTEND FARTHER FROM THE
   LARGE-SCALE LIFT TO THE W. A RECENT RASH OF ELEVATED STORMS ACROSS
   CNTRL KS IS INDICATIVE OF THIS ENHANCED LIFT WHICH MAY GLANCE THE
   STORMS IN QUESTION. HOWEVER...FORECAST SOUNDINGS SHOW RELATIVELY
   DRIER AIR AROUND 700 MB INTO MO.

   WHILE A NEW WATCH IS NOT EXPECTED AT THIS TIME...TRENDS WILL
   CONTINUE TO BE MONITORED FOR ANY FURTHER GROWTH OF THIS CONVECTIVE
   SYSTEM.
