   MESOSCALE DISCUSSION 0332
   NWS STORM PREDICTION CENTER NORMAN OK
   0741 AM CDT SUN APR 13 2014

   AREAS AFFECTED...CENTRAL AND NRN MO/SRN IA/WEST CENTRAL IL/SERN NEB

   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 

   VALID 131241Z - 131445Z

   PROBABILITY OF WATCH ISSUANCE...20 PERCENT

   SUMMARY...TSTM COVERAGE WILL CONTINUE TO INCREASE ACROSS CENTRAL/NRN
   MO AND SERN NEB...WITH ACTIVITY SPREADING/DEVELOPING INTO SRN IA AND
   WEST CENTRAL IL THROUGH THE MORNING.  HAIL WILL BE THE PRIMARY
   THREAT WITH STRONGER CORES...BUT THE POTENTIAL FOR HAIL TO EXCEED
   SEVERE VALUES IS LOW AT THIS TIME.  THUS...PRECLUDING THE NEED FOR A
   WATCH AT THIS TIME.

   DISCUSSION...SINCE 1115Z...MOSAIC RADAR IMAGERY SHOWED A ROBUST
   INCREASE IN TSTM DEVELOPMENT FROM EAST CENTRAL TO NRN MO INTO SERN
   NEB.  EXCEPT FOR THE STORMS IN SERN NEB...THE REST OF THIS ACTIVITY
   WAS LOCATED SOUTH OF A COLD FRONT WHICH AT 12Z EXTENDED FROM NERN IL
   WSWWD THROUGH FAR SRN IA...INTO FAR NWRN MO...AND NERN KS TO AN AREA
   OF LOW PRESSURE IN SWRN KS /NEAR 35 SE DDC/.  HOWEVER...MUCH OF
   THESE STORMS WERE LOCATED NORTH OF A RESIDUAL OUTFLOW BOUNDARY THAT
   EXTENDED FROM SOUTH CENTRAL MO WNWWD INTO EAST CENTRAL KS. 12Z
   SOUNDINGS AT TOP/SGF SUGGEST THE STORMS INTO SERN NEB TO NRN/CENTRAL
   MO WERE LIKELY ELEVATED AND ROOTED AROUND 700 MB.

   HEIGHT FALLS WILL PERSIST ACROSS THE DISCUSSION AREA AS A LEAD
   TROUGH SHIFTS ENEWD ACROSS KS/OK TODAY.  THIS COMBINED WITH LOW
   LEVEL WAA CONTINUING FROM THE LOWER MO VALLEY INTO SRN IA/WRN IL
   WILL SUPPORT ADDITIONAL TSTMS DEVELOPING AND SPREADING N/NEWD. 
   STEEP MIDLEVEL LAPSE RATES /8-9 C PER KM/ ACROSS THIS REGION...
   MARGINAL-MODERATE INSTABILITY AND AN INCREASE IN EFFECTIVE BULK
   SHEAR WILL SUPPORT A POTENTIAL FOR ORGANIZED STORMS.  THUS
   FAR...WDSS-II MESH HAS INDICATED SPORADIC HAIL SIGNATURES GENERALLY
   BELOW SEVERE VALUES...WHICH PRECLUDES THE NEED FOR A WW AT THIS
   TIME.
