SPC SAYS: STRONG STORMS HAVE DEVELOPED OVER SERN MO/WRN TN...AND VISIBLE IMAGERY SHOWS TCU/INITIAL THUNDERSTORMS DEVELOPING OVER SRN IN AND NRN/CNTRL KY. CONVECTION MAY CONTINUE TO DEVELOP ACROSS THE AREA AND TRENDS WILL BE MONITORED FOR INTENSIFICATION AND A POSSIBLE WW. LOW LEVEL MOISTURE/INSTABILITY AXIS IS LOCATED FROM SERN MO/NERN AR INTO ERN KY AHEAD OF A DIFFUSE FRONTAL BAND MOVING SLOWLY SWD ACROSS THE NRN PART OF THE OH VALLEY. POTENTIAL INSTABILITY IS ENHANCED BY DRY AIR IN MID/UPPER LEVELS AS INDICATED BY WATER VAPOR IMAGERY...WITH LATEST OBJECTIVE MESOANALYSIS SHOWING MLCAPE OF 2000-3000 J/KG ACROSS THE DISCUSSION AREA. MODERATE DEEP LAYER SHEAR OF 25-35 KT WILL AID IN STORM ORGANIZATION...WITH A THREAT FOR LARGE HAIL AND DAMAGING WINDS AS STORMS CONTINUE TO DEVELOP THIS AFTERNOON AND EVENING.
