DISCUSSION...NUMEROUS STORMS INCLUDING SUPERCELLS THAT INITIATED

KS. VERY LARGE HAIL AND TORNADOES HAVE BEEN REPORTED WITH THESE
STORMS...AND THIS THREAT WILL LIKELY PERSIST DURING THE NEXT 2-3

NUMEROUS STORM MERGERS...AND THE THREAT FOR VERY LARGE HAIL AND
TORNADOES WILL PERSIST NEXT 2-3 HOURS. 

ONSET OF NOCTURNAL COOLING WILL RESULT IN A GRADUAL INCREASE IN
CONVECTIVE INHIBITION...AND STORMS SHOULD BEGIN A WEAKENING TREND BY
03Z. HOWEVER...THE STRENGTHENING LLJ MIGHT FOSTER THE MAINTENANCE OF
ONE OR MORE STORM CLUSTERS INTO THE LATE EVENING...BUT IF THIS
OCCURS PRIMARY THREAT WILL TRANSITION TO DAMAGING WIND.
