AREAS AFFECTED...SRN/ERN IND INTO SWRN OH

CONCERNING...SEVERE THUNDERSTORM POTENTIAL...HEAVY RAINFALL 

VALID 270543Z - 270715Z

A WEAK MID-LEVEL SHORTWAVE TROUGH CONTINUES TO MOVE EWD THROUGH NERN
IND EARLY THIS MORNING.  ATTENDANT SWLY 25-30 KT LLJ AHEAD OF THE
SYSTEM WAS SUPPORTING SLIGHTLY ELEVATED TSTM CLUSTERS FROM NRN/WRN
OH SWWD INTO SWRN IND. STRONGEST STORMS HAVE BEEN AND WILL CONTINUE
TO FAVOR SRN IND INTO SWRN OH DURING THE NEXT FEW HOURS WHERE
ELEVATED BUOYANCY WAS THE GREATEST.  THE KINEMATIC SET-UP FEATURING
A LARGELY UNIDIRECTIONAL SWLY FLOW ALIGNED WITH THE GEOMETRY OF THE
PCPN WILL BE FAVORABLE FOR BACKBUILDING AND SUBSEQUENT TRAINING OF
TSTMS...PARTICULARLY OVER SRN IND.  OTHERWISE...GIVEN THE
TRANSLATION OF THE STRONGEST LLJ CORE NEWD INTO CNTRL/NRN OH AND THE
CONCURRENT RELAXATION OF THE LOW-LEVEL SHEAR...THE TORNADO RISK
SHOULD BE REDUCED EARLY THIS MORNING.
