AREAS AFFECTED...SRN IL/SRN IN/WRN KY

CONCERNING...SEVERE THUNDERSTORM WATCH 268...

VALID 061823Z - 062030Z

CONVECTION HAD DECREASED ACROSS WW 268. POTENTIAL FOR LARGE HAIL
APPEARS TO HAVE DECREASED ACROSS MOST OF THE WATCH. HOWEVER...A FEW
CELLS ALONG THE SRN EDGE OF THE WW MAY HAVE HAIL POTENTIAL OVER THE
NEXT FEW HOURS.

LARGE-SCALE FORCING HAS DECREASED ACROSS SRN IN IN THE WAKE OF A
VORT MAX OVER NERN KY. AN OUTFLOW BOUNDARY IN SRN IN WILL CONTINUE
TO MOVE SWD TO NEAR THE OHIO RIVER. CONVERGENCE ALONG THE BOUNDARY
MAY BE ENOUGH FOR THE DEVELOPMENT OF NEW CONVECTION. DEEP LAYER
SHEAR OF 55 KT AND AND THE MODERATE INSTABILITY MAY BE ENOUGH TO
ORGANIZE A FEW STRONG CELLS WITH THE POTENTIAL FOR HAIL.
