   DISCUSSION...23Z MESOANALYSIS INDICATED INCREASING SBCIN WITH LOSS
   OF DAYTIME HEATING ACROSS THE MID-MS/LOWER OH VALLEY REGION. AS
   FURTHER BOUNDARY LAYER STABILIZATION CONTINUES...THE ARC OF STORMS

   WIDESPREAD REPORTS IN THE 40-55 MPH RANGE. A MARGINAL THREAT MAY
   EXTEND OUTSIDE WW 160 INTO PARTS OF CENTRAL IL...BUT THE OVERALL
