   AREA INTO NORTHEAST INDIANA BETWEEN NOW AND 19-21Z...AN AREA OF
   ENHANCED WARM ADVECTION ALONG A NORTHEASTWARD ADVANCING WARM FRONT
   TO ITS EAST MAY BECOME OF FOCUS FOR INCREASING SEVERE POTENTIAL

   NORTHEASTWARD INTO CENTRAL INDIANA.  RAPID BOUNDARY LAYER

   POTENTIAL FOR TORNADIC DEVELOPMENT...INCLUDING THE RISK FOR
   PARTICULARLY STRONG AND DAMAGING TORNADOES...IN ADDITION TO A
