   SUGGEST POTENTIAL FOR A FEW SUSTAINED STORMS/SUPERCELLS WITH LARGE
   HAIL/LOCALLY DMGG WIND INTO EARLY EVE /REF MCD 755/. MOST OF THE
   STORMS SHOULD...HOWEVER...MERGE INTO SHORT LINES LATER THIS
   EVE...WITH A DIMINISHING RISK FOR SVR WIN/HAIL.

   TO 2 INCHES. EXTREME TURBULENCE AND SURFACE WIND GUSTS TO 60
   KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO 500. MEAN STORM
