   WIND AND MARGINAL HAIL THREAT.
   
   VISIBLE IMAGERY SHOWS TOWER CU AND WEAK STORMS FORMING OVER WRN MI
   INTO WRN INDIANA NEAR A DRYLINE. AMPLE MOISTURE EXISTS TO THE E WITH
   PRECIPITABLE WATER OF 1.25 TO 1.50 INCHES. ALTHOUGH CIN HAS BEEN
   REMOVED...OVERALL LAPSE RATES PROFILES ARE WEAK. THEREFORE...EXPECT
   A SLOW INCREASE IN CONVECTION AS DESTABILIZATION CONTINUES WITH
   HEATING.
   
   DEEP LAYER FLOW FIELDS ARE MORE THAN SUFFICIENT FOR ORGANIZED STORMS
   WITH 30 KT FLOW JUST OFF THE SURFACE INCREASING TO OVER 50 KT IN THE
   MID LEVELS. INITIAL ACTIVITY MAY EVENTUALLY ORGANIZE COLD POOLS AND
   MOVE NEWD WITH DAMAGING WINDS REQUIRING A WATCH.
