   VALID 062018Z - 062145Z
   
   DEVELOPMENT OF SCATTERED STORMS IS ONGOING ALONG SURFACE FRONT/LOW
   LEVEL CONFLUENCE ZONE EXTENDING BENEATH UPPER RIDGE...EAST OF THE
   MID MISSOURI/UPPER MISSISSIPPI VALLEYS THROUGH NORTH CENTRAL INDIANA
   AND SOUTHWEST OHIO.  PRECIPITABLE WATER CONTENT OF THE AIR MASS
   ALONG THIS BOUNDARY IS HIGH...IN EXCESS OF 2 INCHES...AND HEATING TO
   NEAR 90F OF BOUNDARY LAYER WITH DEW POINTS IN THE MID 70S HAS
   CONTRIBUTED TO STRONG CAPE IN EXCESS OF 3000 J/KG.  DEEP LAYER SHEAR
   WITHIN LIGHT UNIDIRECTIONAL NORTHWESTERLY FLOW IS WEAK...BUT
   THERMODYNAMIC PROFILES ARE PROBABLY UNSATURATED ENOUGH AT MID-LEVELS
   TO PROMOTE THE RISK FOR LOCALIZED DOWNBURSTS AND GUSTY SURFACE WINDS
   ALONG OUTWARD SPREADING OUTFLOWS.  OTHERWISE ...LOCALLY HEAVY
   RAINFALL WILL BE POSSIBLE WITH SLOW MOVING STRONGER UPDRAFT PULSES
   THROUGH EARLY EVENING.
