          EAST-CENTRAL AND SOUTHERN ILLINOIS
          INDIANA
          WESTERN OHIO
   
   EFFECTIVE THIS MONDAY AFTERNOON AND EVENING FROM 145 PM UNTIL 900

   TORNADOES...HAIL TO 1 INCH IN DIAMETER...THUNDERSTORM WIND GUSTS
   TO 75 MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE IN THESE AREAS.
   
   THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 60 STATUTE
   MILES NORTH AND SOUTH OF A LINE FROM 35 MILES SOUTH SOUTHWEST OF
   DECATUR ILLINOIS TO 70 MILES EAST OF FORT WAYNE INDIANA.  FOR A
   COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH OUTLINE
   UPDATE (WOUS64 KWNS WOU9).
   
   REMEMBER...A TORNADO WATCH MEANS CONDITIONS ARE FAVORABLE FOR
   TORNADOES AND SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH
   AREA. PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR
   THREATENING WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS
   AND POSSIBLE WARNINGS.
   
   DISCUSSION...INCIPIENT SURFACE-BASED TSTMS ARE EXPECTED TO DEVELOP
   INVOF MIGRATORY SURFACE LOW AND ASSOCIATED WARM FRONT WHERE PRESSURE
   FALLS ARE FOCUSING LOW-LEVEL CONVERGENCE.  HERE...AREA VAD AND RUC
   OBJECTIVE DATA INDICATE VERY STRONG LOW- AND DEEP-LAYER SHEAR WHICH
   WILL SUPPORT SUPERCELLS AND BOWING STRUCTURES CAPABLE OF A FEW
   TORNADOES AND DAMAGING WINDS.  GIVEN THE MAGNITUDE OF THE LOW-LEVEL
   SHEAR AND ANTICIPATED FAST STORM MOTIONS...A TORNADO OR TWO COULD BE
   STRONG AND POTENTIALLY LONG-TRACKED.
   EXPECT ADDITIONAL STORMS TO FORM ALONG THE TRAILING COLD FRONT
   ADVANCING THROUGH SRN IL WITH AN ATTENDANT RISK FOR DAMAGING WINDS
   AND PERHAPS A TORNADO OR TWO.
   
   AVIATION...TORNADOES AND A FEW SEVERE THUNDERSTORMS WITH HAIL
   SURFACE AND ALOFT TO 1 INCH. EXTREME TURBULENCE AND SURFACE WIND
   GUSTS TO 65 KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO 400.
