   VALID 100639Z - 100845Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 456
   CONTINUES.
   
   TRAINING THUNDERSTORMS CONTINUE ACROSS SRN IA...WHERE A SWLY LOW
   LEVEL JET AND HIGH PRECIPITABLE WATER VALUES ARE RESULTING IN VERY
   STRONG MOISTURE FLUX INTO THE REGION. AS AN UPPER SHORTWAVE TROUGH
   CONTINUES TO TRAVERSE THE REGION...THE STRONGEST LIFT SHOULD
   GRADUALLY SHIFT E AND NEWD...WHICH MAY ALLOW FOR VERY HEAVY RAINS TO
   MOVE INTO ERN IA AND NRN IL LATER TONIGHT.
   
   AMPLE SHEAR REMAINS FOR SEVERE STORMS...BUT AT THIS POINT THE
   PRIMARY THREAT WILL BE HAIL WITH THE SRN MOST STORMS WHICH WILL HAVE
   AN UNINTERRUPTED INSTABILITY FEED.
