bowing segments, as well as marginally severe hail.  Farther east, a

few pulse-type storms could produce downbursts or hail into central

Kentucky, ahead of the main thunderstorm band.



The severe thunderstorm watch area is approximately along and 100

statute miles east and west of a line from 25 miles northwest of

Louisville KY to 50 miles west southwest of Bowling Green KY. For a

complete depiction of the watch see the associated watch outline
