SUMMARY...Severe thunderstorms are expected to develop and quickly
increase this evening initially across northern Kansas and

later this evening into the overnight.
The severe thunderstorm watch area is approximately along and 80
statute miles north and south of a line from 50 miles north of Hill
City KS to 35 miles east southeast of Shenandoah IA. For a complete
depiction of the watch see the associated watch outline update
