central Iowa...northeast Iowa...southeast Iowa and northeast
Missouri.

.DAY ONE...TONIGHT

Thunderstorms are expected mainly north of Interstate 80

20 corridor and from Benton east to Jackson counties.

Hot and humid conditions will continue Saturday, especially along
and south of Interstate 80 with heat indices of 95 to 100 degrees
possible.

A cold front will move through the area Saturday afternoon and
evening, leading to increasing chances of strong to severe
thunderstorms. The main threat will be damaging wind gusts, with
large hail and isolated tornadoes as secondary threats. High
rainfall rates and slow moving storms could lead to localized
flash flooding, especially in urban and poorly drained areas.

Thunderstorm chances then return for Tuesday and Tuesday night.

.SPOTTER INFORMATION STATEMENT...

Rainfall reports over 1 inch will be appreciated.

GENERAL STORM MOTION OF THE DAY:East northeast at 20 mph.
