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

Thunderstorms will develop and move into the area this evening and
especially overnight. These storms will bring a risk of heavy
rain, flash flooding and isolated to scattered severe weather
to areas mainly across eastern Iowa. The primary storm concerns
are damaging wind and flooding rain. Areas of repeated storm
activity may produce swaths of 1 to 3 inches to localized areas.
Again this may produce some flash flooding especially in urban
areas.



Isolated thunderstorms are possible area-wide Wednesday morning
and will move southward across the area through Wednesday
afternoon. More thunderstorms will be possible on Saturday.
