September 11 Showers/Thunderstorm

4:45 PM Update: A band of showers and an isolated thunderstorm continues to develop across portions of central and western Iowa. Currently this line extends from near Grundy Center to the southwest through Ames, to Guthrie Center and then expands to include a good portion of the southwest corner of Iowa. You can check out the latest radar/satellite combination on the Iowa Chaser homepage.

These showers/thunderstorms continue to develop and move northeastward over time this afternoon and into the early nighttime hours, likely expanding in coverage. The strongest storms are in southern Nebraska currently, and thus the heaviest rainfall amounts with these storms may still come later for southwestern Iowa. Heavy rain and a few rumbles are likely to be the strongest that the storms become, total rainfall amounts should range between a quarter of an inch to an inch in some locations.
