This Hazardous Weather Outlook is for portions of northwest Iowa,
west central Iowa, southwest Minnesota, northeast Nebraska,
central South Dakota, east central South Dakota, south central
South Dakota, and southeast South Dakota.

.DAY ONE...Today and Tonight

Showers will continue today, most concentrated this morning from
southeast South Dakota through far northwest Iowa into southwest
Minnesota. A few locations may see total rain since midnight
approach one to two inches near an axis from Tyndall to Sioux
Falls. This could worsen ponding of water in low-lying and poor
drainage areas, and add to rises in smaller creeks and streams.

Isolated thunderstorms are possible early this morning south of
Interstate 90, then again during the afternoon across mainly
northwest Iowa. Severe weather looks very unlikely.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

No hazardous weather is expected at this time.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not expected at this time.
