| Radar | Signatures | Rated 100% | 1 in or more | 2 in or more | Largest expected | First | Last |
|---|---|---|---|---|---|---|---|
| KFSD | 134 | 57 | 54 | 9 | 2.50 in | 2:10 am | 10:05 pm |

Spotter reports come from the Storm Prediction Center's preliminary daily logs, grouped here by local calendar date (Central Daylight Time) and by county: a report counts for Sioux Falls when its coordinates fall inside one of the metro's 4 counties (Minnehaha, Lincoln, Turner and McCook counties). Radar signatures are estimates from the Hail Detection Algorithm, not measured stones; they include every cell it rated, from a 10% to a 100% probability of hail. How these pages are built.
