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 St. Louis when its coordinates fall inside one of the metro's 12 counties (the counties of St. Louis, MO, St. Louis City, MO, St. Charles, MO, Jefferson, MO, Franklin, MO, Lincoln, MO, Warren, MO, Madison, IL, St. Clair, IL, Monroe, IL, Jersey, IL and Clinton, IL). 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.
