Amber dots are radar hail signatures inside the metro's counties (every cell the algorithm rated, 10% to 100% chance of hail), darkest under 1 inch, brighter from 1 inch, brightest at 2 inches and up. Triangles are spotter reports; the filled one is the largest. County names are drawn at each county's center.

Each radar that scans a storm writes its own signature about every 4 to 6 minutes, so one storm produces many rows and overlapping radars count it more than once. The raw rows for this day are in NOAA's Severe Weather Data Inventory.

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 Omaha when its coordinates fall inside one of the metro's 8 counties (the counties of Douglas, NE, Sarpy, NE, Cass, NE, Saunders, NE, Washington, NE, Pottawattamie, IA, Mills, IA and Harrison, IA). 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.
