Every hail report logged that day

Times are Central Daylight Time. Sizes are in inches, as reported. The comment is the National Weather Service's text as published in the Storm Prediction Center's daily log.

What NEXRAD radar recorded inside the metro

1,032 signatures from 7 radars fell inside the metro's counties on this local date, counting every cell the algorithm rated from a 10% to a 100% chance of hail; 459 were rated 100% and 81 had a maximum expected size of 2 inches or more.

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 Tulsa when its coordinates fall inside one of the metro's 7 counties (Tulsa, Wagoner, Rogers, Creek, Osage, Okmulgee and Pawnee 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.
