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.

What NEXRAD radar recorded inside the metro

967 signatures from 5 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; 470 were rated 100% and 126 had a maximum expected size of 2 inches or more.

Radar	Signatures	Rated 100%	1 in or more	2 in or more	Largest expected	First	Last
KDEN	484	158	177	20	2.50 in	2:07 pm	11:58 pm
KPUX	184	129	112	42	4.00 in	2:02 pm	11:58 pm

KGLD	23	17	14	2	2.00 in	10:07 pm	11:56 pm

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 (Mountain Daylight Time) and by county: a report counts for Denver when its coordinates fall inside one of the metro's 7 counties (Adams, Arapahoe, Boulder, Broomfield, Denver, Douglas and Jefferson 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.
