Evidence / storm surfaces
How Idalia saw the hail — from two instruments
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
Radar signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
The storm in context
Where Jul 3, 2026 sits in Idalia's hail record.
This was Idalia's 9th recorded hail day, arriving 1 day after the Jul 2, 2026 storm. By severity it ranks 9th of the 12 storms we have logged here. Radar put the day's largest stone over Idalia at 1" — radar-estimated size aloft.
The Jul 3, 2026 convective day was bigger than Idalia: the same system put hail over 1,885 other tracked cities, 35 of them in Colorado. Nearest: Saint Francis (21 miles northeast, up to 1"); Wray (24 miles north, up to 1"); Kanorado (25 miles south, up to 1.75").

Ground reports
What people on the ground reported
These are storm reports filed with the National Weather Service and released through the NOAA Storm Prediction Center — public-domain observations from spotters, the public, and NWS surveys. We quote each one exactly as filed.
The National Weather Service logged no spotter reports for this storm over Idalia. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.
Damage-capable hail signal
What 1" hail means for Idalia roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$696K
Potential roof exposure — 58 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
July 2028
Claims from this storm can typically be filed until around July 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
Names and phones for every home in the footprint: at most $12 on top of the $150 plan.
