The estimated-size surface reached 0.75" aloft; NEXRAD logged no point detections over Robinson that day. Open it on the live map to see the swath over the streets.
A tornado was also reported to the National Weather Service during this storm. The ground reports below show where it was filed.

Severity
Overview's storm severity score weighs hailstone size, homes in the footprint, and ground-truth reports.

Evidence / storm surfaces
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
Only the radar-estimated size surface resolved for Jun 21, 2026 — this storm produced no NEXRAD point detections over Robinson, so there is one map to show, not two.
The storm in context
This was Robinson's 2nd recorded hail day, arriving 122 days after the Feb 19, 2026 storm. By severity it ranks 2nd of the 4 storms we have logged here. Radar put the day's largest stone over Robinson at 0.75" — radar-estimated size aloft.
The Jun 21, 2026 convective day was bigger than Robinson: the same system put hail over 415 other tracked cities, 27 of them in Illinois. Nearest: Oblong (9 miles southwest, up to 0.75"); Yale (13 miles northwest, up to 0.75"); Lawrenceville (18 miles south, up to 0.5").
These maps are stills. In the app this date is one of 4 Robinson storm dates on a live map — both surfaces, the reports, and a replay — and the same map is where you draw the swath. This page rebuilds nightly.
Ground reports
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.
“EF-1... max wind 95 mph... path length 2.01 miles... path width 600 yards. The tornado touched down about 3 miles SSE of Annapolis and progressed northeast for 2 miles. (ILX)”
— NOAA / SPC storm report
“TDS observed on radar. (ILX)”
— NOAA / SPC storm report
“EF-1... max wind 100 mph... path length 6.98 miles... path width 600 yards. The tornado began 3 miles southwest of Annapolis and tracked east-northeast toward N825th St (ILX)”

Storm forensics
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Reports came from Eaton and Annapolis — beyond Robinson itself.
Near the severe threshold
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.

Roofing exposure
Potential roof exposure
$6.2M
Potential roof exposure — 516 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Close just 0.5% of the 516 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
Claim window
June 2028
Claims from this storm can typically be filed until around June 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 $108 on top of the $150 plan.
