Evidence / storm surfaces
How Berkeley saw the hail — from two instruments
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.
Radar signature field NEXRAD's hail signatures for this storm: the spots the radar detected from above. A detection overhead is not the same thing as a confirmed stone below.
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.
The storm in context
Where Jul 2, 2026 sits in Berkeley's hail record.
This was Berkeley's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 3rd of the 3 storms we have logged here. Radar put the day's largest stone over Berkeley at 1" — the largest NEXRAD radar signature.
The Jul 2, 2026 convective day was bigger than Berkeley: the same system put hail over 1,147 other tracked cities, 68 of them in Illinois. Nearest: Melrose Park (0 miles north, up to 1"); Lombard (5 miles west, up to 1"); Oak Park (5 miles east, up to 0").
These maps are stills. In the app this date is one of 3 Berkeley 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
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.

How the storm moved
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Reports came from Elmhurst — beyond Berkeley itself.
Damage-capable hail signal
What 1" hail means for Berkeley 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
$221M
Potential roof exposure — 18,429 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 92 jobs
- Illustrative work
- ~$1.4M
Close just 0.5% of the 18,429 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
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 $3,870 on top of the $150 plan.
