How Pontiac saw the hail — from two instruments
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
Radar-estimated hail size
The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
Max size
1.25"
Only the radar-estimated size surface resolved for Mar 10, 2026 — this storm produced no NEXRAD point detections over Pontiac, so there is one map to show, not two.
Where Mar 10, 2026 sits in Pontiac's hail record
This was Pontiac's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 6 storms we have logged here. Radar put the day's largest stone over Pontiac at 1.25" — radar-estimated size aloft.
The Mar 10, 2026 convective day was bigger than Pontiac: the same system put hail over 470 other tracked cities, 100 of them in Illinois. Nearest: Odell (9 miles northwest, up to 1.25"); Cullom (10 miles east, up to 1.25"); Ransom (15 miles north, up to 0.75").
These maps are stills from Pontiac's Mar 10, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.
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.

What 1.25" hail means for Pontiac roofs
Quarter-size and larger hail is where asphalt shingle damage starts in earnest: bruised mats and granule loss that homeowners can't see from the ground. Most people inside the footprint won't know their roof was hit until someone inspects it.
What this storm is worth to a roofer
$36M
Potential roof exposure — 2,962 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

A storm day here is a convective day — it runs from noon to noon
UTC, so late-night hail is grouped with the afternoon storm that
spawned it rather than split across two calendar dates. Ground
reports are public-domain observations from the NOAA Storm
Prediction Center. Radar surfaces are detections and estimates,
not confirmed damage. Last updated Aug 3, 2026.
