The estimated-size surface reached 1.5" aloft; NEXRAD logged no point detections over Mason 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.

Evidence / storm surfaces
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.
Estimated size field 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.
Only the radar-estimated size surface resolved for Feb 19, 2026 — this storm produced no NEXRAD point detections over Mason, so there is one map to show, not two.
The storm in context
This was Mason's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 9 storms we have logged here. Radar put the day's largest stone over Mason at 1.5" — radar-estimated size aloft.
The Feb 19, 2026 convective day was bigger than Mason: the same system put hail over 64 other tracked cities, 31 of them in Illinois. Nearest: Dieterich (5 miles east, up to 1.5"); Edgewood (7 miles south, up to 1.25"); Farina (15 miles south, up to 0.75").
These maps are stills. In the app this date is one of 9 Mason 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.

Storm forensics
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Hail was reported over 245 minutes, from to .
Reports came from Bible Grove and Edgewood — beyond Mason itself.
High damage potential
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

Roofing exposure
Potential roof exposure
$23M
Potential roof exposure — 1,947 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Close just 0.5% of the 1,947 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
February 2028
Claims from this storm can typically be filed until around February 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 $409 on top of the $150 plan.
