How Plano 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-estimated hail size
Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.

Only the radar-estimated size surface resolved for Mar 10, 2026 — this storm produced no NEXRAD point detections over Plano, so there is one map to show, not two.
Where Mar 10, 2026 sits in Plano's hail record
This was Plano's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 4th of the 7 storms we have logged here. Radar put the day's largest stone over Plano at 0.75" — radar-estimated size aloft.
The Mar 10, 2026 convective day was bigger than Plano: the same system put hail over 470 other tracked cities, 100 of them in Illinois. Nearest: Newark (7 miles south, up to 1"); Sugar Grove (7 miles north, up to 0.75"); Yorkville (8 miles southeast, up to 0.75").
These maps are stills from Plano'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 0.75" hail means for Plano roofs
Hail this size sits right at the edge of the National Weather Service severe threshold. Newer roofs usually shrug it off, but aging or already-worn shingles can bruise, and soft metals — vents, flashing, gutters — often show the first dents.

ground reports
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.
