NEXRAD logged 5 hail signatures up to 0.75"; the estimated-size surface had no signal 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.
Largest radar-indicated size — a signal of damage potential, not confirmation.

Independent storm reports filed with the NWS.
Evidence / storm surfaces
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Radar signature field The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.
Only the NEXRAD radar-signature surface resolved for Mar 15, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
The storm in context
This was Pana's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 4th of the 6 storms we have logged here. Radar put the day's largest stone over Pana at 0.75" — the largest NEXRAD radar signature.
The Mar 15, 2026 convective day was bigger than Pana: the same system put hail over 695 other tracked cities, 58 of them in Illinois. Nearest: Tower Hill (9 miles southeast, up to 1"); Moweaqua (9 miles northeast, up to 0.5"); Shelbyville (11 miles east, up to 1").
These maps are stills. In the app this date is one of 6 Pana 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.
“The tornado touched down just southwest of Assumption and town along W Illinois St where it uprooted and snapped numerous trees and knocked over a couple power poles. T (ILX)”

Storm forensics
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Reports came from Assumption — beyond Pana 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
$2.3M
Potential roof exposure — 190 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Close just 0.5% of the 190 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
March 2028
Claims from this storm can typically be filed until around March 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 $40 on top of the $150 plan.
