Evidence / storm surfaces
How Nichols 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 signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.
Only the NEXRAD radar-signature surface resolved for Mar 31, 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
Where Mar 31, 2026 sits in Nichols's hail record.
This was Nichols's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 4 storms we have logged here. Radar put the day's largest stone over Nichols at 1" — the largest NEXRAD radar signature.
The Mar 31, 2026 convective day was bigger than Nichols: the same system put hail over 522 other tracked cities, 24 of them in Iowa. Nearest: Conesville (7 miles south, up to 0.75"); Lone Tree (10 miles west, up to 1"); Iowa City (13 miles northwest, up to 1.5").
These maps are stills. In the app this date is one of 4 Nichols 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.
Nobody on the ground filed a report over Nichols for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.
Damage-capable hail signal
What 1" hail means for Nichols 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
$5.8M
Potential roof exposure — 482 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 2 jobs
- Illustrative work
- ~$30K
Close just 0.5% of the 482 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 $101 on top of the $150 plan.
