Evidence / storm surfaces
How Bartlett saw the hail — from two instruments
Apr 14, 2026 · Bartlett, IL
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Radar-estimated hail size Surface resolved
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
Max size
1"
Only the radar-estimated size surface resolved for Apr 14, 2026 — this storm produced no NEXRAD point detections over Bartlett, so there is one map to show, not two.
The storm in context
Where Apr 14, 2026 sits in Bartlett's hail record.
This was Bartlett's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 3rd of the 7 storms we have logged here. Radar put the day's largest stone over Bartlett at 1" — radar-estimated size aloft.
The Apr 14, 2026 convective day was bigger than Bartlett: the same system put hail over 476 other tracked cities, 44 of them in Illinois. Nearest: South Elgin (5 miles west, up to 1"); West Chicago (7 miles south, up to 1"); Barrington (7 miles north, up to 0.75").
These maps are stills. In the app this date is one of 7 Bartlett 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.

Damage-capable hail signal
What 1" hail means for Bartlett 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.
28,172 homes × $12,000 avg. claim
Potential roof exposure
$338M
Potential roof exposure — 28,172 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 141 jobs
- Illustrative work
- ~$2.1M
Close just 0.5% of the 28,172 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.

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 tells you where to look. Only an inspection confirms damage at an address. Last updated Aug 10, 2026.
