Evidence / storm surfaces
How Pomona 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.
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.
The storm in context
Where Apr 27, 2026 sits in Pomona's hail record.
This was Pomona's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 2nd of the 7 storms we have logged here. Radar put the day's largest stone over Pomona at 1.75" — radar-estimated size aloft.
The Apr 27, 2026 convective day was bigger than Pomona: the same system put hail over 1,188 other tracked cities, 305 of them in Missouri. Nearest: Mountain View (7 miles north, up to 1.75"); Peace Valley (9 miles southeast, up to 1.75"); West Plains (11 miles south, up to 4").
These maps are stills. In the app this date is one of 7 Pomona 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.

How the storm moved
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Reports came from White Church — beyond Pomona itself.
High damage potential
What 1.75" hail means for Pomona roofs.
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
What this storm is worth to a roofer.
Potential roof exposure
$13M
Potential roof exposure — 1,062 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 5 jobs
- Illustrative work
- ~$75K
Close just 0.5% of the 1,062 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
April 2028
Claims from this storm can typically be filed until around April 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 $223 on top of the $150 plan.
