How Hammond saw the hail — from two instruments

Jul 27, 2026 · Hammond, IN

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 map of the storm over Hammond, IN on Jul 27, 2026 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.

Only the radar-estimated size surface resolved for Jul 27, 2026 — this storm produced no NEXRAD point detections over Hammond, so there is one map to show, not two.

Ground reports

What people on the ground reported

No reports filed with the NWS

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.

No ground reports were filed with the National Weather Service for this storm over Hammond. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.

Damage-capable hail signal

What 1" hail means for Hammond 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.

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 3, 2026.
