Evidence / storm surfaces

How Lisco saw the hail — from two instruments

Sep 17, 2026 · Lisco, NE

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-estimated hail size Surface resolved
Map image is still rendering for this surface.

Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.

Max size 1.75"

Only the radar-estimated size surface resolved for Sep 17, 2026 — this storm produced no NEXRAD point detections over Lisco, so there is one map to show, not two.

The storm in context

Where Sep 17, 2026 sits in Lisco's hail record.

This was Lisco's 12th recorded hail day, arriving 31 days after the Aug 17, 2026 storm. By severity it ranks 2nd of the 12 storms we have logged here. Radar put the day's largest stone over Lisco at 1.75" — radar-estimated size aloft.

The Sep 17, 2026 convective day was bigger than Lisco: the same system put hail over 75 other tracked cities, 4 of them in Nebraska. Nearest: Broadwater (13 miles west, up to 1"); Lodgepole (25 miles south, up to 0.75"); Chappell (29 miles south, up to 1.75").

These maps are stills. In the app this date is one of 12 Lisco 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.

Timing and place names from NOAA ground reports

Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.

Reports came from Broadwater — beyond Lisco itself.

High damage potential

What 1.75" hail means for Lisco 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.

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 Sep 18, 2026.
