Hail in Colby · Jun 20, 2026
The estimated-size surface reached 2.5" aloft; NEXRAD logged no point detections over Colby that day. At 2.5" — baseball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

Evidence / storm surfaces
How Colby saw the hail — from two instruments
Jun 20, 2026 · Colby, KS
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
Radar-estimated hail size Surface resolved
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
Max size
2.5"
Only the radar-estimated size surface resolved for Jun 20, 2026 — this storm produced no NEXRAD point detections over Colby, so there is one map to show, not two.
The storm in context
Where Jun 20, 2026 sits in Colby's hail record.
This was Colby's 5th recorded hail day, arriving 19 days after the Jun 1, 2026 storm. By severity it ranks 1st of the 18 storms we have logged here. Radar put the day's largest stone over Colby at 2.5" — radar-estimated size aloft.
The Jun 20, 2026 convective day was bigger than Colby: the same system put hail over 298 other tracked cities, 121 of them in Kansas. Nearest: Levant (12 miles northwest, up to 3.5"); Brewster (15 miles northwest, up to 3.5"); Monument (17 miles south, up to 1.75").
These maps are stills. In the app this date is one of 18 Colby 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.

Storm forensics
How the storm moved
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.
The storm tracked southwest at roughly 5 mph, based on the timing of ground reports.
Hail was reported over 111 minutes, from to .
Reports came from Rexford, Halford, Gem, and Page City — beyond Colby itself.
Severe hail signal
What 2.5" hail means for Colby roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

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 11, 2026.
