Hail in Julesburg Jun 30, 2026
Hit 34 days agoBoth radar surfaces caught this storm: NEXRAD logged 0 hail signatures up to 2.5", and the radar-estimated size reached 1.75" aloft. At 2.5" — baseball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

How Julesburg saw the hail — from two instruments
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.
NEXRAD radar signatures
The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.

Radar-estimated hail size
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.

This was Julesburg's 2nd recorded hail day, arriving 7 days after the Jun 23, 2026 storm. By severity it ranks 1st of the 6 storms we have logged here. Radar put the day's largest stone over Julesburg at 2.5" — the largest NEXRAD radar signature.
The Jun 30, 2026 convective day was bigger than Julesburg: the same system put hail over 720 other tracked cities, 27 of them in Colorado. Nearest: Ovid (9 miles northwest, up to 2.5"); Sedgwick (16 miles west, up to 1.75"); Big Springs (17 miles northeast, up to 2.5").
These maps are stills from Julesburg's Jun 30, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.

What 2.5" hail means for Julesburg roofs
Two-inch-plus hail punctures shingles, breaks skylights and windows, and dents anything soft. In the core of a footprint like this, close to every roof is a candidate for an insurance claim. Speed decides who writes those jobs.

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 surfaces are detections and estimates,
not confirmed damage. Last updated Aug 3, 2026.
