Colorado Hail Storm Report, June 26, 2026: Westminster and Broomfield

A hail-producing storm crossed Colorado on June 26, 2026. The National Weather Service logged 3 hail reports inside Red Hawk’s service area that day, the largest at 1.00 inches. Westminster and Broomfield took the most reports.

Every hail report in Red Hawk’s service area

These are National Weather Service Local Storm Reports — hail an observer found on the ground, not a radar estimate. Times are MDT.

By city: Westminster 2 reports, Broomfield 1 report. A hail report always names the largest stone an observer found, not the average size that fell across every roof.

Why 1.00-inch hail matters to an asphalt roof

Damage scales hard with stone size. A one-inch stone falls at about 41 mph and lands with roughly 1.3 joules of energy. A 1.75 inch stone falls at about 65 mph and lands with roughly 16 joules — about thirteen times the impact. Denver-area elevation adds another 8 to 10 percent to fall speed.

Published impact studies put the onset of functional damage near 1.00 inch for three-tab asphalt shingles, 1.25 inches for architectural shingles, and 2.00 inches for Class 4 impact-rated products. The largest report on this day was 1.00 inches, at or near the threshold for three-tab shingles.

The damage usually is not visible from the ground. Hail bruises the shingle — fracturing the mat beneath a surface that still looks intact — and the bruised area then sheds its protective granules over the following months. A roof hit in June can look fine all summer and start leaking by winter.

Radar-estimated hail is not measured hail

Radar hail algorithms output a deliberate high-end estimate of what may exist inside a storm cloud, not a measurement of what landed on your roof. Radar estimates characteristically run above what observers actually recover. Treat the shaded swath on the map as the search area and the ground reports as the confirmed observations. If a contractor tells you radar showed three-inch hail at your address, ask whether anyone measured it.

What to do if you were under it

1. Check from the ground, not the roof. Walking a hail-struck roof is how people get hurt.
2. Look in your gutters. Granules washing off in quantity is the most common early sign.
3. Check soft metal. Roof vents, gutters, flashing, the mailbox, AC condenser fins. Dents in soft metal date the storm.
4. Photograph what you find with your phone. Phone photos carry a timestamp. Do not edit them.
5. Get it inspected. Especially if this storm was months ago — that is exactly when bruising starts to surface.

Radar estimate and ground reports by city — June 26, 2026

The map above is the search area. This table asks two narrower questions for each Red Hawk service-area city: did any NWS ground report come from inside the city’s actual boundary, whatever locality name the NWS filed it under; and did a radar-estimated hail band of 1.00 inch or larger cross that boundary? A ground report is an observation and always lists the city. The band is an MRMS estimate, not a measurement.

Radar estimated hail to 1.00 inch over part of Westminster (about 16 percent of it, in its west part). On the ground, three National Weather Service hail reports came from inside the Westminster city limits, the largest 1.00 inch (measured). One of them was logged by the NWS under the locality name “2 ESE Broomfield”. One of them (“2 ESE Broomfield”) plots within 0.5 miles of the Westminster boundary (see the note below).

Where a report is marked above, its point plots within 0.5 miles of the city line it was placed across. An NWS report position is not surveyed: it is quoted to two decimal places and is derived from a whole-mile distance on a 16-point compass, so a point that close to a line cannot be resolved to one side of it. Those reports are still listed, because they are the National Weather Service record; only the city they are credited to is left open. City boundaries are the U.S. Census Bureau TIGER/Line 2025 place limits; Denver neighborhoods use the City and County of Denver’s statistical neighborhood polygons. A city is listed if any NWS ground report came from inside that boundary, or if a 1.00 inch or larger radar band crosses it; a ground report is never left off for the size of the radar estimate. The 0.50 inch band also crossed 6 other service-area cities with no ground report inside them; those are not listed because hail under one inch rarely damages asphalt shingles and a radar band that small is an estimate below that threshold. A band at or above 1.00 inch also clipped the edge of 1 further service-area city without a ground report inside it, by less than one radar grid cell of area. That is not listed: MRMS is gridded at about one kilometre and the swath it draws is displaced from where the stones landed, so an overlap that small does not establish that hail fell in the city. Bands over cities more than 10 miles from this storm’s own reports belong to other storms on the same day and are not listed here.

Hail duration, warnings and wind

The same system produced 8 Colorado wind reports that day, the strongest 68 mph at Firstview. Wind damage and hail damage look different on a roof and are assessed separately.

CoCoRaHS volunteer observers logged 4 Colorado hail observations on this date, the longest running 9 minutes at Broomfield 2.3 SSW. That network records how long hail fell and what it damaged, which NWS storm reports do not capture.
