Greeley, CO Hail Storm – July 2026

A severe hail storm tracked through Greeley, CO early on July 2, 2026, producing 2.45-inch hail and multiple radar-detected hail swaths across the metro area. The event ran from late evening July 1 into the early morning hours and generated a string of NWS alerts and one spotter-recorded roadway accumulation.

What Happened

From late evening July 1 into early morning July 2 a sequence of 15 NWS alerts tracked the storm, beginning at 11:46 PM MDT and continuing through 3:40 AM MDT. Dual-polarization radar and NEXRAD hail detection flagged repeated returns over the Greeley metro. Several radar-derived alerts reported hail signatures in the 1.00 to 1.68-inch range during the midnight to 1:30 AM window. Later alerts in the sequence were issued as NWS warning-only notices when radar signatures weakened.

A Local Storm Report at 1:15 AM MDT recorded roadway accumulation with hail piled to depths of 2 to 3 inches and included a spotter measurement of 1.25 inches. That ground observation coincided with a cluster of radar hail detections near central Greeley. The combined radar and spotter indicators show the strongest returns crossing the metro in the period around and immediately after local midnight.

Damage Assessment

Field reports and radar overlap point to concentrated surface accumulation on roadways in central Greeley at about 1:15 AM MDT. The Local Storm Report is the only ground-truth entry tied to this event in the available record. Radar-detected hail swaths align with the time and location of the reported roadway coating.

The roadway accumulation reported by the spotter creates documented ground-level exposure for vehicles and pedestrian routes where the coating occurred. Parked vehicles left on streets within the affected swath are at higher risk of panel dents and damaged exterior trim. The accumulation also increases the chance of curbside pooling and temporary drainage obstruction in the specific blocks where the spotter observed the hail depth. No additional Local Storm Reports of roof or structural damage were logged in the dataset for this storm.

Contractors performing initial assessments should treat the spotter-observed roadway accumulation as the primary surface-impact indicator. Photo and timestamp documentation of in-place accumulation will support any subsequent claims or repairs tied to the reported location in central Greeley.

What Contractors Should Know

Begin with a targeted exterior survey of the radar-aligned swath and the area where the Local Storm Report recorded 2 to 3 inches of roadway accumulation. Complete a thorough ground-level inspection before any roof work. Photograph exposed vehicles, ground-level glazing, and drainage in the affected blocks. Record local time and GPS coordinates for each photo using America/Denver timestamps.

On roofs, prioritize inspection of edges, skylights, HVAC housings, and soft-metal flashings. Look for concentrated granule loss, split or punctured roof membranes, and displaced siding in units exposed along the radar-detected path. Clear gutters and downspouts of fused hail where accumulation was reported. Measure embedded hail fragments and compare to the spotter-recorded ground measurements to help establish impact severity in claim files.
