Chester, IA Hail Storm – July 2026

Chester, IA experienced a multi-zone hail event on July 8, 2026, with peak hail measured at 2.23 inches. The storm sequence ran through the late afternoon and early evening and is now concluded.

What Happened

The event began in the late afternoon with an NWS warning at 4:01 PM CDT reporting 1.00-inch hail inside the warning area. Dual-polarization NEXRAD detected a 1.08-inch pulse at 4:34 PM CDT. The NWS issued additional warning-only updates at 5:00 PM CDT and 5:07 PM CDT, each citing 1.00-inch hail in the advisory footprint. At 5:55 PM CDT radar returns and a spotter on the ground verified 1.84-inch hail in the Chester vicinity. Subsequent NWS-only warnings at 6:33 PM CDT and 6:53 PM CDT reported smaller 0.75-inch hail echoes as the system moved east.

Radar and spotter evidence were present for multiple pulses. Dual-polarization radar detected intermediate hail-sized cores early in the sequence. A spotter-verified report at 5:55 PM CDT corroborated strong radar returns later in the event. The maximum observed hail size for the Chester area was 2.23 inches during the multi-zone track. The storm is no longer active in the Chester area.

Damage Assessment

Field verification recorded 1.84-inch hail near central Chester at 5:55 PM CDT, with a peak 2.23-inch measurement recorded within the broader event footprint. No public local storm reports of widespread structural collapse were included in the alert sequence supplied here. Vehicle panels, rooftop shingles, and exposed siding within the mapped hail track should be inspected where radar or spotter detections occurred.

Roofing systems with older or loose asphalt shingles are the most likely to show granule loss and localized tearing where the 1.5–2.25-inch hail cores passed. Automotive body panels should be checked for dents and cracked glass in areas identified by the radar-derived hail track. Photographic documentation dated and geolocated to addresses inside the NWS warning area will support claims that align with the observed hail swath.

What Contractors Should Know

Begin with a prioritized inspection list keyed to the radar-derived hail track and the timing of spotter verification at 5:55 PM CDT. Inspect roofing, skylights, gutters, and HVAC housings first, then move to vehicle and siding assessments. Record measurements and mark sample hail impacts for client files. Use tear-off or overlay decisions based on localized shingle loss and substrate condition rather than event-wide averages.

For temporary repairs, apply industry-standard tarping and fasteners anchored into undamaged substrate. Photograph all temporary work and retain material receipts. Provide clients a clear scoped estimate that separates hail-specific replacement work from preexisting wear. Coordinate with adjusters using the event timeline and the radar- and spotter-verified reports as reference points.
