Hastings, IA Hail Storm – August 2026

Hastings, IA is being tracked by a hail-producing thunderstorm on Aug 4–5, 2026, with peak radar-detected hail of 2.37 inches. The storm is active and continuing to produce multiple hail signatures while moving through the metro.

What Happened

Storm initiation began late Aug 4 and continued into the early hours of Aug 5. The NWS issued eight alerts for the system while it moved across Hastings. Early alerts were NWS warning only reports of quarter- to three-quarter-inch hail. Subsequent detections were identified by dual-polarization radar and showed increasing size before tapering.

Alert timeline (local):

• Aug 4 · 11:31 PM CDT (04:31 UTC) – 0.75-inch hail – NWS warning only
• Aug 5 · 12:07 AM CDT (05:07 UTC) – 0.75-inch hail – NWS warning only
• Aug 5 · 12:10 AM CDT (05:10 UTC) – 0.75-inch hail – NWS warning only
• Aug 5 · 12:18 AM CDT (05:18 UTC) – 1.19-inch hail – dual-polarization radar detection
• Aug 5 · 12:22 AM CDT (05:22 UTC) – 1.71-inch hail – dual-polarization radar detection
• Aug 5 · 12:52 AM CDT (05:52 UTC) – 1.96-inch hail – dual-polarization radar detection
• Aug 5 · 2:17 AM CDT (07:17 UTC) – 1.83-inch hail – dual-polarization radar detection
• Aug 5 · 3:43 AM CDT (08:43 UTC) – 1.00-inch hail – dual-polarization radar detection

Radar-derived detections indicate the storm intensified after midnight local time and produced the largest radar signature shortly before 1:00 AM. The system is continuing to move and may produce additional hail cores as it progresses through the metro.

Damage Assessment

Radar detections for this event range from roughly three-quarters of an inch up to just over two inches. Hail of this scale can produce panel dents on parked vehicles and concentrated damage on asphalt shingles. Localized shingle impact and broken glass are possible where cores were strongest.

There are no spotter-verified damage reports published yet for Hastings in this update. Ongoing radar signatures with multiple large-hail detections increase the chance of isolated property damage along the storm path. Inspect vehicles, skylights, and south- and west-facing roofing surfaces first in the immediate aftermath.

What Contractors Should Know

Prioritize triage inspections where radar shows the largest returns and where NWS warnings overlapped populated streets. Photograph all damage with date-stamped images and capture vehicle VINs or addresses for each file. Use tarps on exposed roofing only after confirming structural stability and securing permits or owner consent where required.

Estimate labor needs for dent removal, shingle replacement, and glass repair based on clusters of radar-detected large hail. Expect concentrated workloads in neighborhoods along the storm’s path. Coordinate with local authorities for traffic control during curbside repairs and document any preexisting conditions to separate storm-related loss from prior wear.
