Hiawatha, KS Hail Storm – June 2026

A severe hail storm tracked through Hiawatha, Kansas on June 4, 2026, producing 2.25-inch hail and generating 14 NWS alerts from mid-afternoon into late evening. The storm produced a mix of NWS-warning-only notices and radar-detected hail signatures during the early evening surge.

What Happened

NWS issued 14 separate alerts tied to the Hiawatha storm between 4:07 PM CDT and 9:55 PM CDT. Early alerts beginning at 4:07 PM CDT carried NWS warning-only hail sizes around 0.75 inch. Dual-polarization NEXRAD radar first flagged larger returns at 6:34 PM CDT, reporting an approximate 1.07-inch detection. Radar detections increased through the next 40 minutes, with measured returns at 6:43 PM CDT and 7:11 PM CDT showing roughly 1.5-inch and 1.75-inch signatures respectively.

A spotter relayed a 1.0-inch hail report at 6:57 PM CDT via emergency communications. That local, spotter-verified observation occurred between the early radar detections and the 7:11 PM CDT radar peak. After 7:11 PM CDT the event returned to a mix of NWS-warning-only alerts and smaller radar returns. A string of NWS-only notices continued through the 8:00–9:55 PM CDT window, including several entries reporting minimal hail or no hail as the system weakened and moved away.

The storm is now concluded for the Hiawatha metro. The evening sequence shows escalation from NWS-warning-only reports in mid-afternoon to radar-detected larger returns in the early evening, with at least one spotter-verified surface observation recorded during the peak period.

Damage Assessment

NWS Local Storm Reports for this event include a single spotter-verified 1.0-inch hail observation at 6:57 PM CDT in the Hiawatha area. No additional public local storm reports of structural or vehicle damage to Hiawatha addresses were logged in the available NWS reports for June 4.

Radar-detected signatures indicated larger stones aloft, but ground confirmation of those larger radar detections was not recorded in the NWS field reports for Hiawatha. Where the spotter-verified report originated, observers reported hail accumulations limited to short-duration surface coverage and no immediate reports of roof failures or widespread broken glass were transmitted through the local observer channels.

Field evidence therefore shows measurable surface impact confined to isolated locations within the Hiawatha area. Contractors conducting field canvass should assume variable impact across short distances and prioritize direct inspection rather than relying on radar size alone.

What Contractors Should Know

Inspect roofs in person. Begin with properties near the reported 6:57 PM CDT spotter location and expand outward along the likely storm motion. Look for shingle granule loss, soft-spot bruising on asphalt shingles, rounded dents on metal seams, and impact marks on HVAC fins. Photograph all findings with a scale reference and timestamp. Take at least three views per suspected impact point: close detail, intermediate context, and a wider shot showing the property's orientation.
