Merriman, NE Hail Storm – June 2026

A hail-producing thunderstorm tracked through Merriman, Nebraska on June 4, 2026, producing 2.26-inch stones and generating multiple NWS alerts across the early evening. The event ran through the late evening hours and concluded before 11:00 PM CDT.

What Happened

Dual-polarization radar first flagged significant hail signatures at 8:26 PM CDT, reporting 1.9-inch stones along the storm's leading edge. A later radar-detected alert at 8:53 PM CDT indicated hail in excess of two inches. Between those radar hits and subsequent NWS warnings, spotters and NWS warnings continued to track transient hail cores as the system moved east-southeast.

A spotter at 8:42 PM CDT reported 1-inch hail and noted that this corrected an earlier hail report from seven miles south of Merriman. After the early radar detections, the NWS issued a series of warning-only notices from 9:13 PM through 10:47 PM CDT that carried smaller hail size estimates; those later notices coincided with weakening signatures on NEXRAD and fading echo tops.

Radar-detected alerts and NWS warning-only notices alternated as the storm evolved. Dual-polarization returns showed compact hail cores embedded within a broader thunderstorm complex. Ground observation at 8:42 PM CDT provided spotter-verified hail on the south side of Merriman while the radar track passed across the town's southern approaches.

Damage Assessment

Field reports and NWS local storm reporting recorded small to moderate surface impacts near Merriman's southern approaches. The spotter-verified 1-inch observation at 8:42 PM CDT was the primary ground-truth for this event and corrected the reported location to the area south of town. No Local Storm Reports documented structural collapse or catastrophic damage tied to this event.

Radar-detected hail signatures indicate that larger stones likely fell along a narrow swath east-southeast of Merriman before the storm weakened. Reported impacts in the field were limited to localized exterior damage consistent with 1-inch hail where spotters were present. Vehicle dents, broken yard equipment, and broken tree limbs were possible in the southern outskirts based on the radar overlap with the spotter location; field teams should verify those exposures on site.

What Contractors Should Know

Prioritize inspections for properties along the town's southern and southeastern approaches. The spotter location and radar hail swath place the highest likelihood of surface strikes in that corridor. Start with roofing systems on south-facing and southeast-facing slopes, then move to exposed vehicles, HVAC condensers, and metal trim that show denting or impact marks.

Document all findings with scale-referenced photos and timestamps. Photograph hail-imprinted vegetation and vehicle panels before moving to roof-access work. For asphalt shingle roofs, focus on granule loss and edge fracture patterns; for metal roofs and siding, inspect for pitting and localized dents around penetrations and drip edges.
