Morrison, TN Hail Storm – August 2026

A hail-producing thunderstorm affected Morrison, Tennessee on August 17, 2026, producing peak hail of 1.09 inches and multiple severe-warned circulations across the metro area.

What Happened

NWS issued 27 severe thunderstorm warnings for the Morrison, TN metro between 2:02 PM CDT and 8:41 PM CDT on August 17. Most warnings carried a 0.75-inch hail estimate. Two warnings noted 0.88-inch hail at 5:03 PM CDT and 6:37 PM CDT. The alert sequence shows repeated reissuance and overlapping warning polygons as the storm complex moved through the area in late afternoon into early evening.

Radars detected hail signatures through the event window and NWS warnings were based primarily on those radar indications rather than widespread spotter reports. The storm is no longer active. Local storm response and inspections began after the last warning at 8:41 PM CDT.

Damage Assessment

Warnings and radar estimates for Morrison clustered around 0.75 inch, with pockets of stronger returns to 0.88 inch. Hail of this size commonly produces cosmetic damage to soft materials and dents to exposed metal surfaces. For this event, expect isolated impacts on residential roofing shingles, vinyl siding, and vehicle body panels in neighborhoods under the stronger radar returns.

Hail larger than the primary warning estimates can occur in narrow swaths. Field crews should prioritize properties located along the storm's higher-reflectivity corridor where radar returns intensified in the 5:00–7:00 PM CDT window. Document roof slope, material, and preexisting wear when assessing shingle loss or granule displacement.

What Contractors Should Know

Start with safety and access. Clear photographs from ground level and multiple angles are essential. Record the exact inspection time, the address, and visible hail-related impacts such as dent patterns on vehicles, bruising on soft metals, concentrated shingle granule loss, and punctures to skylights or trim. Use measurements or reference objects in photos to show scale. Note that many local NWS warnings for this event were based on radar detection rather than spotter networks, so visual documentation on site is the primary evidence for claims and repairs.

For repair planning, prioritize houses with steep exposure and minimal recent maintenance, plus commercial rooftops with thin membrane systems. Expect most repairs to be categorical cosmetic or localized replacements when the hail size aligns with the warning estimates. Coordinate with adjusters and provide clustered inspection logs for properties that fall along the same damage corridor. Keep a separate ledger for vehicles and outdoor equipment photographed at the time of inspection.
