Mission, TX Hail Storm – May 2026

Mission, TX is experiencing a developing hailstorm on May 21, 2026, producing a peak hail size of 1.45 inches and continuing convective activity that is tracking through the city.

What Happened

A severe thunderstorm moved into the Mission area early on May 21 and is still active. The National Weather Service issued a severe thunderstorm warning at 3:42 AM CDT for 0.75-inch hail; that alert is recorded as NWS warning only. Radar continues to detect strong reflectivity cores and dual-polarization signatures consistent with hail-producing convection as the cell tracks east-southeast through the municipal area. This single-zone report covers the Mission municipal boundary and adjacent corridors where storm returns remain intense. Conditions may still be developing and additional warnings or updates from the NWS are possible.

Damage Assessment

Hail up to 1.45 inches in diameter poses a risk to common property types in Mission. Exposed vehicle surfaces are likely to sustain denting to body panels and potential damage to glass on sunroofs. Asphalt shingle roofs without recent replacement or that show pre-existing granular loss are at elevated risk for bruising and accelerated wear where direct impacts occur. Vulnerable equipment such as rooftop HVAC units, window AC condensers, and unshielded skylights or solar panels can incur impact damage that reduces operational life.

Observed and potential impacts are concentrated along the storm’s current track through Mission. Field inspections should prioritize photographic documentation of vehicles, roof coverings, and outdoor mechanicals. Record the local time of observation and the location within Mission for each photographed asset.

What Contractors Should Know

Safety first. Work only after storms and lightning have ceased and after local officials clear the area. For roof inspections, use binoculars for an initial assessment when possible. If walking roofs is necessary, use fall protection, soft-soled shoes, and limit time on steep or wet surfaces. Inspect for granule loss, split or bruised shingles, damaged flashing, and holes in membrane systems. Tag and photograph all findings with timestamps and GPS coordinates when available.

Scheduling and client communication should be direct and dated. Offer temporary tarps for open roof penetrations and document tarp installation with photos and time stamps. Provide written estimates that separate emergency temporary work from permanent repairs. Coordinate with policyholders on adjuster access and avoid permanent repairs until adjuster confirmation where insurance is involved. Prioritize critical facilities and repeat-loss properties for immediate attention.
