St. Jo, TX Hail Storm – April 2025

St. Jo, TX saw a concluded hail storm on April 19, 2025, with peak verified hail reaching 1.5 inches. Four NWS alerts were tied to the event across the overnight period.

What Happened

The first alert came at 9:47 PM CDT with 1.5-inch hail verified by radar and a spotter. Three later alerts followed during the overnight hours at 2:18 AM CDT, 3:13 AM CDT, and 4:00 AM CDT, each carrying a 1-inch hail threat supported by dual-polarization radar detection.

The sequence shows a hail-producing storm that persisted through late evening and into the early morning. The 1.5-inch hail report stands as the largest confirmed size in the storm set for St. Jo.

Damage Assessment

Hail at 1.5 inches can leave visible impact on roofing, soft metals, gutters, vents, skylights, and vehicle finishes. In St. Jo, the later 1-inch alerts point to a wider hail footprint around the core report, with repeated hail indications through the same storm cycle.

The size range matters in the field. A 1-inch report often produces bruising on roof shingles, cracked plastic components, and scattered exterior marks. At 1.5 inches, contractors should expect a higher rate of roof slope impacts, dented aluminum trim, broken window screens, and exposed damage on rooftop accessories. The overnight timing also raises the chance that some impacts went unreported until daylight inspections.

For property checks, start with north- and west-facing slopes where wind-driven hail often concentrates visible wear. Inspect ridge caps, pipe boots, flashing, and soft metal features. On vehicles, look for consistent pitting across horizontal panels and mirror housings.

What Contractors Should Know

This storm produced multiple hail alerts over roughly six hours, with the strongest verified report early in the sequence and smaller hail signals continuing afterward. That pattern supports a broad canvass in and around St. Jo rather than a single-point check. Crew routing should account for both the peak 1.5-inch hail area and the later 1-inch alert areas.

Focus first on roofs with ages near or past the middle of their service life. Shingle loss may be limited, but bruising and hidden mat fracture are likely where the larger hail core passed. Pay attention to creases in metal drip edge, dents in condenser fins, and damage to gutters, vents, and screen enclosures. Photograph slope-by-slope conditions and separate obvious impact marks from older wear.

For estimate work, use the verified 1.5-inch report as the upper bound and the 1-inch alerts as the outer hail context. That keeps bid language aligned with the event record and the field inspection. If the claim trail is incomplete, daylight verification should start with the most exposed elevations and then expand to surrounding structures along the storm path.
