St. Joseph, MO Hail Storm – July 2026

St. Joseph, MO is being struck by a multi-zone hail-producing storm on July 10, 2026, with peak radar-detected hail of 1.59 inches. The storm is tracking through the metro during the late afternoon and remains active.

What Happened

Dual-polarization radar first detected large hail at 1:26 PM CDT, triggering an alert tied to a radar-derived hail detection. That initial radar-detected alert at 1:26 PM CDT reported the largest stones associated with this system.

The NWS issued six additional alerts through the afternoon and early evening as the storm continued to produce hail within the warning area. Key alert times and reported hail sizes are:

• 1:26 PM CDT — radar-detected hail alert associated with the initial large-hail signature.
• 1:58 PM CDT — NWS warning only; reported 1.00-inch hail.
• 2:26 PM CDT — NWS warning only; reported 0.88-inch hail.
• 2:39 PM CDT — NWS warning only; reported 0.88-inch hail.
• 2:43 PM CDT — NWS warning only; reported 0.75-inch hail.
• 3:20 PM CDT — NWS warning only; reported 0.75-inch hail.
• 3:23 PM CDT — NWS warning only; reported 0.88-inch hail.

The alert sequence shows an initial radar-detected hail signature followed by a string of NWS warning-only reports as the storm tracked through the metro. Storm motion is continuing to produce hail across the NWS warning area; conditions may still be developing.

Damage Assessment

Alerts indicate hail spanning a range of sizes during the storm pulse that moved through St. Joseph. Hail in this reported range has repeatedly caused denting to unprotected vehicles and localized damage to asphalt-shingle roofing when impacts are sustained or when several stones fall in quick succession.

Within the NWS warning area for this event, exposed skylights, vinyl siding, and unsecured rooftop equipment are at elevated risk where hailfalls were concentrated. Vegetation and unharvested crops along the tracked path are also subject to foliage loss and bruising in those localized swaths.

What Contractors Should Know

Field teams should prioritize safety and documentation. Confirm power is de-energized before working near downed conductors. Photograph damage with dated, geotagged images showing scale against shingles, siding, and vehicle panels. Tarping and temporary covers are often needed to protect interiors after impact; secure permits and coordinate with property owners and insurers before starting permanent repairs.

Inspect crews should expect a mix of minor denting and localized shingle compromise in the NWS warning area. Avoid walking on wet or recently impacted roofs where granule loss or soft spots exist. Track changes in the active warning area while staging crews, and schedule detailed roof assessments once radar returns and local conditions stabilize.
