Ada, OK Hail Storm – April 2026

A severe hail storm tracked through Ada, OK on April 25–26, 2026, producing 3.5-inch stones spotter-verified and a long sequence of radar-detected hail signatures. The event generated 36 NWS alerts spanning late afternoon into the next morning.

What Happened

The storm initiated in the late afternoon of April 25 with the first NWS alert at 5:22 PM CDT for radar-detected hail. Alerts continued through the evening and overnight, with multiple radar-derived hail estimates evolving from near-inch values to multi-inch signatures in the pre-dawn hours of April 26. Dual-polarization radar returned larger point estimates early on April 26, including elevated returns around 6:12–6:25 AM CDT that produced the most intense signatures on the run.

Spotter activity began in the early evening of April 25 with numerous mPING submissions reporting quarter-inch hail in neighborhoods across the Ada metro. At 6:18 AM CDT on April 26, storm spotters reported the largest surface impact at the intersection of Marlow Road and Rochelle Canyon Road. NWS warnings issued throughout the sequence covered the broad corridor where radar-detected hail signatures repeatedly redeveloped, producing multiple separate warning polygons as the storm regenerated across the metro.

Damage Assessment

Field reports and radar indicate a concentrated impact footprint near Marlow Road and Rochelle Canyon Road. Multiple evening mPING entries document widespread quarter-inch hail across residential areas on April 25. The pre-dawn spotter report at the Marlow Road intersection marks a localized area of severe surface impact. Radar-estimated hail signatures during the early morning hours align with that localized spotter report and with continued NWS alerting across the same corridor.

Observed surface impacts reported to authorities are specific to parcels and road intersections within the NWS warning area for Ada during the event window. Inspectors arriving on site should expect a mix of small-stone impacts across several neighborhoods from the late-April evening pulse, and concentrated, larger-stone impacts near the Marlow Road intersection where spotters measured the largest surface report. Use on-site measurements and photographic evidence tied to GPS coordinates and timestamps when documenting losses.

What Contractors Should Know

Prioritize inspections for properties within the NWS warning area active from late afternoon April 25 through early morning April 26. Start at the Marlow Road and Rochelle Canyon Road intersection and expand outward along the radar-derived hail track indicated by the repeated alerts. For each structure, document roof membranes, ridge caps, gutters, exposed HVAC units, skylights, and vehicle panels with GPS-tagged photos and a short video showing scale. Note the presence of quarter-inch pitting versus larger punctures when present.
