Madill, OK Hail Storm – March 2025

A severe hail storm moved through the Madill, OK area on March 25, 2025, producing 1.75-inch hail and multiple radar-verified alerts through the night. Spotter reports in the broader event area confirmed smaller stones earlier in the cycle.

What Happened

The first alert came at 6:32 PM CDT, when radar and spotter verification supported 1-inch hail in the Madill warning area. A ground report followed a minute later from far northwest Marshall on Tiny Chapel Rd., where a spotter measured 0.88-inch hail at 6:33 PM CDT.

The storm stayed active into the late evening and after midnight. A second 1-inch hail alert was issued at 11:16 PM CDT, again with radar and spotter-verified confidence. Eleven minutes later, at 11:27 PM CDT, the warning area climbed to 1.75-inch hail. Another 1.75-inch alert followed at 12:09 AM CDT.

Radar-derived hail signals remained in place well into the overnight hours. Alerts at 12:15 AM CDT, 12:53 AM CDT, and 2:37 AM CDT each carried 1-inch hail estimates based on dual-polarization radar. The storm remained organized enough to keep generating hail signatures across several warning updates.

For Madill and the surrounding highway corridors, the event unfolded in a series of hail-producing pulses rather than one brief burst. The 6:33 PM CDT spotter measurement on Tiny Chapel Rd. fits with the early phase of the storm, while the later alerts show a stronger hail core developing after dark.

Damage Assessment

The field reports show a mixed hail footprint across the event area. The confirmed 0.88-inch report in far northwest Marshall suggests smaller stones on the edge of the hail swath, while later radar and spotter-verified alerts point to a more intense core carrying 1.75-inch hail through parts of the Madill warning area.

No damage report was included with the spotter note, but the hail sizes and repeated warnings point to a storm that was capable of impacting exposed vehicles, roof coverings, and soft outdoor materials along the core path. The early evening report near Tiny Chapel Rd. also indicates the storm reached ground level in a documented spotter location before the midnight sequence.

The overnight radar alerts show the hail threat persisted long enough to affect more than one part of the track. That pattern is consistent with scattered hail impacts across a corridor rather than a single isolated strike point.

For contractors, the first step is to separate the general warning area from the exact hail track. The NWS alerts covered a broader polygon. The strike pattern was narrower, and the strongest hail likely followed the radar core that produced the 1.75-inch alerts after 11:27 PM CDT.

What Contractors Should Know

Start with roofs and vehicles in the documented report area first. Far northwest Marshall near Tiny Chapel Rd. is a direct lead location from the 6:33 PM CDT spotter report. It should be canvassed before moving outward into the rest of the warning area.
