Blue Mound, KS Hail Storm – June 2025

What Happened

A severe hail storm moved across Blue Mound, Kansas, on June 8, 2025, producing 2.5-inch stones at peak and a long run of radar- and spotter-verified alerts through the afternoon and evening.

The first hail alert came at 1:56 PM CDT for 1.25-inch hail. By 2:37 PM CDT, hail potential had eased to 1 inch, then jumped to 2.5 inches two minutes later at 2:39 PM CDT. Verified alerts continued through the late afternoon, with 2-inch hail noted at 2:57 PM CDT, 3:18 PM CDT, 3:40 PM CDT, and 3:55 PM CDT. Another 2-inch alert followed at 4:53 PM CDT. Hail size then stepped down into the 1.25-inch to 1-inch range, with dual-polarization radar confidence added later in the evening.

Field reports lined up with the radar timeline. At 2:20 PM CDT, a spotter-verified social media report placed 2-inch hail in the storm. At 2:38 PM CDT, another report from Mound City Lake described ping pong ball size hail, and at 3:28 PM CDT a social media report confirmed 2.5-inch hail. Around 3:29 PM and 3:30 PM CDT, emergency manager and social media reports described 1.75-inch hail northwest of Montrose. Another emergency manager photo at 3:44 PM CDT showed measured hail between 2 and 2.5 inches.

Late reports kept the storm active into the evening. At 7:15 PM CDT, a photo from Osceola showed hail just larger than quarter size. At 8:09 PM CDT, a social media photo from Highway 54 showed several stones between half-dollar and golf ball size, along with a large volume of hail and windshield damage reported by Missouri State Highway Patrol troopers.

Damage Assessment

The surface impact was concentrated in a narrow hail corridor with repeated spotter confirmation of large stones across multiple locations. Reports from Mound City Lake, northwest of Montrose, Osceola, and Highway 54 show a storm with more than one hail core and a long-lived hail swath.

The most significant field evidence came from the Highway 54 report at 8:09 PM CDT. Troopers reported several vehicles with damaged windshields and requested MODOT assistance to clear hail from the roadway. That report was paired with photographic evidence of stones in the half-dollar to golf ball range. Earlier in the event, emergency manager photos showed measured hail between 2 and 2.5 inches, and the spotter report at 3:28 PM CDT documented 2.5-inch hail.

The report set also includes several 1.25-inch to 1.75-inch observations. Those stones are large enough to produce roof, siding, screen, and soft-metal impacts in exposed areas, especially where hail repeated over the same corridor. The 0.88-inch report near 6:12 PM CDT and the later 1-inch dual-polarization detections show the storm did not end with the early peak. It continued to produce hail signatures well into the evening.

The damage pattern points to a multi-zone event. Blue Mound was not hit by a single short burst. The reports show successive hail cores and multiple verified observations along the storm path.
