Dahlgren, IL Hail Storm – June 2025

What Happened

A severe hail storm moved through Dahlgren, Illinois, on June 6, 2025, with confirmed 1-inch hail reported in multiple warning areas across the day. The first verified alert came at 7:43 AM CDT, when radar and a spotter both supported 1-inch hail.

The storm remained active through mid-morning. Additional 1-inch hail alerts followed at 10:14 AM CDT and 10:38 AM CDT, both tied to dual-polarization radar detection. Another radar-based alert came at 1:01 PM CDT, again holding at 1-inch hail.

By early afternoon, the signal broadened. At 1:47 PM CDT, radar and spotter verification returned again for 1-inch hail. A separate alert at 1:58 PM CDT carried a warning-only hail threat. The next alert at 2:08 PM CDT returned to radar and spotter verification, also at 1 inch. The final alert came at 3:06 PM CDT, with dual-polarization radar again showing 1-inch hail potential.

A ground report at 3:00 PM CDT, time estimated, noted water over Lola Road and Carrsville Road in northern Livingston County with a spotter-verified 0.75-inch report. That field report placed a late-day impact in the northern part of the county while the hail threat was still active nearby.

Damage Assessment

The field picture points to a storm with repeated hail potential and at least one late report tied to standing water over roadways in northern Livingston County. The spotter note on Lola Road and Carrsville Road did not describe structural damage, but it did confirm surface impact in the storm corridor.

The radar and spotter sequence shows repeated hail verification through the morning and afternoon. Two alerts carried radar and spotter confirmation, three were tied to dual-polarization radar, and one warning-only alert filled the gap between verified reports. That pattern supports a storm with multiple hail pulses rather than a single short burst.

For contractors, the main concern is not just the peak size. It is the repeated timing. Roofs, vents, soft metals, and vehicle surfaces in and around Dahlgren may have taken several passes of hail threat through the day. Properties along the broader Livingston County path deserve attention where later rainfall also produced water over low roads.

The spotter report near 3 PM should not be treated as an isolated note. It lines up with a period of continuing hail alerts and shows that the storm environment remained active into the afternoon. Roadway water in northern Livingston County also suggests crews may encounter access issues on rural routes, drainage swales, and low crossings.

What Contractors Should Know

Plan for a multi-call inspection day rather than a single neighborhood stop. The alert sequence ran from 7:43 AM CDT through 3:06 PM CDT, and the verified reports were spread across that window. In the field, that usually means crews should expect scattered impacts, not one clean line of damage.
