Harper, TX Hail Storm – March 2025

What Happened

A severe hail storm tracked through the Harper, TX area on March 23, 2025, producing verified hail up to 2.75 inches and a long run of radar-derived alerts through the evening. The storm began drawing confirmed hail reports by 6:03 PM CDT and continued sending 1-inch to 1.75-inch hail signals into late night.

The first cluster came in near 6:03 PM, 6:18 PM, 6:28 PM, and 6:33 PM CDT, with radar and spotter verification on 1-inch, 1-inch, 2-inch, and 1.75-inch hail. A field report at 6:25 PM CDT placed 2-inch hail near Kerrville with a radar-estimated time. Another spotter report at 7:29 PM CDT from near the Methodist Encampment in Kerrville documented 2.75-inch hail, the largest verified stone in the event.

Additional reports followed through the evening. At 8:39 PM CDT, mPING reported hen egg hail at 2.00 inches. Later reports showed smaller but still damaging stones, including dime to nickel hail at Braker Lane and I-35 at 9:10 PM CDT, then multiple 0.5-inch to 1-inch reports after 9:00 PM. Radar alerts remained active through 11:15 PM CDT, with several 1.25-inch to 1.75-inch detections and two dual-polarization radar detections at 8:26 PM CDT and 10:09 PM CDT.

Damage Assessment

The field reports point to a storm with a broad hail footprint and repeated ground truth across the evening. The strongest reports came from the Kerrville area, where spotters documented 2-inch hail near Methodist Encampment and a 2.75-inch report near the same corridor. Later reports showed a mix of dime, nickel, and quarter-size hail across additional points, including Braker Lane and I-35, where hail reached 0.88 inch.

That pattern is consistent with a storm that produced isolated larger stones within a wider hail swath. The sequence of reports includes multiple 1-inch and 1.25-inch observations, then separate 1.5-inch and 1.75-inch detections, along with spotter-verified reports at 0.75 inch and 0.5 inch later in the night. The reports from social media and mPING align with the radar-derived hail alerts and show a long-lived storm with several rounds of hail rather than a single short burst.

The heaviest stones were not confined to one minute or one block. Reports came in across a span of more than five hours, from early evening into after 11 PM CDT. That timing fits a storm complex that produced repeated surface impacts across the Harper-Kerrville corridor and nearby travel routes.

What Contractors Should Know

This event created several inspection targets across central Kerr County and the Harper area. Roof systems with asphalt shingles, modified bitumen, and older metal panels should be checked for localized strike marks, lifted tabs, exposed mat, and soft-metal dents. Vehicle fleets in open lots should be inspected for windshield damage and roof dimpling, especially where hail reports reached 1.75 inches and above.
