Hail in Roger Mills County, Oklahoma

An image showing a ruler measurement was relayed by emergency management. The location is approximate.

A multi-modal episode of severe thunderstorms occurred from the late evening of the 6th through early morning of the 7th, primarily impacting areas along the north of Interstate 40. Initial severe weather was focused along a modifying warm front, lifting northward into portions of central/west-central Oklahoma. Thunderstorms in this regime produced reports of very large hail and a few severe-caliber wind gusts. Concurrently, a long-track and occasionally tornadic supercell was moving into portions of far western Oklahoma. While no tornadoes occurred across the WFO Norman Forecast Area, this thunderstorm produced large hail in Beckham County. By the early morning of the 7th, a mesoscale convective system (MCS) organized and became well-defined/mature as it swept eastward across northern Oklahoma. Widespread and locally intense thunderstorm wind damage/gusts, and two brief tornadoes, were noted across this area.
