What happened

The episode as NWS OUN wrote it up.

For the second night in a row a large line of severe thunderstorms move out of Kansas into Oklahoma during the overnight hours. This line of thunderstorms produced widespread straight-line damage along its path as it entered northwest Oklahoma around 2300 CST on the 20th and moved southeastward toward central Oklahoma through the early morning of the 21st. Although no fatalities or injuries occurred as a direct result of the severe thunderstorms, millions of dollars in property damage was observed. The most widespread and significant damage was observed across Oklahoma County, particularly the Oklahoma City metropolitan area where approximately 75,000 customers were left without power.
