A cold front approached Oklahoma from the northwest. Ahead of the cold front, rich moisture was in place with numerous outflow boundaries from early thunderstorms located over parts of the state. Thunderstorms developed over eastern Colorado and southwest Kansas and moved southeast through northwest Oklahoma. The low-level jet pumped even more moist air into thunderstorms, creating favorable wind shear for severe thunderstorms with hail, high winds, and flooding rains. Wind gusts near 60 mph were reported over parts of central Oklahoma, with some damage reported due to the high winds. Large hail was also reported, although reports were more sporadic. Flooding was also reported due to the already saturated ground. Monetary damages were estimated.
