A weak cold front moved through northern Oklahoma during the morning and early afternoon, with several outflow boundaries behind the front. Thunderstorms developed by mid afternoon and continued through the early part of the evening along these boundaries, with several briefly becoming severe. Weak winds aloft and marginal instability allowed for more pulse type storms, with heavy rain and strong winds the main impacts. Some hail was reported as well, but these reports were few and far between. Some damage was reported with the winds, especially in the Oklahoma City metro area. Monetary damages were estimated.
