A strong surface low pressure system moved across northern Oklahoma, a trailing cold front to the west and a dry line across the south. By early evening, the dry line was located over parts of central and southern Oklahoma. Very dry air had overspread the region behind the dry line, with Red Flag conditions rapidly developing. Relative humidity values were in the 5 to 15% range, and southwest to west winds were sustained over 30 mph with gusts over 40 mph. As the cold front moved southeast, winds shifted around to the northwest and winds gusted well over 50 mph at times. Numerous, large grass fires developed, with several structures burned. The wind shifts made fire fighting efforts difficult for several hours. The most costly fire occurred in the Midwest City area, with several homes burning to the ground. The strong winds finally died down during the mid to late evening hours. Monetary damages were estimated.
