A pacific cold front/dry line moved east through Oklahoma during the late morning hours of the 1st into the morning of the 2nd. Showers and thunderstorms developed along the front, with the aide of an upper level storm system that slowly moved east toward the southern plains. The thunderstorms increased in intensity as they moved/developed east, as better instability was in place. Strong wind shear was also in place, as the nocturnal low-level jet developed. Although hail up to golf-ball size was reported with a few of the thunderstorms as they moved east and northeast, the severe winds were the main threats with storms. Some of the storms caused extensive damage, especially in the Rush Springs area, as they moved northeast from southern into central Oklahoma. Most severe wind gusts were between 60 and 70 mph, but in and around the Rush Springs area, gusts were more likely between 90 and 100 mph. Additional damage occurred further northeast into central Oklahoma. Damage was reported in and around Newcastle, Blanchard, Norman, and Oklahoma City. And most of this occurred as the morning rush was developing. At least 3,000 people were without power across central Oklahoma. The storms continued into eastern Oklahoma by late morning.
