A cold front made its way southeast through Oklahoma during the day, lying over the northwest half of the state by late afternoon. A humid airmass was in place, with plenty of instability from which thunderstorms could work with. Temperatures ahead of the front were well into the 90s to a few degrees above 100 degrees. The large surface temperature and dew point spreads at the surface made the downburst wind threat very high. Also, with the aide of a stronger mid-level flow and cooling, large hail was also a threat. Thunderstorms developed over southwest Oklahoma by late afternoon/early evening. Other thunderstorms began developing over central Oklahoma. The two areas of thunderstorms merged into a line of severe storms, and even extended a little further northeast, with large hail and damaging winds reported through almost the entire complex. The most damaging storm occurred over central Oklahoma, specifically near Norman and Oklahoma City. Shortly after 7 pm, a wet downburst caused intense rainfall and was accompanied by hail up to golf-ball size and winds that were measured at over 80 mph. Damage was reported over much of Norman, with the most intense damage occurring over the northern half of the city. Almost 33,000 residents were without power, some still without power over 24 hours later. This was due to the numerous power poles/lines that were snapped or blown down. The hail was blown almost horizontally, damaging siding, shattering store signs, and denting automobiles. The highest measured wind gust occurred near SE 12th and Boyd, where the anemometer recorded 82 mph before it malfunctioned due to the wind blown hail. The Norman mesonet site measured a gust of 70 mph. A quick inch of rain occurred in about 15 to 20 minutes. This wasn't the only storm to affect parts of central Oklahoma, as some areas received three different rounds of large hail. The thunderstorms moved east, affecting parts of southern Oklahoma through mid evening. The storms weakened in intensity as they moved into eastern and southeast Oklahoma.
