As of 8:30 p.m., there were 25 reports of large hail and 15 reports of wind damage in addition to 15 tornado sightings, for a total of 57 severe storm reports.

• All the ingredients are in place for a supercell/tornado to develop
• A strong southwesterly jet stream at 30,000 feet
• 50 mph low jet (surface up to 5,000 ft) with convergent wind and subsequent updraft/updraft
• A strong cold front is approaching from the west
• Warm moist unstable air is carried north from the Gulf of Mexico
