OUN has become the epicenter of a new wasteland and we will never see significant rain again. Squall lines will continue to break apart to avoid Norman and all we will see are the grey undersides of anvils and a vague rise in RH as the lines pass. When Lake Thunderbird dries up, along with all other area lakes and rivers, there will be a mass exodus as in the dustbowl times. Places east of a New Orleans-Little Rock-St. Louis line will be forced to set up refugee camps and shanty towns for the Southern Plains evacuees. Agave cactii will become the predominant flora across central and western Oklahoma, and all deciduous trees west of the Arkansas state line will wither and die......or be consumed by the next raging wildfire.
In a few decades time, tourist flights will be offered leaving from Memphis (the first habitable large city you come to going east on I-40) to fly over the state formerly known as Oklahoma, and participants will be awarded an opportunity to view the ghost-city which stands where Oklahoma City used to before the Great Fire of 2007. The only visible signs of life will be small herds of wild camels which moved into the area after the humans moved out and found it quite to their liking. A few humans, clad in nomad-style clothing and with their faces entirely covered but for eye slits to protect from the perpetual blowing dust will herd these animals around......in their endless quest for the last of the semi-dried-up watering holes.
