Western Oklahoma is still experiencing a major drought, and climate experts warn it may not get much better.
Experts said in the past 50 years, the dividing line between the drier west and more humid east has shifted 140 miles east and is now along the I-35 corridor.
Experts predict droughts to become more severe in the future.
"If semi-arid conditions are your basic climate, then the droughts change. If what would have been a drought, 50 years ago, suddenly now it's your normal climate," said Gary McManus, State Climatologist.
The state climatologist predicts droughts will become more intense due to increased evaporation.
