The Weather Research & Forecasting (WRF) model was utilized to simulate atmospheric conditions in and around the Oklahoma City area. The WRF output was compared to surface observations from the Oklahoma City Micronet and the Oklahoma Mesonet to show model accuracies and biases. National Land Cover Dataset (NLCD) was modified to represent land use characteristics from 1890, following the Oklahoma Land Rush, to 2011. The WRF model was run with modified NLCD land use datasets to determine the impact from a developing metropolitan area. Results show an increase in urban heat island indices throughout the past 120 years. Additionally, challenges associated with utilizing alternate land use datasets in WRF and different methodologies for interpreting urban heat characteristics are presented.
