Forecast Accuracy Comparisons for Tyler Texas Weather
Tyler Texas Weather provides forecasts that are generated every two hours daily from 6AM until 10PM by WxSim software. We also provide forecasts from the National Weather Service. Below are charts comparing the 10PM "next day" forecast that we generate to the 10PM "next day" forecast from the NWS. These forecasts are then compared to the actual observations for that day. The first chart compares the High forecasts, the second chart compares the Low forecasts, and the third chart shows the delta between each forecast and the actual temperatures.
The fourth chart compares the Mean Absolute Error (MAE) from the forecasts generated each day for the past 30 days to the MAE value for the same period from a year prior. The mean absolute error is an average of the absolute difference between the actual temperature and the forecasted temperature in WxSim forecasts.
The final chart compares the Mean Absolute Error (MAE) from the forecasts generated each day for the past 12 months to the MAE value for the 12 months from a year prior.
