Precipitation forecasts (in inches) on August 21, 2021, displayed in Coordinated Universal Time (UTC) from the High-Resolution Rapid Refresh (HRRR) model, are shown with red, yellow, and green lines, while observations are shown with a blue line. The McEwen precipitation accumulation data utilized in this comparison is derived from TVA-collected data. The plot illustrates the discrepancy between the accumulated precipitation forecasts and the actual observations at the McEwen gauge.
