Latest 7 day Costello Graph

Figure Description:
This graphic is similar to the 1-day plot but shows the most recent 7 days of model output. In addition, simple statistics are calculated on this 7-day sample to characterize the model's performance in terms of accuracy (rms error), bias (mean error), association (correlation), and skill or prediction efficiency (relative error). Updating page with graph only.
