| Two Week GFS 500mb Height Anomaly Correlation Coefficient (ACC)
Last two weeks of 500 mb height ACC for the Arctic region (north of 60 N), Mid-Latitudes (60 N to 20 N), CONUS (between 25 N and 50 N, between longitude 235 and 295) and North Altantic (between 20 N and 75 N, between longitude 270 to 360) for day-3, 5 and 7 forecasts.

| Two Week GFS 500mb Height Root Mean Square Error (RMSE)
Last two weeks of 500 mb height RMSE for the Arctic region (north of 60 N), Mid-Latitudes (60 N to 20 N), CONUS (between 25 N and 50 N, between longitude 235 and 295) and North Altantic (between 20 N and 75 N, between longitude 270 to 360) for day-3, 5 and 7 forecasts. 95th percentile is calculated using the last 90 days and plotted with a dashed line.

| Four Panel Plot of 500mb Heights
Panel 1: Verfying 500 mb height analysis contoured with normalized anomalies in colorfill. Panel 2: Day-3 forecasted 500 mb heights in solid contour, verfying analysis 500 mb heights in dashed contours, and the difference between forecast and analysis (F-A) in colorfill.
