The Categorical Probability Charts (National, Regional, City) have been upgraded to include grid-corrections.

New evolution charts have been added below the main chart of each to show the change in probability for each forecast day from model run to run (click on legend to right of chart to toggle forecast days).

Check out the ERCOT example here (scroll down below main chart to see evolution charts and click on/off forecast days on right legend).

Find them under the Features and City Plots sub-menu.
