I often find myself wanting to see the forecast more than 10 days out.
To see a longer range forecast, I usually click on calendar, but for about the last 3rd of a month, I then have to select the next month and reload the page with the View button.
This script automates that, or does nothing on any calendar URL with a date at the end.
