Projects have auto-weather enabled which provides a weather entry 3 or 6 times per day. Weather is automatically added to the Daily Report at approximately 7am, noon, and 5pm. You will need to have a city and state or ZIP code filled out in your project information section for accurate readings.
To disable or re-enable Auto-Weather for your project::
Navigate to the project you wish to edit the auto-weather options for
Go to 'Project Settings' (you must be a project admin to do this)
Go to 'Report Settings.'
Scroll until you see 'Auto-Weather' and you can edit the settings there.
Weather entries can also be added manually.
