Day name for forecast components

Hi all,
I have a glance ‘box’ that shows the forecast for the next 4 days and currently the name is just the component name (which isn’t helpful to others).
Is there a way to name the components to the days of the week?

I’m using Yahoo weather for the forecast and have set the component for day0 to “Tomorrow”, but I’d like to name the other components (assuming today is Monday) “Tomorrrow”, “Wednesday”, “Thursday”, and “Friday”.
I assume this would be done with some python, but I’ve not got round to learning the basics of Python yet.

Thanking you all.
