I would even settle for something like:
Today:
7 am - partly sunny 60 deg. wind SW 7mph
noon - sunny 70 deg. wind S 15mph
6 pm - sunny 75 deg wind S 10mph
midnight - clear 55 deg. wind calm
low - 55 deg at midnight
high - 77 deg at 5pm
(or whatever times we choose to display)
I know that is not as wordy as Dans suggestion but I could live with the above for now if that would be easier to do while you work on getting a discriptive forcast working properly. Heck, if these items were broken down and WD tags created for each item within a time then we could construct the discriptive part of the text.
