I suggest you ...

Add UV Index - Current and Historical

Add a UV Index graph similar to the Sun, Clouds and Precipitation graphs. Perhaps the UV index could somehow included in the Sun graph.

        This would be a great feature, altho most weather sites only give one number for the day and that would not make a great graph. However, at http://www.uvawareness.com/ they give numbers that vary throughout the day by the hour. It would be interesting to know where they get the data, how far back (and forward) it goes, etc.
        For example this is what they have for Philadelphia as of 4/6/12 at 20:03: (sorry formatting got messed up)
        Friday Saturday Sunday Monday
        6A low low low low
        7A low low low low
        8A low low low low
        9A low low low low
        10A low low low low
        11A mod 4.2 mod 4.2 mod 4.4 mod 4.2
        12P mod 5.3 mod 5.3 mod 5.6 mod 5.2
        1P mod 5.8 mod 5.8 high 6.1 mod 5.7
        2P mod 5.4 mod 5.3 mod 5.7 mod 5.3
        3P mod 4.2 mod 4.2 mod 4.5 mod 4.0
        4P low low low low
        5P low low low low
        6P low low low low

        We'd love to add the UV index, but it's hard to get historical data for it. It depends on changing factors in the upper atmosphere (read: ozone layer) and the more precise cloud conditions.

        The info available is primarily current/forward looking data, and it's available more or less only for noon, not other times of day. This make it fit somewhat poorly with our graphs.

        Will look into ways to overcome these issues.
