You talking for a desktop or for a mobile device?
My new media phone came with an Accuweather.com widget. Gives me temp (actual and their RealFeel), humidity, pressure tendency, wind (including gusts), and cloud cover percentage. Radar (w/just discovered animation) has come in handy. There is even a Flight Delay search feature (have no use for that).
6 and 15 day forecasts are available, but really anything beyond 24 to 36 hours is just isn't the most accurate here in OK.
