I was looking at the weather block code previously given and did a search as i wanted something more graphical and came across this site
http://www.weatherpixie.comIt allows you to choose your location the type of pixie you want to show your weather and then gives you the html code according to your specification. The great thing about it is that the pixie change its clothes according to the weather of the day.
Below are clickable thumb nails.

this is the configuration page for the pixie

and this is her on my forum.
