Back when I used Blogger to publish my blog, I had an AccuWeather sidebar that showed Memphis temperature, radar, 4-day forecast and national map. When I moved to WordPress at the beginning of 2008, I got rid of it because I had other things to deal with (mainly, importing 1500 posts).
The weather sidebar is now back. Scroll down and look to the right to see it. Hope you find it useful in planning your day.
