If you want a good radar tool it's not necessarily cheap ($79.95) but it's a really good radar application IMHO »
www.grlevelx.com/grlevel3_2/I use it all the time especially during the stormy season course MyWeather has them beat as far as zoom capabilities but as far as variety of radar data I love GRLevel3 it's one of the applications I am glad I bought especially for severe weather season.
Merry Christmas to you and yours also!
