Yeah, I used to use weather channel all the time. They updated their site recently, and now it is too confusing. Weather underground has quick easy to get info and forecasts. Accu-weather has nice graphics from a teaching perspective.
For this creative projects you have you may want to direct students to this site. It has a suite of free software that can enhance presentations and even pave the way toward digital storytelling (if that's where you're looking to go).
