The Weather World 2010 project at UIUC began as a comprehensive meteorology tutorial designed for a high school/undergraduate level. It has since expanded to include guides to remote sensing and reading weather maps. (Some highlights include optical effects, severe storms, and the basics of weather forecasting.) For folks in the US, it also has current surface and satellite imagery for a number of different atmospheric properties.
