I woke up to a Winter Storm and wondered how I could make this a lesson

This morning in Kansas, we are experiencing an extreme weather change - yesterday our high was 60 degrees and today at 8 a.m. we have reached our high of 29 degrees.  Plus, there is a potential for ice and snow.  Of course, my learners are hoping for a "snow" day but while they are with me this morning I decided I would take this opportunity to make a science lesson.  I found this article on, "The Science of How a Winter Storm Forms", on the Weather Channel Website.  Will someone help brainstorm some ideas on how to extend this into a deeper, richer, lesson?

Thanks!
