My DH and i took a course in meteorology when we sailed. Very interesting. One week they said the golfers would have a sunny Sunday, but woke up to snow. In the class, they explained what happened and why. It was both funny but interesting. So many many factors go in to forecasting. Very interesting field.
Years ago, my husband and I took a couple of lectures given by the NWS Skywarn/Storm Spotter program. Fun and interesting speakers and classes. We haven’t seen announcements of classes in our area in recent years, but they are apparently still doing this:
