NWS Nashville's Weather101

Weather101 is a series of FREE interactive online classes to help the public learn about meteorology, forecasting and the National Weather Service in general.  These classes will explore the concepts formally found in what was our Advanced SKYWARN spotter classes, plus MORE!

Individuals or groups will be able to complete the courses in the comfort of their own home using the extremely user-friendly computer program, Go-To Meeting.  The only requirement will be speakers to listen, if you're using a computer. If you want to ask questions, you will need to have a VOIP microphone (this is not a requirement). 

Each class can be viewed on a Mac or PC, as well as on your iPad, iPhone or Android device by simply downloading the FREE Go-To-Webinar app in the app store on your device (you'll need the Webinar ID number supplied in the registration email).
