Mariner's Guide to the 500-Millibar Chart

For those interested in learning more about forecasting and analysis, NWS Nashville puts together a great lineup of advanced Skywarn trainings every year. They conduct them online, so you don’t have to be local to participate. They offer short (~2 hr) classes on a range of topics, including severe storm forecasting, winter weather forecasting, upper air soundings, quasi-linear connective systems, radar interpretation, etc. It’s a great opportunity to learn more about forecasting from the professionals who are out there doing it. I took several of the classes last year and enjoyed them immensely.

Here’s a link to the schedule. They don’t have any of the online courses posted yet, but they should appear as spring approaches: https://www.weather.gov/ohx/skywarn

I recommend “Weather Predicting Simplified.”

Helped me interpret and understand SSB-sourced synoptic charts on a sail across the Atlantic.
