Watch https://www.youtube.com/watch?v=rYmmqS8Oxag and https://www.youtube.com/watch?v=qTPsoDs-rcM Those are links to Tornado Video Classics volume i and ii. They're from the late 80s/early 90's , there are 3 parts but I can't seem to find the 3rd one on youtube. It's a combination of educational film and documentary, from the first tornado ever caught on film forward to the 90's. It's an excellent source to learn some fundamental information about tornadoes. If for some reason the links didn't show , you can just look them up on the tube.
As far as following the weather, the more you know about what you're looking at the better you'll want your radar, maps, etc to be. I'm seemingly in a similar boat as you are. I have very minimal knowledge about certain parts of weather. Especially when it comes to "The right conditions for a tornado" there are so many variables that I have yet to learn them all. I know what cape is, and cap, and mesocyclones, and different cloud types, and scud, and things like that, but when it comes to the numbers, I'm clueless still. So I don't use the more fancy weather radars (GRLevel2 or GRLevel3) which provides 3D animations and an entire arsenal of tools and and graphs and radar options that i would be just completely absurdly lost while reading lol.. though It may not be the same for you. I'm kind of a slower learner so it'd take me quite a while to get used to it.. I haven't used radarscope but that's the next best thing I hear so many people get that, which is an App for android or iPhone, 10 dollar one time fee. unless you subscribe which just basically gives you the addition of lightning strikes, which is silly... i dont really know many people who pay for the subscription. for me? I simply use the weatherunderground website or app. and on occasion i'll just google random interactive radar websites n mess with those ..
I don't chase, which, I want to do in the very near future, for search and rescue and photography purpose, so I'd like to beef up on my weather knowledge as well. Or I'll just have to team up with someone who knows more than me..plus i don't want to chase alone. I'd like to be a part of a team . Though i have zero intention of core punching or intercepting etc, so I feel that even at my very basic knowledge of storms that I could safely chase a storm and not put myself in any danger. That being said, I would never consider doing it, by myself or with anyone else if I didn't think I could handle myself in that situation.
