I found met a bit of a dirge as well. As others have said, it's no good trying to learn it by rote; you have to understand it as well. Once you understand it it becomes a lot easier to understand.....

I still look at a 215 though; nod with knowledge as I read it then put it back no wiser than when I picked it up. I understand the text bit with the cloud and vis but those wavy lines on the map are just wavy lines on the map. I kind of get what's happening but there are guys at our club who can look at the lines and say 'Yeah, it will rain from 1412 to 1526 and then there will be an outbreak of tornadoes.'
As Billy Connoly said 'I don't need weather forecasters, if I want to know what the weather's like I look out the f****** window.'
Edit: I know when the wavy lines are close together it's windy and when they're not it's not.
