Honestly Tim Vasquez’s book on the Skew-T was incredible for me. There are also resources if you google!Is there some resource that can teach me this thing? I've seen it a number of times and never understood it. All I see is a guy holding a pencil, who had a serious case of the shakes.
And of course one of the patron saints of talk weather Trey Greenwood (Convective Chronicles on YouTube) has an excellent series on it.
