I've been dabbling with skew T for a few months. I know it is useful for cloud tops and for understanding the atmospheric thermodynamics, but other than those two aspects, what is useful that is not already available from aviationweather.gov? Cloud bases, winds & temperature aloft and convective & icing potential are already covered by other products. Are LCL, LFC and CAPE numbers really that useful for flying? I guess my main question is, if it is so useful why is it not part of aviationweather.gov? It is not discussed in the FAA's aviation weather handbook, nor is it covered in any of the pilot training syllabi.
