As of December 22nd, 2022, the old FAA Thunderstorms publication (AC 00-24C) is canceled. The content of that advisory circular (AC) has been absorbed (with 5 other FAA weather publications) and updated into the new FAA Aviation Weather Handbook (free PDF here).
See an example of the updated imagery in the new weather handbook (FAA-H-8083-28), versus the line drawings from the earlier AC 00-24B from 1983 (move the slider left and right):
FAA-H-8083-28 really is the ultimate FAA aviation weather handbook with all the FAA weather content in one book – pick up a paper copy here or get the free digital PDF here.
Full disclosure – some of the links will provide a small commission to Helicopter Training Videos at no extra cost to you.
