It seems to me that we are trying to make it easier for "newbies" off the street to get a handle on what a forecast means. If this is so, then they are learning a new set of meanings to words any way, so why not learn the ICAO codes which the non English speaking world can also use? What hardship is there in learning what a set of codes means instead of what a set of words means? Something new must be assimilated into the grey matter, so why not the ICAO codes?
