In 1960, I had recently joined the RAF full time and we were having a meteorological lesson. The instructor had planned the weather perfectly. It poured with rain, the sun came out. "Now what is this?" We chorussed "Cold Front."
Today - embarrassingly I hadn't checked the weather before going shopping - I bored my wife (who is tolerant but to be honest, not that excited by weather phenomena) with : "This must be a cold front, just like my Met lesson 60 years ago."
