I finally tracked down this table of rules and terminology to describe temperature in weather forecasts. I knew I had read it, but for the life of me couldn’t think in what publication. As you can see it was published in 1956 by the Meteorological Office in a very interesting publication called the “Weather Map” so not just quite as old as I am. If you remember I am on a impossible crusade to get all weather presenters to obey the same kind of terminology to describe temperature when presenting their weather forecasts on TV and radio.
