Well, a rare event in weather is a “normal” day. When meteorologists talk about a normal or average temperature for a day, you would think that we’re referring to a temperature that occurs quite often on that date but…that is not the case. In fact we should probably never refer to a temperature as normal or average but call it the median temperature instead. So what does that mean? A median temperature is one where 50% of the days will be colder than that temperature and 50% of the days will be warmer. Now, that’s sounds about normal!
