Here's a thing I don't understand. Let's say the forecast for today has minimum temperature -10 and maximum -5. Then tomorrow the forecast has minimum -3 and maximum -1 (it doesn't, by the way, before you all get the sun screen out). How does that work? What happens at midnight? How does it go from -5 to -3 in the blink of an eye?
Also, how come, if today's minimum temperature is -5, it is currently -10?
