As humans we like to know about simple facts. As with weather forecasts we like to know exactly what temperature it’s going to be, if the sun will be shining or it’s going to be rain and sometimes also about the wind speed and direction relating to a given place and time in the future.
Meteorologists have struggled for ages to tell us about that. A traditional weather forecast will tell us the best guess for these few key indicators.
Many people today, including me, don’t really rely on the weather to do our work. But we may plan when to work, how to get to work and what to do besides work depending on the weather forecast.
So I usually study the weather forecast. Lately I have noticed that the Danish Meteorological Institute has experimented with how to visualize to the common people that the weather forecast is a best guess. So for example instead of having single colored blue plies indicating how much rain to expect, they now have the choice to have blue piles in different light or darker blue colors indicating the risk (or chance if you like) of rain.
Better data quality? I think so. Less confusing? I think not. It could be rain anytime. But it probably won’t.
