We now display the estimated certainty in our 7 day forecast as coloured bar, to indicate possible uncertain or frequently changing forecasts. The predictability considers uncertainties in pressure, precipitation, temperature, wind, larger scale patterns and climate inconsistencies.
We achieve a high and constant predictability in high pressure areas and locations with low weather variance (like deserts). Predictability is lower in low pressure situations, with intense precipitation events or thunderstorms. Our goal is to show you that some weather events are not so easy to predict and that some forecasts might be inaccurate or completely change within the next 12 hours. Your comments are appreciated.
