Why do weather forecasts sometimes fail to predict accurately?
In: Other
Aside from what others have said (and with the grain of salt that I’m in the U.S. and if you’re not the situation may different where you are), there are different models that produce different predictions. Some sources will use the prediction of the model they deem mostly likely to be accurate (I get my forecasts from NOAA for this reason -they’re wonderfully accurate [tho of course not perfect]). TV/radio stations, certain websites, basically anyone who’s making weather predictions as part of a money-making operation, are likely to use the predictions of the model that’s going to drive the most engagement. For example, I’m in Minnesota. We get a lot of snow in the winter (usually) and strong thunderstorms/tornadoes in the summer. Local TV forecasts are often much more dramatic – higher snow totals, stronger storms, more tornadoes – than I what I see on NOAA. Most oftern, the NOAA prediction is closer to what happens.
