We all know too well that there’s no perfect weather prediction system. But some sources are better than others, especially when it comes to smartphone apps. While most commercial weather services draw free data from the National Weather Service, the best employ computer algorithms and teams of meteorologists to interpret the data and create their own forecasts.
Among the few apps that do have teams, algorithms, and NWS data, however, the difference is more a matter of design and use than accuracy. “My experience has shown that there’s not a lot of difference between them,” says Jon Nese, a senior lecturer in meteorology at Penn State University. The following six apps each have the best data, but a slightly different method of interpreting and displaying it, so there’s a right one for every type of weather watcher.
