On average, the accuracy differences between various services are higher for temperature than precipitation. Overall, the hardest states to predict the weather in are North Dakota and Montana, where apps are only right about 64 percent of the time. Likewise, temperature forecasts are strongest in Florida. In California, apps predicted rain (or more likely, no rain) in some areas with more than 97 percent accuracy in 2015. Places like Florida, California and Alaska are easier to forecast with high accuracy. "The Plains states are notoriously difficult to predict because you're constantly having fronts battle it out." "There is wide variation in the ability of forecast models to make accurate predictions in different areas," said Eric Floehr, the founder of ForecastAdvisor. Areas near the coasts or other bodies of water are often easier to forecast than inland areas. The business of predicting the weather can be far more challenging in some parts of the country than others. That's in line with another analysis that found that AccuWeather is the most accurate temperature forecaster globally.
The Weather Channel and Weather Underground are again at the top of the stack nationwide for forecasting high temperatures, but AccuWeather far surpasses all rivals in its ability to predict low temperatures to within three degrees. If you're in Los Angeles and worried about rain, stick with Dark Sky. So the best app depends mostly on where you are: If you're in Miami, MeteoGroup is best overall. The two apps came out as the most accurate options for predicting rain in a little over 60 percent of weather stations, which means that one of the other apps we looked at is still best in the other 40 percent. (The two apps sometimes give different results based on how a user's location is interpreted, but the underlying source is identical, the company said.) When it comes to predicting whether it will rain one to three days ahead of time in 2015, Weather Underground and The Weather Channel have the highest average accuracy across the country at almost 84 percent.
