What is most accurate weather forecast? ›

AccuWeather gathers the best and most comprehensive weather data to deliver forecasts with Superior Accuracy. Forecasts are pinpointed for every location on Earth and extend further ahead than any other source.

A weather forecast is made up of three steps: observation and analysis, extrapolation to determine the state of the atmosphere in the future, and estimation of specific variables. One method of qualitative extrapolation is to conclude the weather features will continue to travel in the same direction as they have been.

The study analyzed 120 million forecasts from over 1,000 locations globally over a four-year period ending December 31, 2018, and AccuWeather was found to be the clear winner as the most accurate provider of weather forecasts in temperature, precipitation and wind speed– a clean sweep of all categories -- for a 1-5 ...

Among the most precise ones are AccuWeather, The Weather Channel, and Weather Underground. CARROT Weather's customizable weather widgets look great and work seamlessly on device home screens and smart watches.

Some people have interpreted it to mean that it will rain 30% of the time, others that it will affect 30% of the area. If we think back to how the number is generated, using an ensemble, we see it isn't really either of those, but more like 30% of forecast simulations suggest it will rain.

20 to 30% chance isolated, meaning a few showers and storms possible on the radar. Scattered. 40 to 60% chance, meaning that there's a good chance for a. few showers and storms.

The Short Answer: A seven-day forecast can accurately predict the weather about 80 percent of the time and a five-day forecast can accurately predict the weather approximately 90 percent of the time. However, a 10-day—or longer—forecast is only right about half the time.

The Weather Channel and Weather Underground came top for low temperature predictions. Dark Sky came last in all these categories. In the UK, the BBC app has the most users, followed by the Met Office's.

Global models with worldwide weather forecasts

These models are all generally fairly accurate in predicting large scale patterns/features, but all will become less accurate through time. The ECMWF is generally considered to be the most accurate global model, with the US's GFS slightly behind.
