Meteorologist Rosie Mammatt (University of Reading) compared several apps over a two-week period for Which? (published last month).
The most accurate app was The Weather Channel. It performed well when forecasting the weather for the next few hours (known as a nowcast) and was also strong at predicting the weather accurately for later the same day. It offers free apps for both Android and Apple, and it’s available at weather.com. https://www.which.co.uk/news/article/we ... 43y6N3kuUN
