Live Weather Forecast Apps
Frog Weather Shortcut is a cost-free lifestyle application that gives you instant access to the current and upcoming weather forecasts right from your home screen. This allows you to decide whether you want to go for a walk or just relax inside. You can also track rain and snow in real time. The NOWRADAR map displays areas of current precipitation while the Yesterday's Radar Loop and Forecast Radar maps give you an idea of where the next areas of rain or snow are expected to be.
The AccuWeather app breaks down forecasts by the minute, so you know exactly when it will start and stop raining. This can be very helpful, especially if you're going to run into the rain, as it will tell you how long it will last before the rain starts to fall. The app is so good that Apple actually acquired it and is slowly integrating its functionality into the iOS weather app.
Another option is the Overdrop weather app, which is free with ads and has a pro tier available for those who want to get rid of the ads. It has a playful yet simple interface and several widgets that have different aesthetics and data sources. It can even create persistent notifications that show the latest weather information in your notification tray.
