WeatherGraph is a simple but powerful weather app for iPhone, iPad, and Apple Watch that provides weather forecasts in the United States. It utilizes data from the National Weather Service (NWS) and presents it in an easy-to-read graphical format. Developed by Jackson Myers, WeatherGraph offers high-quality weather data that is used by academic researchers and meteorologists.

With WeatherGraph, you can access 24 hours of observations and 7 days of forecasts for your chosen locations. The app also allows you to view record highs and lows for each weather station you follow. Additionally, WeatherGraph offers a Today View Widget, which displays a graph of upcoming weather conditions, and an Apple Watch app with a complication that shows the highs and lows as well as the rain probability for the next 2 days.

It is important to note that WeatherGraph exclusively provides weather forecasts for the United States of America, as all data is sourced directly from the NWS/NOAA. This free app is a valuable tool for anyone looking for accurate and visually appealing weather forecasts within the United States.
