The responsibility for weather forecasting lies primarily with meteorologists. They are the professionals who study the atmosphere, analyze meteorological data, and make predictions about upcoming weather conditions. These meteorologists work in various organizations such as government weather agencies, research institutions, universities, and private weather companies.

To get weather forecasts, there are several sources you can refer to:

1. National Weather Service (NWS): In the United States, the NWS is responsible for providing accurate weather forecasts and warnings. Their forecasts can be accessed through their website, mobile apps, or by tuning in to local NWS radio stations.

2. Weather Websites and Apps: There are numerous websites and mobile applications that provide weather forecasts. Some popular options include Weather.com, AccuWeather, and The Weather Channel. These services utilize meteorological data to create forecasts tailored to specific locations.

3. TV and Radio Stations: Many television and radio stations have their own meteorologists who provide regular weather updates. You can tune in to your local stations for the latest forecasts.

4. Mobile Notifications: Some weather apps offer the option to receive push notifications for severe weather alerts or daily forecasts. These notifications can keep you informed without actively checking the weather app.

Remember, weather forecasts are not 100% accurate and can vary in accuracy depending on the time frame and location. It's always a good idea to check multiple sources for a more reliable and comprehensive understanding of the weather.
