The term weather is often used to describe the conditions of the atmosphere over a short period of time. In contrast, climate is a more general description of the average conditions over a longer period of time. Many factors affect weather, including temperature, humidity, wind speed, cloud cover, and precipitation. The cause of all weather is the sun. Different land and water surfaces absorb the sun's rays differently, causing variations in overlying air masses.
There are several apps that allow you to view weather forecasts. The National Hurricane Center offers detailed information about storms in the Atlantic and the East Pacific, which you may find useful for preparing for a storm. ReadyTN provides weather data in a user-friendly data viewer. Other apps include the Appy Weather, Dark Sky, and Flux. While these are all good options, these three apps are largely lacking in features. Still, Flux is the clear winner when it comes to aesthetics.
One of the most popular apps for weather data is Weather Up. It's free to download, but features a prominent ad on the home screen. For $1.99 a month or $9.99 a year, you can access more weather data and see animations. Its premium version is also free. Unlike the free version, the pro version offers a plethora of extra features. It has a few different modes, including the ability to set alerts for severe weather.
