A recent survey found that most adults check the forecast 4 times a day. But, how much do you really know about weather forecasts? This True/False test will help you find out:

  • First: True or False: The weather’s getting harder to predict. That’s True. A Princeton University study found that in the last 20 years, weather variations have gotten more extreme. And since forecasts are based on past conditions that are similar, those fluctuations make it more difficult to accurately predict what will happen. 

  • Next: “Partly cloudy” and “partly sunny” mean two different things. That’s False. Both terms mean that between 30 and 60–percent of the sky will be covered by clouds. 

  • Another True/False weather question: You shouldn’t trust predictions beyond 3 days in the future. True. After 72 hours, a weather prediction’s margin for error doubles. And that’s especially true for snow. Because depending on the temperature, the moisture from an inch of rain can become between 4 and 25 inches of snow! 

  • Okay: True or False: Every weathercaster on TV is a trained meteorologist. Not necessarily. Some stations choose forecasters for their on-air presence – and simply have them read the local forecast from the National Weather Service.

  • And the final True-False question: Weather watchers will have to do without predictions for the entire year of 2017. Maybe. The current crop of weather-watching satellites is nearing the end of their useful life. And most are expected to stop working in 2017. Or about 12 months before their replacement satellites are scheduled for launch.
