Probability in Weather Forecasting

Should You Bring an Umbrella?

Meteorologists use probability to predict the weather! When you hear there's a 70% chance of rain, that means that in similar situations, it rained 7 out of 10 times.

How Forecasts Work

  • Use past data and computer models to estimate probabilities.
  • Combine information like humidity, temperature, and wind to predict outcomes.

Probability helps you decide what to wear, when to travel, and how to plan your day.

Examples

  • Deciding to bring a raincoat when there's a 40% chance of rain.

  • Planning a picnic when the forecast says there's only a 10% chance of thunderstorms.
