How do meteorologists forecast weather 10+ days out?

198 views

Hell, one website I look at will forecast the weather 30 days out and they’re mostly accurate, even when they say it might rain 18 days from now.

Is it as simple as just plugging data into forecast modeling software and pressing SUBMIT? How does the software know that it’ll be Xº multiple weeks from now?

Short answer: they can’t. Anything beyond a 3-Day Forecast is 70% guesswork. Anything beyond a 5-Day is 100% guesswork. What you see beyond that 5-Day is a prediction based on statistical data.
