We can only forecast the weather a few days into the future

We needed a statistic for this? I thought it was common knowledge, kind of like water is wet, fire is hot, (weather) predictions are getting more inaccurate the longer time scale they are predicting...

Did you know that they're really only accurate a few days out? Despite the fact that most weather sites provide forecasts a week or two out.

Yes. You didn't? Because frankly I feel they get really inaccurate just two days out. No idea why there's 10 day forecasts. If you look at them every day you'll notice that 10 day forecasts change every day.

Different post. :-) That post was about the accuracy/reliability of various weather forecasting services for predicting rain.

This one is about the accuracy of three weather forecasting methods and how far into the future they can predict the temperature.

Yes, my mistake, you're absolutely right. They're different articles.

But they are talking about the same problem, giving related data, posted the same day, and clearly related. So I think the cross-reference is valid, and the discussion on the other submission is appropriate.

But it's true that they are definitely different articles.

Sure! That's valid. Just didn't want people to get confused. It's happened before. :-)
