Remember 2013?
Long-range forecasts are garbage. It's "weather entertainment"... something to talk about just for the sake of having something to talk about. Tuesday night is the *earliest* they can get reasonably close on a weekend forecast. It is scientifically impossible to make an accurate long-range forecast, due to chaos theory. There are an infinite number of variables involved, and tiniest change in the initial constraints multiplies exponentially over time. Meteorologists guess right now and then, so people still pay attention to them. LOL
That being said, we've all seen them get it wrong in real time, too, which is pretty impressive!
Best of luck to everyone!
