Here's Why Weather Forecasts Have Seemed So Inaccurate Lately.

Who says forecasts are less accurate?

Weather forecasts from official services like the National Weather Service (NWS) are highly accurate for short-term windows, but their reliability steadily drops the further out they look.

As it has been for a while now.

1 to 3 days out: Highly accurate (90% to 98%).

4 to 7 days out: Generally reliable (80% accurate).

10 days or more: Less reliable (roughly 50% accurate).

I don't believe any of that has changed much. But then again I don't have access to the raw data anymore.
