Answer 1

Remember that weather prediction has continued to get better as years have gone on. When I was a kid (in the dark ages of the 1970s), the weather prediction was:

Tomorrow would right more than half the time. And prediction would be RAIN/SUN/FOG YES/NO and that was it.

The day after that would be right one in ten.

All days past that would be “Partly cloudy” – Not kidding.

And then in the later 1990s, suddenly everyone had very accurate 3 day forecasts – that were accurate. And the one week look ahead was right more than half the time.

Now a days, the weather prediction has gotten very good.
