Actually, its the turmoil that's gone before today, and it helps you predict tomorrow's weather. Though like all forecasts, you can't predict too far ahead.
The idea behind "yesterday's weather" is that you can either 1) spend a huge amount of effort trying to measure enverything in the world, then grind away with some enormous numerical model (e.g. the Met Office, CoCoMo), or else 2) predict that today will be like yesterday and get about the same level of accuracy. Both methods fall apart when attempting to predict next week's weather.
This turns out to be a difficult metaphor to deploy in the tropics, where a child could predict the weather pretty accurately ("hot and sunny with a slight chance of stupendous thunder storms") arbitrarily far into the future. --KeithB
