The models keep on improving. In the 1990s they finally got to the point where theory managed to predict the weather of the entire globe for a month one year. Now by 'predict' they meant it rained when and where they expected it to and was about the right temperature. Their grid size was several miles on a side, so it was more difficult to model mountains, buildings and such. Computing power has grown a lot since then, and so has the accuracy. It cracks me up all the complaining about weather forecasting. You can see the improvement in forecasting accuracy in just the last 14 years. And yet people complain likes its the dark ages of meteorology. On Tues, some people in NYC were up in arms because the 3' snow monster that had been forecasted turned out to be 10" monster. Of course, what happened is that they didn't pay attention and so didn't understand that there were several computer models not all of which were predicting the 3' snowfall; that it depended how close the storm hugged the coast. As it turned out the storm stayed further from the coast, so that Long Island got 2' and Boston got the 3'. To me, the improved accuracy in weather forecasting is pretty dramatic.
