How accurate are the long range forecasts?

Copied

There have been tremendous improvements in the accuracy of longer range forecasts over the past several years. A forecast for the 7th day today is as accurate as it was for the 4th or 5th day 10 years ago. Further, there is now skill in forecasting out through 15 days, something that was not possible a few years ago. Still, a forecast for the 15th day is not going to be as accurate as a forecast for tomorrow. The best advice would be to look for trends of the weather from days 11-15....that is, will it be warmer or colder, wet or dry.
