I have answered these questions in a new piece on my blog entitled "The Secrets of Weather Forecast Models, Exposed." I'll quote briefly below, please read the entire piece.

Some of the most frequently asked questions from blog readers and Forum users are as follows:

"Why are the models so inaccurate?"
"Who is providing oversight for improvements to the models?"
"Is the GFS model really worse than the ECMWF?"

If you search for "computer weather forecast model accuracy" on Google, you won't find much. But I am here today to answer these questions for you based on some knowledge that I've picked up over the last few years. Here are the facts as I see them:

- The models are inaccurate due to a number of factors
- The U.S. Government (NOAA) and educational institutions monitor the accuracy of models
- The models are routinely tweaked by NOAA to increase accuracy
- The U.S. GFS model is less accurate than the European ECMWF model
- NOAA believes it may have found why and is working to change the GFS
