I have been working on a new Model a model that combines the best of Geographical information Systems (GIS) and the GFS and the other models for forecasting for the Washington Dc metro area it has the topographic maps of the US Geological Survey and the best of the models used in weather Forecasting the Canadian and the ECMWF and the GFS and the NAM the best of all of those models its called the
Geographical Weather Forecast System or GWFS its been designed to take in to account the Geographical differnces between Washington Dc and places like Rockville Maryland Rockville is higher in elevation that Washington DC is and so is the eastern shore and lower central maryland it takes that into acct and can forecast winter storms with fairly acurate relyablity maybe 85 to 95% of the time it can but it sometimes goes back to its GFS Roots and underperforms but thats because its a GFS based model blend of all the other models out there and the GFS.
anyway the model was developed by me it took a year to develop and it took another year of in operational testing to make shure it was ready to go to National weather service offices through out the country and hopefully it will help improve Forecasting in all the areas its in operation 2014 is the first year its in full operation and so far its had a decent sucess rate with winter storms from time to time it goes back to its GFS roots but thats ok no numerical model is perfect so yeah the rest is complicated technical stuff.
