I am posting from the panhandle of Florida. It always seems that the forecasted temperatures for ECMWF is about 5-10 degrees Fahrenheit below the GFS forecasts and the actual temps of that day. For instance, tomorrow it is forecast by ECMWF to get up to 66 degrees Fahrenheit and 76 by GFS. Without a doubt it will be closer to 76. What could explain this disparity?
