I had a name for metcheck when I was at uni, I called it metcheque because of its disputable value for money.
If I had access to a weather station I could have a go at verifying the accuracy of the forecasts and determine the forecasting skill and could do it with a number of other freely available forecasting products that are out there to determine which is the best. I know for a fact that forecasts found in newspapers can be pretty spot on, they are provided by the Meteogroup which is run out of an office at the Press Association.
As for forecasts I use. I use my own, all done by interpreting expert charts provided by a couple of different models that are available freely on the internet.
