I agree with PP and others on this, MetOff data and forecasting is pretty accurate upto 24/48 hrs, you just need to interprete it and not expect it to be minute by minute or exactly correct where you're standing. Maybe use it in conjunction with XCweather(wind), MWIS (mountains), weatheline (lakes) SAIS (scottish Avalanche info, if you're scottish winter walking). Maybe also look at Metoff forecasts for nearby areas to get a better general view. They can't be absolute, by the minute or exactly where you are standing at any given moment, but they can give a good indication of what to expect throughout a day. All the other worthwhile forecasts use the metoff, anything else (ie Metcheck, accuweather)is not worth looking at IMO.
