le Pingouin, why only up to 10,000ft? They seemed to do just fine with Area Forecasts going a lot further up prior to this. I was told by someone from BOM that it was done so as to allow them to increase the frequency of TAFs being issued to which I've seen no difference in the year since it changed.
They obviously know what the actual freezing level is, so why not just put it there like they've always been able to?
