The UK forecasts are actually from the NMM models we run, but Nick is right in that all forecast models can be wrong at times. That said, looking at the data from yesterday afternoon it actually quite closely matches the actuals from weather stations in the midlands and was showing 21-22c with broken cloud as far as I can see. So if you were seeing something different, please can you email us (here) with info on the postcode/town you were using as it may be a location error. Also, are you definitely using the UK forecasts and not the world forecasts, as the UK ones use the NMM which is much higher-resolution. http://www.netweather.tv/index.cgi?action=uk7dayx2;sess=
