The weather forecasts in the UK are definitely much better than they were a decade ago, especially in the 3 to 14 day range. However, I still find my stupid heuristic works quite well for predicting tomorrow's weather: the weather tomorrow will be the same as what it was today. The UK often gets sticky ("blocking") weather patterns, so it works surprisingly well.
