In reply to Indy:
I stopped watching and trusting BBC weather forecasts roughly 10 years ago as I was fed up with its negative forecasts predicting doom, gloom and disaster.
I regularly held off on trips away on the advice of the BBC Warnings while my mates ignored this advice. They always returned with stories of perfect weather and photos to back this all up.
In the end I put my trust in Accuweather and have never regretted this decision once.
How come Accueweather can predict weather changes with a couple of hours accuracy and the BBC can't?
We British, and I say this as a generalisation, think that all our State Run services like the Meteorological Office are the best in the world, without knowing or realising that there are alternatives to gauge them by.
I'm betting that many on this site, who own a smartphone or tablet have at least one Weather App on it. How many of those apps are not powered by the MET Office I wonder?
