I've given up on the Met Office forecasts. They are an utter waste of time. I use the Norwegian site now - they seem to at lest have half a clue about what they're doing!

It's been the online forecast site of choice of the Friday Night Riders for a few years now and it's usually quite accurate.
The BBC weather site is another which is pretty good.
