I generally use metcheck.com
Its pretty damn accurate in the 3 hour intervals it gives you - just remember to check your route too if doing a long ride - cos last year we got soaked on one trip, cos I didnt check 2 of the counties in the middle part & blithely assumed it was all going to be cloudy but dry
I use the 8 - 14 day one as a guide, but it isnt always that reliable cos the wind will flaming change direction, or speed up, or slow down
