I have to agree. Leaving aside the actual forecast accuracy, the BBC's on-line weather output is very frequently inconsistent on the same page (not to mention the far-too-frequent typos). I've lost count of the number of times the text summary for, in my case, London and SE England has said something like "freshening SW winds later tonight", but the hourly breakdown shows a SE light breeze throughout! The frequency of these inconsistencies with very short-term stuff simply doesn't inspire confidence in anything else. I think the BBC also tries to inject too much detail accuracy in, for instance, precipitation % chance - especially when the % chance for each hour doesn't tally with when they show the rain falling; e.g. 25% chance of rain with light cloud, then, in the next hour, 18% chance of rain (i.e. less likely) but with light rain shown.
Only my second post and moaning already!
