Whither weather?

I am really getting fed up with the poor quality of weather forecasts. I believe that they are actually getting worse.
I use BBC online for 5 days of local weather. Quite often it is 100% wrong - even on the day.
For example, on one recent day it forecast 'dry' at the same time as I was looking out of the window at a major deluge.
On other occasions, the weather just three days ahead may change as much as three times in the runup to the actual day.

And to think the 'experts' claim to be able to predict 'warming' umpteen years ahead!
