Ok so we can talk all day about TAFs & Metars specifics but the fact remains the met office is getting it basically wrong too often.
eg;
As a broad picture yesterday they indicated a fine day in the south east for today. This morning, a whole 18 hrs later they now have rain showers spreading across the region later today !
No wonder most people ( general public ) seem to think the metoffice is doing a poor job compared to a few years ago.
