I check it every day, and it's been fairly pessimistic until suddenly, this afternoon, they must have seen evidence to replace their previous forecast model with this new offering:
UK Outlook for Wednesday 23 May 2012 to Friday 1 Jun 2012:
By the middle of next week much of the UK is likely to be dry with some sunshine, although eastern and southeastern areas may well be cloudy with outbreaks of rain at first. These mainly settled conditions seem likely to continue for the rest of May and into the start of June with a good deal of dry sunny weather likely. There are some indications that cloud and rain could spread into some western and southwestern areas towards the end of the month though. Temperatures look likely to be above average or warm in most places, and may become very warm locally. Eastern coasts may remain relatively cool though where easterly or northeasterly winds persist.
