BBC monthly outlook
Monday 8 May—Sunday 14 May
All change please, all change.
Into the start of this week this pattern doesn't look to change, at least at first. High pressure will slowly wriggle around close to the UK through Monday, Tuesday and Wednesday with a predominantly dry picture, some sunny spells but often quite a lot of cloud - especially in the east. It's all change though towards the end of the week and with some rain on the way and I'm sure that will come as welcome news to gardeners and growers. The rain will push in from the south coast through Thursday and Friday with perhaps even some heavy and thundery bursts.
Monday 15 May—Sunday 21 May
More rain on the way!
During this time the weather is likely to stay more unsettled with outbreaks of rain and showers affecting all parts at times, but more especially in the northwest of the country. Once again the rain could be heavy at times with the continued risk of thunderstorms. With lower pressure it will be breezier across the UK than it has been recently, with temperatures around the seasonal norm. However, with the wind direction initially coming in from the south or southwest temperatures could for a time be a little warmer than average, especially in the southeast.
Monday 22 May—Sunday 4 June
High pressure returns?
As we head towards the end of May and the start of meteorological summer it looks like high pressure will once again become established within the vicinity of the UK. At this stage it looks like the high pressure will initially build from the south or east perhaps then moving to a more central position over the UK; however there is considerable uncertainty in this at this stage. With higher pressure in the southeast then it is likely to be drier than average here, but elsewhere rainfall is likely to be around average.
Next week
Looking further ahead towards June and the start of meteorological summer what will the weather have in store?
