After a cool and wet start to June, temperatures are set to rise again by the end of this week – although there is uncertainty about just how warm it will get.
With high pressure building it will turn drier and sunnier for most areas of the UK.
Parts of England and Wales are likely to see highs in the mid-twenties Celsius, with Scotland and Northern Ireland getting into the low-twenties.
Some computer models suggest it could get a little warmer than that but it is too early to say whether it will be warm enough for long enough for an official heatwave to be declared.
Before the weather settles down for the end of the week, more heavy rain and thunderstorms are in the forecast.
On Wednesday heavy showers are expected across the UK with a high chance of some of these being thundery in eastern Scotland and eastern England.
It will feel cool for the time of year again with temperatures around 3 to 6C below average.
Lower temperatures will persist into Thursday as a large area of rain moves in from the west across many parts of the UK.
While it will get drier, brighter and slightly warmer on Friday, it is the weekend when high pressure gradually builds in from the south, turning things drier.
It could turn significantly warmer too – depending on what shape that area of high pressure takes.
