The Met Office has said that there could be scattered showers and thunderstorms could develop on Monday afternoon in northwest England, the southwest and Scotland.
Tuesday will see similar conditions, with sunny periods for most areas and isolated afternoon showers.
Those heaviest and with the risk of thunderstorms in southern and western Northern Ireland. Temperatures will be up a few degrees on Monday’s, with maxima of 25°C in southern England.
By Wednesday, there’s the potential for more organised rain or showers across parts of southern England and Wales, with the odd thunderstorm possible. Other areas will continue to enjoy predominantly fine weather.
Thursday and Friday bring plenty of sunshine, particularly in western areas, while eastern regions remain cloudier.
Temperatures will reach the high teens to low 20 degrees Celsius during daytime hours, although eastern coastal areas will remain chilly.
We could have some unseasonably cold nights on Thursday and Friday, with some isolated frost possible.
Deputy Chief Meteorologist Mark Sidaway said, “The high pressure that has been around for the last few weeks will slowly lose its grip on the UK this week, bringing a change to more unsettled conditions with many areas seeing rain or showers, ending the prolonged dry spell.
“The change comes this weekend, with weather systems moving in from the Atlantic, arriving from the west probably later on Friday and through Saturday.
“They will bring with them spells of rain, which may be heavy at times, with a risk of strong winds in places.
“These conditions will gradually spread across the UK on Saturday, with Sunday and Bank Holiday Monday likely seeing sunshine and showers.
“So, whilst the bank holiday won’t be a complete washout, with some sunshine expected, this weekend represents a notable shift from the fine and settled weather pattern that has dominated so far this month.”
