The UK faces a dramatic weather shift as tropical storm remnants disrupt the North Sea, jolting the jet stream and steering low-pressure systems towards Britain.
Met Office meteorologist Kathryn Chalk said: "It is going to be turning changeable as we go through the week, with another system coming through during the early hours of Wednesday across Northern Ireland.
"This band of rain then edges into Wales, the southwest of England and into northern England and Scotland as we head into the afternoon, and this rain could be heavy with the odd rumble of thunder, flash of lightning and hail."
“Temperatures will fall closer to average, down to 21C or 22C.”
Chalk warned: "As we go into Wednesday night and into Thursday, that system pushes its way in from the west, and it is going to be a rather unsettled start towards the far southeast with brighter spells behind that.
"As we go into Friday, we have another system moving through, and there will be some gusty winds, and if it is rainfall you are after, the southeast is where you are more likely to be impacted by some heavy showers or perhaps even some thunder."
Jim Dale, meteorologist for British Weather Services, added: "The western flank of the country will get the heaviest downpours as the gates to the Atlantic open allowing low pressure to move across the UK bringing unsettled spells of weather.
"Towards the middle of the week, there will be a risk of thunder as cooler air comes into contact with the warmer air left over the country after the bank holiday."
