The Met Office has issued a yellow warning for the Yorkshire and Humber area with possible thunderstorms at the start of the week.
Despite the showers during Saturday night, high temperatures are set to stay but on Tuesday and Wednesday the office has said some northwestern areas of the UK could come under a much increased risk of seeing thunderstorms or longer spells of thundery rain, with some torrential downpours in places.
The Met Office said: “The public should be aware of the risk of localised disruption to travel, and more generally to summer holiday activities, with a chance of surface water flooding.
“An area of low pressure is expected to increasingly interact with the plume of hot, humid air resident across parts of southern Britain.
“Whilst preceding days will have seen relatively isolated thunderstorms, the developing set-up on Tuesday and Wednesday, provides the ingredients for more widespread and energetic storms.
“Large rainfall totals, falling in short periods (perhaps exceeding 50mm in three hours) and onto hard-baked ground, may lead to flooding locally, with hail and gusty winds an additional possibility.
“As is common in such situations, not everywhere will catch the heaviest of the storms, and some places may well escape altogether.”
