Downpours to continue for UK with risk of flash flooding

Heavy rainfall and thunderstorms will persist across much of the United Kingdom on Thursday, posing a risk of flash flooding and road congestion. The Met Office has issued a yellow thunderstorm warning for northern England and north Wales, which remains in effect until 10:00 BST. As the downpours move south and east, they could impact additional regions of Wales, the Midlands, East Anglia, and southern England.

Travelers should be cautious of slippery road surfaces and the possibility of flooded roads. Temperatures are expected to decrease, with some areas remaining colder than the August average. Rainfall amounts may vary, with some locations experiencing up to 30-50mm of rain in a six-hour period, enough to trigger flash flooding in areas where the ground remains hard from a recent heatwave.

Motorists are advised to drive cautiously and maintain a safe distance from other vehicles. Despite the return of wet weather, the prolonged drought affecting much of the UK is not expected to end immediately. A sustained period of heavy rainfall would be necessary to replenish water supplies, a situation unlikely to be determined until late winter.

However, it is worth noting that some regions have received above-average rainfall this summer, with Aultbea in the Scottish Highlands recording 389.6mm - more than one and a half times the seasonal average. As northerly winds strengthen, temperatures are projected to fall, with Thursday's high of 13-23C being the first day since June 29 when no location in the UK reached 25C.

Friday is expected to be even cooler, with temperatures remaining below the August average. Overnight lows in parts of Scotland and northern England could dip below 4C, bringing a prolonged period of cold weather. Over the weekend, temperatures are expected to gradually rise, though daytime highs will still be below the seasonal norm.
