New thunderstorm warnings for parts of UK as rain set to continue

The Met Office has issued new thunderstorm warnings for sections of the United Kingdom, forecasting continued wet weather through Thursday. The first warning kicks off at 02:00 BST, with thunder and heavy rain sweeping through southeastern England in the early hours. A second warning follows at 06:00 BST, covering a larger portion of England and Wales until 22:00.

Downpours might result in localized flash flooding and disrupt travel, with wetter regions potentially receiving up to 75mm (3 inches) of rain. Large hail, lightning, and strong winds could also accompany the showers, making it quite humid.

Thursday morning will begin wet in southern England and south Wales, with heavy downpours accompanied by lightning, hail, and squally winds. These will gradually move north, affecting mid and north Wales, the Midlands, and parts of eastern England. As the first line of downpours clears northwards, sunny intervals will emerge, but scattered, heavy, thundery showers remain possible. Northern Ireland and Scotland are expected to escape the heaviest rainfall, though they could still encounter considerable wet weather.

The Met Office cautions that 20-30mm (0.8-1.2 inches) of rain could fall within a few hours in the yellow warning area, with up to 50mm (2 inches) over a 12-hour span. Hills in the path of the easterly wind may accumulate up to 75mm (3 inches) of precipitation. Hazardous driving conditions are anticipated, potentially leading to road closures and isolated communities. Lightning strikes could cause power outages, and hailstones between 1-2 centimeters (0.4-0.8 inches) are also possible.

While the wet weather might bring relief to drought-stricken parts of England and Wales, the risk of flash flooding persists, particularly in areas with dry and compacted soil. However, these rain amounts are insufficient to alleviate the recent dry spell; experts warn that prolonged wet weather is necessary to replenish water supplies.

The upcoming weekend features several festivals and high-profile events, including the Reading and Leeds Festivals, Creamfields, Manchester Pride, and Notting Hill Carnival. The weather is expected to be mixed, featuring cooler temperatures, brisk winds, especially in the south, and intermittent rain. A wet weather system will advance eastwards across England and Wales on Saturday, though drier and sunnier conditions may develop in the west later.

Northern Ireland and Scotland will experience slightly drier weather, with occasional sunny spells, though isolated showers will still occur. Heavier showers will shift eastwards on Sunday, impacting most regions of the UK. Wind gusts may reach 40-45 mph (64-72 km/h) in the far south-west of England. Temperatures will vary from 16°C (61°F) in northern Scotland to 23°C (73°F) in southern England, which is typical for late August.

A low-pressure system remains in place, bringing strong winds and additional showers, particularly across the northern UK on Monday. A return to the dry, hot summer weather is not expected. For the most up-to-date forecast, consult the BBC Weather website and app.
