**Met Office Issues Thunderstorm Warning as Hefty Showers Approach Wales**
Wales is bracing for a spell of unsettled weather on Wednesday, 21 May, as the Met Office has issued a warning for thunderstorms and heavy downpours across much of the region, particularly affecting southern areas. This announcement comes as meteorologists anticipate a dynamic weather pattern, with bursts of rain interrupted by occasional sunshine.
Forecasters have outlined that Wednesday will begin with overcast skies and significant rainfall, especially across southern parts of the country. Prolonged periods of precipitation are expected, bringing the possibility of localised flooding and disruption to travel. The inclement weather, however, is not set to last throughout the day, with breaks in the clouds allowing for some sunny intervals.
According to the Met Office, these brighter spells could be punctuated by sharp, thundery showers as the day wears on. The meteorological service predicts temperatures could reach up to 22°C, creating muggy and unsettled conditions in affected regions. Many communities will need to keep umbrellas at the ready, as the mixture of rain and sunshine adds to the unpredictable spring weather.
Residents are advised to remain vigilant throughout the afternoon, as the heaviest showers carry the risk of thunder and lightning. The Met Office has highlighted that while rainfall will be most intense in the south, all parts of Wales may experience some downpours. Areas under darkening skies should be mindful of possible changes to outdoor plans, with sporadic sunshine occasionally peeking through.
By the evening, conditions are expected to calm, with showers gradually subsiding to leave clearer skies overnight. Temperatures are forecast to drop significantly, with the potential for rural areas to experience low temperatures around 2°C. Light winds are predicted to contribute to a chilly night, and some localities could wake up to patches of mist and fog on Thursday morning.
Looking ahead to Thursday, forecasters are predicting a much more settled day. Early fog and mist should quickly dissipate, making way for bright and warm spells of sunshine. There remains a slight chance of isolated light showers in the afternoon, but most places will stay dry. The air will feel fresher, and temperatures are anticipated to peak at 19°C, offering some relief after the stormy interlude.
The outlook for the remainder of the week shows continued changeability in the region’s weather. Friday is set to start on a crisp note, with drier and sunnier conditions likely through the day. However, cloud is forecast to build up from the west as the weekend approaches, bringing further outbreaks of rain into Saturday. This will clear to leave scattered showers and brief sunny periods for Sunday.
With this in mind, the Met Office continues to encourage locals and visitors alike to monitor updates regularly. Those travelling or enjoying outdoor activities should stay informed about the latest weather advisories to minimise the risk of any disruption or inconvenience.
Wales’ characteristic volatility in spring weather serves as a reminder of the need to remain adaptable. While periods of rain and thunderstorms may be inconvenient, the brief sunny intervals offer moments of respite and highlight the region’s transitioning seasons. As always, preparedness is key for navigating the changeable British climate.
