Met Office forecasts temperatures above average despite weather warnings in Wales. In the past few days, heavy downpours have been prevalent, leading to the issuance of a Met Office yellow weather warning for rain from Tuesday evening to Wednesday evening. However, the outlook for the upcoming week suggests a shift towards milder yet unsettled conditions, with intermittent heavy rain and strong gusts of wind expected, as per the Met Office.
This change is attributed to warm, damp air masses from western Europe, originating from the western Mediterranean and northwest Africa, reaching the UK with southerly breezes. This transition is forecasted to push temperatures above average levels despite cloudy skies. Met Office Chief Meteorologist, Matthew Lehnert, anticipates temperatures reaching mid to high teens across the UK, with southeast England potentially seeing temperatures of 20-21°C on Wednesday. Nonetheless, this warm and humid air mass brings the risk of heavy rain and isolated thunderstorms, prompting yellow national severe weather warnings for rain in parts of the UK.
In Wales, temperatures could peak at 15-17°C on Wednesday but may slightly decrease to around 15°C on Thursday. The latter part of the week is expected to maintain mild temperatures with recurring rain or showers, possibly accompanied by strong winds in the north and west by Friday. There is a probability of a deep low-pressure system from the Atlantic affecting the UK over the weekend, potentially leading to more widespread strong winds, particularly in northern and western regions.
As uncertainty looms over the exact strength and path of this system, Met Office Deputy Chief Meteorologist, Dan Holley, advises staying updated with the latest forecasts. Despite potential coastal impacts and disruptions, the overall outlook suggests mild temperatures continuing for this time of year. The public is encouraged to monitor weather updates closely to stay informed about any potential warnings or advisories.
