The UK is preparing for a weekend of significant weather changes, according to the Met Office. Forecasts indicate a period of heavy rainfall and unseasonably mild temperatures for many areas, before a sharp drop to colder conditions by Sunday. This shift could bring an increased risk of disruption, particularly from surface water flooding.
Saturday is expected to see the most substantial rainfall, with Met Office yellow warnings for rain currently in place for parts of the country. Specific regions in south-west England, Wales, and parts of Scotland are anticipated to experience prolonged periods of heavy downpours. Accompanying this rain will be mild air, pushing temperatures into the mid-teens, with some areas potentially reaching 15-16°C, which is well above the seasonal average for this time of year.
However, this mild, wet spell will be short-lived. A colder air mass is predicted to move across the UK from Sunday onwards, causing temperatures to fall noticeably. This change will bring a return to more typical winter conditions, with the potential for overnight frosts and even some wintry showers over higher ground, particularly in Scotland and northern England. Wind speeds could also increase, making the perceived temperature feel even colder.
Regional breakdowns show varying impacts. In England, the south-west is expected to bear the brunt of Saturday's rain, while the north and east may see slightly drier, but still mild, conditions before the cold snap. Wales is also forecast for heavy rain on Saturday, which could lead to localised flooding. Scotland will experience heavy rain, especially in western areas, before the colder air brings a risk of snow on higher ground. Northern Ireland will likely see a mix of rain and milder temperatures on Saturday, transitioning to colder, brighter conditions on Sunday.
Given the forecast for heavy rain, the Met Office advises the public to be aware of potential hazards. Motorists should exercise caution due to challenging driving conditions caused by surface water and reduced visibility. Residents in areas prone to flooding are encouraged to check local flood alerts and prepare accordingly. It is also wise to ensure gutters and drains are clear to help manage rainwater runoff.
