UK weather: hazardous driving conditions as fog warning issued by Met Office

On Friday morning, dense fog has settled across various regions of the United Kingdom, raising concerns about potentially dangerous driving conditions. The Met Office has responded by issuing a yellow severe weather warning, covering areas from Lincolnshire and the East Midlands through the Home Counties and extending into parts of Greater London. Visibility in affected locations could drop below 100 metres intermittently, posing a significant hazard especially during the busy morning commute.

The fog is expected to gradually dissipate and lift as the morning progresses, although it may linger longer in some rural eastern areas, possibly not clearing until later in the afternoon. Motorists are advised to exercise caution during these conditions due to limited visibility. Despite the disruption caused by fog, weather conditions are anticipated to improve through the day as the fog thins out.

Looking ahead to the weekend, early Saturday may see lingering mist and patches of fog that could develop into low cloud, persisting throughout much of the day in some places. However, many areas will enjoy dry spells with occasional sunshine. An exception to the otherwise settled picture will be north-west Scotland, where a weak weather front is expected to bring cloudier skies and periods of rain. Temperatures will remain close to average, mirroring recent days.

By Sunday, that weakening weather front will shift, bringing more cloud to Wales and central England with the possibility of light rain or drizzle, though precipitation amounts are expected to be minimal. The remainder of the UK should experience a largely dry day with variable cloud and some sunny intervals. This outlook is underpinned by a high-pressure system building over the UK, marking a noticeable change from the stormier conditions seen last week when powerful Atlantic jet stream currents generated a series of storms.

This high pressure looks set to dominate the weather for at least the next ten days due to a “diffluent blocking pattern” forming in the jet stream over the UK and western Europe. This pattern will act as a barrier, preventing new weather systems from reaching the area. While a few pockets of low cloud and drizzle might still occur, overall rainfall is expected to be minimal.

With no storms expected imminently, the arrival of Storm Chloe—the next named storm on this season’s list—appears unlikely in the short term. Meanwhile, drought remains a pressing concern, as 82% of England is currently classified as drought-affected according to the Environment Agency. Although recent storms brought some short-term relief, more sustained rainfall is necessary to replenish rivers, reservoirs, and groundwater.

Following a recent National Drought Group meeting, water companies have been urged to accelerate efforts to repair leaks, while the public is encouraged to conserve water by taking shorter showers and turning off taps while brushing teeth. Philip Duffy, Chief Executive of the Environment Agency, emphasized, “The recent rain is welcome, but the drought isn’t over. A few wet days cannot reverse months of hot, dry weather. Our rivers, reservoirs and groundwater need sustained rainfall to recover, and the effects on nature can last much longer.”

Looking toward the coming months, the Met Office has noted that the ongoing El Niño pattern could increase the likelihood of wetter and stormier conditions in late autumn and early winter, with forecasts indicating double the chance of above-average rainfall during this period
