UK Weather Alert: Dense Fog to Cause Hazardous Driving Conditions

Dense fog is expected to create hazardous driving conditions across parts of the United Kingdom starting Sunday and continuing into the following week. England and Wales are most likely to experience the fog on Sunday, with the risk then shifting northward.

The Met Office issued a yellow weather warning for areas of England and Wales early Saturday morning, predicting visibility on roads could fall to less than 100 meters in some locations. Further warnings may be issued as the low angle of the late autumn sun means mist and fog patches are slow to dissipate.

On Sunday morning, the Midlands, eastern Wales, and eastern England are most at risk of encountering dense fog. Some patchy mist and fog may also form in other regions. A weak weather front is forecast to bring cloud and light drizzle to southern Scotland, northern England, and the far north of Wales, potentially reducing fog in these areas initially.

Scotland and Northern Ireland are expected to see brighter weather with spells of autumn sunshine, apart from the occasional shower.

Fog Risk Shifts Northward

From Monday onwards, high pressure is expected to remain the dominant weather system, leading to a northward shift in fog risks. Clear overnight skies and light winds will allow mist and fog patches to form readily, exacerbated by cooler nights. As the high pressure moves towards the North Sea, winds in the south of the UK are expected to shift direction and strengthen.

The period between Monday and Friday is anticipated to bring little change in overall weather patterns. Areas most prone to dense morning fog include the Scottish glens, the Central Belt, the Cheshire Plains, the Vale of York, and parts of Northern Ireland. However, mist and fog patches cannot be ruled out elsewhere.

Travel disruption is possible as fog patches may be slow to clear in some areas. While the UK is expected to remain largely dry under high pressure, an east or northeast wind could bring a few showers to eastern and southern coastal counties.

Daytime temperatures are predicted to remain close to average for early November, ranging from 11C in the north to 14C in the south. However, prolonged fog and low cloud could make some locations feel noticeably cooler. Overnight lows are expected to be between 2C and 3C in the north, and around 5C to 8C further south.

This largely settled and dry weather pattern is expected to continue into early November, with little prospect of significant rainfall.
