This is why a thick fog has descended on Leeds and this is how long it will last
Leeds is currently covered in a thick layer of fog, with it set to continue overnight. But what has caused it and when will it clear?
The Met Office explain that fog is caused by tiny water droplets suspended in the air, with the thickest fogs tending to occur in industrial areas where there are many pollution particles on which water droplets can grow.
According to the Met Office, “Fog is essentially a cloud at ground level that causes a reduction in visibility to less than 1000 m.
“However, for most people, thick fog is when visibility drops below 180 m. Severe disruption to transport occurs when the visibility falls below 50 m over a wide area. This is referred to as dense fog.”
When will it clear?
Leeds will see largely cloudy conditions tonight that will persist overnight with patchy drizzle in places, and misty conditions across the hills. There will generally be light winds, with a minimum temperature of 3 °C.
Tonight, the UK in general will see “Outbreaks of rain, heavy at times, spreading into far western parts. Largely cloudy elsewhere though some frost and mist patches forming under clear spells in the far east.”
However, tomorrow in Leeds is set to be “Largely cloudy but mostly dry at first, but a better chance of some brighter spells developing through the afternoon as winds freshen,” said the Met Office.
Thursday in Yorkshire will then be “rather cloudy but mostly dry, although occasional coastal showers.
“A brisk, colder wind. Friday, probably brighter with lighter winds. Cold. Saturday, rain with hill snow, moving east. Strong winds.”
