If you're heading out today, make sure you take extra care,
A yellow weather warning for fog has been issued for Yorkshire and the Humber for today - although the skies over some areas of Grimsby, including Scartho - are clear and blue this morning.
The Met Office said: "There will be areas of dense fog developing during Saturday night, becoming more widespread around dawn on Sunday, before thinning slowly during the morning.
"The worst affected areas are likely to be low lying regions where the visibility may reduce to less than 100 metres in places, leading to difficult driving conditions and some disruption to travel.
"Showers will fade away during Saturday evening, with clear skies and light winds a recipe for fog development. "Some patches may persist until late morning, particularly across the Midlands and northern England."
