Motorists are being warned to take care on the roads after a fog warning was issued for the west of Suffolk for this evening.
The Met Office's yellow alert affects the area around Bury St Edmunds, Newmarket and Mildenhall and includes a stretch of the A14.
It is in place from 7pm on Friday to 11am the following day.
During this time, visibility may be impaired and bus and rail services could also be delayed.
A separate fog warning, which covered the whole of Suffolk, was issued by the Met Office earlier this week.
Suffolk police issued a warning to drivers following a number of weather-related collisions in the county, including a car crashing into a pond near Eye.
The weather is expecting to remain cold this weekend, according to East Anglian forecasters Weatherquest.
Meteorologist Fred Best said: "Saturday is going to be a cloudy and murky day, perhaps a bit more extensive than in the last few days.
"Temperatures could be chilly, with highs of 5C or 6C, maybe even 7C locally."
