Outbreaks of sleet and snow will spread from the northwest on Saturday affecting parts of Merseyside, according to the Met Office.
Temperatures dropped on Friday night to freezing which brought cold ICY conditions to the region.
The cold conditions will continue throughout Saturday as daytime temperatures will struggle to reach over 3C and any precipitation that reaches the region could turn to snow.
The Met Office warning is in place until 6am Sunday as 1-3 cm snowfall is possible in places across Merseyside.

A forecaster at the Met Office said: “A frontal zone moving eastwards into Britain on Saturday will run into and stall against the cold airmass which became established over the UK earlier in the week.
“This allows rain at the leading edge of this frontal zone to turn to snow and persist for several hours before the frontal zone weakens during Sunday, allowing less cold conditions to start developing and some of the snow to start melting.
“This snow is expected to fall along a relatively narrow corridor, perhaps only 100 miles wide, which means that some areas within the warning area may escape much of the snow.
“Meanwhile, where snow is limited or rain occurs instead, icy stretches may develop on untreated roads as rain and snow starts”.
