Temperatures are predicted to drop to as low as -10 degrees tonight (Saturday) in some parts of the country as a 100-mile "ice corridor" descends over England and Scotland.
The Met Office have issued a yellow warning - meaning be aware, for snow and ice across many parts of the country including West Berkshire.
The warning which was first put into effect this afternoon will continue until 10am tomorrow morning (Sunday).
Forecaster's are predicting outbreaks of snow and icy road conditions, and are warning of possible travel disruption.
The chief forecaster's assessment reads: "A frontal zone which moved eastwards into Britain on Saturday has stalling [sic] against the cold airmass which became established over the UK earlier in the week.
"This has allowed 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 continue 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, icy stretches are likely on [sic] to develop on untreated surfaces, including footpaths and cycleways, as snow starts to peter out later on Saturday evening or during Saturday night."
