The Met Office today urged people in Oxfordshire to “be prepared” as severe weather looked set to sweep across the region.

Forecasters warned road and rail could be affected tomorrow if its predicted snowfall hits.

Conditions should only last 24 hours, with Saturday and Sunday predicted to be sunny and cold, with the chance of rain on Monday.

Temperatures are expected to drop to -4C over the next few days, with highs of 5C in the day.

A Met Office spokesman said: “There is a high risk of severe weather affecting parts of east and south east England during Thursday evening and Friday.

“Heavy snow showers will give accumulations of 5-10cm in places on low ground and 15-20cm over hills. The snow showers are expected to gradually die out from the north of the area through the day.

“Some drifting snow is likely in the strong north to north-easterly wind. This could cause disruption to travel networks.”

She added the chances of a white Christmas are still “hanging in the balance” and forecasters will know more by Monday.
