Temperatures are set to plunge again midway through this week, with a chance of sleet and snow falling in York and North Yorkshire.
The Met Office said we are set for a widespread chilly spell. In York temperatures are forecast to be as low as -3C overnight.
Greg Dewhurst, meteorologist at the Met Office, said: “Overall, it is generally a cold week to come – frost and fog are the main features initially.
“Then there is potential for some rain and some hill snow as we move through the latter part of Wednesday into Thursday.”
An area of low pressure moving in from the south west on Thursday could meet colder air and create rain across southern England and Wales which could turn to snow over higher ground.
There will also be a risk of some wintry showers in the northern half of the UK with the potential for hill snow, with temperatures below average.
The forecast for York and North Yorkshire includes a prediction for sleet falling on Friday (1 December).
