South West Hertfordshire is set to see freezing temperatures on Saturday as snow is forecast to fall.
The Met Office says very cold weather will make temperatures feel bitter tomorrow morning, with Watford, Hertsmere, Three Rivers, St Albans and Dacorum feeling like -5c.
It comes after the weather forecaster issued a weather warning for snow in Hertfordshire for Saturday, which is in place from 3am to 8pm.
Areas in South West Hertfordshire are set to see snow in the morning, the Met Office predicts.
People are already starting to ask if they can go sledging or play in the snow under current lockdown rules.
When the Department for Health was asked if people having snowball fights or sledging would be allowed, they told ITV: "It is against the law to meet socially with family or friends unless they are part of your household or support bubble.
"You can only leave your home to exercise, and not for the purpose of recreation or leisure (eg a picnic or a social meeting).
"This should be limited to once per day, and you should not travel outside your local area."
