People going out out Bonfire Night are advised to wrap up warm, with a sudden cold snap expected to bring snow and frost to parts of Britain. Temperatures are expected to dip below freezing across much of the country, brought about clear skies and bright sunshine in the day.

A Met Office spokesman said: "On areas where there are showers and clear skies, there is a risk of some frost and there might be a bit of snow in Scotland."

"The general picture for Saturday is that it is going to be dry with some sunshine and showers – possibly heavy in the north of England and Scotland," said Grahame Madge. "It's going to be cold everywhere and chilly in the north and east of England, accentuated by the wind, with a risk of some gales."

According to ITV meteorologist Lucy Verasamy, partygoers should "expect the ground to be soggy and muddy in fields and parks" following yesterday's rain. However, on "Bonfire Night itself, it'll be clearer with much better visibility for the displays", but people will "need hats, gloves, scarves – the works."

She added: "It might be tricky to light some bonfires after Friday's rain and the blustery breeze picking up. But once the fire gets going, you might want to shuffle a little closer to keep warm!"

And according to the Met Office, human activity on Bonfire Night "can have an effect on the weather we experience the following day" though the scale of that effect does depend on the strength of the wind.

"Fresh winds will help clear the smoke particles and improve the visibility. However, calmer conditions with lighter winds means there is a greater chance of smoke remaining in the air, which can also help mist or fog develop – called smog."
