Fireworks fans may need to huddle a little closer to the bonfire on Saturday night, with temperatures expected to dip to freezing across parts of the UK.
Forecasters have predicted a chilly weekend, with the risk of snow in pockets of Scotland on Bonfire Night.
Areas blessed with clear skies and bright sunshine during the day will see the temperatures drop, while icy winds are expected to ravage parts of the coastline.
Met Office spokesman Grahame Madge said: “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.
“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.
“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.”
He said the highest figures during the day would be around London (11C / 52F), before the temperatures drop going into the evening.
He said: “Most places will be in single digits, possibly down to zero or even minus one in places that have clear skies.”
