The UK could experience the coldest Bonfire Night of the century as fireworks displays are cancelled and lockdown in England starts.
A -3C 1,000 mile-wide ‘Greenland cold bubble’ is set to hit, making temperatures chillier than in Russia.
Frosty -3C lows are due on Thursday morning which could reach -1C by the night, with the south expected to be the coldest.
England’s first snow of the winter has fallen in Yorkshire and gritters are on duty.
Below average highs of just 9-11C are forecast in England tomorrow, making it colder than 12C Kaliningrad, Russia.
A maximum temperature below 11.2C would make it the coldest November 5 for at least 20 years, since 2000.
Bookmakers Ladbrokes have cutthe odds on the coldest November 5 of this century to 3/1.
Ladbrokes spokesman Alex Apati said: “Fireworks are going up but temperatures are coming down.”
The chill is expected to ease by the weekend – but worse cold spells are due in an “early winter” later this month, ex-BBC and Met Office forecaster John Hammond of weathertrending said.
He said: “After cold nights, frost and chilly days – and winter is likely to appear early later in the month.”
The Weather Outlook forecaster Brian Gaze said: “The coldest Bonfire Night of recent years is possible.
“-3C on Thursday morning and -1C on Thursday night is expected in the South. Wrap up warm for garden fireworks.”
Met Office forecaster Marco Petagna added: “The chilly north to north-westerly airstream is a shock after such mild weather recently.”
A Met Office forecaster said: “It will slowly turn milder from Friday to Sunday.”
