The UK is expected to be hit by an "Arctic blast" over the coming days as the Met Office predict areas - including Oxfordshire - could see temperatures plunge below 10C.

Despite "unseasonably warm air" last weekend in which temperatures soared beyond 20C, it seems a typically cold Autumn has finally arrived.

Cold, northerly Arctic winds will push the mercury (temperature) down into single figures, the Met Office has said.

Heavy downpours, together with strong winds, are set to batter most of England until 8 pm tonight. Motorists are urged to take extra care while driving due to a build-up of surface water on the roads.

Met Office forecast for Oxfordshire:

Flood warnings are also in place for Oxfordshire.

Tonight:

Showery rain will move southeastwards, clearing into the channel this evening. Then staying dry as cool and clear conditions are established. Turning chilly with overnight temperatures falling to single figures. Minimum temperature 8 °C.

Saturday:

A sunny but chilly start. Cloud building to give an afternoon of bright spells interspersed with occasional showers. Showers fading and skies clearing later. Noticeably cooler than of late. Maximum temperature 14 °C.

Outlook for Sunday to Tuesday:

Turning brighter, fresher, and chillier through the period, with good spells of autumn sunshine. Largely settled, with the odd shower. Overnight fog and frost possible, especially in rural spots.

Sky News weather producer, Joanna Robinson, said it will be noticeably colder than recently. She said: "Expect a fairly widespread ground frost on Saturday night, with a rural air frost in places.

"A frosty Monday morning start"

"Sunday will be similar, but with fewer showers around."

"Despite the sunshine, temperatures aren't going to rise particularly high. In fact, for some of us they could be a little bit lower than Saturday," Alex Burkill from the Met Office added.

"In the south, you're looking at highs of 12C or 13C and some places in the north are likely to stay in single figures."

But Monday morning will bring a rude awakening for the new week.

The meteorologist added: "First thing Monday morning, you will really notice it - you may need to scrape your windscreen on your cars because it is going to be a chilly, perhaps even frosty start."
