It is the run up to Halloween and Britain is in for some wacky weather, with warm temperatures giving way to 'blood rain' and even the chance of some snow as temperatures plunge by as much as 10 degrees in less than a week.

And if the rain clears, stargazers will be treated to a meteor shower on Monday just before dawn, with the debris from Halley's Comet sending a cascade of shooting stars across the night sky.

The best time to see the meteors was on Sunday morning, but there may still be a chance to catch the shower on Monday

Meanwhile 'Indian Summer' type conditions are forecast for the early part of this week with temperatures due to hit the high teens or even 20C, the Met Office has said.

Higher temperatures are expected across Britain early next week

"It's definitely going to be warmer than average, especially in parts of the south of Britain" Met Office forecaster Emma Sharples told the Huffington Post UK.

"It's not going-to-the-beach kind of weather, as there's expected to be an awful lot of cloud and drizzly conditions" she added.

Commenting on reports of 'blood rain', Ms Sharples said rain may be stained with dust drawn up from Africa's Sahara desert.

"That's where the warmer air has come from," she added.

Blood rain is so-called because of its reddish hue. When the rainwater evaporates it can often leave a red stain on cars.

On Thursday and Friday Arctic air is set to make Britain distinctly chillier, according to reports. A cold snap is likely to bring snow to Scotland and the north of England, reported the Telegraph.

Senior risk meteorologist Jim Dale from British Weather Services warned Britons to prepare for a chillier than average winter with a bleak prediction that "impressively cold temperatures" will blast parts of the UK.

He told the Huffington Post UK: "Although we don't expect a cold Armageddon or conditions as bad as the winter of 2010, Britain is not expected to have a mild winter."

Autumn has brought mixed weather conditions with floods and torrential rain in some parts giving rise to fine October sunshine.
