UK weather forecast: Rare heat system brings Indian Summer – temperatures to nudge 20C


A powerful jet stream over the North Atlantic will blast low pressure towards the UK. The jet stream is so strong due to cold air from Canada and northern US tracking towards Britain. This cold air will contrast with warmer than average sea surface temperatures over the northwestern Atlantic. Forecasters have predicted this could lead to dry and warm weather in southern England by Halloween.

Met Office forecaster Grahame Madge forecast temperatures to edge closer to 20C next week.

He told “Next week will be what meteorologists call a very mobile set up as a disruptive system from the Atlantic weather will impact the UK from tomorrow.

“It will be mild for this time of year as warmer air will hit further south.

“Average temperatures next week will be 17C at the most on Tuesday, with London seeing highs of 15C during the week.

“At the end of October, temperatures in the UK will average 13C.”

Mr Madge added forecasters were also watching the post-tropical lifecycle of Hurricane Epsilon as it is expected to merge with a trough and combine into a powerful non-tropical storm in the North Atlantic.

Storm Epsilon will push a deep low pressure towards the UK next week, potentially bringing heavy rain and gales.

However, Mr Madge added the storm, which is currently located near Bermuda, is still too far out to tell whether it will hit the UK.

The forecast said: “Unsettled conditions are expected to dominate during the period, with most parts of the UK seeing plenty of cloud and outbreaks of rain and showers.

“It will often be windy, with a risk of gales or even severe gales, especially in coastal areas.

“However, some brief bright and dry spells are still likely at times in all parts of the UK, with the most settled conditions probably found across eastern and south-eastern areas.

“Overall, temperatures are generally looking to be close to normal for the time of year. Conditions may turn more settled close to the end of the period, particularly in the south.”

Netweather’s long-range forecast for the end of October also predicted warmer temperatures in the south east of England.

It said: “Later in the week it will generally turn warmer than average with a stronger tropical maritime influence, meaning that dull damp weather will be common over and to the west of high ground.

“But the south and east of England and sheltered parts of eastern Scotland will see some sunshine coming through at times.

“Mean temperatures will be very close to the 1981-2010 long-term normal during this week, but up to a degree above in the south-east and about 1C below in Northern Ireland.”
