After September’s spectacular highs, the UK’s Indian summer looks certain to come to a crashing end this week. Netweather’s senior forecaster Nick Finnis said the unseasonably warm temperatures of around 3C (37F) above average for this time of year will end from Wednesday onwards.
After a fine start to the week “it will turn cooler later in the week with increasingly windy conditions taking over, with unsettled weather in the north, though staying mostly dry in the south,” he added.
Mr Finnis said the changes will be afoot from mid-week, “as high pressure retreats and allows a strong jet stream coming out of northern Canada across southern Greenland to slip down towards northern Britain”.
He added: “The jet stream will bring low pressure systems southeast close to Scotland, tightening isobars across the UK, bringing cooler and windy conditions for the second half of the week, with gales likely in the north – along with spells of rain or showers.”
This “strong jet stream ploughing across Scotland” on Wednesday night will herald in “windier and unsettled conditions for the north” in the second half of this week.

This will weaken “as it arrives across northern England in the evening” where brighter and cooler conditions are expected.
Unfortunately for Scots, the torrid conditions look set to remain with gales possible across the country on Thursday morning.
This will result in a “windy and cool day with showers in the morning across the north merging into a longer spell of rain” across much of Scotland.
Further south will escape much of this wet and windy weather – remaining mostly dry and bright.
Moving into Friday the country is set to be hit by a “brisk westerly wind which will bring scattered showers in the west, mostly dry and bright in the east”, Netweather reported.
BBC Weather’s long range forecast is predicting a similar outlook.
It said: “The weather is expected to change to a more unsettled pattern with low pressure barging in by midweek and bringing wetter, cooler, and windier weather for much of the UK.
“This pattern looks like it will become locked in place for the first half of October at least, keeping things wet and unsettled.
“Temperatures are likely to be changeable day-to-day as weather fronts move through, but there is potential for some colder air to linger a bit longer at times.
“Chances of more settled weather are decreasing, and it looks like autumn is here to stay.”
