It could be the middle of July before Tayside and Fife enjoy a return to summer, it has been warned.
The UK has suffered one of the wettest Junes on record and Met Office experts do not expect significant improvements until next week.
The freak conditions are being blamed on a jet stream which has remained over the south of the UK, trapping low pressure and unsettled weather across much of the UK.
Many parts of the UK have suffered extreme flooding while even Dundee, which has been spared the worst of the weather, has endured the wettest June in living memory.
According to the James Hutton Institute in Invergowrie, 141.1mm of rain fell in June. This is more than 5.5 inches and the highest level of rainfall for the month since records began in 1954.
In fact, on June 21 alone 47.7mm nearly two inches of rain fell. This is nearly the normal amount of rainfall expected over the entire month, rather than in one single day.
Anyone hoping for a sudden end to the sodden summer will be disappointed as forecasters say the jet stream responsible for the damp weather will continue to wreak havoc for at least another week or two.
The jet stream is a fast-moving channel of wind that is caused when cold air from the north meets warmer air from the south. The resultant jet stream forms about six miles above the surface of the Earth.
As the wind corridor picks up speed, it sucks up air from below and forces it up through this atmosphere. This creates areas of low pressure below the jet stream which creates unsettled weather conditions.
The jet stream is constantly moving, but normally it travels over the north and west of Scotland during the summer months.
This means although these areas may endure rainier summers, other parts of the country can generally count on drier days as areas of low pressure are being directed away from the UK .
This year, however, the jet stream has become lodged over the south of England, in a similar position to where it would normally be found in winter.
Its southerly direction means the low pressure areas which cause heavy rain are passing straight over the UK.
In fact, the only part of the country not to be enduring a wet and miserable summer is the north west of Scotland, which usually gets stuck with the worst of the summer weather.
Forecasters may be able to explain why the summer has been so poor but they are less certain when it will come to an end.
A spokesman for the Met Office said the poor weather will continue until at least the weekend bad news for the tens of thousands due to attend T in the Park at Balado.
”There will still be a changeable and unsettled picture, although there will be some points of sun and gentle improvement,” he said. ”The better weather will really come in at the end of the month, but there will be some improvements over the next two or three weeks.”
Last week the fierce storms caused weather warnings to be issues across much of the UK, including Tayside and Fife.
Thousands of homes were evacuated while a man drowned after being swept away in a Shropshire stream. Northern England, the Midlands and Northern Ireland endured the worst of the weather.
