TEMPERATURES are set to soar to 21C in an "Indian summer" TOMORROW after Britain was battered by flash floods and rain.
Storms will give way to a plume of warm air from the Continent dragged in by the remains of Hurricane Sam.
Temperatures in parts of the country could hit 21C on Thursday as high pressure builds across Europe into the UK.
Much of Britain will bask in a balmy blast of sunshine and blue skies although parts of the northwest will stay wet and windy.
Jim Dale, meteorologist for British Weather Services, said: “The warmer weather will kick in from mid-week onwards, and we could see 21C in parts of the country by Thursday.
“High pressure building from the Continent will bring a change from the wetter, windier weather to drier, sunnier conditions.
“As we are now in October, we can call this an Indian Summer, and it is safe to say we are in for some balmy weather in the fallout from Hurricane Sam.”
North East Scotland and England will be warmer than southern Britain – with highs of around 21C.
London and the South East could creep towards the 20C mark with above-average temperatures forecast nationwide.
Sam weakened from a Category 4 hurricane to a strong storm as it charged across the Atlantic at the weekend.
It will bump into the jet stream as it approaches Europe and veer towards Iceland helping to drive the fine weather.
Mr Dale said: “The remains of Hurricane Sam will veer towards Iceland as it moves across the Atlantic, this will mean it will miss the UK but pull warm air in from the south.
“It will also drive this region of high pressure across Britain, the combination of the two will bring the better weather.
“This could last through the week or possibly longer into the mid-month when we expect to see a return to something more usual for the time of year.”
Exacta Weather forecaster James Madden said: “In between the stormier spells some quite mild weather will develop.
“It could turn out to be a warmer than average month overall.”
North western regions may catch Sam’s stormier sting in the tail while the rest of the country bakes.
Parts of Scotland and Northern Ireland are battening the hatches for more wind and rain ahead of the weekend.
A Met Office spokesman said: “Rain, heavy and persistent at times, will affect parts of Scotland and Northern Ireland.
“It will be dry elsewhere with variable cloud, sunny spells and overnight fog patches.
It will be warmer than of late.”
In fact, temperatures in Britain will be higher than in Monaco, on the French Riviera, expected to peak at 19C or 20C this week.
It comes as London was plunged into travel chaos after an inch of rain pummelled the city in just an hour with streets completely flooded today.
Flash flooding has caused havoc on several tube lines and roads in the capital have been submerged underwater as drains were quickly overwhelmed by the downpour.
Footage also shows heavy flooding on the A4 in London, and TfL have warned of more danger on the A3, A41 and A12.
Buses and other cars can also be seen in videos struggling to move through the floodwater in Knightsbridge, while part of the M25 is also flooded.
The circle and district lines are both partly suspended due to a signal failure caused by flooding at Gloucester Road, according to the TfL website.
Transport for London are advising that tickets will be accepted on London buses.
The metropolitan line is also experiencing minor delays due to flooding near Aldgate.
London Overground is also part suspended with no service between Willesden Junction and Clapham Junction, due to flooding in the Imperial Wharf area.
