UK hot weather maps show exactly when balmy 22C Caribbean plume will blast Britain

Parts of the UK are expected to bask in an Indian Summer that actually originates in the Caribbean early next month.

After areas were belted with record rain fall, people in the south of the country can expect things to warm up before winter, according to weather prediction charts.

October 9 is set to be the warmest with up to 22C predicted by Netweather.tv.

The Met Office's definition of an Indian summer is unseasonably warm temperatures spiking in October and November months.

Netweather.tv.s chart for the day shows warmer temperatures from France impacting upon East Anglia and the south east, with counties south of London peaking at 21 or 22C.

The same chart for October 8 shows a warm band with temperatures above 20C from the south west up through the Midlands, with slightly lower temperatures in the south east and East Anglia.

The "Indian summer" will start with slightly reduced temperature from

Weather maps show the warmth originating in the Caribbean and heading towards us across Iberia.

WXCHARTS' weather maps, aided by Metdesk data, shows jet streams bringing warmer aid from the Caribbean straight to the UK.

This warmer air will make its way to the UK on Sunday, October 6 at speeds of around 130mph, it predicts.

While the mornings will still have temperatures in single digits, by midday the UK could see temperatures in the high teens in the southeast.

Unfortunately, it will only be a brief respite, peaking on October 9, with the Met Office warning that more miserable conditions will be on the horizon later in October.

Its forecast for September 28 to October 7 says that the last weekend of September will be settled before "cloud and patchy rain will probably quite quickly spread into the northwest, and is increasingly likely elsewhere by Sunday."

The first week of October will have settled spells but there will also be "spells of rain, heavy in places, with a risk of strong winds."

The forecasted added: "A more settled spell is possible, but less likely. Temperatures are likely to be near to or below normal throughout, and it is likely to be notably cold at the start of this period, before temperatures recover."

Between October 7 and October 21, there will be a mix of wet and windy weather "interspersed with some spells of calmer, drier weather. Temperatures will most likely be close to normal", the Met Office said.

Netweather.tv's long-range forecast adds: "Although there is inevitably a fair amount of uncertainty at this range, it is looking probable that this period will be wetter than average for most of the UK, with low pressure systems and some heavy falls of rain associated with frontal systems and south-westerly winds.

"Some colder outbreaks of polar air are likely to continue to affect the north at times, particularly the north of Scotland, while the south will often be in warm tropical maritime air."

Today:

Scotland will be hit by showery rain, which will extend to parts of northern England later and could be heavy at times. The rest of the UK can expect a brighter, though fresher day than Monday, with a few showers developing.

Tonight:

Rain and showers will largely die out across the northeast, although showers will continue along the coasts. It will be cloudy elsewhere and cool in sheltered spots.

Wednesday:

The south will be cloudy and mild, but rain will reach the southwest during the late morning, spreading eastwards across much of England and Wales by the end of the day.

Outlook for Thursday to Saturday:

Most areas will experience wet and potentially windy weather on Thursday. Northern Scotland should remain drier and colder.

A showery, blustery and chilly northerly airstream is expected for all on Friday.
