UK weather: Maps show Caribbean heatwave heading to UK and Indian summer | Weather | News

The UK will be treated to some warmer days over the coming weeks as the last rays of sunshine appear before autumn and winter.

The weather has been inhospitable across much of the UK over the past few days, with the Met Office even having to issue a yellow weather warning in many areas and only rarely activating a yellow alert.

However, WXCHARTS weather maps, supported by Metdesk data, show that jet streams are bringing warmer air from the Caribbean directly to the UK. According to the maps, the warmer air will reach the UK on Sunday 6 October at a speed of around 210 km/h.

While temperatures will still be in the single digits in the morning, temperatures in the south-east of Great Britain could reach high teens by midday.

On Monday, October 7, it will be cooler and temperatures will reach just above 15 degrees. The situation will be similar on Tuesday, October 8, with temperatures in the mid-15 degree range, as the weather maps from WXCHARTS show.

While warmer weather brings some relief after this week's rain, the Met Office warns that even worse weather conditions are to come in October.

According to the service's weather forecast for September 28 to October 7, the last weekend of September will calm down before “clouds and isolated rain are likely to spread fairly quickly northwestward and become more likely elsewhere by Sunday.”

There will be variable rain showers in the first week of October, but there will also be “intermittent heavy rain with the risk of strong winds”.

The weather forecast continues: “A quieter period is possible but less likely. Temperatures are likely to be near or below normal throughout, and the start of this period is likely to be noticeably cold before temperatures recover.”

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

Netweather's meteorologists are looking ahead to October, when the warmer weather is usually referred to as Indian summer. The Met Office's definition of Indian summer is: unusually warm temperatures, peaking in the months of October and November.

Their long-term forecast continues: “While there is inevitably some uncertainty in this area, it is likely that this period will be wetter than average across most parts of the UK, with low pressure areas and some heavy rainfall associated with frontal systems and south-westerly winds.”

“Some colder outbreaks of polar air are likely to continue to affect the north, particularly northern Scotland, at times, while the south will be frequently exposed to warm tropical marine air.”
