A long-range weather forecast by the BBC’s Monthly Outlook indicates that the UK can expect heavy downpours, strong winds and possible cyclone warnings being issued between September 6 and September 19. The forecast stated that September weather comes with the “general heavy caveat of hurricanes leading to a higher chance of disruption”. But this time, the UK is set to be trapped between high pressure building just north of Europe and the high pressure shifting around in the North Atlantic well to the country’s southwest.

This means that “these two areas of high pressure will tend to trap lows that are normally near Iceland over us instead,” the forecast said.

It added: “We anticipate a more unsettled month with wetter and generally cooler than normal weather.”

It continued: “Around mid-September, there is the greatest chance for a more progressive pattern to develop.

“This would see more westerly winds bringing Atlantic fronts in quicker and more frequently.

“This is still an unsettled pattern, but temperatures w.ill become much more changeable day-to-day and there is a better chance of higher winds at times.”

However, the forecast made it clear that the chances of that happening, as of now, are very low.

Despite the hurricane season making the extreme weather events more likely, there is only around a 35 percent chance of that developing.

In addition to that, the confidence in the forecast is very low due to the unpredictability of tropical cyclones at long range.

The Met Office added: “Confidence decreasing into this period, however, there is a signal for high pressure and associated settled conditions to gradually become less dominant, with a trend towards more unsettled conditions.

“This may bring changeable conditions with periods of showers and longer spells of rain, interspersed with drier spells at times.

“Temperatures are likely to be above average for the time of the year.”

The news comes after it was reported that the UK is set to sizzle in blistering heat from Portugal sending weather charts scorching red as the country prepares to be bathed in sunshine for at least 10 days.

Southeast England will likely see “normal temperatures”, but central and northern regions of the country could see temperatures “slightly to moderately above normal by a few degrees”.

AccuWeather meteorologist Alyssa Smithmyer told Express.co.uk: “A current look at how temperatures are faring with respect to what is average for this time of year is that most places across the United Kingdom are a few degrees above normal.

“There is currently an area of high pressure lingering over the United Kingdom, which is allowing for largely fine and settled weather.

“This feature can also contribute to warmer air across the region since this warm air mass travelled northward from the west coast of Portugal and originated from much warmer regions.

“This area of high pressure will linger throughout this week but will eventually adapt to the relatively cooler northern air and lose its warm influence.”

Ms Smithmyer added: As we look at the next few weeks, however, the general pattern as we shift through this last week of August and into the month of September is that much of southern England will see temperatures close to what is average for this time of year, perhaps a few select days hovering a few degrees slightly above the average daily temperature.

“But the pattern for areas, including London, look to remain close to normal.

“In reference to that, ‘normal’ temperatures across London for the last week of August hover around 68-69 degrees F (20-20.6C) typically.

“Normal temperatures by the last week in September are expected to slowly lower to be around 62-64 degrees F (16.7-17.8C).

“As we look at the pattern set up for central England and northern regions of the United Kingdom, however, it points to slightly warmer than normal temperatures being recorded for the next few weeks.”

The Weather Outlook has also forecast a chance of it being slightly warmer in the south of the country.

The Weather Outlook said: “At this stage close to average temperatures are favoured during the August Bank Holiday weekend, although there is a chance of it being warm in the south.

“A good deal of dry weather is probable in southern and eastern counties, but the risk of rain is greater in the north and west.”
