UK climate maps present actual time Icelandic wall of rain will hit for ’34 days’

A massive rainstorm is set to sweep across the UK from Iceland, putting an end to our scorching summer.

This week alone, parts of the country will be hit with rainfall equivalent to an average August’s total, including 20mm – nearly half of the typical monthly total – in just a few hours, across north Wales on Thursday morning (August 15).

Heavy rain is also forecasted for Northwest England, including Merseyside and Greater Manchester, from today going into Thursday morning. The low-pressure system will then move eastwards, with Humberside and Lincolnshire expected to face the worst of it in the afternoon.

The rain, moving swiftly from Iceland and across the North Atlantic, will reach Scotland by this evening, bringing thunderstorms in places.

Overnight, the band of rain will expand and intensify, reaching as far west as Northern Ireland and as far east as the Scottish Borders before heading south.

According to the Met Office, the UK typically sees an average of 53mm of rain in August, which works out at around 1.7mm each day. However, more than 20mm is expected to fall in north Wales in just a few hours on Thursday morning.

This essentially equates to 34 days’ worth of rain, based on the daily average, reports the Mirror.

This sudden deluge will bring a stark end to the recent glorious weather. On Monday (August 12), the hottest day of the year so far, temperatures soared to 34.8C in Cambridge, 33C in Holbeach, Lincolnshire, and 33.5C in Wisley, Surrey.

However, the Met Office had predicted much cooler temperatures of around 20C for many today.

Parts of Wales, Lancashire and Merseyside have already been lashed by heavy downpours today, with conditions expected to worsen overnight across Northwest England as the topsy-turvy weather continues. Ventusky forecasters predict this band of rain, separate to the Icelandic barrage, will move across the Midlands overnight.

Brits will have to swap their summer wardrobes for knitwear as temperatures plummet with highs of just 23C forecast in Norwich, a stark contrast to the 34C scorcher recorded on Monday. Even before tomorrow’s downpours, temperatures are expected to struggle to reach the teens for many.

The Met Office’s website reads: “Drizzle in the south will gradually ease through Wednesday but it will stay cloudy and cool, with fog around some coasts. Dry elsewhere with some sunny spells.”

However, there is some light at the end of the tunnel, with the Met Office predicting drier conditions towards the end of the week with some showers and strong winds.

The site reads: “A spell of wet and windy weather moves through on Thursday. Drier towards the end of the week with some showers and strong winds at times in the north.”
