Arctic plunge set to send us an August chill

It’s not an easy task being a weatherman when summer fails to deliver an acceptable amount of sunshine and warmth to our shores.

June was duller and wetter than normal, with some parts of England, Wales and eastern Scotland having double their average rainfall.

July was drier than normal in the places that had a soaking June, but temperatures have been nothing special, with any notable heat lasting no more than a few days.

View from a hillside country road of hills beneath dark storm clouds. Monks road above the village of Charlesworth in Derbyshire. View towards Manchester on the horizon.

August began on a wet note, with many southern parts of England and Wales having more rain in a day than they saw through the whole of dry July.

You get the picture… Summer this year hasn’t been great, which means that news of a plunge of Arctic air across the UK and much of Europe next week will not be welcome.

Arctic plunge

Whilst temperatures will pick up a little this weekend – especially across England and Wales – next week will see them fall significantly towards Wednesday and Thursday.

Once again, our weather friend and foe, the jet stream, is wiggling around quite a bit during the next week.

Having moved from west to east during the first few days of August, the jet stream will meander quite far north towards Iceland, before diving southwards over the UK in the middle of next week.

This will open the gates to a plunge of chilly Arctic air diving southwards across not only us, but also much of Europe.

August chill next week

Daytime temperatures across much of Europe – including the UK – will be 5-10C below average, with Sunrises over the rural landscape of the Clyde Valley.some spots 15C below normal.

Next Thursday will see daytime temperatures reaching just 12-17C across England and Wales, with 9-14C across Scotland and Northern Ireland.

At night, temperatures will widely fall into single figures, with a good chance of seeing a touch of frost in rural areas in the north of the UK.

What about the rest of August?

The cool weather will last a few days, before temperatures start to pick up to closer to normal during the weekend after next.

After spotting some rainclouds over St Ives Bay from our holiday apartment, I headed down to Carbis Bay beach. Rainbows kept appearing and disappearing as a number of showers crossed the bay from the west (left). This was one of the more vivid and persistent (double) rainbows.However, looking further ahead towards the rest of August, the changeable weather looks set to continue, with little prospect of any prolonged spells of sunshine or notable warmth.

Some newspapers still seem to be going on about a heatwave, but they’ve been saying that all summer and nothing has happened so far. Read into that what you will…

Don’t forget, you can get the latest forecast on the Channel 4 Weather website. I’ll also be posting regular updates on Twitter – @liamdutton

    Thank you Liam, very useful for my tender plants to see the satellite jet stream weather map rather than all these rumours about a heat wave

  2. Someone says:

    How accurate is this based off this ‘Climatology’ from 2010?

  3. David Mitchell says:

    For those of us who simply can’t cope with hot temperatures, the prospect of some lovely cool, fresh, clean Arctic air is most welcome. A few inches of rain for my parched garden would be the icing on the cake.

    It’s not really anything out of the ordinary though Scotland has certainly seen gales which have veered to the northwest today bringing in some chilly air for the time of year! But I appreciate that this prediction was made four days ago rather than closer to the event.

    “Daytime temperatures across much of Europe – including the UK – will be 5-10C below average, with some spots 15C below normal.” Sorry – not happening in the UK at least (maybe in Scandinavia?). The Liam tweet of 10 August confirms around 5 C below average. Cool but not abnormally so.

    Essex hot and dry since June. Not a drop of rain. What planet…?

    I have to say that I live in East Anglia and run a small tea room, to be honest your weather predictions are well below the grade, you said today would see the East and especially east Anglia seeing heavy down poors ect ect , hardly a drop has fallen around Great Yarmouth, this is easterly and in East Anglia, I did not open toady along with other small business owners because of you rubbish weather forecast.

    I enjoy the Channel 4 news, most informative but I have to say I have seen better weather forecasts come out of a fortune cookie.

    If you are happy with the way you present your weather forecast then I bet you never sleep at night, how channel for continue to pay your salary beggers belief.

    hang you clouds up mate and don some shades because you are better off digging sand castles on a beach far far away looking up at the sky and thinking about your old job.

    terrible, worse than Michael Fish, sorry but you have cost me more than one days business this year.
