August warmth to be short lived

Paul Hudson | 14:25 UK time, Tuesday, 2 August 2011

The warm air that has greeted the start of August looks set to a blip in what is certain to be described come September as yet another disappointing, unsettled summer.

Highest temperatures will be in the Southeast of the UK, where 30C (86F) is likely in the next 24 hours, but the warmth will be felt further north too, with 27C possible in parts of Lincolnshire. It will come as no surprise though that the high temperatures are likely to trigger local thunderstorms.

This comes off the back of a disappointing July.

Dishforth in North Yorkshire measured 62mm of rain, well above the July average of 45mm. July was also cooler and cloudier than average.

Waddington in Lincolnshire reported rainfall close to average with 48mm of rain, compared with their average of 52mm. There were only 157 hours of sunshine, compared with the average of 190 hours.

Elsewhere, it was the coolest July at Dublin airport for 46 years. Across the UK, it was the coolest based on CET temperature data since the abysmal July of 2007.

Interestingly, according to Philip Eden's UK climate website, July was amongst the top 5% of most 'northeasterly' Julys in the last 139 years.

Looking ahead, a prolonged spell of settled warm weather, at least for the first half of August, looks highly unlikely. There is a strong signal from all the main forecasting centres that low pressure will dominate our weather at least until mid-month.

Indeed later this weekend and into next week, conditions may feel Autumnal at times with the potential for a deep area of low pressure to develop bringing wind and rain to most areas. The chart below is typical of what could lie in store.

    You'll need to get some 60w bulbs shining on them solar panels Paul; mind you you’ll probably still cash in on the FIT by doing that ;-)

    I am again surprised at the final CET figure for July, as I had thought it had been fairly warm on the whole. This seems to be due to relatively cool night time temperatures and more normal day time ones.
    The figure of 13.8c means it ranks as only the 255th warmest July out of 353 in the CET series and 0.5c below the median July temperature for the series.

    Oops, problems converting the data file to Excel.
    It's actually joint 253rd warmest and 0.7c below the median.
    The same average temperature as 1753!

    We only had 25.2 mm of rain in Staveley (between Sheffield and Chesterfield) for July, and just 239mm so far this year. Everywhere is bone dry and brown.

    It's been a fairly settled July here in Sunny Sheffield only 23.5 mm of rain the driest since 1995. Day time temps bang on average while cool nights dragged the overall average down to below average. June was below average as well.
    So far a dry but cool summer. Poor old trees are going yellow due to lack of water and the grass is dying off.
