Meteorologically, as Summer is from 1 June to 31 August, this is our last week of summer.
There’s no heat wave in sight, if there is you’ll be the first to know. It’s felt autumnal this week with many people packing away their summer clothes and even switching on the heating. Laura has more in her blog...
Wednesday night was one of the coldest we’ve seen all summer and for some one of the coldest August night for years. The temperature fell to 2.1C in Upper Lambourn (W Berks) the coldest night for England this summer and their coldest August since recordss tarting in 1997. Hurn fell to 2.7C, the lowest August temperature since 1993. Larkhill dipped to 3.5C, the lowest since 1970. Boscombe Down dropped to 4.2C the lowest since 1979, and with 6C, Plymouth Mountbatten had their lowest August temperature since 1982.
Some of us have a bank holiday and in true bank holiday tradition it’s looking wet. However the rest of the weekend won’t be a wash out, we’ll all see some sunshine with Sunday the best day for many.
Friday, a chilly start in the north and sunny spells for many. The wind will feed scattered showers into Northern Scotland, eastern England and east Wales with a small risk of a light shower elsewhere.
Saturday another chilly start. Again a day of sunshine and showers, mostly across Scotland and England (away from the south and south west). Heavy showers with hail and thunder will develop in eastern England from Lancashire to East Anglia including the Home Counties. Much of Northern Ireland, Wales and south west England will have a fine and dry day thanks to a weak ridge of high pressure building in from the west.
Sunday will be one of the coldest mornings ofthe summer with many local records broken away from the west. It’ll be dry and sunny for all at first and will stay that way for central and eastern areas. However a weather front in the Atlantic will bring cloud in the far west by lunch time, with rain affecting Northern Ireland, Wales and the south west by the evening.
Through Monday, cloud and rain accompanied by a strengthening wind will move across much of the UK, shattered showers with some bright spells will follow in the west as the rain clears. Although a milder westerly wind will have developed it’ll still feel cool in the rain but milder in any sunshine.
Last weekend earthquakes began in central Iceland, underneath Europe’s largest ice cap. There are now concerns that Bardabunga volcano may erupt. Seismologists think that the activity means that molten rock, or magma, is moving around underground. Since then thousands of tremors have been recorded, this is known as a quake swarm and indicates that an eruption could be close. On Monday the Icelandic Met Office raised their warning level to orange, one down from the highest, they don’t believe an eruption is imminent but there is heightened unrest and the potential of eruption. The last time Bardabunga erupted was in 1910. Quakes may continue for days, weeks, months or simply fade. If an eruption occurs it may not breakthrough the huge ice cap. There is lots of uncertainty, you can find out more from the Icelandic Met Office.
The weather remains unsettled; flip flopping between showers, sunshine and rain. Rain will be heavy at times, especially in the northwest with the risk of gales. The driest and brightest weather is most likely to be in the southeast later in the week. This weather actually ties inwith long-term weather stats. Some meteorologists believe the weather ‘has a memory’ as certain times of the year a certain type of weather often happens. These seasonal tendencies are called singularities a word coined by the German climatologist, A. Schmauss, in 1938. If this theory is to be believed then from 20 August to 30 August (peaking on 28) we have ‘late August winds” this happens 76% of the time. However there could be good news as warming often follows this. 82% of the time from 1 September to 17 September, (peaking on 10th) we have ‘early September warmth’. Fingers crossed!
