This indicates high probability for the weather over much of north and west Europe to be warmer and drier than normal. Crucially, just as in 1976, the normal high pressure belts extending out of the Azores which traditionally gives the UK its fine weather will be strikingly absent but replaced with high pressure close to or just east of the UK drawing up southerly winds. This is a very durable and repetitive weather pattern which can become difficult t o dislodge, often reinforced by attempts for low pressure to approach from the west but stalling and fizzling out as high pressure reasserts from the east.
The main feature of this summer’s weather is likely to be the sustained warmth with long runs of hot days, high humidity making it feel sticky and lack of appreciable rainfall. What rainfall there is will be showery in nature which will do nothing to alleviate pressure on water resources as showers are hit and miss and not everyone is guaranteed to catch them and during hot weather what rainfall there is tends to be evaporated away quickly.
Within the summer, we expect the core of the hot and settled weather to occur during June and July, particularly June which we think will be very pleasant with high pressure in charge across much of western Europe and the UK.
During July, the centre of the high pressure delivering settled weather is likely to shift more towards Scandinavia allowing pressure to fall over southern Europe and thunderstorms to develop on the continent, possibly affecting the south of the UK later on. Temperatures are however likely to be well above average and rainfall well below average.
Into August and the weather patterns tied into a weakening La Nina hint at the high pressure retreating further west into the Atlantic allowing more in the way of showers to develop. Temperatures may fall back a touch closer to average or just above and finally we may see some alleviation for parched soils in the way of average rainfall for the month although this is the most uncertain aspect of the forecast.
