Potential for heat in the south and east

Week 2: 02/08 to 08/08

Dry periods are forecast to be the most frequent in southern and eastern areas. In the west there is an ongoing risk of showers or longer outbreaks of rain. Thundery spells are possible too, particularly in the south and east of England. Temperatures on the whole are forecast to be above the average, and in the south and east it may be very warm or hot at times.

Note: A range of outcomes is possible and even southern and eastern regions could see some rain.

Forecast confidence is low.

Expected developments

Week 1

An Atlantic flow covers the UK for the first couple of days. High pressure then begins to build northwards bringing more settled conditions, especially to the south. However, later on there are indications of low pressure pushing up from the south.

The chart below is from the UK Met Global model. It shows pressure and precipitation at 00:00, Tuesday 30th July.

Week 2

High pressure areas centred to the south have some influence on the weather. However, there are indications of low pressure systems becoming slow moving as they approach the UK. They lead to the potential for unstable weather with hot and thundery spells, mostly in the south and east. 

The chart below shows the GEFS forecast mean surface level pressure on Sunday 4th August.
