UK weather

Headline:

Hot in the south, fresher in the north on Sunday.

This Evening and Tonight:

Rain across Scotland and Northern Ireland will spread slowly south, perhaps reaching northern England later. Elsewhere, mostly dry with variable cloud and isolated southwest showers. A warm night for many.

Sunday:

Rain in the north will drift southeastwards with some heavy spells. Elsewhere, sunny or clear spells and mostly dry, though isolated showers possible in the southeast. Feeling hot once again.

Outlook for Monday to Wednesday:

The next few days see high pressure in charge across all areas. Sunny spells for all with temperatures climbing day on day. Peaking on Wednesday into the mid 30s.

Something of a north to south split to start the period. Some rain or showers are likely in the north whilst it will be predominantly dry, sunny and hot in the south. The heat in the south will likely ease into next weekend but probably remain a little above average. Further into August high pressure will likely become more widely dominant leading to settled conditions for most. There are signs that low pressure systems or thundery interludes will interrupt this at times, but rainfall amounts will probably be variable, with some areas continuing to see relatively little. Temperatures are likely to remain above average, with a chance of a return of the hot conditions seen earlier in the period.

The broad theme of high pressure remaining in place at least close to the UK seems most probable, but with occasional more unsettled or changeable interludes. These interludes will either be the result of Atlantic frontal systems moving east or thundery plumes possibly drifting north from the continent. The broadly settled conditions mean that rainfall amounts overall are more likely to be below normal than above. Temperatures will probably be above average and some spells of hot weather and heatwaves are possible, especially in the south.
