UK Outlook for Wednesday 24 Jul 2019 to Friday 2 Aug 2019:

This period will tend to see a northwest to southeast split in the weather across the UK, with northwestern parts experiencing spells of rain, which could be heavy at times, as well as some periods of strong wind bringing a risk of coastal gales. By contrast, southern and southeastern parts of the UK should see much drier and warmer weather, which could be hot and rather humid at times, especially in the first half of the next week. Thunderstorms could develop as any hot, settled weather breaks down from the west. Beyond that, the forecast is more uncertain, but overall the northwest to southeast split will most probably continue. The south and southeast are likely to see some rain but it will be less frequent than in the northwest.

UK Outlook for Saturday 3 Aug 2019 to Saturday 17 Aug 2019:

As we move into early August, the final month of the meteorological summer, confidence is low in the forecast with no one single weather pattern looking to dominate. As is often the case in summer, this could well mean plenty of fine, dry weather, interspersed with occasional rain or thundery outbreaks, leading to marked local variations in rainfall. Temperatures are likely to be above average, perhaps more especially in the south and west.
