Wed 20 Aug South West Scotland and Lothian Borders

The details during this period carry low confidence. High pressure will probably be increasingly displaced to the north through the first part of this period, allowing areas of low pressure to potentially make inroads from the Atlantic. This brings an increasing possibility of stronger winds and rain, some of which could be heavy and thundery, especially for southern and western areas, but this perhaps becoming more widespread with time. Overall, temperatures look to remain above average, with the potential for some further hot spells, especially in the south. One of the determining factors of the forecast through this period will be the behaviour of what is currently Tropical Storm Erin as it progresses into the North Atlantic; this being a quite typical source of uncertainty in late summer.
