Fri 22 Aug Wales

High pressure is likely to be the dominant feature at first bringing widely fine and dry weather whilst a generally northerly flow leads to rather cool conditions. This will be increasingly eroded from the west as frontal systems start to move in from the Atlantic through the weekend, leading to more changeable conditions. Whilst this is happening a deep area of low pressure is likely to develop in the North Atlantic, linked to Hurricane Erin. This likely progresses towards the UK through the early part of the week. The changeable period will likely continue through the last week of August, especially in the north and west, with a small chance of widely wetter and windier weather developing. The evolution of this is highly uncertain though.
