Fri 22 Aug Highlands and Eilian Siar

High pressure is likely to be the dominant feature at first, initially centred near to Iceland, allowing a north to northeasterly airstream to affect much of the UK, leading to rather cool conditions. High pressure is likely to progress SE across the UK for a time, bringing widely fine and dry conditions and for some, an increase in temperatures, relative to the previous few days. Whilst this is happening a deep area of low pressure is likely to develop in the North Atlantic, linked to Tropical Storm Erin. The final week of August may see Atlantic weather systems progress over the UK, 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.
