Planning Outlook
High pressure dominates most or all next week, becoming centred toward the north. Easterly breezes prevailing over England, Wales and southern Scotland, gusty for periods. Extensively dry, warm and sunny, although sometimes low cloud will affect more eastern mountains. Some early morning fog, hills warmer than most valleys at dawn. In southwest Wales, small chance of a local showery burst of rain early in the new week. The final week of August suggests some breakdown to the settled weather, but timing of any change is very uncertain. Very dry again underfoot with significant fire risk.
