Planning Outlook

A complex pattern into the start of August as weak low pressure is nearby to the west. Some showery bursts of rain, possibly thundery in places on some days, locally persistent rain possible, but some places may well escape drier. Cloud varying over the hills from day to day. Strong southwesterly winds later this week, then becoming more variable in speed and direction over the weekend into early next week, may strengthen again for periods. A generally showery westerly may then prevail during next week. Temperatures near average or on the cooler side for Scotland, warmer for Wales and Peak District. Beware ongoing fire management restrictions to access despite rain in the forecast.
