Planning Outlook
A fine week of summer weather - warm and dry with pleasantly warm temperatures and often plenty of sunshine. High pressure north of the country keeps the skies mostly clear, some low-level cloud rolling inland from the North Sea at times. A prevailing easterly flow, pushing the warmest temperatures to western hill groups, valley temperatures often 25C, or warmer for Wales and Peak District, at times 30C. A fairly sustained breeze most of the week in England and Wales, at times stronger and quite gusty. Notably dry ground conditions, beware very high fire risk. Later in the week, an increasing risk of thundery showers forming, with a cooling trend into the weekend 18-19th.
