Planning Outlook

A fine week of summer weather - warm and dry with pleasantly warm temperatures and often plenty of sunshine. High pressure 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 for 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. A cooling trend toward the weekend as north-northeasterly winds develop, a few showers possible, but a dry theme likely into early next week.
