Planning Outlook

Ground conditions remain very dry with wildfire risk; some areas in north Wales, the Peak District, and Cairngorms NP are currently inaccessible due to fire hazards. Weather remains settled late weekend into next week as high pressure persists west of Ireland. A northerly flow will cool temperatures slightly, dawn temperatures in the middle single digits in Scotland; staying warm in England and Wales but hill temperatures unlikely reaching the 20s. Cloud and drizzle starts to affect northwest Scotland more often, occasionally drifting further south, chance of an area of rain slipping south through the country Tuesday to Wednesday, though totals likely small. An unsettling trend is indicated for the following weekend, bringing wind, some rain, and cooler temperatures.
