Planning Outlook
Weather remains settled through next week as high pressure persists west of Ireland. Northwesterly flow keep temperatures nearer to average for the time of year, dawn temperatures in the middle single digits in Scotland; staying warm in England and Wales but maximum summit temperatures only to the high teens. Cloud and drizzle starts to affect northwest Scotland more often, occasionally drifting further south, chance of an area of patchy rain slipping south through the country on Wednesday, though totals likely small. Despite this, ground remains very dry with high fire risk, with active wildfires limiting access in places. An unsettling trend is indicated next following weekend, bringing wind and rain first to Scotland and increasingly widely. England and Wales may remain quite warm.
