Planning Outlook
Largely dry weather prevails as high pressure remains nearby to the west. A northwesterly flow keeps 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 affects northwest Scotland more often, occasionally drifting further south. Despite this, ground remains very dry with high fire risk, with ongoing wildfire management limiting access in places. A more unsettled trend develops during next weekend, bringing wind, rain and showers first to Scotland and increasingly widely. England and Wales remain quite warm.
