Planning Outlook

Friday starts fresh with local valley frosts, freezing level onto the highest Munros. Bright for many, though showers affect west areas, particularly Scotland, and spread more widely afternoon. A window of settled weather follows over the weekend as a core of high pressure builds over Scotland. Clear night skies allow for chilly mornings with ground frosts and some valley mist. Sun breaking out, though some cloud will linger on upper slopes, only limited scope for local inversion conditions. An easterly breeze will keep the skies a touch cloudier in England and Wales, chance a little light rain for England on Sunday. Pressure remains high into next week though some areas of low pressure will try to break through. Forecast confidence reduces from mid-week with a risk of unsettled conditions returning.
