Planning Outlook

Frontal rain into south Scotland and north England on Thursday, though details of how the front will move are currently uncertain. Starting on the milder side south of the front, fresher air arrives behind the rain Thursday into Friday, sun breaking out with a few showers - Scottish high summits drop back close to freezing with some snow falling on higher tops. Higher pressure builds on Friday, easing remaining showers with plenty of sun breaking out though a gusty northerly wind will persist for a time. A window of settled weather over the weekend and scope for local inversion conditions. Clear night skies allow for chilly mornings, ground frosts likely, and may remain breezy south Pennines and Wales. Pressure remains high into the next week though a few brief unsettled moments come and go.
