Planning Outlook
A core of high pressure lingers northeast of Scotland well into the week. The weather will be mostly sunny but also windy, particularly in Wales and the southern Pennines; challenging conditions are likely for several days on high Welsh mountains, powerful gusts over tops and downslope to the west requiring great effort to maintain stability. Despite Monday showers, dry ground conditions, warm temperatures, and wind bring a high risk of wildfire. More settled in Scotland, though breezy in the west, most hill cloud in the east. Detail becomes uncertain into next weekend, but a rising risk of showers and longer spells of rain as pressure begins to drop.
