Planning Outlook

High pressure will bring many days of fine weather and frequently little wind next week. Beforehand there is one 'troublesome' front to contend with: On Friday and the weekend its zone of low cloud and patches of drizzly rain drifts into NW Scotland and then slowly southeastwards (but will stop and temporarily edge back again), before clearing to often clear skies and frosty nights (in valleys). Until it clears, even away from the front, fog will be extensive, albeit some mountains will protrude above the fog into daytime bright sunshine.
