Planning Outlook
Chilly through mid-week, particularly across the Scottish Highlands where morning freezing level sometimes below 800m; patchy frosts developing in the glens and corries, though always thawing soon after sunrise. Wednesday is likely the chilliest day. Mixed weather with showers drifting around the country, though total rainfall will be fairly small. Wind often light as well, though variable afternoon breezes will form, particularly around showers where gusts may be suddenly strong. Local low fog in the mornings, typically lifting towards high terrain, often above summits though regions for best breaks are uncertain; often cloud with just glimpses of sun for most. Next weekend sees more unsettled weather, a stronger easterly wind establishing over England and Wales with more frequent, heavy showers here.
