Planning Outlook
Chilly most or all week, particularly across the Scottish Highlands where fresh snow in some areas and morning freezing level sometimes below 700m; 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 is indicated to be wet in Wales and England; detail remains uncertain in Scotland.
