A plume of hot air will see western parts of the country including Ayrshire, Argyll and the west Highlands experiencing high temperatures and warm sunshine, with the east coast set to be slightly cooler with “haar at times”.
STV weather presenter Sean Batty told the STV news website that from midweek some parts of the country could see the mercury rise to heights of 26C in some areas - which could see some Scots enjoying the warmest day of the year so far - with the sunshine set to last through the weekend.
He said: “Temperatures will reach the low to mid 20s in the west and could possibly exceed the highest temperature recorded so far this year of 25C at Floors Castle in the Borders.
“The good weather looks set to last through the holiday weekend, with some of the highest temperatures of the week expected to occur then.
“While the west of the country will enjoy the highest temperatures and long spells of sunshine, unfortunately due to a slight easterly air flow, there will be haar on the east coast at times which will make it much cooler.
“Some coastal areas may struggle to reach the mid teens on some days.”
