Scots could be treated to a bonus late summer heatwave after record breaking temperatures at the weekend, meteorologist Jo Farrow writes.

The definition of a heatwave in Scotland requires three consecutive days where temperatures are 25C or above.

On Sunday, Aberdeen recorded its warmest September day ever.

On Sunday, the city saw temperatures soar to 27C – beating the previous record of 25.9C by more than a degree.

With 27.1C at Fyvie Castle, it also beat its previous record of 26.9C.

It comes as Scotland is set to enjoy a very warm week with plenty sunny weather ahead.

Although it is unlikely the overall Scottish September record of 32.2C in 1906 will be broken – highs of 27C are possible.

Central Scotland or Glasgow might meet the heatwave criteria while France and other parts of the UK are expected to see temperatures surpass 30C.

Grampian should see 27C again on Monday with a southwesterly breeze resulting in the Foehn Effect to the lee of high ground where air dries and so warms as it is lifted over mountains.

By Tuesday, the flow will have changed to an easterly and so temperatures will be lower by midweek.

Haar and low cloud will appear for North Sea coasts.

Western Scotland will be warmer by day and night in the light easterly breeze.

The daily highest minimum, which happens when we have a very warm night, on record for September in Scotland is 18.7C.

We could come close to this on Tuesday night in western Scotland.

There is a weak weather front over Shetland to start the week with more cloud and patchy rain for the islands but the only other threat of rain is on Thursday.

There is a risk of a few sharp showers, even thundery ones pushing up from the south but there is uncertainty around this part of the forecast and little detail at this stage.
