On Tuesday, rain will move southward, enabling air from the Arctic to develop into a northerly flow.
Strong winds are expected to affect northeastern Scotland until 6 p.m., according to a yellow weather warning issued by the Met Office. This means that there may be some minor traffic disruptions in certain areas.
The midweek temperatures are expected to be much below average, with daytime highs of 10 to 15 degrees Celsius (50 to 59 degrees Fahrenheit) and considerably lower feeling due to the strong wind.
Temperatures at night will likely be in the low single digits, with a patchy frost on the grass.
On Wednesday and Thursday, the cold airmass will bring showers, some of which will be heavy and thunderous. A little snow is also expected on the peaks of the Scottish mountains, which is not out of the ordinary for September.
As wind and rain blow in from the Atlantic on Friday, it appears that the northerly flow will be broken, allowing temperatures to rebound to about average for the weekend.
