A YELLOW thunderstorm warning has been expanded to include northeastern parts of Scotland.
The Met Office said that the warning is valid until midnight on Sunday.
The warning was announced on Saturday for a majority of the central belt and has now been extended to parts of Aberdeenshire.
The warning also covers Northern Ireland and northern parts of England and Wales.
The Met Office advises the weather may bring disruption from 2pm to 11.59pm on Sunday, September 10.
An additional warning has come into place until 6.00am Monday for the central belt.
As a cold front gradually moves south through the weekend, the change will bring the risk of thundery downpours in some areas on Sunday.

The public have been warned that flooding of homes and businesses could happen quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds.
The Met Office is also warning power cuts might occur and other services to some homes and businesses could be lost.
It comes after Scotland experienced a week of high temperatures, some areas reaching to 29 degrees.
Met Office chief meteorologist Paul Gundersen said: “Although much of the UK will see high temperatures and sunny skies continue on Saturday, in what has a possibility of being the hottest day of the year so far, there’s also the potential for some thunderstorms, which has resulted in a yellow warning being issued for much of central England and parts of east Wales.
“Temperatures will begin to trend downwards from Saturday in the far northwest of Scotland, with a cold front gradually moving south through the weekend, bringing with it the risk of some heavy and thundery downpours on Sunday as well.
"However, the southeast will hold on to the high temperatures the longest and could still reach 32 degrees on Sunday.”
Looking ahead, by the early part of next week there will be a return to a westerly weather regime, with a mix of sunshine, showers and some windy conditions most likely, with temperatures returning towards average for the time of year.
