A Yellow thunderstorm warning has been issued for all of Scotland’s mainland, with the disruptive weather set to hit early tomorrow morning.

On top of the Met Office alert issued earlier this week which covered central and southern Scotland, forecasters warn of extended thunderstorms most of the country.

Torrential downpours will bring the chance of ‘sudden flooding’ between 4am on Friday and to last until just before midnight on Saturday.

Met Office spokesman, Grahame Madge, said that although it is 'virtually impossible' to determine the area that will be most impacted, we can expect to see the bad weather cover all of Scotland.

He said: “We do have a very unsettled weekend in prospect, with a lot of it covered by a thunderstorm and rain warnings.

“We have got an area of low pressure which will be milling around over the UK bringing rain to quite large parts, so I think everywhere can expect to see quite heavy showers.”

 “We know the footprint of where we think the heaviest rainfall will be, but it’s like a boiling saucepan: you will get bubbles coming up, and trying to pinpoint where the next bubble will be is virtually impossible.”

To combat the high risk of the extreme weather Network Rail Scotland today announced that they are currently in the middle of an 'extreme weather teleconference', to figure out transport plans ahead of the weekend.

The Met Office warning reads: “There is a small chance that homes and businesses could be flooded quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds.

“Where flooding or lightning strikes occur there is a chance of delays, and some cancellations to train and bus services.”

 

Their forecast adds: "Heavy showers are expected to break out across much of the UK again on Saturday.

"The heaviest showers are expected within the warning area where some of the showers will be slow-moving and thundery.

"Not all locations will be affected by the heaviest showers, with some areas escaping much in the way of rainfall.

"However, where the showers do occur there is potential for a further 20-30 mm of rain in a relatively short time period and during the course of the day there is a chance that some places could see as much as 50-70 mm building up."
