Thunderstorms are set to batter the east coast on Wednesday evening, with a yellow weather warning in place for many areas.
The Met Office has put an alert in place for Dundee, Edinburgh and many other areas between 1pm and 8pm.
Driving conditions are likely to be affected, trains may be delayed and it's likely there will be some damage to buildings and structures.
The warning applies to Angus, Clackmannanshire, Dundee, Falkirk, Fife, Perth and Kinross, Stirling, Aberdeenshire, Moray, Highland, Dumfries and Galloway, East Lothian, Edinburgh, Midlothian Council, Scottish Borders, West Lothian, North Lanarkshire and South Lanarkshire.
The Met Office said: "Scattered heavy showers and thunderstorms will develop through this afternoon across much of central and eastern areas of Scotland, parts of central, eastern and southeastern England and southern areas of Northern Ireland, before easing during the evening.
"Where heavy showers develop, 15 mm of rain could fall within an hour and possibly 25-30 mm in 2-3 hours where showers become slow moving, along with lightning and hail."
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
