Glasgow's Old Firm derby could be hit with lightning strikes as Met Office forecasters expect thunderstorms to roll in.
The game kicks off at Parkhead at 12.30pm on Saturday. A yellow weather warning is in place from Friday south of Glasgow, in areas such as Dumfries and Galloway, the Ayrshire coast and parts of Argyll.
But Glasgow will not escape treacherous conditions as forecasters expect thunder and lightning to hit the city in time for kick off at Celtic Park. Stormy weather hits Northern Ireland first before crossing over to Scotland.
