Weather: BBC forecast map shows fatally low -88C in Norwich BBC Breakfast weather map shows temperatures fluctuating by 177C Map behind presenter Carol Kirkwood showed 88C highs and -88C lows Extreme temperatures in isolated areas - rest of UK appeared normal A severe weather warning has been issued across Britain tomorrow, as temperatures are set to plummet to -88C tomorrow - followed by a leap of 177C to 88C later in the day. Or at least that's the forecast according this morning's BBC Breakfast - which flashed up the somewhat extreme conditions on a satellite map during this morning's show. Weather presenter Carol Kirkwood stood in front of the screen as it showed how freezing temperatures - only ever found at the Antarctic in the depths of winter - descended upon Norwich, Glasgow and the Shetland Islands for tomorrow morning at 5am. Cold front: BBC Breakfast's Carol Kirkwood confidently predicted a rainy spell for northern parts of the UK... but the map behind her warned of more extreme conditions The next screen then showed a sizzling 88C for Stornoway, Aberdeen, the Channel Islands and the Shetland Islands for later in the day at 4pm. The rest of Scotland is under the influence of a weather front... Ms Kirkwood began - as the technical blunder was noticed. A temperature of 88C has only been recorded once - in the Nevada Desert in America. The freak conditions would be fairly isolated, the map suggested, as the rest of the country was forecast to enjoy normal to pleasantly warm temperatures for the time of year, ranging from 11C in the morning to 20C later in the day. Hotting up: Carol Kirkwood turns to show viewers how the temperature is likely to rise a few degrees as the morning progresses Ms Kirkwood's colleagues were quick to point out the technical blunder. Presenter Bill Turnbull said: '88C is well above average, I don't know what clothes to wear now.' Co-presenter Susanna Reid joked: 'When you said changeable, I didn't know quite what you meant.' Ms Kirkwood tried to explain the slip-up, saying: 'The new data must be coming into the system.' Oops: The moment Ms Kirkwood recognised that she had been upstaged by the satellite screen all along
