Presenter Kawser Quamer left viewers stunned when she fled the screen barely seconds into an apparently live segment on the day's weather.
Having just described incoming foggy conditions, Ms Quamer saw a red mist of her own when she stuttered on the next word, and walked off while pulling out her earpiece.
Once offscreen, she was heard saying to a member of the production crew "I can't speak this morning. It's not good, is it?"
The cameras then cut back to presenter Sally McNair, who had introduced the segment, sitting open-mouthed in the Glasgow news studio. She quickly regained her composure to explain there had been "technical problems, obviously".
A red-faced Ms Quamer later took to social media to explain that yesterday's incident was not down to losing her cool - rather, the wrong pre-recorded clip had been broadcast.
She tweeted: "Oh God! Wrong bit clipped for the weather at 7.30! Wasn't really throwing a hissy fit - honest! Am LIVE in few mins - promise to be there!!! LOL!! [laugh out loud] So sorry for the mix up!"
The presenter, whose profile describes her as a "rock chick and adrenaline junkie", later said she could see the funny side of her slip-up and was glad she had not been caught on camera saying something rude.
She tweeted: "Mortifying - but very funny now I've recovered from embarrassment! Thank God I didn't swear!"
Ms Quamer has presented the weather for a number of regional BBC outposts during the last few years, and is currently seconded to BBC Scotland.
She later revealed the mix-up happened on her last day at the station, saying: "Apologies for the mix-up at 7.30am - my last breakfast shift today and I fear that's now my lasting legacy!! C'est la vie."
Her fellow weather presenter Kate Kinsella was quick to pass on her condolences over the on-air blunder, and sent a message to Ms Kwamer saying: "oh lovely, (I had to watch sorry!) At least you didn't say anything you shouldn't ... and to be fair not your fault!"
Viewers also saw the funny side of the incident, while Sally McNair's shock at the debacle was also raised online. One Twitter user said: "Sally's not looked that dazed since she sat opposite Arthur Montford's jaiket."
The broadcasting blunder is the latest to hit BBC Scotland, which has been the source of several live on-air gaffes in recent years.
Last year presenter Sally Magnusson had a meltdown during the lunchtime news bulletin when a series of errors caused the show to descended into chaos.
First a live interview with sport presenter Phil Goodlad was cut off, and then a pre-recorded report about an exhibition by artist Ken Currie failed to start, although pictures were flashed on the screen. Magnusson ended the programme with a shriek of frustration after telling viewers an argument had broken out among production staff.
In 2011, presenter Catriona Shearer introduced the weather report only for footage of Adolf Hitler's deputy Rudolf Hess ranting at a Nazi rally to pop up instead.
That fiasco followed a piece about the 70th anniversary of Hess's landing in Scotland, which showed a picture of the Scots Christian missionary Mary Gardner, killed in a Jerusalem bomb blast in March.
A BBC Scotland spokesman said: "Despite how it looked, Kawser did not breeze out of the studio. A pre-recorded bulletin should have played out at that time, but unfortunately the wrong clip ran by mistake."
