I'm curious, do the most modern jets issue eye-catching alerts to the crew when the temperature changes significantly?

Thanks for the information. So you don't think I haven't flown much around the world, I can state I have flown across every line of longitude, as far north as Fairbanks and as far south as Perth. I just have never met the conditions you described after over 30 years of flying (US Navy, TWA, ATA, etc). I will say I have never operated in the South Atlantic area.
In all those years, did you typically operate at upper-altitude limits for weight and available power where this kind of thing would have automatically been a problem? If the oat did make a jump, would've you necessarily noticed?
