If, for example, you're ten miles into the trip and start thinking, "Man, my hands are just too damned cold," you could see what temperature it is and plan to wear warmer gloves the next time you see that temp on the forecast.
That does make a degree of sense. But for medical/health reasons I wear gloves whenever I'm riding. And I do carry a windbreaker and lightweight rain jacket as well as my first aide kit and whatnot.
