At first glance, I thought you were referring to body temperature, to which I would answer that it's perfectly normal . . . if you are dead.
You must, however, be referring to the street temperature - and such changes are, although not common, not rare, either. Actually, today, the AM temperature when I left for work (in the dark) was about 30F (-1 C). It is expected to be about 50F (10 C) by mid afternoon. Roughly the same yesterday.
When I used to commute to work on a railroad, it was always very near dawn. Just a bit before sunrise there's usually a small increase in the wind and a rapid change in temperature. Probably a thermal wave produced by the oncoming warm air. Except, in the winter, it was unpleasantly cooler, and of course, with the breeze, that much more penetrating.
OK - suppose you don't go outdoors anymore. Will that help?
