Fahrenheit measurements are highly intuitive for weather because they cover the vast bulk of experience in temperate climates. Here in Pennsylvania, we rarely get below zero (setting aside "wind chill") nor rarely above a hundred. Everyone immediately knows what the thirties or the eighties or the fifties feel like.
All of that experiential knowledge is lost when the range tops out at about 40, but veers into the negative in winter. Feh.
Heh, Louisianians consider the sixties to be cold. Upper seventies is juuuuust right.
