FWIW, The Weather Channel says 28ºF for the low that night (though undoubtedly that will be after midnight), and Weather Underground says it will be 30ºF at midnight.
The predicted high for Sunday is -20 C (= -4F) and the overnight low is -26C (about -14F), so at midnight it should be somewhere around -10F. I was invited to a party, but we will stay home and drink eggnog, watch the ball drop on TV and go to bed.
