Right now i'm in Cortina, in the Italians Alps, with a sunny day but with a temperature now of -12°C while during the night we arrive at -25°C, but my city is Venice, and right now in Venice it's partially cloudy with a temperature of -2°C. In the other nothern Italian airports, the Christmas days is generally with nice weather but with cold temperatures: MilanMXP -4°C, MilanLIN -2°C, Turin -4°C, while in the center south it's partially sunny with snow in the center.
I remember two years ago that i spent my Christmas day at Milan MXP
waiting the end of a strong snowstorm to leave for my US holidays.
What's the weather in Yr airport?
Merry Christmas! Buon Natale!
