AC Milan's hopes of clawing some ground back on Serie A leaders Inter before the end of the year were hit by the postponement of their match at Fiorentina.
Milan are five points behind their city rivals following a run of four wins in five matches, with this weekend's programme the final round of fixtures before the league breaks up for Christmas.
Leonardo's men had been hoping to further close that gap and also ensure they would head into the winter break in second place, but heavy snow at the Stadio Artemio Franchi saw the fixture in Florence called off this evening.
Juventus will have the chance to climb above Milan when they play host to Catania on Sunday.
The day's other scheduled match between Bologna and Atalanta was also called off because of the snow and freezing temperatures which have swept across Europe.
That clash at the Stadio Renato Dall'Ara has now been rearranged for Sunday with kick-off at 1300 local time.
