But the freezing flakes weren't down to a surprise cold snap, they were a prize the three-year-old had won in a competition.
His thrilled mum, Suzanne, said family and neighbours were stunned when the tipper truck turned up at their home, in Possilpark, on Monday afternoon.
The 34-year-old, said: "We are all so shocked and delighted. I can't believe we have been so lucky to win.
"Kelvin was all ready with his coal and carrots to make a snowman, and all the kids in the street were invited to come along and play.
"It's great knowing we are guaranteed a White Christmas –what a great surprise."
Suzanne was among hundreds of people who entered the competition, run by Xscape Braehead and Snow Factor.
She nominated little Kelvin because of his "caring and loving nature".
Snow Factor is Scotland's only indoor, real-snow sports facility.
Located beside Braehead Shopping Centre, and within XScape, the £32 million facility, the biggest of its kind in the UK, features a 200m main slope.
Jamie Smith, owner of Snow Factor, said: "It seems Scotland will be seeing more rain than snow this Christmas, so we are delighted to be able to make the Kirkwood's family Christmas wish come true.
"There's nothing quite like waking up to snow on Christmas morning, and a garden full of it will certainly add to their Christmas experience.
"With guaranteed fresh snow conditions, Snow Factor, Scotland's newest snow sports destination is the ideal location for skiers and snowboarders of all ages to learn and hone their technique – whatever the weather."
