Snow is falling in parts of Calgary and more is expected overnight.

CBC meteorologist Danielle Savoni says most will melt on contact with the ground. Temperatures are forecast to drop to freezing overnight.

It’s the first snowfall since May 5 when Calgary got just over 12 centimetres, says Savoni.

"While it may be cold and snowy right now, this will be short lived. By Thanksgiving weekend, we’ll be looking at mid-teens and sunshine — right where we should be," says Savoni.  

The temperature dropped 20 degrees in 24 hours. Yesterday at 6 p.m. MT it was 23 degrees, at the same time Tuesday, it was 3 degrees.

"It is cold, especially this time of year. It should be 15," says Savoni.

The meteorologist warns that the roads could still be slippery for the morning commute.

The City of Calgary’s Sean Somers says the city is prepared with sanding trucks and salt on standby.

"We're not anticipating it’s going to amount to much, but certainly we want to to be safer than sorry," he says.

"What we’re doing is loading a few trucks in each corners of the city, in the event that we do see any accumulations of snow that we do have the ability to get out there and get some salt down."
