VANCOUVER (NEWS 1130) — People in parts of the Lower Mainland are waking up to snow Sunday morning. But how much will fall and how long will it last?
NEWS 1130 Meteorologist Michael Kuss predicts a mushy mix of snow and rain for most of the region, with heavier snow in higher elevations.
“From a meteorological point of view, what we’re looking at here is cold arctic continental air that is pushed out of the prairies all the way across B.C. and is in place now for the lower mainland,” he explains.
“That’s combining with a pretty run of the mill low-pressure system that’s tracking down the coast. It’s not that intense really, but because it’s cold we’ll get snow for a good chunk of the area if not all of it, as opposed to rain.”
By 4 AM Sunday Low will be west of Vancouver Island. If track is farther west it'll be cold and drier. If low farther east more precip but more rain than snow. Met advice: be ready for snow. @NEWS1130 pic.twitter.com/nlSDzbweaT

With higher temperatures, the region would be seeing a fairly unremarkable amount of rain, Kuss notes.
“If it was six or seven degrees across the area it would only be 10 maybe 20 millimetres of rain, but that’s 20 millimetres of water and if we translate that over to snow, the potential is there for 20 centimetres of snow. I don’t think we’re going to see those types of amounts, we’re looking at, I would say 10 centimetres of snow maximum because there is going to be rain mixed in there.”
And he says the cold weather is set to stick around.
“This is the first time we’ll see low temperatures for a stretch that’s longer than a day or two. It looks like at least a week to two weeks where we’ll have temperatures that are below average.”
