Family Day is looking to be quite the wintry one for many across British Columbia as a series of Pacific low pressure systems move onshore. 

The first wave will spread light snow across southern B.C. overnight before changing to rain through Monday. 

"Light snow will begin overnight Sunday across the South Coast," says Gina Ressler, a meteorologist at The Weather Network. As temperatures warm above freezing through the morning, snow will change to rain (around 10-15 mm) across the South Coast."

Environment Canada has yet to issue any warnings, but say the biggest concern with this system is the threat of freezing rain over parts of Metro Vancouver and the Fraser Valley Monday morning. 

"Local effects and small changes in elevation will play a role in how quickly the snow changes to rain or freezing rain," adds Ressler. 

This first wave of moisture is set to bring 2-5 cm of snowfall to Vancouver, while higher elevations such as West Vancouver, North Vancouver and Coquitlam can see 10-15 cm.

Snowfall warnings are in effect for high elevations mountain passes and inland areas of the North and Central Coasts can see 15-30 cm by Monday evening.

Meanwhile, all eyes are on Tuesday's forecast as a moisture-packed system pushes into the province.

"The second wave will arrive late Tuesday bringing a heavier round of rain to the south coast, with heavy snow at high elevations," says Ressler. "The second wave will tap into some sub-tropical moisture, a set-up that is often referred to as a “Pineapple Express”. 

"While it is a bit early to pin down exact precipitation totals, current model guidance suggests that around 40-60 mm is possible across Vancouver and the Lower Fraser Valley. Another 15-30 cm of snow is possible in parts of the interior and in high elevation mountain passes."
