We Will Rebuild the Snowpack

But first, a reprieve from precipitation for the interior ranges and the SW ranges. Clear skies and fog patches in the interior will give way to incoming cirrus ahead of the next system. Snow arrives overnight and continues into Saturday. There isn't too much moisture but given the cold temperatures, snow density will be lighter resulting in higher snowfall accumulation; watch for upslope snowfall near Waterton National Park.

As the low reform in Montana late Saturday and moves east, a ridge of high pressure takes its place in B.C. for a relatively calm day on Sunday. A strong low approaches the coast late Sunday packing more moisture. The system will bring snow to coastal ranges and southern interior ranges with the heaviest accumulation over Vancouver Island and SW ranges Sunday night and Monday. The South Columbia, K-B and Lizard Ranges will benefit the most from this system for snowpack building with lesser accumulations for the Purcells on Monday.

A ridge of high pressure builds behind the low Monday night with clear skies and valley overnight lows in the minus single digits in the southern interior.

A southwest flow on the 500 mb loop will feed moisture into southern B.C. today but a deepening low off in the Pacific will cut off the moisture from reaching B.C., keeping it from forming into another atmospheric river event. A ridge of high pressure builds over the eastern Pacific on Saturday for a brief reprieve.

A shortwave trough over the Gulf of Alaska at 4am Sunday morning will tap into a baroclinic zone and re-energises as it moves towards the B.C. coast. This pattern will bring heavy snow to the Vancouver Island and SW ranges and light to moderate snow to the southern interior ranges on Sunday and Monday.

Another ridge of high pressure moves into the province late Monday.
