Prévisions météo en montagne

This is turning out to be a February to remember! Snow, all the way down to sea level, seems to be a recurring theme! With the quasi-stationary ridge set up over the Pacific Ocean, this is allowing for cold air to continue to persist over BC. Every so often a trough of low pressure will slide down the BC coastline and hit regions with snowfall accumulation.

Talking about troughs of low pressure, another one will slide down the coast today maintaining unsettled conditions with possible bursts of flurry activity over the south coast and southern interior due to the convective nature of the atmosphere. The 12Z HRDPS is forecasting 10 to 20 mm of precipitation for the South Coast ranges today with a freezing level near valley bottom. A ridge of high pressure will bring sunny conditions to the northern and central interior.

A surface low will be southwest of Vancouver Island on Sunday morning and it will dissipate during the day. Some scattered showers or flurries will remain Sunday morning, but a drying pattern will quickly set up on Sunday afternoon.
