Alpine Forecast
After a 3 days of arctic outflow, it looks like its going to break down and let in some snow. These events are always interesting as warm air rides up over top of cool air trapped in the valleys. Yesterday we saw an inversion up top begin to develop. Expect to see freezing rain in some areas more towards Squamish today and tonight. The alpine should see lots of snow this week as a series of systems are lining up in the pacific.
Heavy precipitation is expected to start on Friday afternoon. The freezing level is expected to remain at valley bottom in this region, although temperatures will climb to around -5C. Overnight, accumulations will be heavy and strong southwesterly winds will blow. Around 20-30 cm dense new snow is expected to be on the ground by Saturday morning. On Saturday, further heavy snowfall is anticipated, as unstable, convective air moves in behind the storm. Temperatures will cool slightly and strong SW winds will continue to blow. On Sunday, another punchy winter storm system will bring further heavy snowfall.
Keep in mind avalanche danger will rise rapidly today and through next week as a already weak snowpack gets loaded up. A significant avalanche cycle is expected......
