Grouse Mountain - The Peak of Vancouver (Base: 2,840', Top: 4,100')
6-day Forecast Discussion Updated for Saturday, November 21, 2009All of us at Snowforecast.com thank you for your support this season! We wouldn't have been able to do this without your viewership.

The following discussion applies to Southwestern British Columbia, including Whistler Blackcomb, Hemlock and Mt. Cain; along with the Cascades of Washington including Mt. Baker, Stevens Pass and Badger Mtn.
The active weather pattern looks to continue as the area will see a series of storms move through the area every 36 to 48 hours. The next system arrives on Saturday with snow developing during the day on Saturday. All mountain areas will see snow as snow/freezing levels will be below 2000 feet. As the area of low pressure moves ashore Saturday afternoon, look for the winds to increase slightly during the afternoon and evening. The highest accumulations look to be in the central Cascades, including Mt. Baker with amounts during the day between 6 and 10 inches. Lesser amounts around 4 inches are possible to the north near Whistler Blackcomb and to the south near Crystal Mountain, WA.
Saturday night the snow will continue and pick up in intensity with a 8-12 more inches possible in the central Cascades and another 4 to 6 inches north and south. This area of low pressure will quickly exit the area on Sunday morning, leaving in its wake a few flurries. Temperatures over the weekend will be in the 20's with highs near closer to 30 degrees for valley locations near 2000 feet.
As we head into the week, warmer temperatures will be with us as the freezing level rises to near 5000 feet by mid week. The next system will move in Monday into Tuesday, with another system moving in from the Gulf of Alaska by midweek. Both of these systems will have moderate rain and snow with them; but as the freezing level rises, look for more a mix of rain and snow than what we have seen the past week. Highs will climb into the mid 30's and closer to 40 by Tuesday and Wednesday.

Long range forecast / discussion...November 27 to 30
After we see a warm up and rising freezing levels during the midweek, an area of low pressure and associated front look to move back into the area bringing with it a rain/snow mix that will change to all snow by Friday the 27th. Snow levels look to fall back to 2000 feet by the end of the week with a few flurries possible early next weekend. Beyond that it looks active and cold enough for all snow for the first week of December.BT
