Mostly cloudy for today with the chance of some isolated snow flurries in a Northwesterly flow aloft, with a cooler unstable air mass. Clouds will likely dissipate later this morning with some breaks. Unsettled but drier on Sunday as an upper ridge builds along the coast. The ridge will strengthen for Monday with elevated freezing levels (2500m). Tuesday is looking overcast with a slowly rising FL before a wet warm windy Pacific front arrives for Tuesday night into Wednesday. The FL could go higher than the peak on Blackcomb. Some inconsistencies in the models next week so will stop here for now. Guesstimates trace-2 cm by Sunday morning.

    Drying trend for today.

    High pressure will begin to build.

   Unsettled for today with more cloud in the morning. Chance of some isolated flurries.

   High builds on Sunday.

   A very wet warm front moves into the area Tuesday night.
