A weak upper level trough will bring unsettled weather for today in a Northwesterly flow aloft. A chance of some isolated flurries today with a mix of sun and cloud, the freezing level will hover just above the surface. Clouds will slowly exit the area sometime  Tuesday and the flow will become more Northeasterly as a cold high builds in our zone into the weekend. There is a chance some cloud could linger into Wednesday. We can expect cold temperatures and outflow winds in the valley during this period. As of now it warms up slightly by the weekend. Great weather for making snow, looking into the long range not much happening until hopefully December 3rd. Time will tell. Will start posting daily once Whistler opens. Guesstimates: Trace-2 cm by Tuesday morning, Trace-1 cm by Wednesday morning.
