Another frontal wave has brought strong winds and light snow fall into the area overnight and into this morning in a Westerly Flow Aloft. The FL is a bit of a concern but looks to stay below the 1000 meter mark (800m likely).  Frontal band will ease off by this afternoon with light snow flurries and unsettled conditions into Wednesday. Another vigorous front will arrive Wednesday evening with moderate to heavy snowfall into Thursday morning. A weak ride will build for Friday strengthening for the Christmas weekend. As of now Christmas day is looking sunny. Yes, the perfect scenario for an awesome X-Mas Day. It will be cold!! Guesstimates: 8-12 cm by Wednesday morning, 8-12 cm by Thursday morning, 20-25 cm by Friday morning, as always subject to change!! Epic conditions so far this winter!!!

    Most of the precipitation went South.

    Unsettled after the cold front pushes through this am.

    Unsettled Wednesday morning/afternoon.

   Another front arrives Wednesday night.

I'd just like to report that the metallicus and vitreous layers are sliding badly on all aspects this afternoon in Vancouver. It appears that there is an aqueous layer lubricating the slides, which can be triggered by the thump of a shovel.

    Even with cold temps, some sun---right aspect and angle !!

    Some very dry powder!!

    Nice light Monday morning.
