    Man made snow was skiing well yesterday.

    Surface Hoar is getting larger by the day.

2240 meters      -7, Winds were 35-50 KPH from the S
2180 meters      -6, Winds were 40-50 KPH from the SSW
1860 meters      -6, Winds were 25-35 KPH from the E

1550 meters      -5, 2 cm of new new snow, Base 91 cm,  Relative Humidity 96%.
  660 meters      -3, Valley Temp, Max Temp Yest -0.9.

    As of 07:00 Hrs we have overcast skies, variable visibility and it is snowing lightly. 



For the forecast, a weak trough will bring light snow to the area until early this afternoon, in a Northerly flow aloft. A strong high pressure system will begin building on Sunday with unsettled conditions Sunday morning before modified Arctic Air moves into the area for Sunday night with cold clear conditions into Tuesday. Wednesday is also looking sunny but it appears the freezing level will be rising to 2300 meters by Wednesday evening with an inversion. Clear skies until Thursday, when a weak upper trough may enter the area Thursday evening into Friday with clouds and the possibility of some light snow.    Guesstimates 2-4 cm by this afternoon.


    Majority of the energy is heading South.


     Narrow band passing by today will bring some light snow.


   
    We could receive 2-4 cm by this afternoon.



   Looking dry by Sunday.

 Duffy Area Field Observations from Lee Lau;

Wango

Your Christmas Duffey report is that things are still pretty thin. Went for a walk in a zone East of Cayoosh Pass. 40cms (or less!!) at trailheads around Cayoosh Pass including Cerise. 

Temps -8. Winds light. Surface hoar growing like crazy - 2mm+ grains. 
Snow depth is paltry; 40 - 60cms at 1450m. 90 cms at 1600m with creeks barely covered and someone postholing out on the skintrack (injury) almost punching through to the creek multiple times. 100cms or so at 1750m and that's optimistic.  Better coverage up high of course but you got to get through the bush to get there

Good news is that what snow there is on N W and E aspects is so low density (ie good skiing) that there's imperceptible surface slab That may not be true on S aspects which we didn't check. Also windslab may form in the mild Arctic incoming the next few days.

Near ground basal faceting around treewells so watch for that. Totally different snowpack in this zone than the Whistler area - to state the obvious.




    Thin layer of Stratus cloud on Mount Currie. Thick layer in the valley.

    Front began to move in around noon Friday.

    Whistler Peak was shrouded in cloud for most of the day.

    The Alpine is in Awesome shape.

    Fissile Mountain.

    Snow making will make a huge difference on the lower mountain, good temperatures for maximum production.

    Great man made snow being produced Friday.
