A slab avalanche released into the snow making  reservoir on Blackcomb. Not sure when? Slippery bed surface!

At 2280 meters the temperature was -10, winds were 15-25KPH from the SSE. At 1650 meters there was 2 cm of new snow recorded, the temperature was -5.5. In the valley it was 0. Observations taken at 06:00 this morning.

For the forecast, it is a repeating pattern. A weak front will hit our area today. The moist northwest flow aloft will prevail into early next week. There is a chance that an upper level ridge may shift inland late next week. Flurries  today and into tomorrow, looks like it starts drying out by Tuesday. Guesstimates:  Today 3-5 cm, Tomorrow 3-5 cm.

It is a full moon tonight.

Long term forecast for the Peak to Valley race, Friday is certainly looking like the best day. The models are in conflict for Saturday. The ECMWF keeps the ridge here until Sunday, the GFS calls for a system to arrive on Saturday.  Hope the European model is correct.

Very interesting results

The unsettled weather yesterday threw a bit of everything at us. At times you could see some serious convective flurries happening in other parts of the valley. One side of the valley would be sunny, the other side snowing. In the valley it was raining then snowing within minutes.

Large conglomerate flakes were descending to the valley .

Not much going on when you look at this image of the 500 mb now time picture. 21:30 Jan 26
