2180 meters    -7, Winds were 50-75 KPH S      --Whistler Peak
1835 meters    -4, Winds were 20-35 KPH SSW --Roundhouse

  660 meters   +3, Valley Temp, Max Temp Yesterday was +9.7, 13.1 mm of precip recorded

    As of 07:00 Hrs we have overcast skies, variable visibility and very light snowfall.


A weak warm front in a Westerly flow aloft will bring light precipitation to the area for most of the day intensifying to moderate precip tonight as  a trailing cold front pushes through.  The freezing level will hover in the 1200-1400 meter range. Another warm front for Saturday in a Southerly flow aloft will bring light precipitation to the area with a cold front passing through in the evening. By Saturday night we should see moderate precip with the FL ranging from 1400-1600 meters, possibly higher. This front will continue into Sunday with light to moderate precip  and cooler temperatures by Sunday afternoon. The FL should get close to surface by Sunday evening. And so the pattern continues into Monday. Guesstimates: 15-20 cm by Saturday morning, 15-25 cm by Sunday morning, 15-20 cm by Monday morning.

      Low in the Gulf of Alaska will send a weak cold front into our zone today.

          Moderate Westerly flow aloft with the brunt of the precip occurring tonight.

      More of a Southerly flow Saturday.

      Low will continue to send weak frontal bands our way.

    Overcast Monday with light to moderate snowfall.

    Overcast Tuesday with light to moderate snowfall.


    Thursday morning 08:20 Hrs, no line up on opening day for Blackcomb. A dry day!!

    Considering that we received 60 mm of rain through that very warm front, we did well.
