    Snowing lightly in the morning.

    Pretty much the picture for the whole day.

    The occasional break in an overcast sky.

Winds will pick up this afternoon with 60-70 KPH possible in the alpine as a trailing cold front pushes through.  Friday is looking overcast with some light/moderate snow and the FL hovering in the 1000 meter range. Unsettled Saturday with high pressure building  Sunday into Monday. No decisive information from the models for next week. Standby! High may possibly stick around for the week with warmer temperatures!!
Guesstimates: 15-25 cm by Friday morning, 15-30 cm by Saturday morning, 1-2 cm by Sunday morning.

    GOES IR image for today. Still a chance most of the moisture could go South!!!

    Low will send more snow our way than forecasted yesterday.

    High is still hanging in the Pacific.

    Thursday, Low and Arctic Airmass are pushing each other around.

    Friday the front will slide South.


    Surface was nice in places.

    Snow conditions are pretty good.

    More ice forming.

    Plate stellars accumulating in the valley.

    Creeks are still open, even in the alpine.

    Sticking to the trees.

    Light dry snow.
