For the forecast, a weak frontal system has slid into our zone with cloudy skies and the possibility of flurries for this morning and early afternoon. There is a good chance of unsettled weather by the end of the day, as short lived upper ridge pushes in for Sunday. The ridge will degrade by Sunday night, unsettled weather with mostly cloudy skies can be expected as the first frontal wave influences the weather for Monday,  a cold front for Tuesday with a moist flow into Wednesday. Models are in disagreement as to what will happen later in the week but there is a chance of significant moisture from a Southerly flow during this time period.  Guesstimates trace to 2 Saturday, 4-6 cm by Tuesday morning, 18-24 cm by Wednesday morning, 10-15 cm by Thursday morning.

Presently in the Alpine there is overcast skies variable visibility and it is snowing lightly.

Some size 1 avalanches were recorded yesterday in the corridor, mostly surface sluffing and the occasional size 1 wet surface snow avalanche on SW aspects.

    Clouds in our zone around noon yesterday afternoon.

    Moisture sliding down from the North.

    Moisture on the way for Monday afternoon.
