    Early morning light Thursday morning.

    Above the mid mountain cloud layer.

    Dense dry powder on the Horstman Glacier.

    Soft cord.

    Into the moist cloud, mid mountain cloud layer lifted to just above the tree line in the am.

    Eventually the mid mountain cloud layer dissipated near days end.

    Thursday afternoon.

    Cumulus cloud development, there were even a few sporadic flurries.

    Later in the afternoon.

    After sunset, which was at 19:47 Hrs.

  660 meters    +3, Valley Temp, Max temp Yesterday was +14.3, 0.0 mm of precip recorded yest

   As of 07:00 Hrs this am we have overcast skies & variable visibility. Snowing lightly.


A warm Pacific front will bring light precipitation to the area today in a Southwesterly Flow aloft. The FL will hover at around 1800 meters, dropping tonight to around 1000 meters as a trailing cold front pushes through.  Unfortunately the bulk of the precip will be South of our zone but maybe that is a good thing. A break between systems early Saturday morning before the next frontal band reaches our zone with light precipitation into early Sunday morning, with the FL hovering in the 1400 meter range. Some models have unsettled weather slated for Sunday but there is no consistency or agreement in the extended forecast. Time will tell, more on that as we get closer.  Going with unsettled weather with some showers in the mix. This pattern will likely extend into early next week. Guesstimates:10-20 cm in the alpine by Saturday morning, 10-15 cm in the alpine by Sunday morning, 5-10 cm by Monday morning.
