January 31, 2015

    07:30 Hours Friday; January 30, 2015.

    Some great light early in the morning.

    Lots of cloud to the North early Friday morning.

    Awesome cloud development Friday morning over Armchair.

    Clouds to the North but Bluebird looking South yesterday early morning.

    Surface Hoar where it can grow is liking the cool nights.

    Serratus was looking great mid morning with some last light opportunities.

    By mid day the clouds had moved in for a very cloudy flat light afternoon.

    By days end it was clearing off again.

2240 meters        -5, Winds were 20-35 KPH from the SSW

1550 meters         0, No new new snow, Base 99 cm,  Relative Humidity 70%.
  660 meters        -4, Valley Temp, Max Temp Yesterday was +4.3.

    As of 07:00 Hours we have mostly clear skies with a bit of high cirrus and unlimited visibility.


For the forecast, another clear evening with good crust recovery. The upper ridge is holding for now, but the offshore flow will eventually allow cloud into the area by this morning prior to the arrival of a warm front which will bring light precipitation to the area this evening and continue into Sunday. Freezing levels will drop to as low as a 1000 meters with a slight rise to 1300 meters by Sunday afternoon. The next front expected to arrive Sunday evening will be slightly cooler. Light precipitation from this front will continue into Tuesday morning with freezing levels hovering around 1000 meters. There are still major inconsistencies in the models beyond this time frame so more on that as we get closer. As of now it appears that a weak ridge will build for Tuesday afternoon into Wednesday before another warm front moves on shore for Thursday with moderate precipitation and freezing levels rising to 1800 meters. Guesstimates: 3-5 cm by Sunday morning, 3-5 cm by Monday morning, 3-5 cm by Tuesday morning.



   Satellite image from yesterday, cloudy in our zone.

   Big picture from yesterday, lots of potential moisture coming our way.

   Persistent high pressure will break down later today allowing a weak warm front into our zone.

   Steady light precipitation into Sunday.


   More light precipitation for Monday.

    Ridging for Tuesday evening into Wednesday.

   A fairly active and wet warm front for Thursday, still ? what this will do!
