For the forecast, a very weak frontal band moved through this morning with rain falling from 05:30 to 06:30 with accumulation of .9 mm at 1550 meters. The upper ridge will slowly build again this morning bringing unsettled conditions (mix of sun and cloud) by this afternoon, with freezing levels rising to 3500 meters. Wednesday is looking unsettled in the morning, clearing off in the afternoon for warm sunny conditions as the dry warm upper ridge moves into our zone.  Thursday starts off unsettled, the ridge is expected to slowly shift East allowing moist clouds from the approaching upper low into the area by the evening with the possibility of showers in the evening. Friday as of now looks unsettled with rain showers through out the day, prior to a stronger marine push of moisture into Saturday. Freezing levels should peak out at 3700 meters Wednesday, slowly dropping to 2300 meters by Friday evening.

    As of 08:00 hrs in the alpine there is high cloud and unlimited visibility.

    Clouds will move East later today.

    Looking moist for Friday.

Hey Wayne,
We did a "valley start" Spearhead yesterday.  We started a little late and because of that we saw some warmer temps out near Iago than we had hoped.
Dropping off of ridge crest onto the Iago Glacier (from the Macbeth Glacier) we encountered nice corn near ridge crest, but it suddenly transitioned to some frightening knee deep isothermal snow about 30m down.  Nothing propagated, but I released a lot of wet snow as I did a descending traverse.  I think a light breeze was helping preserve the crust closer to ridge crest.
This made me worried for descending from Iago, but we found nothing but nice corn all the way down to the glacier.
High sheltered North facing slopes were very winter like and had about 40cm of snow sitting on a crust.  The bond to the crust seemed OK, and the snow had formed a wind slab.  The Overlord traverse was frightening.
Steeper north faces had evidence of skier produced sluffing, but no slabs.

No pictures uploaded yet, but I thought I'd pass along the info.
