Weather Observations for November 18, 2016: taken at 07:00 Hours.

2240 meters   -9, Winds were 15-30 KPH ESE --Horstman Hut

We could easily receive between 20-40 cm of snow at 1500 meters by Tuesday evening with the FL fluctuating from a high of 1600 m (Sunday) to a low of 700 m (Today). Cooler more seasonable temperatures should arrive by Wednesday in a Westerly flow aloft.

    As of 07:30 this am we have obscured conditions at 1835 meters.

    High thin overcast with low valley cloud at 2135 meters.



A brief weak  upper level ridge will bring clear conditions to the alpine this morning before another dry air mass with cloudy conditions moves onto the coast with a  weak frontal band expected by early Saturday morning in a Southerly flow aloft. Low level cloud will likely remain in the valley with an offshore low level flow.(some breaks) We are between the high and low.  Saturday should bring some very light precipitation with overcast conditions with a rising FL by the evening. There is a chance of some breaks Saturday afternoon.  The onshore Southerly flow will continue into Sunday with the FL hovering in the 1500 meter range with light/moderate precipitation. Models differ for Monday, we may see some breaks but likely to continue with light precipitation and a descending FL by Monday evening. Another frontal band for Tuesday with light  to moderate precipitation and cooler temperatures as the flow switches to Westerly by Wednesday. Will start posting daily as soon as the mountain opens. Hopefully with a clearer picture and accurate snowfall amounts on a daily basis!! More info on Monday!!

   Unsettled this morning with some cloud from the low moving onshore by the afternoon.

    Large low off the coast, weak high to the Southeast, low will eventually win with more cloud.

    Low off the coast with a Southerly flow aloft.

   Front heading our way early Saturday morning. should see lots of cloud from the low.

   Weak front on Saturday with the chance of some breaks in the afternoon.

    Sunday with a lull on Monday later in the day. More precipitation as the low starts heading NE.

   More snow and Westerly flow for Wednesday.

    Long range into Friday, looks pretty decent, cooler temperatures and snow in the forecast.

Thanks to Simon Thomson for the image and observations November 16, 2016:

Went out for a wander in Brandywine area today.  At 1750m, North aspect, we found a 200cm snowpack with 35cm of new sitting over a 15cm crust. All this overlying moist snow to ground.  Little to no wind affect felt in areas skied today.  Good skiing!  As seen in the profile photo attached, there's a huge contrast between the old and the new!


    The jet stream has migrated South bringing more seasonable temperatures in a Westerly Flow aloft.

    Roof avalanche on Monday.

    Monday just before sunset, 0.9 mm recorded at 660 m on Monday.

    Tuesday the snow line began its march back down the mountain.

    4.9 mm or precipitation recorded at 660 m on Tuesday.

    Unsettled Wednesday morning with showers, later in the day. "I Skied Fissile Like a Missile" PC

    1.5 mm recorded at 660 meters on Wednesday.

    Thursday morning the W/B weather machine producing cloud.

    1.0 mm recorded at 660 meters on Thursday.
