March 13, 2015

    A bit of colour at sunrise Thursday March 12, 2015.

    Fresh snow brought out those with fresh tracks tickets.

    Avalanche control yesterday produced mostly size 1-1.5 slabs 10-20 cm thick, easily triggered.

    Nice to see some snow in the trees again!! Read the local avalanche bulletin!!

    Just before sunset yesterday, a very cloudy day for the most part with isolated showers.



Weather Observations for March 13, 2015; taken at 06:00 Hours.

2240 meters     -3, Winds were 5-10 KPH from the SE
2180 meters     -2, Winds were 15-25 KPH from the S
1860 meters     -1, Winds were 5-10 KPH from the E
1835 meters      0, Winds were 10-20 KPH from the SE
1650 meters      0, no new snow, Base 144 cm
1550 meters    +1, no new snow, Base 107 cm,  Relative Humidity 90%.
  660 meters    +4, Valley Temp, Max Temp Yesterday was +10.1, .9 mm up to Midnight yest.

   As of 07:00 Hours we have high virus cloud and unlimited visibility.

For the forecast, expect unsettled conditions for today as the Southwest flow aloft and an upper ridge moving East bring increasing cloud during the day with some breaks earlier in the day. The freezing level will rise to 2500 meters during the day. A strong pacific frontal system will bring heavy precipitation to the area this evening with a descending FL ending up at around 1900 meters as the front moves onshore. By Saturday morning the FL should drop to 1700 meters with heavy precip in the morning easing to moderate precip by the afternoon with the system exiting the area Saturday night with a further drop in the FL to around 1200 meters. The models are in disagreement still for Sunday and beyond but will go with unsettled weather for Sunday with a further drop in the FL descending as low as 800 meters by Sunday night. Monday will start out as unsettled with increasing cloud as a weak trough moves through with light precip and a FL rising to 1800 meters into Tuesday. Guesstimates: 8-10 cm above 1800 meters by Saturday morning, 20-30 cm above 1800 meters Sunday morning--15-18 cm above 1500 meters for Sunday morning, with some light snow reaching the valley floor by late Saturday evening.

    Image from yesterday, high pressure did not quite build enough into our zone, a cloudy day yesterday.

    Big picture from yesterday afternoon, moisture moving in from the South.

   This mornings inferred image.

   Moisture heading our way for tonight into Saturday.

    Nam model for Saturday. Looks like the system will move through by Saturday night.
