The upper level ridge will bring mostly sunny skies to the area today with a Northwesterly onshore flow. There is still some scattered high cirrus cloud but it should burn off by this afternoon. The FL is just below 4000 meters and there is a slight inversion. The high pressure will  persist into Tuesday before a rapidly approaching upper trough pushes in from the North by Tuesday night. We should see come cloud development Tuesday afternoon and there is a chance of some precipitation early Wednesday morning. The FL will drop to 1500 meters by Tuesday night as the trough moves through, with some moderate/strong winds in the alpine. Wednesday will be mostly cloudy with some scattered showers and the FL will gradually rise back up to the 2500 meter range. Unsettled weather for Thursday as the trough moves East and a ridge begins to build for the end of the week.

    Upper trough will bring some cloud for Tuesday evening into Wednesday.

    Ridge rebuilds for the weekend.

The upper ridge will strengthen today in a Northwesterly onshore flow. Mostly sunny conditions with some cloud development this afternoon. The FL will rise to about 3600 meters. Victoria Day will also be warm and mostly sunny with a few clouds, the FL will spike too almost 4000 meters. Tuesday begins as a sunny day with some cloud development and cooler temperatures Tuesday night as a weak upper low moves down from the Gulf of Alaska. Uncertain at this time where it will track and how much moisture will accompany it for Wednesday. Going to say unsettled weather for the later part of next week. Monday is the last daily post until next ski season. Will be sporadically posting during the summer when there are avalanche issues and topics to be discussed. Not sure as to the future of this blog as it depends on sponsorship and how many people are willing to donate to keep it up and running. There is a donate button on the side bar!! I am organising an Avalanche Awareness Seminar this coming October, the dates are the 27Th and 28 Th with the venue at the Chateau Whistler. Looking for sponsors and exhibitors to pay for this event. Please go to www.aawsome.ca for information as the summer progresses.

    GOES IR image from this am.

    High pressure for Sunday.

    Flow for Sunday into Thursday.

    High strengthens Sunday, FL rises to 3800+meters.

    Looking nice for Monday.

    A weak upper trough pushes in from the North on Tuesday. Expected cooler temps Tuesday night.

   Weak upper trough for Wednesday will bring unsettled conditions.

Wedgemount area - stay off of Wedge, Parkhurst, Rethel this weekend. Avalanches started at 
10:30 am and didn't stop all day. I heard no less than 10. Back of the lake has a big one. 
Snow line starts at 1100m (basically 30 min up the trail). It's boot packed all the way up now 
and the lake is still frozen. The glacier is in excellent shape and fully filled in but cornices are 
EPIC. Also saw big cougar tracks.

    Blue Bird Saturday morning.

    You can see were the dozer is cutting in the road to the Peak.

    Fissile Mtn.

    Clouds in the afternoon.
