100/102 (*) Open Trails.
Great Chances For Fabulous, But Some Chances That
In Specific Instances, We Could Be Wrong.
There are some Wild-Card Scenarios Out There This Morning...
----------- 8:55 A.M. Field Reporting Insert Update: -------------------
Our forecast assessment of generally great groomed
conditions, but with some icy overtones at lower
levels due to yesterdays heat are basically correct.

Compared to recent weeks/months, blissfully easy...

Consistent with our conditions forecasting, upper portions
of the Mountain are very fine with very few glitches and lower
portions are showing the firmness and some icy bits as
the consequence of overnight cool after yesterdays warm,
However... With good sharp edges any of the variable challenges
in the lower sectors are all very easily managed.

Conditions Notes:
In The Groomed:
Given that the Base levels did hit +4C yesterday...
Where freshly groomed after the drop in temps
to back below freezing, extraordinary smoothness
over a very well established base that has close to
zero icy bits in the substrates.
There may be a secondary sub-group designated
“recently groomed” where the situation could be
far more complex due to the rise in temps yesterday
that saw the Summit exposed to +1C for the first
time in many weeks. If/where that is the case there
could be additional challenge with the overnight
refroze.
We could be wrong and it might just be one of the best
front-side groomed days of the season(see below).
In The Sous Bois/Hors Piste/Glades and Un-Groomed:
Complex and very individualistic challenge and hazard due
to the brief warm burp in the temps which may have made
things a bit on the chunky side with this mornings -6C.
Generally:
There is some chance that we could be wrong in our
conditions forecasting because it is possible that the
blip up into “warm” was not enough to overcome the
established cold in the surfaces to any great degree.
We call this possibility “Thermal Momentum” and in
this case it is sustained by convection where cold sinks
and heat rises. What could make us wrong then is that
the surface boundary layer of air chilled by the super-cool
mass of the Mountain washing down over the trail surfaces
may have been sufficient to prevent and significant warmth
from touching the surfaces. If so, this would be unique to
the kind of tipping points that can occur with “+” value
air temps that are only a degree or two over zero.
If there are any wild-cards in all of that, they would be the
variations possible over the vertical rise of the trail network
where base levels did make it up to +4C.
For all these reasons we stand by our Equipment Caveat
from yesterday where we encourage one and all to have
recent, sharp, edge tuning from this point forward over
the remainder of the season.

Bring Back The Memories... 
Research Future Visits... If you would like to look up dates you visited Tremblant, or you
want to research days/weeks/months to visit, you can sample what
they look like historically, month by month, year by year.
When reviewing dates from any of the past, numbered, archived pages,
you can use the "Previous Topic" or "Next Topic" buttons, located
screen far right, in upper date/message bar to scroll through sequential
dates, or use your browsers "back" button to stay on the selected index
page for non-sequential date reviews in either forward or reverse order.
There are approximately 6, 25 day Index pages per season.
If you “Bookmark" the link above, it will always take you to theFirst index page with the latest posts. That gives you an immediate,
current to 25 day past, review scroll of Winter Alpine Conditions by
consecutive date.
