Of course it is. Shwinagain lake, nanaimo, Catnips Hill, chilliwack, squamish, Hope. These are areas that score well. Other areas are picking up the scraps too often.
:roll:
If you are planning a move...
Looking forward to our first 3 day stretch of sun and 20c++ 8-)

Didn’t notice that one. The preponderance of models is indicating a snow chance on VI/Gulf Islands only. And light gray = flakes in the air at times.
It's called clown range for a reason.

06Z Euro had the same idea. Flakes flying, but not adding up to much.

Ouch, not good. Hoping it’s an easy fix.

GFS gets crazy in the long range. Also Operational is on the warm side as well.

So close. They have another hour or two to make the -15 true.
Actually this brings up a question I sometimes have thought about but never long enough to remember to ask. Would you guys say, for negative numbers, rounding up should be to the higher whole number (-14.5 to -14) or to the absolute number (-14.5 to -15)?

I don't know that there's a right or wrong but what's the preference here?

Personally, if you're rounding, I would stick with traditional rules. 0.0-0.4 would round down and 0.5 to 0.9 would round up. I'm not sure I would round either direction for scientific numbers like temperature though.
