Currently -16.3 @ the pond in south Sardis, overnight low -17.5

[Hawk]

It’s snowing right now

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.

If you are planning a move...

No idea, I haven’t looked at any models until this morning and saw this on the RGEM.

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.

Flurries not amounting to much but pretty to look at when it's -10. Quite Canadian of us actually.

I would take it.

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

Not sure about the mainland but when the outflow is going temperatures decrease with elevation on the island. The coldest stations on the South Island this morning were all over 100m elevation

Yes same here, we were at -20 at 900’ and it was -16-18 in the valley

Who’s ready for more SNOW later today?

Snowing here again, tiny flakes.

Water is frozen somewhere, nothing is coming out of the tap.

Global said 2 cm. tonight, I would think mostly for the western section.

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.

YVR did hit -14.5 at 5 am reading. Rounding up -15 officially.
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.
