December 2023 Forecasts and Discussions

Latest HRRR. This won’t happen, but still.

Seems realistic, no?

Looks like higher hills getting 20 cm, but divide that by 2 to reflect the wet snow ratios, and divide by 2 again to factor in rain mixing in and mild ground temperature, you're looking at 5 cm of slush on higher hills.

And would you look at that - 15z HRRR snow depth output says exactly that - 2-5 cm at higher hills!

[Bonovox]

Not sure I agree. I've seen lots of people post stuff like "models said I would get 10 cm...only 2 cm on the ground... Bust!" When in fact, it was just them misinterpreting the model output...

I would disagree with your assessment.

Cold rain. Looks like it's getting heaver so maybe we'll see some chunkiness soon.

Edit: looks like SFU skipped the rain phase entirely

[Rubus_Leucodermis]

2.9ËšC and falling. Splat test: positive.

2.9ËšC and falling. Splat test: positive.

Oh you're splat test positive already? I'm not quite there yet.

[Pomoman]

Snowing quite steadily now. Light frosting of snow on branches and grass already.

Yes, and hence why I posted this...

I think places above 100-200m will get a quick 2-5cm this afternoon before it transitions back to rain.

Look, we're going to post outlandish 10:1 ratio maps whenever we have events like this or not. That's part of the fun and most people enjoy it. Maybe you don't and that's your right, but it isn't going to stop the rest of us from having some fun.

Looks like snow line about 250m with splat going to 100m in Abby.

Splat at 150m here.

[Abby_wx]

4C here with moderate rain and the wind coming from the southeast which isn't helping matters.

[Bonovox]

Cold rain and +2.6c in North Delta.

[VanCitySouth]

Guys I think my rain is defective. It's not getting chunkier.

[Typeing3]

3.5c with drizzle here in east Coquitlam.

Light flurries on upper Westwood plateau as of 30 minutes ago.

[VanCitySouth]

NEVER MIND, WE HAVE CHUNKAGE.
SO IT BEGINS!

[Bonovox]

Cold rain getting colder now. Temp has fallen to +2.3c.

[Catnip]

Starting to switch over to here.

No expectations though.
