FWIW the 18Z NAM still shows widespread snow Sunday...a few inches.

12Z GEM is chilly and shows 13cm of snow for Abbotsford Sunday.

Much improved NAM run.

Much improved NAM run.

We should also keep in mind those totals are based on a 10:1 ratio. Temps will be hovering around 0c so ratios will likely be closer to 5:1 or even less during the day.

Absolutely.

[Bonovox]

Models have been pretty consistent in showing surface temperatures between 1-2c, 925mb temperatures of -1 to -2 and 850mb temps of -4 to -5. Not much wiggle room there.

Perhaps Kuchera maps would be more useful this time around?

That said, the NAM and GEM shows the snow late in the day Sunday and in the evening, so that will help.

Equivalent to how many inch if the ratio is 5:1?

[Storm]

Much improved NAM run.

It's not even finish with the precipitation at that hour

[AbbyJr]

There is a little something else going on which may bring something exciting next week. Yes, it may involved more snow, perhaps a lot. Keeping watch on it. Bellingham should do well with this storm as well.

Can you explain what that little something is?

I made this graph using 5 different climate databases to see how warm 2020 was compared to other years. Turns out it was a hair below 2016 for the warmest on record...

18z ICON is much better as well.

Look at all those red lined since the 80's. Gross. Looks like we need to go back to 1910 for nice cold blue lines at their max!

Woah, you are right.

I can't get a better image though. Bono can I think?
