Last night really busted, got no snow when it was forecast 8cm, then I didn't get much overnight maybe 1cm. Even the sun filtered was out at 830am when my blizz was suppose to be raging. It wasn't until 10am that the hammer came down and the wall of snow squalls started here with the lowest visibility yet this winter - 70m by 11am. As expected, at no point did I have blizzard criteria; heavy squalls for sure. It was cool how the LES started like a curl over Huron that pushed through like a derecho then the fire hoses were unleashed! Strangely Owen Sound or just south which was tap for highest totals hasn't seen muc,h its been south of Kincardine! Heavy snow on and off since.

There is an inland band north of Ottawa:

Now my area's wind chill of -4 today looks like nothing compared to -44 in Canada

minus 44 wind chill.gif

I saw Manitoba's temps and was shook to see the -40 windchills, I spot a -50 in Saskatchewan.

The LES bands are all north of me, they are getting smoked all over right into Central ON.

The downfall of December needs to be studied. 

This December so far has been cold and dry tho, very different from the mild ones. More than likely, the overall surplus of blah Decembers is probably just a run of bad luck, much like the recent overall run of good luck with Februarys.

The little wave which moved thru Central IL today significantly overachieved, local Met called for up to an inch today, I am sitting at 3.3” imby :D

That’ll hold me over for a bit while we head into the 40s with rain this weekend into next week 

It also continued over performing in north central Indiana.  About 2-3 inches here too.  Melting will happen tomorrow reaching mid 50s on Monday.

That’s what makes it even worse. If it’s going to be dry, may as well torch rather than feel miserable in the cold. Thankfully a milder pattern on the way.

Maybe for you guys further west it's been a cold December, but not the same story for us here further east. YYZ is running 3 degrees above normal for Dec. When the cold source is from Hudson Bay and Quebec than western Canada, that's when we average cold. 

But aside from the temperatures, it's been underwhelming outside the snowbelt regions. That seems to be the trend since 2017 and highly unusual for typical La Nina's. Wish we could experience the Decembers from 2000-2017 again. 

Are the averages on this from 1981-2010 or 1991-2020?

To each their own, Id take cold and dry over mild. The weather will likely continue up and down, hopefully it gets more active.

Averages are updated to 1991-2020.

And wow I didnt realize it was running that mild further east. Its been very underwhelming synoptic wise - nearly all of our 4.0" so far has been lake effect or lake enhanced. 

Call it a quirk or call it whatever, but the low snow Decembers have been very oddly persistant since 2018 for most of the region (with a few small exceptions). Again tho, we have balanced it out and then some with snowy Jan and/or Febs. Weird, but thats the weather.

We got 3" with that clipper in early December but everything else was lake effect too. 

The 1991-2020 average is arguably more warmer than the 1981-2010 average. Env Canada hasn't updated the 1991-2010 average on their page yet. I think the old 1981-2010 average in DTW is 29.9 vs 33.3 right now. 

I think the low December snow and warm Decembers since 2015 can be partly attributed to climate change. Unless this pattern is cyclical, but that remains to be seen. But given the amount of La Nina's since 2017 and the lack of cold/snow, it is highly unusual.

The current DTW Dec avg is 31.3°, not sure where you see 33.3°. The la ninas since 2017 have had more paltry Dec snowfall than usual, but also snowier mid to late winter than usual. Could be cyclical, not sure.

We lost power for about 40 minutes.  Tree branches have a good 1/4" of ice on them.  There is up to 3/8" in spots.  It's good that the icing is done.  We have finally crept above freezing and the precip is diminishing.

The worst icing was over southeast Iowa, where as much as 1/2 to 3/4" of ice built up on the trees.

More pouring rain, fresh off 2 useless days with highs in the teens. What a shit winter so far.

Lol we haven't exactly had any pouring rain. It's gross out tho. Cold light rain at 34°. And at least there's been some light snowcover and bitter cold for the Christmas season. Way better than torch imo, tho I know you disagree.
