Actually there is an interesting reason why no hard to remove ice buildup appears when there is snow. When frost accumulates, it is fine and can adhere to the surface as it gradually accumulates and covers the surface so it becomes a dense layer. Snow on the other hand is obviously non sticky. they are large and too air-filled to adhere to the surface so they wipe right off.

Same reason why a bit of snow before freezing rain might help undo the freezing rain's ability to adhere to the road and cause slippery conditions.

So yes, I will try to make it snow all the time for you! I already made some wishes come true this year ;)

Keep your car in the garage overnight. No fear of frost or ice. Frost/ice occurs becuz of varying temperatures. It doesnt have to be extremely cold to create snow. Once snow hits your car it melts becuz ur car isnt as cold as the snow or colder. If the temperature swing is small you get no frost/ice come morning. But if temperature swings are greater to freezing levels as expected during winter wind chill mornings, then yea... that dampness freezes causing frost/ice on the car.

Car cannot be parked in the garage as it is filled with other vars.

Can't you technically just use a car cover? When you consider how simple it is to put on and put off, that takes away from all the effort required for scraping and the reisk of damage by scraping. you could try it if you are willing to search at Walmart or Canadian tire or something.

It should solve the whole problem of scraping car I think. It can also prevent the bird poop from getting on so it kills 2 birds with one stone, pun intended ;)

Looks like every single source I have agrees that the cold trend will run its course in November then go away for December. I did say it was too uncertain in the long range to comment on December a while ago while I knew November would surely be cold which indeed turned out to be correct. Now I have enough info to confirm December won't be cold like last year. This year does appear different than last year in that we don't have this solid model support for terrible cold in all parts of the long term forecast. Now models have warmer than normal temps coming in at times in December and also just normal periods. So this will not be a deep freeze winter like last winter.

EDIT: for now, I did notice that environment Canada has Toronto in a steady trend of at and below freezing days starting after tomorrow. So any snow that comes won't go away for a while cuz new snow will keep falling a bit and it will be too cold for it to melt, even though winter is more than a month away! Again, enjoy this winter scene while it lasts, cuz the above long range update about the warmth will make the current cold a distant memory.

Interesting to note, it seems like years with an isolated incidence of super early snow most often feature delayed winter. So earlier than usual snow was followed by a whole month devois of more snow. Last winter our first snow waited patiently till several days later in November, but when it finally came, we got into winter much earlier than usual and once our first snow came, we kept getting more winter. The same thing happens with summer, but in reverse. I noticed that when we got 30 degrees unusually early in April, the rest of the spring was crap and not worth the early 30 degree day and when we waited for hot weather to come, once it arrived it was good and the full fledged summer weather was not too late.
ah the good ole days when the OP predicted a warm November. Weather, you are so unpredictable

I remember that and remember actually what made the whole thing and this is rather interesting I did discuss it earlier. We were on a path to a warm November and all signs pointed to it. THEN, that typhoon made a curve and did this phenomena with the jet stream buckling. Almost like a damn breaking and tons of water filling into an area. Like water, cold air is so heavy so once it was unleased, it got stuck there. So the cold that was unleashed by the typhoon stuck for the rest of the month. And there went our warm November! Now its effects are wearing off by month end. And we are yet again on track for warmth in December, IF and I mean IF another typhoon does not recurve the way this one did. If one does, then we will have to go through the whole thing all over again with a typhoon wiping out the warm month lol

A quick lesson on winter dynamics. TWO things can randomly come up any time during winter and make an anotherwise warm patter suddenly change to cold on us. First is this typhoon thing which obviously starts to wind down as winter gets going, and the second one is "sudden stratospheric warming" Through a complicated process, the stratosphere warms up in a sever way with heat being forced up into that level of the atmosphere and this forces all the cold to splatter onto the surface and invade areas like Ontario, kind of like how the warmth was forced into the arctic, also unleashing cold FROM where it was supposed to be TO where it should not be which was our home region.

Both these things can appear at random times in winter and a forecast that was supposed to warm can be thrown off into the freezer by one of these. It seems climate change might be making these things happen easier, because when typhoons and other things buckle the jet stream, it happens in a much more profound way than it used to. They just said this was historic cold for the US that came from this one. Didn't we have that last year too? Seems like more than a coincidence to me. Must be the new norm for nature to exaggerate unusual moves in the jet stream.

Keep in min the new update I just made. There are signs this cold will be replaced by a mild trend. If this switch can be confirmed this week, then you won't be needing anything for winter until Christmas break. We will have to wait and see, but right now it looks more likely than not that all this will be going away on us again till the normal start time for winter. Watch out that this is el nino. We stand the slight risk that things get stuck ABOVE normal even. Again, we must wait and see how things go.

I just looked outside its still snowing with no sign of letting up. I want it to stop and everything to dry up, my car is in my garage all nice and clean I don't want if getting filthy when I go out in the morning. Never mind my nice clean floors in the house all the wet filth that's going to get tracked in. Its just to early for this.
