Today is the 5 year anniversary of the "Wall of Snow" storm. Wall of snow because once returns hit a particular location that day, it basically started as mod snow or worse. Ended up with 7" here.

LAF obs for that storm: http://www.wundergro...eq_statename=NA

And to show how far we've come, I recall that storm thread over at Eastern may have been a total of 3 or 4 pages. Now we get 1,000+ reply threads before storms enter the country. guitar.gif

Beavis-

I have no idea how they make that map considering more then half the lake has been cloud covered for a long time (due to cold air forming lake clouds). From looking at Modis from yesterday, i would guess most of the south end of lake is between 43F-46F... away from the shore.

take a look for yourself:

Jbc-

I noticed the same thing. I'm so far below right now, that we would need some very warm temps to even bring us anywhere near normal and by looking at the GFS... Holy crap..its basically more of the same and is very similar to what the 6Z showed.

I really expect a reversal in January, but who knows....

I don't expect anything like December 1989 (although if the GFS was right, the mean would end up colder than even then) followed by a January 1990 style reversal. Those kinds of flips are pretty rare, but January would probably be warmer than this, but that doesn't necessarily equate to above normal either. Let's say the average temp for December was 6 degrees below normal. A much warmer January could still end up being normal or either side of it and we'd still have decent chances for snow.

'89 came in waves starting the last week in NOV. Each wave was progressively colder. The peak was a few days before xmas, (-17 or something). I remember it snapped the week between xmas and new years and the turn around was amazing. I believe we didn't see a flake of snow again until a mini-blizzard squall line came thru in late feb with an arctic front (by the way that squall is still the heaviest 2 hours of snow I've ever seen in my life).

Yeah, if you look at the maps back then, the dump of arctic air around Christmas pulls out and the pattern just collapses and goes all zonal for just about the entire rest of the winter. Very unusual, and has never happened before during another winter that I've seen. Maybe 2005-06 comes close? Both winters are considered ENSO neutral by CPC.

Yeah, I remember that one. Maybe a bit over 5" here but some nice TSSN. Too bad it was a quick mover.

That's about the amount of snow I'll see in a somewhat above average winter. :arrowhead:

They took some of the reports out, but the northern suburbs of Toronto picked up 1-2 feet. Even around Highway 7 there was over 8". Really unusual how deeply inland this event penetrated.

I think it's a bit niftyl that some of the snow bands from Lake Superior extend all the way down into southeastern Michigan and southwest Ontario. Also, look at that band that was coming in near Erie, PA. That one extended down to almost West Virginia!

LES affecting areas 50-80km southeast of Georgian Bay really doesn't feel that impressive after seeing what I stated above... but what do I know? :whistle:

I can assure you that those types of amounts are atypical for the GTA. Those streamers extending into WV are due to a) favorable orographic conditions and b ) as you said, the fact that two, and sometimes three of the GLs are in on the action.

I remember the "wall of snow" storm on Dec 8/9, 2005. Had 6.8" imby, best of the 2005-06 season.

Meanwhile, while I was at work (of course) we had one of those popcorn squalls give a very heavy snowburst, dumped 0.2" imby, first time more than 0.1" fell at a time lol. It has compacted though. The weekend is still so in the air its ridiculous, so Im really more focused RIGHT NOW on tomorrow nights clipper.

Snowfall in Lucan north of London is now 167 cms or 66 inches since Sunday. According to my employer. the majority of people went to work yesterday, despite the conditions, so now I have to make up the time, use vacation or no pay for the day.

I guess you only get to stay home for a full-out Env. Canada warned blizzard. :axe:

Wow, already down to -8 in Sterling. -6 in Rochelle. Only 2 here. Not sure why Sterling is so much colder than here since we're very low in the same valley. Usually have very similar temps on nights like these. Maybe it's because they're more centrally located in the main snowpack.

Aurora's slacking...only -2
