Yeah, that was a disgrace. 21cm for Jan 2-3 or something. Buttonville had almost 60 IIRC :lmao:

60 cm of snow for a storm is something we all could sink our teeth into, it would be nice to have something like that soon. Do you have a short list of the greatest snow storms for Toronto in terms of snowfall amounts (not from the usual lowballing station, but Buttonville or otherwise). A radar loop of that one could really add meaning to the profound nature of it as radar does for severe events.

 

After the ground blizzard which I wanted to post more about, there was a 130 pound chunk of ice in an oval shape at the end of the driveway. It was 3.5 feet long by 1 foot. That's another first. Overnight Friday into Saturday another 6-8 cm fell.

 

About the UW weather station, why do I get the feeling there is a wall at -30ºC? Everytime I've checked during an extremely cold night that the temp. really plummets, that station stops just sky of that magic number. Its always .7, .8, or .9 of 29 degrees since at least 2005 which I read was the last it went below that. Something might be up, its not the first time problems have occurred with it (summer of 2012 it was screwed). The other thing that bothered me was I read somewhere on the site (that shows the data) that this current winter was above normal for temperature...something along the lines of "believe it or not, its warmer than the average" and I thought that was a joke. I can no longer find that statement anywhere on there...

dmc is lurking! Could you post that Toronto snowstorm list? I don't know how I haven't saved it to my hard drive.

Should be pretty easy to beat last weeks coldest temp tonight(-19c) although 850mb temps likely wont end up being as impressive the snowpack is fresh, deep and winds are light. Feels as close to mid winter as ever outside.

 

lol at the 6z NAM. Tries to bring the -30c 850 isotherm over us by 84 hours. What a winter.

Found it.

List currently doesn't include the 14.4" that fell on Toronto on February 8, 2013.

North York currently at 140.8cm for the season (not counting last night's snow). Buttonville's at 154.5cm (including last night). Estimating, downtown's closing in on 130cm. I think even downtown has a legit shot of finishing the season AOA 150cm. That's usually my threshold between a B grade and an A grade. Considering, the cold, the snowcover, and a couple of decent storms, I'd have no trouble upgrade this winter to an A- if the U of T station can add another 20cm or so.

My numbers pretty close to the North York Station as you can see in my sig. YYZ still the lowest among all the other stations at around 110-115cm for the season. The Nipher is partially to blame for the decrease in seasonal snowfall averages IMO at YYZ. 

 

If the PNA can relax a bit and trend towards neutral, we can get some decent gradient type storms and perhaps achieve another 10+cm for the season.

Not even, they're at 109.8cm (although you can add a cm or two to that from this morning).

 

As to your second point, I don't think so. The decrease from the 1971-2000 to 1981-2010 averages were as follows:

 

Pearson decreased by 5.7% (115 to 108.5cm)

Downtown decreased by 8.9% (133.4 to 121.5cm)

Thanks, that's great.

 

If we hit -25 tonight it'll be the 4th time since 1914 we've done so in March. EC forecasting -26 with a wind chill of -36 tonight

That windchill is insane for March, truly brutal if it verifies. I don't think we have a good dataset of wind chills in general but if we did then overnight tonight could be a top player in history. Another contrast for you guys, 14 years ago this upcoming Saturday (March 8) it was 24ºC at my location and nearly 28ºC in Windsor ON.

Don't think YYZ can achieve -22C tonight. The temperature warmed from -17.2C at 12am to -16.3C at 1am. -_- The Temperature would have to drop 6 degrees per hour from now till 7am to achieve that.

If it dropped 6ºC per hour from that base temperature then it would be -52.3ºC by 7:00 am. I think you meant 1ºC per hour as 6ºC would achieve that and then some! :lol: I'm disappointed in these warmer than forecast temps.

Today marks the 11th anniversary of what is still the coldest temp of this century at YYZ. -24.7c. Won't come close to that today. In fact, as cold as winter as it's been, I don't think a single daily record was set at YYZ for minimum temp. Someone correct me if I'm wrong.

It got down to -12.8c on Nov. 24th, 2013, beating the old record of -12.0c set in 2005.

As of 7am, YYZ is at -19.4c and downtown Toronto is at -18.2c.

Haven't check in much lately on the models etc. but I've been keeping up with the threads, been busy with the band.

 

Total 6.0cm from Saturday night's snow. Not bad, a nice refresher.

 

Persistent cold temperatures have been amazing, enough said there. 14 degrees C below normal for a high temperature today is quite incredible (average high +2C). Could be the greatest temperature departure of both 2013 and 2014 so far?

Also 1.6mm of precip was recorded yesterday at YYZ.

Interesting how Toronto has consistently been warmer than forecast when it comes to overnight lows for the past month. These cold outbreaks have lacked the punch of the January 2 and 22 outbreaks.

Interesting storm in the D8-D9 period. Ridge axis looks supportive of a storm cutting throught the interior northeast in this time. Liking the fact that there are several impulses moving into the western conus(active STJ) so the potential for phasing is there. The ec ens mean also has a mean of ~6" of snow for YYZ.
