I think what kills me is the snowflake size this storm.

 

If we lost out on accumulations due to lack of QPF, I could deal.

Temperatures too warm? I could deal.

 

However, we had ideal temperatures for snow ratios and hit the higher modelled QPF projections. What screwed us? The damn snowflake type of all things. Plates, plates, plates, dust and glitter. What makes a storm fun to watch are those big fat white flakes. This is why wet snow storms will always be my favourite. That cement snow is just crippling and so gorgeous.

Did cold temps reduce flake size?

My guess is that due to the continual dropping of temperatures, the cold air winning over was much more stable and inhibited vertical motions which are essentially for fatter flake growth. Hence why we only saw those big flakes during the highest radar returns this morning where motions permitted great flake growth.

Surprise, surprise. My storm total is likely 25 cm. North and eastern sides of my property averaging 22 cm, south and west sides with 33 cm. Given there was 3 cm on the ground prior to this event, this averages out to about 24.5 cm. I also noticed that most of my wind sheltered spots had 25 cm, and essentially every elevated flat surface seemed to have 25 or 26 cm. My snowboard was a total joke for this event so I didn't bother with it.

Great storm in my opinion. I'm at work, but would estimate I got around 20 cm. Amazing snow band this morning. EC really dropped the ball on this one.

As usual EC screwed up lol. But yes a great storm. Certainly not epic but it's nice to have big snow banks again to look at.

So the Euro shows another EC special later this week, lol. 

 

SONT does get some snow though from the northern stream. Widespread 8-10cm. 

 

Great storm. Had to go to school to do my test. Took me 1.5 hours to get there but got there in the nick of time. Just finished my test like 10 mins ago. Now to head home.

Hope you did well on your test. What school do you go to?

I know some people seem a bit down about the storm but I think its rare to have widespread 20-30cm across such a large area of southern ontario. Personally this is the biggest storm I've seen in years. (I was away for a majority of 2013) so I give this storm an A.

Agree. Hopefully this storm (along with the clipper from last Thursday) ushers in a snowier pattern. Based on today's 12z guidance, it looks like we may have more opportunities to add to the snowpack with very little melting.

Ryerson. And I did good, thanks for asking. I studied while I tracked the storm haha.

Euro has a potential storm next week.

York and ryerson were opened today for some reason. I had a test as well but I have a snow day.

Yeah, looks like the heftier QPF verified, but we couldn't lose the pixie dust. I thought we'd start out like that but when I woke up a 5am and it was still spitting those grains, I knew any notion of anything approaching the SREFs was lost. I thought anything north of 20cm was lost too, but we managed to pull it out. 

 

The death band stuff was 20:1, but if you averaged this storm out I'm guess the SLR is something like 12-13:1.

Just got home. Alot of roads are empty as people decided to stay home. Here's the text output for the 12z Euro for the storm potentials later this week. It shows about 1-2cm generally Tuesday night-Wednesday and then shows an additional 8-15cm come Thursday. The second wave will need to be monitored. 12z UKMET also showed about 10cm for the GTA.

0.05 qpf for the clipper and 0.30 qpf for the Thursday potential. The 12z GGEM is also decent. It shows ~5cm. With the cold temperatures in place, ratios could be in our favour.

I'm guessing YHM uses a nipher too. 

 

And I'm guessing YYZ comes in around 15cm.
