Chicago WX Posted February 15, 2021 Share Posted February 15, 2021 Happy that I'm a lazy government employee that gets to sit at home today (and get paid to boot) and watch this all unfold. The areal coverage that this event has and is hitting will be one for the books. 1 Link to comment Share on other sites More sharing options...

So do the kuchera weatherbell maps for the euro look the same and show the same amounts as the pivotal euro kuchera you just posted? Or are they usually slightly different?

NW tick which I is better aligned with the track of the 850/700 low. These Kuchera maps are dangerous because I think they're based on 17-18:1 ratios which is lofty but even if you shave 5" off those totals...sold!

Well, the Kuchera maps have been spot on with the snow down here, FWIW. They even pegged the snow amounts in San Antonio and Austin right. Link to comment Share on other sites More sharing options...

Furthermore, if the maps are based on 17:1 ratios, I know areas down south were hitting 20:1 ratios apparently, so it would make sense if those turn out to be correct, but of course, I'm not qualified to speak on whether that will continue up here.

My understanding of the Kuchera method is that it's a somewhat convoluted calculation of moisture content and lift in the DGZ. This is my first time hearing about the 17:1 ratio thing.

nwburbschaser Posted February 15, 2021 Share Posted February 15, 2021 Totally jealous of those closer to the lake. I think I'll be right on the edge of the heavier snow so we'll see how this goes. Link to comment Share on other sites More sharing options...

This is my first time hearing about the 17:1 ratio thing. Kuchera is actually really simplistic. You just take the max column temp below 500 mb, subtract it from -2 celsius and add it to 12. So for example if the max column temp was -12 celsius, you would do 10+12 so 22:1 ratios. 2 Link to comment Share on other sites More sharing options...

Ottawa Blizzard Posted February 15, 2021 Share Posted February 15, 2021 25 minutes ago, snowstormcanuck said: Let me know what you find. Given how rare 30cm+ storms are for us I doubt it's happened. '99 YYZ was using the nipher gauge so not even Jan 2-3 registered 30cm+ . Downtown Toronto came close with 38cm on Jan 2-3 and then I believe ~28cm on Jan 14-15. Thinking this one tonight will be the bigger storm of the week. Thursday-Friday storm looks like a quick coastal transfer and we're getting more snow scraps, maybe we edge out a moderate event. Anthony Farnell saying possibility of 40-60 cm (2 feet) total by end of day Friday, when you take into account both storms. Amazing for Toronto, if it happens.

RCNYILWX Posted February 15, 2021 Share Posted February 15, 2021 My understanding of the Kuchera method is that it's a somewhat convoluted calculation of moisture content and lift in the DGZ. This is my first time hearing about the 17:1 ratio thing.The Kuchera ratio is a linear equation based off the maximum temperature from the surface to 500 mb. So necessarily when it's very cold, the ratios it gives are high with no regard for the snow growth processes (DGZ depth, lift through DGZ and whether it's we'll aligned with DGZ, and how well saturated the DGZ is). That's the flaw of the method, since there's plenty of occurrences of low ratio pixie dust type snow in very cold temps. The Cobb ratio is based off those snow growth processes.
