Chicago WX Posted February 6, 2018 Share Posted February 6, 2018 Going out with a bang with parachutes right now. Pretty awesome. Stacking up quickly, so probably going to finish with around 4" or so here. Not bad. Link to comment Share on other sites More sharing options...
Jackstraw Posted February 6, 2018 Share Posted February 6, 2018 Not a flake. LL dry air is entrenched taking its sweet time to saturate. Link to comment Share on other sites More sharing options...

hawkeye_wx Posted February 6, 2018 Share Posted February 6, 2018 There are now 9-10.5 inch reports coming out of the heavy band from southeast Iowa into Illinois. Link to comment Share on other sites More sharing options...

Lol, that’s pretty much what I was saying earlier today as the best returns slid to the south...but we finally got into the good stuff tonight. Just measured a little shy of 4”, though it’s kinda weirdly not uniform amounts as some spots have more in and around my measuring location. Regardless, the late rally is playing out nicely.

We're already at around 2". We got a nice initial thump with that thin band earlier and it looks like we'll easily see 4". The first overperformer of the year locally.

Yeah a buddy from work texted that they got over 9" about 30 miles south of here in Galva. The radar returns along that band were pretty intense looking for quite awhile. Can only imagine how hard it must have been snowing considering how heavy it snowed here under lighter returns. Had to be an awesome sight. In the end it seems like the NAMs and GFS were both right. The NAMs had the right idea with the band of heavier precip, but the GFS was pretty spot on with the placement of the heaviest totals. Euro was a tad too far north.

Snowstorms Posted February 6, 2018 Share Posted February 6, 2018 0z NAM and 0z RGEM both showing ~2-4" in the GTA for Wednesday's event. Its a close cut-off, but we could definitely see some deformation bands given the amount of moisture to play with and good ratios. Link to comment Share on other sites More sharing options...
CoalCityWxMan Posted February 6, 2018 Share Posted February 6, 2018 Still snowing lightly with just under 5” here. Looks like just south of me in the Pontiac area had some 8” totals from what I’m hearing. Link to comment Share on other sites More sharing options...

That dry air was stubborn as hell. Burned us Sat too. Super shiny reflective crystals, glad I'm not 20 at a Dead show, I'd be freaking out lol!

wisconsinwx Posted February 6, 2018 Share Posted February 6, 2018 2nd event in a row that met if not surpassed my expectations. Still snowing about four hours later than I expected it to start letting up. Let's continue piling up that snow! Link to comment Share on other sites More sharing options...

CoalCityWxMan Posted February 6, 2018 Share Posted February 6, 2018 Tomorrow night’s event could surprise some folks, the nam is hinting at some banding potential, could drop some decent totals in localized areas like tonight if it happens Link to comment Share on other sites More sharing options...

Blue is 0.5", and dark green is 0.25". That sweet spot from east of Ottumwa through Galesburg and over to Lacon had quite a few 8-10in reports. I got in the 4-5in range here. GFS going gangbusters tmrw night on a hefty band with that next system. Loving this pattern Link to comment Share on other sites More sharing options...

Yea I'm def excited esp since I only missed that death band today by a county. Lol. But for as late as the snow started here (5pm) it really added up quick. At least an inch per hour rates Link to comment Share on other sites More sharing options...
cyclone77 Posted February 6, 2018 Share Posted February 6, 2018 DVN finished with 3.9". Haven't seen anything from MLI as of yet. Looks like tomorrow night's snows will line up best from northern MO to northern IN. Looks like a nice little 1" refresher here. Link to comment Share on other sites More sharing options...
Justin Posted February 6, 2018 Share Posted February 6, 2018 Ended up with about 3" here around Prairie Du Chien. A bit of an underperformer but the duration lasted a bit longer which helped that total a bit. Link to comment Share on other sites More sharing options...

RCNYILWX Posted February 6, 2018 Share Posted February 6, 2018 ORD -- half-centing, pennying, nickeling, and diming their way.The forecast qpf from my office for there was pretty good, we averaged about 0.20" leading up to the event and it had 0.22". Yet again, poor snow growth/low ratios were a problem, with ORD ending up with 2.2" at an exactly 10:1 ratio. I had a feeling it would be an issue somewhere, but didn't think it would be as pronounced or long lasting through the event outside of the strongest f-gen banding, which turned out to be most of the metro had the lower ratios again. This shows the challenge of ratio based snow forecasting. When it's cold the maxT aloft/Kuchera method always assumes high ratios, often 20:1 or above. In reality it's obviously not that simple, with the location of lift through the DGZ and how strong that lift is determining supersaturstion with respect to ice, and these ultimately determine SLR. I'd bet if we were to plot SLR for this event, there would be a large area of 17-20:1+ where the highest snow amounts were (aligned with strongest f-gen banding) and climo (13-14:1) or less elsewhere. Had climo SLR been used for the metro, it would've been a good forecast based off the QPF. Link to comment Share on other sites More sharing options...

snowstormcanuck Posted February 6, 2018 Share Posted February 6, 2018 Can't get the southern stream to play ball this winter at all. Outside of that phantom storm in mid-January, I don't recall there being any other legit threats inside of 4 days. Link to comment Share on other sites More sharing options...

The f-gen band rolled right over us and I ended up at 17:1 (0.31/5.3") Link to comment Share on other sites More sharing options...
