james1976 Posted February 7, 2018 Report Share Posted February 7, 2018 Looks i get hit mostly from 1st wave. Luckily it dumps pretty good. IL is in the pivot area for all the waves. Models are consistent with that. Quote Link to comment Share on other sites More sharing options...
Jaycee Posted February 7, 2018 Report Share Posted February 7, 2018 Still ends up hitting Chicago lol They get hit with all 3 waves It's insane no?

Tony Posted February 7, 2018 Report Share Posted February 7, 2018 Still ends up hitting Chicago lol They get hit with all 3 waves High Pressure sends it down south of everyone though.I still believe that this last wave will be farther NW then what is being currently modeled. I know it's not a super strong wave but can't see it being pushed that far SE with really not that strong of a HP. Still a ways to go but thinking trends will be to bring it back north again.

hlcater Posted February 7, 2018 Report Share Posted February 7, 2018 Bad trends continue, this is going from being really something to a garden variety WSW. I'll still take it, but the trends of seperating everything and shunting it south certainly aren't good for us.

Tabitha Posted February 7, 2018 Report Share Posted February 7, 2018 How many times have I written that the GFS & CMC & ICON vastly overdo QPF beyond 72 - 84 Hours; especially with systems that have practically no upper level support; before they figure it out with 36 or so hours to go? It is an algorithmic flaw written into the numerical modeling that the model designers have never bothered to correct. It is almost like "how many times does a person need to be lied to before they figure out the entity telling the lies is a liar?" Quote Link to comment Share on other sites More sharing options...

Tabitha Posted February 7, 2018 Report Share Posted February 7, 2018 especially with systems that have practically no upper level support; It is a mathematical impossibility to get a major snowstorm (even in locations with large bodies of water adjacent...the exception being lake-effect...and that's not a synoptic storm anyway) unless the surface reflection of low pressure is replicated far up into the higher levels of the troposphere; i.e. the lowest level of the atmosphere...the level beneath the stratosphere. This is because in order to effectuate exceptional QPF totals; there needs to be lift, convection, rising air; sharp vertical temperature contrast between the surface and say 15,000 feet above it. This lift can only manifest when the storm is present at the 925 mb level, the 850 mb level, & the 700 mb level. This generates what is known as vertical motion; the process by which heavy snow is created. Without it; you are going to be left with pedestrian QPF totals; no matter where you are...on the Great Plains; or on the East Coast.

Tabitha Posted February 7, 2018 Report Share Posted February 7, 2018 Since 1884-85 / 133 years Chicago has about 10 storms greater than 15 inches; but all of a sudden they are going to get another; with an utter lack of upper level support.

I think you look golden and may be near the epicenter, if not very close to it. Just took a glance at the RPM model and it looks a lot like the 12z NAM 3km pounding Chitown and N IN into S MI. From what I'm seeing, this set up is looking very similar to the one we saw a couple days ago which had the heaviest returns on the southern periphery of the main snow shield. In essence, the ones who appear to be cashing in on the highest totals will prob be close to I-80 across N IL and about a county north of there. 1 Quote Link to comment Share on other sites More sharing options...

We're riding or dying with the GFS down here! Let's anchor this thing down. NAM has the 6+ amounts for Friday barely into IL though. That's got me a little worried as far as Friday is concerned.

GFS Kuchera says so! Whatever; let me now how it works out.We have a tight baroclinic zone and abundance of moisture which seems like we have plenty to work with even without upper level support. Every model suggests a high end warning type snows. Will it reach your 15" mark, I don't know but 12" at this point seems like a good bet. Just my thoughts for whatever it is worth. Edit: Forgot to add in meso banding. Wherever this sets up will get pounded on and possibly for a long duration in the same areas. 3 Quote Link to comment Share on other sites More sharing options...

jaster220 Posted February 7, 2018 Report Share Posted February 7, 2018 There’s another wave developing at hr 90 with a ton of precip breaking out in NE/CO etc farther north than 6z so far That's our problem, it's just a "wave" without a SLP reflected til it pops one off the EC. The arguement that this can't slide more E to SE (like everything has this season) is false thanks to this fact. What T has been harping on wrt to lack of upper lvl dynamics.

Jaycee Posted February 7, 2018 Report Share Posted February 7, 2018 Really dissolved quick around here. That D**n high pressure absolutely wrecks that second wave. I'm not confident we'll see more than 2-4" here either. Going to have to avoid this thread once storm time rolls in, it's going to be infiltrated by Chicagoans saying "14" here already and LES now kicking in and under a heavy snow band! This is turning out to be bigger than the GHD blizzard!", while we struggle with a WWA that doesn't pan out. 2 Quote Link to comment Share on other sites More sharing options...
