15z RAP has a nice band of 12-18” in northern IL with it still snowing at the end of the run. 

Honestly concerned about the state roads could be in tomorrow, with lots of people traveling home or back to school it could get real dangerous or even impossible to travel. Even half of what the euro is showing would be bad. 

Still think it’s overdone, but impressive to say the least 

Euro is big again

Indeed, but am off tomorrow. Will be home to enjoy this one. 

 

Which is nice... there are only so many hours I want to spend babysitting “drivers in ditches” 

Yeah, and with college kids returning tomorrow in droves, you’d be more than busy lol

RGEM south, with absolute rip city over central LOT 

It’s like a smaller version of the euro, but similar amounts. Looks like a bullseye over Dekalb. You work in Syacmore right?

Looks plausible that there could be a narrow swath of 12”+ amounts. 

06z NAM looks a little stronger/slower with about the same placement.

Nothing like a bigass area of 40-50dbz rippage. 

The 36 hour hrrr has ratios of like 5:1 in that band lol. But it’s the 36 hour hrrr so..

This would be a complete holiday travel disaster. If the euro or any of the stronger solutions panned out many roads would be impossible to drive on, and the airports would be a mess. 

Guessing winter storm watches will be extended a bit south with the overnight package..

Euro is coming in hot..and staying put 

Edit: N IL is buried..

I have a hunch the GFS will cave and come south, atleast a little by 12z. Looking closely at the GEFS snow accum. mean, it did bump south ever so slightly. 

00z NAM is south, and maybe a touch weaker.

There's an 18Z euro? 

It’s a new feature I believe. I didn’t know about it until a few weeks ago I saw a tweet about 18z and 06z euro runs, and I looked & sure enough. 

Also, here’s the HRRR at 36 hours out. Not worth much, but just taking everything into consideration at this point. Definitely further south

18z euro 

It looked north at first but in reality it’s pretty similar to 12z.

I think I'd still rather be north of I-80 in Illinois, especially with eastward extent. Sometimes you get the either/or solution to work out but very often it ends up in some varying degree of model compromise, and a compromise would put the better snows north of I-80 in LOT's area.

Yeah I agree with that, I think the heaviest will definitely end up being north of I-80, if I had to guess now I’d say it’ll probably be centered somewhere near I-88 actually. 

Euro still well south. Centered around the I-80 corridor in IL and the IA/MO border roughly. 

New NAM looking very nice for much of LOT. 

06z NAM crushes the IA/IL border into southern Wisconsin  

Apologies if this has been said already, but this storm could be even more impactful due to the fact Sunday is a huge travel day. 

Wow at today’s trends. Huge south shift. Wonder if it’ll continue or if things will correct back north 

At first glance it looks like 00z NAM is further south a tad
