Chicago Storm

3.4” at ORD. Hard to get a good measurement here with blowing and drifting, but came to an average of 4.0” .

2.2” here as of a bit ago. 1.6” ORD. .

LES affecting NE. IL now... .

Started as a bit of rain here at the start, before flipping to snow. Have a dusting so far. .

18z Euro...

LE already approaching the MKE shore in SE. WI.

Records going to go down again at ORD... Snowiest 11/10 is 0.4" in 1991. Snowiest 11/11 is 1.9" in 1995. It's also on track to be a top 5 snowstorm this early in a season.

12z Euro... .

~6” is looking like a lock around here. .

6z was even better. .

It actually wraps up a nice little wave now. .

HRDPS hits the LES...

GFS caves more as well. .

NAM caving hard now. POS American guidance. .

I’ll help you, with some 18z GGEM... .

RGEM nice too. American guidance going down, per usual. .

Basically foreign vs american guidance at this point. RGEM/GGEM/Euro/Icon all have an area of 2-5", locally higher. NAM is DAB, and GFS is pretty close to that as well.

11/14-15/1997 is another western shore LES event.

ok.

18z Euro with another step back.

0.1" at ORD and here last night.

GGEM and Euro took a step back. It's gonna be hard to get anything really good out of the setup, given where the main PV lobe is located up over the Hudson, combined with +PNA in place. The new 12z ECMWF/GGEM runs are probably the best case scenario. I'd hedge somewhere between them and what the GFS has for now.
