Yeah, like I said it's more north (closer to 5") versus south (closer to 2").

Our snowdepth at 84 hour on the GFS is 2-3" and 3-5" further north, not including our current snow. It disappears after 90hr.

Yeah after I looked again it looks a little better for an inch or 2 or tree north if all the stars aligned right (good luck) in MI. Gotta about 6 hrs and very little precip before it gets washed away.

Have we had any storms this year where there was just one area of low pressure? The flow has been so progressive with the Pacific spitting out storms and then there's been so much dry air ripping the storms apart. I haven't grown up in the Midwest, so maybe it's typical for that to happen in this area of the country? I thought the whole "everything needs to come together just right" was just an east coast thing. Still trying to figure out the climate in the Midwest...

This is just the nature of the weather pattern here. A lot of variability--all the different scenarios need to be considered here since there is a lot of potential energy waiting to be processed by the atmosphere. When you have two significant moving parts and an amped low level baro zone--these kind of flip-flops will happen--but if consideration of the environment is taken--then it isn't a surprise to anyone. This is why weather is so exciting too!

ORD ends up with 1.48" liquid with .67" of that frozen precip. that second sfc low really helps us in the snow department.

And completing another run of ridiculous model mayhem.....the Chicago-Detroit corridor either has everything from a dry wedge between two storms (GFS) to a regionwide massive snowstorm of 12"+ (EURO).

Yeah, no kidding. I suppose I'd be best served taking about a 24 hour break and checking in again tomorrow at this time, unless the thread reaches 50 pages before then.
