GFS says "dry slot" to Cincinnati, but still 1-3 depending on ratios. If we could just get another 50 miles east...

Agree, very pronounced DS, we get all our snow from the frontal passage

I actually think someone is going to see some pretty strong fetch all the way down here from the lakes, depending upon how the wind direction sets up. Wouldn't surprise me to see someone stay in those backside snows longer than expected if everything lines up for them. Maybe a narrow stretch of a couple extra inches.

12Z GFS is a decent run in my opinion if you're looking upstairs and not at the surface maps. 6Z had a more broad closed upper low over the Ohio Valley at 516 DM, centered more over Indiana. 12Z run has the upper low more compact (stronger) at 510 DM centered over Cincinnati. Too bad we can't get it over the KY / TN boarder region. :lol: The upper low then deepens further to 504 DM over the PA / OH / WV boarder.

So far nothing in the 12z suite says to change anything in the forecast .

Great post! I checked the 700 MB Relative humidity maps from the GFS and that is correct. We do get the dry slot Fri morning. But, wrap around snows are possible esp N of the river on this run of the GFS and you can see that fetch off of Lake Michigan too. Just need another south / SE bump and this idea looks very plausible.

I completely agree. That 1-4" range is still looking solid with an avg of 2" looking highly likely for a lot of folks at this time.

The arctic front's front arrival I think has sped up a bit as well. Originally, I was thinking midnight Thurs night or shortly there after. It could be a couple of hours sooner if some models are correct.

I'd also like to mention that I don't think the rainy side of this system is huge either. I think most folks will see 0.10-0.20" of rain before flipping over to snow. Granted, it's still plenty of moisture to get the flash freeze going, but it's better then seeing 0.50 to 1" of rain and then flash freezing. That would be awful!

I'm still seeing quite a bit of spread in the 12Z GEFS members. The range of solutions are dry slotted with very little snow to the wrap around impacting us for a decent hit of something in the 4-6" range. Of course the 2" call is a nice blend right in the middle of the two extremes. Hopefully tonight or tomorrow we'll see less of a spread.

Great point Les, that would certainly lessen the effects

I wonder if the Indianapolis and Northern Indiana offices are contemplating Blizzard watches. Even the far Northwest part of ILN's area might warrant them.

Well, the Euro is pretty similar to the 00z run with the location of the path of the low through Indiana. At 72 hours it is farther east into southeast Michigan as opposed to South Central Michigan on the 00z run. So maybe a little east on this run.


Actually pretty similar to the 06z run in regards to the track.

12Z Euro coming in a tad weaker / NE track of the low which isn't good. We want East / SE not North or NE for the SLP track. A couple of inches of snow still doable with the arctic front. Then we dry slot and it's over for snowfall. Cold, windy, maybe some flurries maybe.

If I was in Michigan right now I would be pretty happy with the model runs today. But the NAM at this point seems to be our best bet. How accurate is the NAM?

Feel like the Euro has been really consistent this whole time and the GFS has been all over the place literally.
