Is that the second wave?

Yes

Models have been showing some relative consistency with it lately, so hopefully something happens somewhere and it isn't one of those mirages.  

A surface low that makes it to Alabama usually isn't good for areas where I am and farther west, unless the wave quickly takes on a negative tilt.  Therefore, would currently favor areas to my east having a better shot at something significant, but still tantalizing enough to keep me watching lol

I'm happy to see that the UP does a lot better over the entire run for preserving and adding to snow depths.

I have a good foot and a half of snow depth here with several more inches coming tonight. I would be shocked if I lost it all after this week...but lake effect goes fast...but it is a couple feet of dense lake effect compacted. It was HEAVY when I shoveled my roof off last week. So, we shall see....

GFS does look cooler in the long range and doesn't take me above 40 at all. At the very end, though, it shows 3 INCHES of rain with temps in the mid 30s...lol. Yes, I know that will change... hopefully? :P

Buffaloweather wants to lock in the GFS for a synoptic dump.

Actually, the GEFS and EPS ensemble means are in amazing agreement with the low placement for six days out.

I'm highly skeptical of that low placement. 20 years living on the east coast, I very seldom recall seeing a low rising along the ridge of the Apps actually verifying. Gives me hope that the secondary will shift west with time.

That was a pretty common track during the 1990s.

It will end up over Toledo.

I could see that.  Then again trends west and stronger have been a rarity in the modelling.   Could also see this morph into multi-piece waves riding a front further east.

On top of all that we have the first low cutting up into the mw on Thursday.  I'm sure how that plays out will have a big effect too.   IOW,  maybe we'll know by the end of the week the what and ifs.

Still a little nervous about letting it get to the lat/lon of Alabama.  That could work for us but there's no margin for error with the handling of the trough at that point... gotta quickly go negative tilt or else it's easy for it to escape east of where we'd like.

That Euro run is about as far West as you will see this, the 500 pattern with neutral tilt at the river would suggest east, this basically went north northeast from MS which is a rare storm trajectory, I would have expected something more northeasterly.

Yep see above for similar commentary. Euro still is a bit notorious for wrapping up systems too strongly in this forecast range as well.
