6z GFS goes further east, as did the 6z NAM.

I don't have access to the full suite of GEFS, but the 11 members you see on the PSU site are pretty much in lock step with their OP model.

Should be interesting. I'd probably stay away from the EURO solution until there's more intra/inter model run consistency.

Granted the euro has been much more jumpy on this then the gfs,  but I can't think of a time where the gfs pulled the euro into its solution inside 96 hrs, especially with this type of storm.   That and the ukmet jumping to the western solution makes it very hard to ignore, and probably correct.

Only good news is I just checked and the euro has pulled so far west we are now out of the freezing rain threat too.

The 6z gefs mean precip shield is much further west than the op. At this point I'd say everything is in play

EURO still looks further west than the UKIE or GEM. It's definitely possible given the strength of the s/w in the base of the trough and the strengthening baroclinic zone that a storm could rapidly deepen and curl N/NNE. But I'd play the compromise game attm given the kicker on its heels (that won't even be sampled fully til about 66 hours).

The only puzzle piece that didn't fit into the usual road to disappointment, was the nam jumping in the gfs camp full throttle.   I know the nam sucks but usually in this situation you'd expect it to hump the euro's western solution hardcore.

This is what surprised me as well. Then again, the storm hasn't really entered the NAM's wheelhouse time frame either.

I think we are still in the game ... barely.

Board is alive and chirping at this hour. Refreshing to see a good ole fashioned '78 blizzard redux can draw out the folks....still. Apologies if there wasn't enough meteorological value in this post for some.

Might be about 50 millibars too high for that comparison ;)...  But I agree, at least we had something to follow.  Although I kind of hope I can tuck this one into the failure camp (if that's where its headed), sooner rather than later, with some better concensus today.

Granted there is the possibility of a coastal transfer depending on how far S or SE the LP tracks. The vort timing is key and whether it interacts with the kicker, as spoken earlier, which wont be till within 60 hours. The transfer may play a role in how strong the initial low is. I'd expect a somewhat clearer solution/consensus by tomorrow 12z.

Looking at the eps, the slp placement mean at hr102 is over central WV, yet as mentioned earlier, the snowfall mean matches the OP almost perfectly.  Seems odd, but maybe that's an indication that the further nw solutions are also the wettest, or at least the snowiest, solutions.

I was wondering that myself.  Looking at the "low locations" on the Euro ensemble, they are almost all west of the mean SLP area. :huh: The biggest cluster of lows is basically right up the I-71 corridor as it comes through Cincy/CMH.  My cynical forecast called for that 2 days ago so I'll roll with that :lol:

Great to see this board active with a potential major storm to track (finally) Woke up with 3 new pages to read! 

Frontogenesis band is the main threat up here, and it is going to be extremely narrow so I am a touch worried that models have me in the bullseye 48 hours out. The local forecast office placed the whole area under a WSW as a precaution but my guess is it gets trimmed to a few counties wide in a SSW-NNE orientation tomorrow.  Whoever is under that main frontogenesis band in Minnesota will be in for a solid 6 inches and then back into the freezer!

Your event up there is tied to this first wave coming onshore. The event further east and south will be tied to a different secondary wave rounding the base of the trough late this week
