@Jackstraw Euro is doin' its thing to us.

A bit strange to see such a dramatic reversal - it's on an island at this point. Even the ensemble isn't quite so drastic with the cut off. 

If some of the hi res guidance suggested something like this I would start getting concerned, but after seeing the 12z GFS/HRRR, as well as the 15z RAP, I don't think this run was the start of an overall trend. Crossing fingers

I worry about mixing too. Winds will have a southerly component here for the whole event and the low tracks to our NW. Even in January, that gives a rainer almost every time. We should at least get a good hit near the start though. 

Yeah the early morning through mid to possibly late afternoon look good here. Probably several hours of solid rates. But I would be shocked with a low track that north if we dont mix or switchover at some point. But good thing is here looks to happen towards end of the event when most of our accumulation is done already. This system doesn't have much of a deformation zone.

Crossing my fingers too. I saw your call and if it is onto something, you might have to bring your totals down a little, especially to the south and I would that for you (and me lol). But at least you have warned the public about possible last minute changes since we are riding the edge. So far IWX and you are in pretty good agreement though.

For old times sake, SREF plume has me at 9.5” with a number of higher members and nothing below 7”. Locked in.

Must be nice. Lol. Y'all really get spoiled up there. Can't tell you last time we got double digits snow here.

Yeah, I noticed IWX has been pretty hesitant to use their NDFD output until recently! 

And wouldn't you know it, 12 ECMWF came in wetter/snowier, and in better alignment with the rest. Right now, I'm going to wait for the 18z NAM/HRRR to come in before making drastic changes, but my team is struggling with whether we want to keep things the same or up the totals since the consensus has been overwhelmingly snowy for most. My argument against is compaction, which could give off the impression we were dead wrong lol! 

Also, I'll be curious to know how well the NBM does when all is said and done. It has hardly budged over the past 48 hours

MLI will exceed its 2024-25 total in 2025-26 before December.

Thinking 4-6" here. Hoping the dryslot/potential end as rain in sunday morning isn't too bad. 

Yep, and ironically it'll be the very first measurable snowfall of 25-26 there lol.  Have had 0.3" here.

[King James]

Wild how nonchalantly we stumbled into maps like this. Like Alek mentioned, the decent antecedent conditions for once is cool and something I'd willingly accept in lieu of better ratios later on.

Every single member on the forum has been sleeping on this one

I'm glad to hear that the Euro decided to play ball. I wasn't aware of that concerning the NBM.

That 1 foot swath is about identical to the derecho 2020 swath lol.

Kinda annoying were starting the yr off with similar outcome around here lately with totals dissipating as the storm rolls east. Enjoy ia,il,in,west mich folks.

Gonna be interesting to see the variations in storm totals from west to east in the Detroit Metro.

Trends aren't bad at all.

Still looks like a solid snowfall. Very solid November.

I don't think the negative lake influence will be as prevalence as some models show.

[sbnwx85]

WSW up. I never dreamed November would produce another big dog this year after the 10" lake-effect event three weeks ago, but here it is. 

Some areas to my immediate northeast will have 18" on the ground thanks to last night's lake event.

DTX is gonna have to go from no headlines to warnings at this point

Nah, advisory.

Gonna be funny with SE Michigan with an advisory and Toledo under a Winter Storm Warning,

Yeah, I normally don't disagree with DTX, but with the holiday travel and the face that the western part of their CWA is absolutely going to be warning criteria, I don't get the reluctance. I would do WSW for the entire CWA, it's borderline but the travel would be the tipping point to a warning

If IND can pull their WSW all the way south to Indy, DTX can cover their CWA with a warning, too.

Must be contagious. First it was GRR for several years, now DTX too. 
 

I agree with you 100%. Second busiest holiday travel day in conjunction with 5-8” of snow and 30+ mph winds… just issue the warning. For many it’s the difference between waiting a day or two and just hunkering down vs. in the ditch with a wrecked vehicle or worse. Who cares if the amount of snow doesn’t specifically meet “warning” criteria, it’s irrelevant when it comes to life & safety IMO.
