January 10th-12th OV/MW/GL Winter Storm prospects

Are you using GFS? For DTW, 18z NAM gives 0.30" while 18z GFS gives less (idk how much yet, probably 0.20" or so).

If the ratios are what he says then my hunch is that is based off the GFS. I am wondering that as well?

Anyways it looks like the ensembles are going down in flames as they had ( still do i believe? ) remained constant with everything being further north. Pretty interesting stuff. Who knows the runs today could be a blip and the ensembles could end up right but it is hard to argue for further north when we have not seen it so far this winter. Anything is possible ofcourse.

Up here atleast this wont be anything like that. Not even close. :lol:

Unsure of what would be a good analog for this? :unsure:

IMO...this is the best analog qualitatively.

Yes...the upper-level mass fields are closed off but the low-level mass fields and moisture are very good. This "event" snow map needs to be fixed as the snow over OK and AR was from a lead system (actually much like what they are getting over the deep south right now). This is an excellent event analog though. So in the Midwest...focus on the snow that fell on the 29th and 30th in the next two links.

So a pretty unorganized snow field over MO, IL, and IN and I wouldn't be surprised if this is what will end up happening. There just is a lack of low-level organization and moisture IMO to get an organized area of >6" snowfall in the Midwest.

Well, our current snowcover after settling and sun is still about 2" (a spot here and there is 1" but overall definitely average of 2"), so any new snow would be welcomed since we arent exactly starting from scratch, but i still dont know...

18z GFS was way down with qpf at DTW of only 0.13", while as mentioned NAM stayed firm actually nudged up a bit to 0.30". It wasnt until 12z yesterday that the GFS/EURO caught onto to any real snow making it here though their ensembles held firm for days. Looking at the 18z gfs ens mean they have the 0.25"+ zone right at the state line so they did nudge down a bit, but the 0.10-0.25" goes all the way up into nearly the U.P. versus the OP making it to barely Flint. The GEM has been very consistent for many days as well, by far the first model to pick up on us getting any snow and everyone said its an outlier. So I still dont know what to think. I guess even if we get 1-2" it should be considered a win because until yesterday everyone wrote off any snow for us. But i still think a 2-5" event is a decent bet. Just dont know lol. And just after I had mentioned us being in a zone of pretty good agreement with the model qpf, this happens lol.

Yeah it is a very hard call out that way. I just know ( based on history) that you guys can usually score a few inches atleast ( especially you as you are further se of all in se MI ) with a surface low track in se/e.Ohio. Most of them have that atleast. The QPF will probably change right up till storm time which you probably know as well. Yes bullseye ( 4-8 ) looks to be IND/LAF/CMH-Ohio/along and near i70 but i can see a few inches sneaking into se MI. Thats me anyways.

Maybe a inch or so around these parts back to Chicago but thats about it. Ofcourse they could get some help via the lake in Chicago-ne.IL/n.IN. Tougher call with that.

I was using the mesoNAM Harry....sorry I got a little busy here.

Local TV guy here has 1-2"/2-3" for Tippecanoe Co. Seems reasonable to me. I really like 2-4" for LAF, with the heaviest stripe (4-7") from STL to IND to CMH to CLE. Not to completely ignore out west, where the western 1/2 of IA down to the KC area could pick up anywhere from 5-9".

I see nothing to change from a moderate event for the I-70 corridor in IND and W OH. I had 6-8" north of 70 and 4-6" south of 70. Specifics will still need to be fine tuned but by midday Wednesday I like 6" right across 70. .36 for DAY, feel that it starts out at 16 or 17 to 1 but a solid .25 falls at 20 to 1 with 850s -8 or lower and the last .10 below -12 C and we are getting in that 30 to 1 ratio range. I am not going higher than 6 for the area but a ribbon of 7 to 8 inches somewhere across Cent, E Cent IN, W and W Cent Oh into C Ohio could be witnessed.

sorry, know this isn't a regional comment but wow, that donut hole screw zone is frighteningly close to DC area again. Ouch if they get donut holed again during a storm that clobbbers philly north...lol

This makes me happy, the mass hysteria in NYC is going to be LOL worthy again too.

well i like the trend of a slightly stronger 5h low and 850 low as they move across IN and OH.....the precip details will take care of themselves. In an ideal world for mby, I'd like to see everything a smidge south, so hopefully a little more 5h digging in future runs.

btw i've always figured here in cmh that 3-5 is mod, 5+ is heavy. The reality is 5+ events are relatively rare here.
