that's a weenie band - but a good start.   Still think this shifts E and slightly S. Good luck to ALL!!!  The reason the Twin Cities has not done anything --means something is up. MPX is ansy between WWA and WSW no doubt.  My .02-- wash. Not a big deal as they say in AFD.

The two loudest sounds known to man: a gun that goes bang when it is supposed to go click and a gun that goes click when it is supposed to go bang.

Winter Weather Advisory posted for my county. NWS calling for 2-4 inches. Looks like most of the 06z suite (NAM, NBM, RGEM, HRDPS, and Euro) either moved the band slightly NNW and/or upped totals again.

Good luck bud!  Hope you finally get to see it snow at a good clip and whiten up the brown ground and make it feel like Winter.

And then we have the Canadian model, which is a full fledged winter storm warning for a huge swath.  Quite the model discrepancy at this point for so close to the system.  They all agree on the general idea at least, but strength and placement (as always) differ significantly.

Though it can't compare to what looks to transpire farther south, there is a narrow tongue of SBCAPE that develops northward toward southern Lake Michigan late Tuesday.  I don't know whether it will be enough to result in some isolated severe weather, but it's one of those 'don't be surprised if it happens' kind of things.

Trend gif of the past few NAM runs. Latest run made a decent jog SSE with the heaviest amounts. Also upped amounts within the band of the band... Now showing almost a foot in S Central MN.

Not feeling too confident for tomorrow as I'm thinking I might be just a bit too far NW but even 1-2 inches would be nice and would easily be the most we've gotten so far this season.

Kind of upped me a little.  We'll see.  Was just put in a Winter Weather Advisory for freezing drizzle first then potentially 1-2" with wind.  I'd guess closer to 1/2-1".  Not expecting much, so I hope to be pleasantly surprised.

RAP is taking a page out of the RGEM playbook and just keeps up up upping totals.

I don't follow this model too much so I'm not sure how accurate it is but it definitely seems to be smoking too much of that good good, if you know what I mean... 😉

It’s good at predicting mesoscale banding but don’t get sucked into the higher totals so much.  I use it a guidance to show where the heaviest band will likely lay out.

Something not touched on as much so far - the nice little shot of cold air accompanying this system. Big 24hr temperature changes for many folks.

I live for 24hr temp drops! 

Seriously tho, nice to see a classic late autumn CF bringin a punch! Should be a blast next time around. 

So, where are all the NEB Peeps that are usually on here when something worth following is finally in their region??

The HRRR is explicitly showing some enhanced gusts with the squall line that gets going along the front

This has definitely trended back north.  A day ago a few models were mostly missing MSP to the south.

 

season snowfall: 34.8"

Looks like they fall apart for SEMI, though your map doesn't show fully.

Yeah it does start weakening then.

DTX pretty much "meh" on even advisory level winds due to a couple factors mitigating mixing potential. That's fine, we got the windstorm a month early with the mid-October spinner. Looks like best chances for higher wind gusts will be with the two shower set-ups:

Forecast
soundings and hires data supports some beefy low topped convective
shower potential between 09-12Z along the front. The potential will
exist for briefly heavy rainfall rates both Tue evening and early
Wed morning, but a strong consensus exist for 0.25 to 0.33 of an inch.

Looks like MSP has been upgraded to a WSW. "Heavy snow expected. Total snow accumulations of 4 to 7 inches, with locally higher amounts possible." 

Sounds like @james1976might score the jackpot!

Yep, takes on a nice angle/path orientation for MSP:

Yeah I'd agree on the synoptic winds mostly staying under advisory criteria.  I think the IL/IN area may flirt with it tomorrow with some gusts around 45 mph, but it's borderline and the duration of that looks somewhat limited and none of the offices have issued an advisory.

Yup! Was just coming in here to mention this. Surprised they upgraded this soon but definitely stoked. And it's a daytime event!

What looked like a real blasting in of BN temps has become nothing more than a brief interlude, and a wash-rinse-repeat pattern which we are on the boring side of.

This storm fits perfectly well with the storm back on Oct. 11th when we had a cold front move through. My area got missed out but Lincoln, Omaha, KC and areas east was hit by severe weather. That would put this years cycle around 49 days. Currently 23 degrees and had a freezing rain mix earlier this morning but that has since changed over to snow. The snow is blowing around pretty good and has a nice winter feel out there!

We have a 10:00 AM late start this morning.  Very slick in town when I came to school at 9:15 AM with snow blowing sideways, but no visibility issues.  We aren't sending out busses today.  Going to be many absences I'd assume.

Very slick around here too. We started with a late start but we have since called off school. A lot of the area schools around ended up closing. We haven't received a ton of precip but man it looks like winter out there at least! We have a decent band of snow that will be moving through the area that might drop an inch of snow if we are lucky.
