although this is a good sign from GRR AFD:

.UPDATE...
Issued at 1245 PM EST Tue Dec 29 2020

slightly sooner arrival of the snow is expected this evening so
the headline start A time was moved up.

The winter weather advisory was expanded as well.

Impacts are expected for the Wednesday morning commute for the
remainder of the CWA. As a result we will expand the headline to
include places like Lansing and Battle Creek. Mainly snow is
expected to the north of a Holland to Grand Rapids to Alma line
where 4 to 6 inches looks likely. Further south the snow arrives
tonight with a couple inches possible. A period of freezing rain
or sleet looks likely before temperatures rise above freezing
late.

Nice!

Picked up 2.1" in last hour downtown Des Moines.  And this wasn't even with the heaviest returns which are just about to push in next 30 to 90 minutes

Also, SWMI should do fairly decent w a 3-5" snowfall. Now that snow is arriving earlier, amts could be higher towards the 5" range.

This is crazy. It's been YEARS since I was able to use my snowmobile in December. I'm right in the bullseye in SE Wisconsin. Are we actually going to have a Winter this year?

Wishing I still had my old Polaris 500 SKS(700 hood, wish it had the 700 engine)...  This is perfect snow for snowmobiling!!

[Sparky 1677]

Suddenly it’s really snowing!

 

A few minutes later the visibility is down to around 1/8 mile.

[bud2380 3462]

Radar is extremely impressive. Winds are fairly brisk so until the snow gets more wet it will be  a little tough to measure 

[Hawkeye 4420]

Solid light snow here.

I didn’t either as it’s totally surrounded by snow.

Right on. Red returns south of Des Moines! Wondering if some of that is sleet or very heavy snow!

[Hawkeye 4420]

Good area of mix south of Des Moines, going to lift northeast.  We will need a couple hours of 2"/hr to get the bigger totals.

The latest HRRR is down to 8", which I would certainly still be happy with.

[Stormhunter87 963]

Starting the wrap up here but I'm actually impressed. May have made it past 8 inches.

[Sparky 1677]

Well I need to go out a bit and see if my snow boards are enough behind the windbreak and enjoy the snow!

There is a serious band pushing 50dbz just SW of Pella that is probably doing 3-4"/hr, maybe more. No bright banding either.

 

As for our area. It's coming down at a decent clip, but flake size is rather unimpressive currently. It's not bad by any means, just unimpressive. 

[Sparky 1677]

It’s puking snow! A strong 1” already,

Have a friend flying from O'hare to DSM today at 2:30. Flight is still on. I told him this morning there was no way it would be getting out

[dubuque473 272]

Ready to go here. Thinking within the next 2 hours.

This snow is in a rush to arrive here in SEMI....not wasting time at all.

Column just starting to saturate here. Nice 2-5” refresher. Glad to see the high rates in IA! Good luck all!

And we have snow flakes..

[james1976 3934]

Snowing hard!

[james1976 3934]

So........its done snowing west of Ft Dodge already?

[bud2380 3462]

Even though flake size is small to medium, I picked up about an inch already in about an hour. 

[hlcater 1321]

Just now, james1976 said:

It's not. Some funky beam height shenanigans going on. Stations still reporting snow with visibilities ranging from 0.5-1.5mi. Though the DGZ out there isnt especially saturated so I cant imagine the snow is particularly efficient at accumulating.

[Hawkeye 4420]

0.8" at 2pm.

[Hawkeye 4420]

Bright yellow on radar about to move into Sparky's area.

[Hawkeye 4420]

Last night's 3k NAM had far sw Iowa getting no snow at all... all mix.

7" of snow fell there this morning.

It's safe to say the NAM blew this one.

[james1976 3934]

Pounding here at work in Janesville. Leaving early to head home. Hope the rates are awesome after I get home.

That didn’t take long. Ripping pretty good, surfaces are already covered and the wind picked up. 

[OmahaSnowFan 1241]

Measured 5.5" and it looks like that will be the final total. Nice snowfall, but definitely disappointing considering where this all started.

[Sparky 1677]

I’m already over 2.5” and it’s still puking especially just now. Also a few lightning strikes a minute or two ago in sw. Iowa.

[East Dubzz 1312]

After that initial burst of snow, it hasn’t snowed here for a bit now. Just waiting for the main event to start up here.
