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!

I figured that wasn’t accurate 

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

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

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

‘20 - ‘21 season snowfall = 38.5”

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.

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.

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

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.

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.

Yellow overhead now, but looking out the window it doesn’t appear heavier than earlier judging by visibility Etc.
