Someone in Mapleton, IA, southeast of Sioux City, has reported 10".  Every winter a few locations in our region get a surprise storm like this.  I am only able to get 10" from the biggest storm once a decade.

season snowfall: 34.8"

'22-23: 30.2"      '21-22: 27.1"      '20-21: 52.5"      '19-20: 36.2"      '18-19: 50.2"      '17-18: 39.5"

Average snowfall: ~30"

^ yep- was the same here. It does change to good snow, but most of the good forcing / lift is done. OMA area did exceptionally well with this!!. Kudos to the weenies out W!! 

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.

The precip is changing to snow here now.  The flakes are tiny.

I was wrong.  It's actually still graupel, maybe on the snow side of graupel.  At this point I'm thinking 2" may be our max.  Heck, the HRRR is down to only 1.5" now.  Also, radar shows the good snow over central Iowa lifting northeast toward Waterloo (like the HRRR is now showing).  This is turning into a dud here.

Lol literally just woke up and have to work now so missed everything. No idea how much fell here, haven't read or looked at anything and don't have time to, just figure it was a good bit less than Omaha.

Bah.  We're almost two hours into this event and it's still not really snowing here.  It's still pretty graupel'y.  I spent days tracking this thing and this is what we get?  Ugh.

Total bust here. Some very light sleet and freezing rain. Dry slotted and barely any precip.  Low must  be further north  than progged just  36 hours ago?

Can easily see the mid-level low spinning over central Iowa... not a good track for either of us.

I even had a few drops of rain mixed at the beginning. Very fine flakes or whatever for a long time, but finally really snowed for maybe 10 minutes, now back to light snow.

I just measured 1.9".  If I spread some out on the pavement, it looks like a bunch of the little styrofoam pieces.

I wasn’t expecting much from this earlier on based on radar trends, but boy did this 1st wave develop into a nice intense band.  It almost felt like it was a thunder shower but with snow and wind!  Huge fat dendrites blowing sideways.  I’m sure those up in lake county can say the same.

The 8" band went all the way up to the Mason City area.  The models that showed this (NAM, in particular) nailed it.

Yes, it was really coming down nice up here. Visibility dropped to under half a mile for about 20 minutes.

I did not measure anything, but it has gotten pretty wet since that heavy band passed through.

So sad and disgusting. Local Mets here posted these messages.

I did an internship at a tv station years ago for a meteorologist and he played me some of the messages he had received from people so pissed off bc of a forecast that was wrong. 🙄

I ended with at only 1.1” or so, but around 0.40” liquid! Was kinda hard to push the ruler down through the solid snow/sleet mix. Also a very thin layer of ice on things.

My core samples from 1” melted to 0.30” but not sure on accuracy (wouldn’t be lower) from that as had quite a bit of sleet and a bit of zr at first. All reports around me are much lower than even my cores, but I’m sure it was at least 0.30”. Lots of erroneous reporting? My winter liquid equivalent precipitation is normally higher than even official reports and it’s been that way for many years.

Whats your Dec, Jan, Feb melted  precip totals?  At one point  we melted ice and snow.  And we also  had way higher precip totals than  the official  Ottumwa  numbers.  I really dont believe  the  monthly  and yearly precip amounts can be trusted  from what ive seen in my part of rural Iowa.
