12/10-12/12 Plains/Midwest/Lakes Weekend Snowstorm

[CentralNebWeather]

It is stopped at hour 25.

[Tom]

2.25" down IMBY...snow has let up for now...pixie dust...

[indianajohn]

Nam really backed off???? 

[Tom]

I took a stroll around the neighborhood and soaked it all in.  Very peaceful with all the lights and a fresh blanket of snow.

[shakjen]

Had a good half hour of snow again but it has stopped again. Filling in again back in Iowa but may take while to get here.

[East Dubzz]

Not sure what to expect here. Models look terrible. But NWS just upped my total in their graphic. And the radar looks like it may be filling in. Just no idea, I could see waking up with anything from an additional trace to 4".

[gosaints]

Pretty good rippage under weenie band

[Money]

That band looks nice

 

Milwaukee expects band to continue moving east and more bigger redevelopment later tonight

Should probably be under a warning here. warnings in iowa counties could underperform here

[Tom]

LOT's discussion regarding radar trends in E IA and expected trends overnight:

 

 

 

Initial region of warm-advection forced light snow overspread the
region late this afternoon as anticipated, with heavier (mainly
moderate) snowfall within a region of frontogenetically-forced
northwest-southeast bands. Recent radar trends show this banding
has weakened and lifted northeast across southeast WI, Lake
Michigan and northern IN at this time. However, 00Z DVN sounding
depicts a fairly deeply saturated column with nice veering wind
profile signature associated with strong warm-advection. Within
this region of persistent upglide, latest high-res guidance
continues to support regeneration of transient f-gen banding which
should continue to result in periods of moderate or greater
intensity snowfall. While we`re currently in a lull in radar
returns especially across the western parts of the cwa, stronger
returns are blossoming across portions of eastern IA, and would
expect an uptick in coverage and intensity later this
evening/overnight as forcing and moisture advection persist. With
the first band working to moisten initially dry low-levels, will
likely see additional bands more efficient in lowering vis and
producing heavier snow, and latest RAP soundings suggest a decent
period of deeper dendritic growth after 05-06Z.

Initial bands of snow have produced 2+" of new snow in many spots
across the warning area, which is in line with going forecast
amounts through 06Z. Thus not inclined to make any big changes at
this time, with expected redevelopment and increase in snow
coverage and intensity later tonight.

How much do you guys in MN/WI have so far???

[gosaints]

How much do you guys in MN/WI have so far???

Ill go measure. I am under weenie band about 15 miles north of I90 in winona county

Nice west/east orientation of those heavier returns. Looks like you should do pretty good as well as S/C WI.

[westMJim]

We had light to at times moderate snow here all day long. Now have a total of 8.75" on the ground. The snow here is very fluffy and thus very easy to move. Still getting light snow but the flack size is now much smaller.

[BrianJK]

I dunno Tom, sure looks like we're going to get missed by the remainder of this first wave. Seems too far north. S WI looks to do well.

[gosaints]

Closing in on 4 inches

[Money]

Closing in on 4 inches

How much were you guys supposed to get?

[Tom]

[gosaints]

Wow, nice We have 2-3" locally.

Ya should do pretty good.  Wont stay under the best returns to much longer but should be in and out of decent stuff through the night.  Shows how fickle WAA frontal bands can be. NWS la crosse was banking on it setting up in northern Iowa

[Money]

WI/MN looks pretty good imo. Nice wide band slowly moving east. N. IL should do decent also if the stuff in Iowa continues to strengthen 

[Tom]

I dunno Tom, sure looks like we're going to get missed by the remainder of this first wave. Seems too far north. S WI looks to do well.

2-3" locally thus far ain't bad, if we can get a few more by morning I'll be happy before it ramps up later tomorrow.

Had LES until 5 pm, winds went calm, by 10 pm the system snow had moved in so a whopping 5 hr break in flakes flying. That's NMI wx right. there! ☺

[gosaints]

back to pixie dust. Pouring pixies though

[Madtown]

Right around 3-4 here

[Tom]

Using Wunderground, you can relay the fronts tab and radar simultaneously and its neat seeing the snow start to fill in near IA just N/NE of the stationary boundary which cuts through DSM.

[Tom]

MKE area getting some good rippage...S WI is looking good right now for at least a few more hours...

[jaster220]

GRR update worried this could over-perform and require an upgrade. Speechless. Are they totally out to lunch that office?

[Tom]

Looks like WSW's were extended up towards S MN (Gosaints area) and LaCrosse area...

[Tom]

Finally measurement of the night and I have 2.75"...radar trends don't look to enthusiastic, we'll see how it looks when I get up in the morning...adios!

[midwest buildit]

Where's my snow. About 3" so far. Hasn't really snowed since 8pm.

[Madtown]

I believe a forecast fail?

[midwest buildit]

The updated warning at 340 is still calling for 7-12 total.

[gosaints]

Solid 8 inches

[St Paul Storm]

Still snowing here. I haven't gone outside yet but my guess is about 4" so far with some heavier returns out west to push through yet. Should be close to 6" by the time it's done.

 

Gonna be some disappointed people in Chicago when they wake up based on the reports. Doesn't look like they got close to what was forecasted....so far.

[St Paul Storm]

Nice! MPX in their morning disco talked about the weenie band down there that just sat for a few hours. They estimated 10" in spots.

Only sitting at about 3-4" hasn't snowed much at all since 8pm. Im just west of chicago.

Wow. Wasn't 8"+ forecasted for north of I-88? Still time today to gain on those totals. I used to live in Naperville. The company I work for is based in Lisle.

[FV-Mike]

Forecast still going with another 4-8 for majority of the Chicago metro today

[midwest buildit]

I live in lisle and plow in lisle and naperville. North of 80 was 8-12 not all by morning though.

[GDR]

Sure does look like a lot of dry slots on the radar
