Jan 14th-16th Upper MW/GL's Storm System

With the wind it is almost impossible to accurately measure the snow that has fallen, however it looks like I have picked up around 2 to 2.5 inches of snow in my backyard so far. 

Travel is not advised in the Omaha metro area and Eppley Airfield reported a 60 MPH wind gust around 7am. Fun morning around here weather-wise!

Surprisingly, I picked up 1.8" of snow.  Part of that total is a thick layer of slush.

It's unreal how many times Des Moines has been bulls-eyed this winter.

I'm not necessarily unhappy to miss out on more of this slop.  Even the one inch on the pavement is very heavy and there is an ice layer at the bottom which makes it difficult to get any traction while shoveling.

Another wet snow here in KC. Treated roads are just wet and most parking lots with salt down are wet to a bit of slush. Radar trends are not that great to the north of the city, hopeful radar can fill in here soon. We have just under an inch of accumulation but it is melting now on all paved surfaces.  So, we're not maximizing the snow accumulation due to temps around 30 degrees. 

These types of snow have been very common here in KC the last two years, I can't remember the last time we have had powder and snowfalls with temps in the teens and low 20's. Very warm winter last year and this one has started very very warm.

Outside of that, it is a wintry day here in KC.

I may have up to an inch of wet snow, but pretty much same as @MIKEKC is reporting. Temp here 31 and my side street is slushy. Not really any blowing or drifting to speak of. What's interesting is there has been mostly light winds since the snow started after it was howling yesterday and last night. Just the standard 1" wet snowfall...meh 😐

Not gonna be upset with Des Moines being bullseyed this year. Much like us, they’ve had a tough go at it the past several years. 

Des Moines recently went years without a 6" storm.

These snow squalls are legit.  I was just underneath one for about 10 min that was puking fatties from the sky.  It's to warm for the snow to stick but looked nice while it lasted.  The clouds have a stadium look to them which illustrate the instability in the air.

The most creative way yet to dance around SWMI and deliver snow to NMI, Iowa, Kentucky, etc.

You know, all the places that actually are getting what snow there is in this mild pattern.

Must say, this is a good year to be a snow enthusiast in Tennessee.

Let's see if the 2nd half of this storm can at least produce enough snow to cover up the grass.  Currently getting some light snow with a temp of 31F.  Got a coating so far and the models suggest parts of N IL could end up getting up to 3" by Mon..that includes a lot of us over the Lower Lakes.

LOT mentioned some of the more intense squalls in IN produced lightning strikes...

The snow showers have certainly performed as expected today, with
intense cores able to produce sharp visibility reductions and
quick localized accumulations up to an inch. Earlier there was
even a cloud to ground lightning strike down in Benton County
Indiana.

@jaster220, UKIE likes your area...hopefully this system can finish off with some decent LES as the parameters appear to be decent esp with the upper level energy swinging through Sun/Mon.

I'm seeing a good signal for some pretty good LES bands coming off of LM later tonight through Monday...you could get lucky and pick up a few inches...0.30qpf can easily fluff up to 3-4" in spots...

Had a surprising last band of snow around 8:00 pm last night(snowed really good) after the main part of the storm had been done for 5 hours or so. Coated everything and topped off the day. I ended up with 2.3 inches at my house in KC north. It was mainly a grass snow storm. I would say it snowed 3.5 inches worth if it was colder. Nonetheless, it's a beautiful winter's morning. 

Back to model tracking. 

Go Chiefs!

Congrats you did much better with this storm than me, I finished up a little under an inch.  Hope the Chiefs get it done tomorrow.

Final post in this thread?

came home to a ground dusting.

Per my office, while tomorrow looks promising warm surface conditions mitigate any headlines. We shall see but can't argue the history to this point. Only one legit cold snow and legit WWA back on 12/29.

.UPDATE...
Issued at 756 PM EST Sat Jan 16 2021

I have increased the POP and QPF for this evening as we have a
decent shortwave and surface trough moving through the CWA this
evening. There has been a significant increase in snow across the
western sections of the CWA. This is related to the back edge of
the upper jet around the departing closed upper low, which and
become a Nor-Easter over New England. This shear zone has created
an area of surface convergence, which at 7 pm was maximized near
US-131. Our VAD wind profile shows returns to 11,000 ft and
between 1000 ft and 2000 ft the wind is turning cyclonicly from
the southwest to the west, showing the trough moving through.

All of this tells me (and the hi-res models agree) the snow will
continue through around 9 pm then diminish. Since air
temperatures are just above freezing the snow should not cause to
many travel issue. Snowfall amounts this evening should not be
more than an inch.

Meanwhile the developing closed upper low that is to our west at 7
pm can be seen as enhanced cold cloud tops over MN. This system
develops rapidly in the next 24 hours and becomes a closed upper
low that tracks east, south of I-80 Sunday. Curiously the upper
ridge that develops in front of it should help diminish our
current snowfall event by late this evening as the upper ridge
moves in and causes subsidence at mid-levels.

Toward morning though we get into good upper divergence as the
developing upper low moves into our southern sections. This will
significantly deepen the clouds to well over 25,000 ft. The 18z
NAMNEST shows good lift and convergence along I-94 south to I-80
most of the daylight hours of Sunday. So I could see better
snowfall in that area. Still surface temperatures will be just
above freezing so it should not result in anything needing a
headline.

Need like 2F freakin colder to make this almost a certain plowable event. Such a dismal "winter" to date.

SR models hinting at a nice pivot point for here and even looking like a possible period of weenie rippage. Too bad I have a grid high in the mid-30s and worst possible afternoon timing. Funny how it's only a few degrees warmer in Florida attm than here in Michigan. Yeah, that happens every year. #stupid
