February 5th-6th Midwest Snow Storm

[St Paul Storm]

I-80 jack zone in IL. That E-W band is going to move continuously over the same area.

[VMB443]

Started here. As has been mentioned by others, small flakes but coming down fast.

[jaster220]

Apparently GRR likes that banding, and raises us another notch along 94 corridor..

 

.SHORT TERM...(This evening through Wednesday night)
Issued at 330 PM EST Mon Feb 5 2018

Will make a couple more tweaks to the current headlines as accums
continue to trend a bit higher. Will add Ingham and Jackson
Counties to the advisory. Also will end the advisory at 10Z as this
is a quick hitter and the snow should be over prior to the morning
commute.

Coupled upper jet will be squarely over the region later this
evening, bringing the steady snow that was over IA and Northern IL
into Southern Lower. Snow accums in IA have been in the 4-5 inch
range, and since this will be lake enhanced expect at least that
amount to occur here.

The lift from the upper jet will be strongest over the area south of
I-96, so it makes since to include Ingham and Jackson. Areas west
of U.S. 131 will also see decent snows largely due to the lake
effect. Mean flow early this evening will be about 250, but by late
evening it will pivot to 280-290. So this sprays the entire lake
shore as the moisture depth is healthy. Highest totals of 4-6
inches are expected south and west of Hart to Freemont to Battle
Creek. The advisory buffers this line to the north and east, for a 2-
4 inch accums. The upper jet lifts away quickly, so have the
advisory only running until 10Z. The message will be the snow will
be over by the morning commute, but untreated roads will still be
slick.

[Hawkeye]

The yellow heavy bands on radar continue to bubble up in between Muscatine and Burlington.  It's too bad spotters are lacking in that area.

[jaster220]

I think every Mid to Short Range model showed the dynamics of this wave crapping out as it headed to SMI, yet per the updated AFD, it appears to be holding onto it's moxy much better, thus the WWA's been bumped further eastward twice now. I think this bodes well for the other waves/systems coming our way later..

[Hawkeye]

Just gorgeous here now, the best snow of the event... large flakes pouring down.

[shakjen]

I-80 jack zone in IL. That E-W band is going to move continuously over the same area.

Actually the heaviest is just south of I-80. I live 200 yards south of 80 and had friends  a few miles south of here saying it is really snowing hard. Just light snow here.

[Grizzcoat]

6" MBY-- 30 SM NNW of KDSM--- it's awesome. Which it should be. Biggest snow in 3 years which is sad and good at the same time.

Yeah good call. It’s south for sure. The Peoria area getting raked it looks like.

[Minny_Weather]

OAX isn't biting on a WWA. It's not needed now imo. If it's warranted they can just issue one in the morning tomorrow.

[Hawkeye]

3.2 inches here now, 1.3 in last hour.... real fluffy dendrites.

 

Flakes just went back to small as the brighter returns have moved east.... should be able to pass 4".

[hlcater]

While Hawkeye has been getting good flake size, my flakes are small at best although rates are intense. No idea how much I have, but it's probably about 3.5." We'll see 4", but 5 may be a stretch and certainly not 6, which was modeled. Meanwhile I would not be surprised to see 8" reports out of SE IA when all is said and done. 

[bud2380]

Sometimes you have to wonder what the NWS is looking at.  This is basically completely wrong, the entire statement.  

 

 

As
of 2 PM, the main band of moderate to heavy snow is located between
highway 30 and just south of Interstate 80. Thus, far a bit
farther north than much of last night`s guidance suggested.

[Hawkeye]

I wish some farmer south of Muscatine would send in a report.  I got heavy snow under bright green radar returns.  It has to be insane under the bright yellow/orange down there.

 

We are getting moderate pixie dust as the storm begins to wind down.  We should get another hour of this followed by lighter snow for an hour.

[james1976]

Exactly 3" here. Sun is coming out now.

[bud2380]

Up to 3.8".  The wind has completely stopped here as well.  We should get over 4" maybe up to 4.5".  I'm not going to complain, that's right in the 4-6" range the NWS called for.  I was hopeful for the higher totals shown on the HRRR and occasionally other models as well, but we just missed out here.  

[Minny_Weather]

North winds have picked up and snow is blowing now. Actually looks cool with the sun out.

[shakjen]

Yeah good call. It’s south for sure. The Peoria area getting raked it looks like.

Talked to a friend in Galesburg, and its coming down really hard there. Look like the hardest is from Galesburg over to Pontiac

[Hawkeye]

3.9" here

[Minny_Weather]

Point grid has 1-2" for here tomorrow. Seems about right.

[ToastedRavs]

Snow ended just now SW of DSM. Got 5.4", not too shabby

[bud2380]

4.4” still snowing a bit. We might squeak out that final tenth

[centralweather44]

Did you happen to see what offical amounts were reported for today in Lincoln?

[Hawkeye]

8-8.5" in southeast Iowa where the heavy band parked, and it's still snowing heavily there.

[bud2380]

A couple 8+” reports in SE Iowa. I knew they would come in high down there.

[Minny_Weather]

Did you happen to see what offical amounts were reported for today in Lincoln?

None officially reported yet. Inch in Waverly. I measured 0.8" on the Southeast side.

Where's GDR at? He's somewhere down there right?

We got around 0.8" near Capital Beach in Lincoln too. Was fun to watch I suppose lol made a mess on the roads though and it's like the awkward amount where you can't really plow it so i'll pass on anything less than 1".  

[Niko]

Snow knocking on my doorstep.

[hlcater]

Measured 4.6” although it was kind of a let down. Makes sense I’d have a hair more than to the south as it was pretty steady here all day without many lulls.

I just drove to class. Arterials were (mostly) plowed. Of course, it was a half a** job with the type of plows that only do half of a lane.

[Minny_Weather]

LNK officially recorded an inch! Yay! I can add another date to my signature when I get home!

[bud2380]

There’s a 5.4” report from Iowa City. I finished with 4.6”. I did get 5” in some spots but the place I was measuring all day had 4.6”

[Hawkeye]

Here are my totals:

 

Snow: 4.4 inches

Liquid: 0.31"

 

We received qpf spot on with the general model consensus.  A couple models were under 0.30 and a couple over.  The ratio was only 14 to 1, so that's where we came up short.

LNK officially recorded an inch! Yay! I can add another date to my signature when I get home!

We should be able to limp our way to double digits for the season tomorrow.

[Madtown]

2" here

[bud2380]

4.8” report from Solon and 6” in Iowa City

[GDR]

A tad over 7 here. Came down hard for a few hrs. Biggest snow here in a few years.

[St Paul Storm]

Chitown bust today? Peeps in Naperville saying they only have about 2-2.5” down and things wrapping up quickly.

[earthandturf]

Thought I'd be leaving to plow around 8:00, but the back edge is still at Rockford and there appears to be a couple bands of heavier snow blossoming behind it. Hmmm.

[Hawkeye]

South of Muscatine, IA and across the border into Illinois, some totals of 9.0-10.5 are being reported.  That's most impressive.
