You may have mentioned it before but do you know when the last double digit snowfall for Lincoln was? Best of Luck

Thanks. Feb 4 2012 (mild winter) recieved 11.1". I didn't live here then, but it seems like temps were marginal and it melted fairly quickly.ย

.SHORT TERM...(Today and Tonight)
Issued at 446 AM EST Mon Jan 25 2021

The Winter Weather Advisory looks on track, with the main change
being slightly lowered snow totals for all but the far northwestern
forecast area in favor of...you guessed it...our favorite weather
type this year: FREEZING DRIZZLE! This event is a great lesson in
why we don`t encourage the sharing of snowfall maps more than a few
days out: things can change quite a bit.

Snow is a little less heavy than it was 30 mins-1 hr ago but still coming down good. Looks like that modeled rippage band might be setting up for the OMA/LNK metros, so it'll likely get more insane soon.ย

GRR updates. Expansion north and now going 3-6+ (not bad)

ย 

.UPDATE...
Issued at 1036 AM EST Mon Jan 25 2021

We are expanding the Winter Weather Advisory this morning for the
system tonight into Tuesday up to a line from Muskegon to Mt.
Pleasant.

There is a good consensus of models and ensembles, including some new
12z data just coming in, to support the expansion to the north a
bit. Overall, the system is delayed a tad in getting started this
evening. This is fairly typical, and is likely due to drier air
that erodes the leading edge of the precipitation initially.

Once the stronger forcing arrives however and the low level dry
air is overcome, we will see it snow pretty good. These better
snows will be centered just before and right through the morning
rush hour on Tuesday morning.

The consensus is that much of the area between I-96 and I-94 will
be the axis of the heaviest snowfall, where 3-6 inches looks
likely. This will taper off a little to the northern edge of the
new advisory area to roughly 2-4 inches, and then tapering off
quickly north of that area. Due to the nature of the fgen bands
coming through, we could see some locally higher amounts where
they may sit a little longer.

We do think that there will be some blowing snow around as
temperatures will be below freezing, and wind gusts of 20-30 mph
will be likely.

Every run of the HRRR gets worse and worse for eastern Iowa and N Illinois.ย 

The trend this morning is clear.ย  The sharp drop-off around I-380 is showing up on multiple models.ย  Unfortunately, the way the storm is set up, the deep moisture plume gets cut off as the meat of the storm enters east-central IA.

I can believe that. I'm likely around there by now or not far off.ย

That west to east reduction in totals along 380 is an interesting feature and shows up so prevalently something like it is liable to occur. Definitely interesting how in a storm such as this, there can be a gradient from 10-11" in Benton/Iowa to about 5-6" in Jones/Cedar.

2021-22 Snowfall: (Hiawatha)

TOTAL: 10.2"

(12/28: 3.0") (12/29: 0.8")ย 

(1/1: 6.4")
