anxiety and anticipation has taken over, this might be CMI biggest snowfall on record.
This is quite a change compared to such an abysmal start to winter in eastern IL. Has Champaign even received a 1" snowfall yet this season?

Decent sized area of "extreme" shown on the winter storm severity index forecast.

What are the chances of lightning in the the heaviest bands here? I've seen thundersnow from intense fgen bands before but I really don't know what to look for on the models to have an idea of this possibility. From my understanding, slantwise instability isn't apparent from simply looking at skew-T diagrams, and there's probably more to it than just a sharp horizontal temperature gradient. I'd love to hear input from some of the more knowledgeable members here.

Has to be a Chicago area lake effect event, here in Springfield our single 24 hour record is 17.4" from the Palm Sunday snow in 2013.
It actually wasn't. That 36" in 24 hour snow total was in Astoria, IL in 1900. There must have been some tight banding with that system, since Peoria only received half of that.

Bonkers seeing ensemble mean totals like that.
The operational 18z GFS is nearly an all time weenie run for my backyard. It would be incredible to have such a garbage season drop a monster storm of even half of what was is modeled there. I know it has happened to Chicago in recent years, but I've missed out on most of the fun in recent Februarys.

Wind chill advisory and a bare ground. Rough times here in central IL.

Lost two Japanese maples to that late January cold snap
I lost all of my rhododendrons and a lot of other plants rated for zone 4 in that cold snap, and I'm in zone 5b. Now I welcome these sudden cold snaps, since they are good for beating down invasive insect populations like Japanese beetles and emerald ash borer. Plus, what plants I had survive that snap should be able to tolerate future extreme cold here.

Oh here's a scary/cool video from this outbreak:

I have no idea what he was thinking, since models had been consistent on an outbreak setup for at least a week prior to that. I mean just the anomalous warmth in December alone is a pretty solid bet for at least some severe weather.
In Broyles defense, he did call the 3/28/20 crapvection bust 4 days out, and he was also the mastermind behind this amazing resource for violent tornadoes: https://www.spc.noaa.gov/exper/outbreaks/outbreaks-small.php#

On the SPC past events page the original day 3 is gone, as only the updated midday day3 update shows up. Was hoping to go back and have a laugh at that original day3 but it's been edited out of existence, at least on the SPC past events page.
I'm glad I saved a copy of this gem. We can't let the SPC cover up this one

I've been sitting right at the cutoff most of the day, getting a mix of sleet and snow accumulating to about 2". For such dense ratios, the snow is surprisingly dry and not sticking to the trees much.
Funny how winter is finally starting here on January 1st, just like last year.

40"+ or bust

Any amount of severe weather in that region would be historic for the time of year, so this has the potential to be absolutely insane. It's too bad storms are going to be mainly at night and moving at incredibly fast speeds.
-
It's a crazy we have a threat like this so close to the shortest day of the year, but then again, cold season has been the severe season in my area in recent years. It's a shame initiation will likely be after sunset, but regardless I'll be chasing anyway due to the rarity of the event.
This is actually quite a scary setup considering the giant area of the warm sector, the screaming storm motions, and nighttime initiation. Plus many will be caught off guard due to the fact that it's December. Even crazier is that we might get another tornado threat next week much further to the NW.

There's still a consistent signal for severe in the southern portions of this subforum for the 10th. I'd be happy without seeing a single flake of snow this month if it meant I got to see an elusive December tornado.
-
At this point I've conceded that December is merely an extra month of fall. If it's not going to snow, torch it.
Maybe we can squeeze out some cold season severe with that SE ridge that keeps showing up on the models.

I've never seen a tornado in anything above a SPC 5% tornado risk

Unless you guys think that there's actually a chance those supercells stay supercells long enough for me to drive up there, which I doubt
A nice thing about chasing a setup like this is that even if all the supercells crap out, you'll still get treated to a nice MCS at the end of the chase. Point your car into the wind and enjoy

I'd be more interested in future supercells that develop along/south of that boundary. If I was closer I'd be chasing it.

I can't believe there's no flash flood watch out in central IL for this rain band of death

It's beautiful outside now. Most of my best storms in recent years have started with anomalously warm temps the day before the main event.
HRRR is suggesting some heavy banding further west in central IL. Peoria area posters would like this scenario.
