Chicago Storm

This is gonna be one of those situations where you don't really have a full/total handle on how it's going to go until we're deep into it, for the metro/NE IL that is.

our resident wisconsin palm aficionado is tth now. .

A lot of noise on guidance over the past 24 hours. Most 0z guidance shifted a bit NW, and now most 12z guidance shifted bit SE.

They pretty much are forced into using the NBM.

.

Two weekend waves have nearly doubled seasonal snowfall totals at ORD, from 3.9" to 7.4". Friday night-Saturday morning wave snowfall totals... ORD - 1.9" MDW - 1.6" RFD - 1.3" Saturday night wave snowfall totals... ORD - 1.6" MDW - 0.5" RFD - 0.5"

I’ve been at the point for years now that the only things that excite/interest me snowfall wise are big dogs (or at least medium dogs), record/near record occurrences, and abnormal/significant conditions. This one will be none of the aforementioned most likely, so overall interest is low. However, looks like a solid 2-5”/4-7” kind of situation from SE to NW across the area, with lower amounts near the lake and downtown. .

i guess we've reached that point...

0z Euro says I see you, and I raise you… .

Forgot to mention it at the time, but while downtown for NYE/NYD I noticed some trees were budding.

That’s as exotic as it gets… .

lol 0z GFS late next week… .

The snow for tonight sort of came back from the dead, as it was shown a few days ago, before vanishing. Looks like a 1-3" type of situation for tonight into Saturday morning across the area.

It had a run similar to the 0z a day or so ago as well.

i don't know why they still waste their time with these. they're always so bad.

zzzzz .

I'll probably become more interested come Saturday, but until then it's a bit too early. There are a few players to watch that will factor into the evolution of this one, including what exactly happens with the lead weekend storm system.

December 2023 finished tied for the 4th warmest December on record in Chicago. Top 10 Warmest December's 1. 43.4 - 1877 2. 40.7 - 1889 3. 39.7 - 1923 4. 39.0 - 2023 4. 39.0 - 2015 6. 38.4 - 1931 7. 38.0 - 2021 8. 37.8 - 1881 9. 37.7 - 1918 10. 37.4 - 1971

i’ll throw up a zzzzz to that. .

Beat me to it, as I was going to type up something while I’m the train this afternoon heading downtown. This is the first evolution of the new pattern, which some may even consider a new pattern in itself. Winter lovers, your time has come. I’ll be boxing up the palm tree this week. One tidbit of note is that we will be falling short of SSWE “criteria”. But it doesn’t even matter in the end, given the substantial amount of warming and disruption there currently is and will continue to be for a while. As you mention, the high latitude blocking is being shown consistently (And at times fairly significant looking), and the effects of the warming appear as though they will be real. .

0.9” of snow at ORD thus far today. That 0.9” plus the 0.3” on the month going into today brings the monthly total to 1.2”, which knocks this December out of the top 10 least snowy. .

Solid meso-low tonight on the western shore of Lake Michigan, between Manitowoc and Algoma, WI. .

the useless cfs, posted with love for our wisconsin brethren… .

S WI, E IA and NW IL will end end up the winners with this second round. Should end up with advisory level snowfall accumulations in that corridor. .
