Def a marathon of snow today. Real good day to sit inside and watch some football.

NW/Illinois and Mich State/Maryland are going to be interesting games.  Looks like OSU/Mich will be mostly done before its impactful

Winners and losers so far.  Parts of southern Iowa are getting hosed by a persistent dry pocket that models absolutely did not show at all.

That dry pocket was heading this way and I was like nope, not today ma nature and she filled it back in. 

[ChiTownSnow]

Flake quality increasing overhead.  

[andyhb]

Des Moines looks like it’s getting hammered.

[jlauderdal]

Flake size and intensity has increased significantly in the last 30, we hit 10 if this is how its going to go from here on out

[OrdIowPitMsp]

Hard not to be optimistic about an overachiever here with the hi-res models showing no snow until noon, yet we’ve had parachutes falling for several hours and between 0.5”-1” down.  Very high ratio stuff

Yep, really cranking nicely right now. 

[ChiTownSnow]

Anybody got any calc on ratios thus far? 

[Chambana]

Let’s all just take a moment and appreciate the extremely fast start to winter, something that has been severely lacking the last several years. To all those in the jackpot, congrats and keep uploading pics! Still a good storm here too

Reflectivity looks great to the southwest of Chicago. Going to be a prolonged period of 0.5-1” per hour rates coming up

Heavy snow is ahead of schedule(wasnt looking good earlier), math is in our favor to hit double digits after that last uptick and it looks good upstream.  I will be on the move shortly, will see how the afternoon goes. Congrats to the board , I know its been a tough, I sense PTSD, lol.

Some specs of 25-30 dbz starting to show up on radar 

[sbnwx85]

Things are on track here. It’s been snowing for a couple of hours and we have about a half inch so far. Consistently snowing with flake size and rate gradually improving. The radar looks great.

Last hour received 0.4” at ORD, with heavier returns moving in now & vis down to 1/2SM, should be north of 0.5/hr rate going forward for awhile.

In it right now.  Its the real deal! Looks like a snow globe out here!

Pretty big bust incoming for you 

[tuanis]

Still pretty light rates here, closing in on an inch. Hope this afternoon cranks, probably another 10 hours or so of accumulating snow to go.

I see mention of a lake effect event taking shape Sunday afternoon in the NW Indiana AFD. Trying to decide whether to drop off my daughter in Chicago on Sunday afternoon (returning to GR in the evening), or have her take an early train Sunday morning from Grand Rapids instead. Temps look to be in the low 30s on Sunday which usually means the roads are OK. That said, I-94 during a winter storm warning is rarely a good idea.

A mid level dry slot still looks to overspread the area
overnight into early Sunday morning, with a quick tapering of
snow across most of the area and a likely transition to light
snow/areas of drizzle with drying DGZ and near sfc wet bulbs
warming to near freezing across south/southeast areas. A quick
transition to stronger low level CAA ensues for Sunday morning
and afternoon as stronger upper vort lobe drops across the
southern Great Lakes. This should allow for at least a 6 to 9
hour period of favorable lake effect snow showers for additional
accumulations/impacts with gusty CAA-induced winds also
expected. Some higher res guidance also suggests potential of
mesovort-type feature to accompany a sharper low level trough
passage across southern Lake Michigan Sunday morning/midday.
Have maintained the Winter Storm Warning headline into Sunday
afternoon for areas possibly impacted by lake effect snow, and
have expired the warning by 15Z Sunday for remainder of the
area. This timing may need to be moved up further as most of the
synoptic accumulating snow could depart after 09Z Sunday
morning. Lake effect snow showers should wane Sunday evening.

HRRR picking up on a heavy lake effect band/mesolow swinging through Berrien County mid-late Sunday afternoon. Would be a mess with 10-12” already on the ground.

2 inches on the ground as of 10 AM. Flake quality in last hour improved a ton. No huge flakes yet, but this new stuff is stacking nicely.

Confirmed.  Midsize flakes but starting to stack

[cyclone77]

4.5-5" here. Steady moderate snow.

[SchaumburgStormer]

About 3-3.5” so far. Cranking at .75-1” per hour 

[ChiTownSnow]

Nice mini weenie band moving overhead right now.. doesn't look to last long but short lived 1 / Hr

[Chicago Storm]

1"/hour snowfall rates here at home currently.

Central Illinois getting clobbered

Mesoscale Discussion 2239
   NWS Storm Prediction Center Norman OK
   1042 AM CST Sat Nov 29 2025

   Areas affected...parts of IL...southeast IA...and far northeast MO

   Concerning...Heavy snow 

   Valid 291642Z - 292145Z

   SUMMARY...Primary bands of moderate to sporadic heavy snow should
   pivot from south-central across southeast Iowa, and persist across
   much of central into northern Illinois through this afternoon. Rates
   around 1 inch per hour should occasionally occur.

   DISCUSSION...Long-duration snowfall event will persist through the
   afternoon, shifting eastward to the northeast of a surface cyclone
   near the western Kansas City Metro Area. Ongoing heavy snow band
   across south-central IA should largely pivot across southeast IA and
   perhaps expand as the strongest mid-level DCVA shifts across eastern
   IA this afternoon. Farther east, the persistent low-level warm
   conveyor will maintain a broad swath of moderate snow across central
   to northern IL. While the bulk of the ascent should remain beneath
   the dendritic growth zone centered around 550 mb, strengthening
   mid-level DCVA should foster sporadic bursts of heavier snow.
   Snowfall rates within these regimes should occasionally reach 1
   in/hr.

[King James]

Yeah, A+ stuff for me right now

[Baum]

Looks like the real thing.
