January 24-25th Potential Winter Weather Event

It's one tenth here over 24 hours+...it's a 1" event tops.

 

No, if you look at Wxcaster maps at least, it looks like about .2", you get over .1" in a six hour period alone.

You can see the .2-.3" contour hugging most of the L Michigan shore, so just under .2" QPF I suppose.

I used to be the same way, but these last 2 winters have changed my tune and I now enjoy the 2" events much more.  I guess that's a muted positive of these less than stellar winters of the last year and a half.

I suppose if you are, say, more of a severe lover who likes a good snowstorm but not the length and repetition of winter (in fairness I do know several from this area like that)...but if you like winter, how bare ground is better than 2" of snow is beyond me. I remember a discussion several years back during one of the epic late 2000s winters (before everything was subforums) some Great lakes and east coasters got into a bit of a discussion on the subject, several of those ECers insisting the same thing...anything less than 6" is a waste of time. Well, once their jeckyl and hyde winters showed their face, the SAME posters who said this were losing sleep over a potential 1" clipper.

'copter...I was too high.  Only .9" at ORD

EDIT: bonus lol @ weenie maps

The snowfall on those NAM text outputs never makes sense. Better going by qpf...which has 0.13" at ORD (0.11", then a break, then 0.02").

 

Actually, the biggest problem here is analyzing the NAM past 60 hours...it will change 20 times, starting at 3:30 this afternoon :lmao:

More like .13, but who's counting in an overall pathetic event.  It will be a tad more near you  closer to the lake and .2" contour.  With even 12:1 ratios it would be 1.5, and 15:1 ratios would be close to 2".

lol stebo...bickering over an additional couple of tenths.  This is a non-event.

.8" vs 1.3" even at a 10 to 1, which isn't happening this event. It isn't a non event when some of your futility records go by the wayside as much as you insist on downplaying it.

This. It'll feel like a big event because we haven't had any. It'll probably lead the Chicago newscasts.

I don't understand people getting excited about high ratios for anything but stat padding.  It only takes a single day slightly above freezing to turn 6" of lake effect into 2-3" wet glop.  Real snow definitely has more staying power because it isn't just air.

So true! Going back through monthly stats for Muskegon over the years, it amazes me how the area has 20s and an 18 inch base for three weeks and then in one day with 30s and rain the total can go down to almost nothing.

Not sure if it was first, but the GFS seems content to make this mostly northern stream influenced for most. Though I recall SSC posting an image of the Euro ensembles touting the same thing. Either way, looks like a widespread very light event.

Seems like that's the way its going. But I think the GFS is skimping on the QPF over northern IL because all the models are showing some nice warm advection which should yield decent frontogenesis. This would support the slghtly higher qpf on the other models.

I would agree with this, what little moisture in the atmosphere should be pretty efficient with decent frontogenesis.

GGEM is hitting the LES for NW IN pretty nicely.  Nice 5 mm + bullseye for Lake & Porter, which is a pretty good signal from a global model.

This is what falls after 12z Friday, by which point the synoptic snowfall should be done with.

 

Hope springs eternal, eh?

Yep. No reason to sweat the details right now. Every model run is different, to an extent.

 

The Euro tends not to pick up on these subtle northern wave disturbances that well.  It struggled to show anything with the small sleet event that Milwaukee/Chicago had a week and a half ago until we were about 48-72 hours out.  Wasn't much of an event, but the Euro went from showing nothing to 0.25"QPF in a couple of runs.  In other words, I think it is slightly underdoing precip.  1-2" in general in the region sounds about right.
