Winter Storm!? Jan 12-13th, 2019

Recommended Posts

For those in Northern Illinois...

Some guidance is handling saturation terribly. That I've looked through so far, the NAM, 3km NAM, HRRR, RAP are all much to slow with advancing the snow, some by 4-5 hours. That could play a later roll in final accumulations.

LOT

 

SHORT TERM  
  
252 AM CST  
  
THROUGH TONIGHT...  
  
A VERY SLOW MOVING AND MOISTURE RICH STORM SYSTEM WILL RESULT IN  
PERIODS OF ACCUMULATING SNOW THROUGHOUT THE DAY AND INTO TONIGHT.  
THE ONLY CHANGES TO THE GOING HEADLINES WAS TO ADD ANOTHER COUNTY  
NORTHWARD TOWARDS THE I-88 CORRIDOR AND TO ALSO EXTEND THE   
ADVISORY THROUGH 09Z TONIGHT.

Looks like we're closing in on an inch here.  HRRR/RAP show over 1/2" of precip, so we look to make a run at 6".  Always nice to see things trend in the good direction in the final 12hrs instead of the opposite lol.  

You debbed your way to 6". Congrats! ;) :D

Radar returns crawling north around here...snow literally knocking on the back door, lol...but we are getting some flakes with whatever moves overhead. Still like somewhere in the 3-5" range for IKK...

actually quite the bump in these parts along the I-88 corridor. Lot added us to the Advisory and bumped are totals from 1-2 to 3-5 inches. Fairly substantial change. Dry air still a concern.

Dry air still winning in Kankakee County. No flakes yet despite the radar returns

yup. only saving grace maybe the slow movement of the storm which could eventually overcome the issue. Noticed LOT isn't expecting snow to commence until mid morning across my zones.:lightning:

-SN and already a light coating here in southeast Naperville near DuPage/Will border. We should be in decent shape given the duration of this system. Had fairly low expectations earlier and been thinking an inch or two tops. But now I feel pretty good about hitting the range (3-4") my office forecast for this area, and at least getting into 2-3" range. Hoping for more, though small flake size this far north could be an issue.

Dry air winning in Kokomo too.  Just a dusting and nothing is falling right now.  NWS already has trended down the morning forecast by a couple of inches.

zone for Kokomo called for 5-7" at 9:33pm last night. It calls for 6" on today's 3am issuance. maybe i'm missing something.

Got hammered overnight in Macomb, IL. I estimated anywhere from 7 to 9 inches this morning. Measured 7.0" at 6am, but haven't been out since. I shot some pretty good video of numerous cars stuck and even a snowplow stuck early this morning. Some of the roads were the worst I've ever been on and I got my 4 wheel drive SUV stuck twice. Some light and variable winds is creating some minor drifting on the backside of my apartment complex.

Real nice uptick in projected accums in mby. Going to be a sharp cutoff as you get closer to the WI border, snow is having trouble making northward progression. 

Its also nice to have a daytime long duration snow storm. Been awhile since I haven’t had to watch the snow by streetlight

Already picked up 3" here near Peru. Measured 2" about an hour ago, so rates are pretty hefty. Thinking we could end up over 6", which seemed unthinkable 12-18 hours ago.

Ditto. This is a fun storm just in the fact it’s occurring mostly in daylight. The snow is definitely fluffier in nature than I had anticipated. It’s nice and powdery. If we just had any wind, this would be a whiteout.

2.5" as of 1020am. It's been snowing roughly a 1/2" per hour the last several hours.

Seeing about the same rates here.  Starting to see some bigger dendrites mixing in with the pixie dust. Hope that dry slot doesn't make it this far N.
