Natester Posted December 17, 2016 Share Posted December 17, 2016 Snowing cats and dogs outside. Hope to pick up 2-3 inches from this before this band moves out. Link to comment Share on other sites More sharing options...

ILSNOW Posted December 17, 2016 Share Posted December 17, 2016 National Weather Service Chicago/Romeoville, IL 308 PM CST Sat Dec 17 2016 .SHORT TERM... 308 PM CST Through Sunday... Will be issuing a Winter Storm Warning for Lake and Porter counties in Indiana for the likelihood of an intense band of lake effect snow moving across northern portions of the counties later this evening through the overnight hours. Up to 3 to 7 inches of snow could fall where the most intense snow occurs, with snowfall rates of 1"+ per hour likely. In association with or just behind the most intense portion of the band, winds will gust from the north-northwest to 35-40 mph, causing significant blowing and drifting snow and substantial visibility reductions. Made no changes to the Winter Weather Advisory and Wind Chill Advisories for the remainder of the area. Castro Link to comment Share on other sites More sharing options...

Hoosier Posted December 17, 2016 Author Share Posted December 17, 2016 I just want to illustrate how things changed in the past 24-48 hours. Here are the 48 hr model progs from 12z Thursday, valid at 12z today. The general thought (at least among non-NAM models) was that this surface low near St. Louis would continue northeast as a sub 1000 mb low. If you look at a current surface map, you see something quite different... a weaker/strung out pressure pattern. These model runs were only 48 hours ago. It's a good example that things can sometimes change pretty substantially, even in today's model world. This was not simply a case of the track/strength being on point and somebody's backyard ending up in a mini screw zone. This was an error on a larger scale.

cyclone77 Posted December 17, 2016 Share Posted December 17, 2016 Light snow started up a bit ago. Nice dendrites. Looks like it will be hit and miss for the next hour or two before the main band finally swings through. Hoping for an inch of fluff, but looks like best shot at 1"+ will remain to the west where the bands are sort of stalled. Picked up 0.2" of snow and a glaze of freezing drizzle so far from this storm. Bring on the cold. Link to comment Share on other sites More sharing options...
cyclone77 Posted December 17, 2016 Share Posted December 17, 2016 Probably the most insane blue norther I can remember. Temp in San Angelo TX hit a record of 84 a short while ago. They're still basking in the warmth at 80 with a nice southwest breeze. HRRR takes them down to 19 degrees by Midnight!! Pretty amazing. Link to comment Share on other sites More sharing options...

That is 11/11/1911 caliber right there. Anyways, super heavy snow right now as I'm right under that dark green banding right now. The bad news is that it won't last long as it'll shift off to the east rather quickly. I'll most likely pick up a quick inch from this out of the inch that I already got when the snow started.

In fact a met from fb mentioned they have a shot at a record low before midnight arrives, which would mean min/max in the same day, ala 1911. 2" out of these bands today is a def win to be sure, I'd take that in a heartbeat lol.

Natester Posted December 17, 2016 Share Posted December 17, 2016 Intense band is pretty much done here. Still snowing moderately. Only lasted about 17 minutes, not enough time to pick up a quick inch. Link to comment Share on other sites More sharing options...

Picked up 0.2" of snow and a glaze of freezing drizzle so far from this storm. Bring on the cold. Things are winding down here. I don't know how to measure snow when it's totally wind-blown. More exposed surfaces have 0.5 to 2 inches on them but there are drifts all over the place that are about 4-8 inches deep. I'll say we did pretty well.

ConfusedKitten Posted December 17, 2016 Share Posted December 17, 2016 Things went south really quick here, I wasn't really watching the weather but apparently in the last couple hours my driveway has turned into a skating rink. We've only had some freezing drizzle, but I guess that'll do it. Link to comment Share on other sites More sharing options...
Jackstraw Posted December 17, 2016 Share Posted December 17, 2016 KIND increased ice accumulations up to almost 1/4 inch tonight and snow 1-2 in. north of I70. Hope folks learned a lesson last night, it'could be much worse on the roads tonight. Link to comment Share on other sites More sharing options...

Looks like you guys are about to really get into the icebox behind the departing snow. 5 above in Ankeny already. Nice 50-75 mile wide band of moderate snows from southeast Iowa down into eastern KS. Probably near 1"/hr rates within it. The trick is getting into the band and staying under it for awhile lol. Still getting bursts of snow here at times. Just when it looks like it really wants to start ripping it shuts off. Looking forward to the steadier snows in another 1-2hrs. Link to comment Share on other sites More sharing options...

Powerball Posted December 17, 2016 Share Posted December 17, 2016 It looks like an area of freezing rain has blown up to the SW. Hopefully, the temp profiles can cool off before it gets here to change it all to snow, but it's hauling ass. Link to comment Share on other sites More sharing options...

hawkeye_wx Posted December 17, 2016 Share Posted December 17, 2016 I've picked up a couple inches from the deformation snow bands this afternoon. During the peak I picked up 0.8" in one hour. Link to comment Share on other sites More sharing options...
Chicago Storm Posted December 18, 2016 Share Posted December 18, 2016 HRRR did well again with the first wave, and if correct it looks interesting for the immediate Chicago area overnight.Synoptic snows are lake enhanced, before pure LES takes over in NW.

Synoptic snows are lake enhanced, before pure LES takes over in NW. IN. 00z run got even a little better for the immediate Illinois shore, with more 6+ amounts on that Kuchera map. Will be interesting to watch. Looks a little shifty at this point but if it decides to hang up somewhere very long, I may hop in the car for a late night run.

That HRRR map would have you right on the 6-7" threshold right? EDIT: Ripping pretty nicely here now. Unfortunately the band is now transient after being stalled in Iowa for hours lol.
