LOL - this. so true. -
Given a lousy season thus far, expectations for a bust are at fresh highs.

Man December was boring.

GFS nailed the totals in the end, the Euro had the track though. I always enjoy the radical totals that some models spit out... -

Anxious to see the actual snowfall map. Looks like the Euro had the best track of the models but was off on the precip amounts. As the event got closer the high resolution models also did well. Euro continues to perform well over the past few winters. -

I’d say that’s acurate. Dews here are 34 and temps nearly 36 so it may take a little bit. -

It’s actually warmed here from 33 to 35. Should drop once the next round shows up. -

BLIZZARD WARNING IN EFFECT UNTIL 9 AM CST MONDAY... * WHAT...Blizzard conditions expected. Winds gusting as high as 45 mph will cause whiteout conditions in blowing snow. Significant drifting of the snow is likely. Total snow accumulations of 7 to 11 inches, with localized amounts up to 13 inches, are expected. * WHERE...DuPage and Cook Counties. * WHEN...Until 9 AM CST Monday. Conditions ramping up between 6 PM and 9 PM this evening, first across northwest areas Edit: ninja’ed -

I’ll share my ambient. I’m in western springs, IL. Basically 294 and 88. https://dashboard.ambientweather.net/devices/public/c03162e2231692d750e01c90e9949589 -

National Weather Service Chicago/Romeoville, IL 320 AM CST Sun Nov 25 2018 .SHORT TERM... 320 AM CST Today through Monday... Powerhouse early-season winter storm taking aim on the region later today and tonight. Travel conditions are expected to become hazardous and potentially life-threatening across parts of northern Illinois, as a combination of intense heavy wet snowfall and 45 mph winds produce snow covered roads, blowing and drifting, and poor visibility. Winter Storm Warnings and advisories remain largely unchanged in coverage, though have pushed start/end times back a few hours in some cases based on consistent model trend of a slower storm system. In addition, new Winter Weather Advisory headlines are in place for Lake and Porter counties in northwest Indiana later tonight, and Lakeshore Flood Warning has been extended into Lake County IL (see separate paragraph at end of discussion). Total snowfall amounts in the 8-12+ inch range are expected across north central and portions of northeast IL, with a amounts dropping off quickly along the I-55 corridor eastward. Vigorous mid-level short wave was evident across the western Plains in early morning water vapor imagery. Associated 995 mb surface low was analyzed near Wichita Kansas as of 08Z/2 AM CST. 00Z guidance in pretty good agreement in tracking this low to near St. Louis by this evening, then east-northeast to the Champaign IL/Lafayette IN area by midnight tonight. National radar mosaic depicts a west to east oriented band of precipitation developing from southeast Nebraska into southwest Iowa, where low level cyclonic flow was inducing warm/moist advection and ascent in response to the short wave. The resulting tightening of the elevated baroclinic zone (frontogenesis) is progged to extend eastward into northern IL by mid-morning, producing a region of banded precipitation along and north of I-88 across northern IL. Forecast soundings depict an above freezing layer between 900-800 mb, which will likely result in precipitation initially falling as a mix of rain/snow in this west-east band this morning/midday. As large scale forcing for ascent increases early this afternoon with the approach of the short wave, wet-bulb and dynamic cooling is expected to cool the column enough to change precipitation over to all snow across north central Illinois. Farther east, precipitation is expected to begin primarily as rain, transitioning to rain/snow and then all snow into this evening. Snowfall is expected to intensify across north central IL late this afternoon, as moist ascent strengthens in response to increasing vorticity advection, very strong mid-level frontogenesis, steep mid-level lapse rates, and strong upper level divergence associated with coupled left front/right rear jet streak regions. Various explicit model guidance and high-res ensemble statistical output indicate the potential for snowfall rates of 1-2 inches per hour, persisting across a good portion of northern Illinois through the evening hours. During the same period, the tightening of the surface pressure gradient north of the low track will result in northeast winds increasing to near 30 mph, with gusts to 45 mph likely. The combination of heavy snowfall and very strong gusty winds will undoubtedly produce rapidly deteriorating travel conditions, which may very well become life-threatening due to poor visibility in heavy falling snow and blowing and drifting. In addition, the combination of very heavy wet snow and strong winds may result falling tree limbs and power outages. Near white-out conditions will be possible, and an upgrade to Blizzard Warnings is not out of the question later today, though in collaboration with surrounding WFO`s we elected to allow day shifts to make that call depending on how the storm develops. The strong deformation band and most intense snowfall gradually shifts from west to east across the forecast area through late this evening, eventually moving east of the area early Monday morning. This will allow snowfall to taper off and end across north central IL prior to daybreak, and shortly thereafter in the east. The exception will be across northwest Indiana, where lake effect snow showers may persist during the morning. As indicated in the first paragraph above, total snowfall is expected to range from 8-12+ inches across much of north central and far northeast IL, with amounts quickly dropping off near the I-55 corridor and areas south and east. Winter storm warnings are in effect generally for areas in the 6+ inch amounts, with winter weather advisories farther southeast where 2-5 inch amounts are expected. Snow will taper off quickly across the east Monday morning, with a few snow showers lingering through perhaps midday for Lake and Porter counties in northwest Indiana. Winds will gradually diminish and turn more west-northwesterly by afternoon. It will be chilly with highs only in the mid 20s to low 30s, and wind chills in the teens. -

Also, quoting LOT's winter outlook that I was reading last week: "If a signifiant snowfall occurs prior to start of December, probability of above normal snowfall for the fall-spring season will increase." Could shape up to be a fun winter. -

Euro seems wider, still narrow cut off, but spreads it south... Amazed at the small scale size of the storm and the punch that it will pack. I think that 4-10" is a good call. Lakefront will miss out on a lot of that but the cut off is still nice to the north. -

I was thinking the last few years the euro had a better hold on these storms. At least that model hasn’t been a budget cut victim. -

For the past # of winters, doesn’t the euro always win? I feel like this has been the 1,000,000,000,000th time -
That and I think there's convection too far south already in IA/IL thats going to dampen the whole thing.
