I've had some periods of moderate to even heavy snow today with very little additional accumulation. Melting and compaction are outpacing the snowfall. Getting some sleet and rain mixing in a bit too. Nearly 0:1 ratios . Still at about 10" so far.

The ol northern shift within 24-36 hours rarely fails. When will you Yankees quit stealing my snow? Yeah, and 90% of the time when we need a north shift it doesn't happen. It's very tough to get a nice, widespread major winter storm with 6"+ amounts across the board. A couple degrees colder and this would have been an absolute monster, record shattering snow storm. It's still a huge storm in a fairly localized area though...1 in 25 year event in those areas, IMO.

I'm seriously considering unloading on the next flock of snows that fly 20 yards over the house. I'm on my way...

A quick check of the gfs...Good point from another poster on the climatological odds of seeing two high impact storms a week a part. I would normally be the first to dismiss the possibility of a high impact storm next weekend for that reason. However, this year is different. I'm a little apprehensive that the push of cold air may be underdone on the GFS and that this could suppress next weekend further south, but the gfs models have been fairly consistent with a mid ms storm system. QPF is a lot lower with the next storm system, but that's because the upper level low is more of an open wave that moves through. I'm very much interested in next Friday and Saturday for another potential high impact system, and I continue to be interested in the very active wx pattern for the following week as well before a big dome of high pressure dominates the mid section suppressing any southern stream activity for the remainder of the month. Why do I think this year is different? we are locked in a pattern of repeat southern storm systems. The transition of the arctic air mass in the pattern change has been shown to be gradual, with a two steps forward/one step back kind of progress. There are differences with this next storm: more cold air, storm moving a bit faster from the southern plains, and a stronger high pressure which will mean more winds that will likely bring us more of a drifting of the snow. It's a system of interest to me, but if it doesn't work out, there's more upstream.

Nice spray of dendrites now...biggest flakes of the event right now for sure. Still just a moderate(1/2mi) clip.

Did anyone else make french toast this morning? I used texas toast and 15 eggs! I stuffed 4 pieces into me. Hubby and 2 teen sons ate 18. Where do they put it? So yes, I got bread, milk and eggs on Thu in preparation. I made French toast because I was going to make pancakes and discovered I was out of flour and didn't have enough sugar. I did have enough sugar and vanilla for French toast though.

Beaker, I think you are right about late month and February...I think we are in for a potentially severe stretch of winter weather and this storm is just the appetizer.

We are due for a big February storm. Surprisingly the last 6+" storm in February at KSTL was 25 years ago.

Beaker, I think you are right about late month and February...I think we are in for a potentially severe stretch of winter weather and this storm is just the appetizer. History shows us that we get big snows in February during winters like this...weak el nino and an active southern stream. We may have a brief break toward the end of January but that will be because cold will suppress the storm track and places like cgi and pah will be in the spotlight; but as the storm track begins to seasonally migrate back north and it will, the migration will be very slow, as it fights infusions of cold, and I am seeing multiple shots of storms through the mid section.

19Z RAP absolute just clobbers the metro hard with another 5-8" of snow with the small but stout deformation zone.

beaker have you gotten much since this morning?
I too have had several periods of decent snow. Even right now I have large flakes but it's just not adding up. I've had 1" or less since 8am.
It's 33F at my house.

For Belleville, IL the RAP flips us back to snow around 5-6PM then just dumps on us, probably hamsters from 6PM to nearly midnight with 1-1.5" per hour rates. Could be pretty sweet.

We are due for a big February storm. Surprisingly the last 6+" storm in February at KSTL was 25 years ago. I remember the two February 1993 storms. Conceptually, I'm thinking this February has the potential to be much snowier than then as well. I believe many of us had 20 plus inches that year.

Eyeballing the WV loop it looks to me that I-44 corridor would be a favored location for additional accumulations. That is between the southern and northern edges of the weakening 700mb and 850mb lows, respectively. That roughly matches the RAP/HRRR guidance. But are we going to get improved accumulation rates...?

It's 33F at my house. my depth has stayed the same. I'm guessing compaction is fighting whatever is fallen. That's why my storm total turned into an estimate of 11 inches. I can kind of tell the fresh snow because it is fluffier. I agree, no more than an inch though even though I've had a couple brief intense showers.

How far south does the snow get with the RAP Marissa is shown to just miss it by a hair to the northwest. Very razor sharp gradient across St. Clair County with 8" to the far northwest of the county and a dusting at best for the far southeastern part with Freeburg the southeastern boundary of 1" or better
E. St. Louis: 7-8" Dupo: 7" Cahokia: 6-7" West Belleville: 5.5 to 6" Belleville (downtown) and Swansea: 4.5 to 5" Millstadt: 6" East Belleville: 3 to 3.5" Freeburg: 1-3" Red Bud: 1-2" Smithton: 1-2" Marissa: D-.5"
Above is snowfall for select towns and cities in St. Clair county per the latest RAP. Using 10:1 Ratio Subtract 20% for Kuchera Method.

After looking at the zoomed images that coz posted, I would tend to agree. I think accumulations will pick up again once the sun goes down and CAA begins.

I don't want to hear anyone complain about their 8-10 inches being compacted. There's currently a steady rain falling on what's left of my 4 inches . I don't want to hear anyone complaining. 12 drinks deep and zero blackjacks lol.
