Man I wish we could get a couple inches of snow before the cold shows up

I'd definitely keep my eye on Tuesday afternoon. Like Coz mentioned, the sfc to 3km lapse rates are very steep(almost 9C/km) and the NAM has some good frontogensis forcing across the area I noticed the EURO and other models are picking up on that potential as well...to some extent. It would be unusual for an arctic outbreak of this magnitude to not drop at least some snow along the leading edge.

Could be some snow showers tomorrow early morning according to the HRRR and NAM. In fact us can see them in eastern Kansas right now. Best bet will be south of I-70.

There is still a chance that we'll see snow with the Arctic front.
Right now the surface front drags to much.
Argh

Upper Mississippi Valley is going to be brutal Sunday night 4-8“ of snow and temps near zero. Any wind at all is going to cause blowing, drifting and visibility problems with that much dry powdery snow. Do not envy their road crews and people trying to clear parking lots and driveways

A few flurries were falling for a couple mins in west Belleville. Radar shows a expanding light band of snow heading our way. Looks like the models nailed this one.

The GEM actually had it several days ago...I would not be suprised to see a burst of snow with it...the kind where it snows light to moderate dendrites through clouds you can see through.

The high on Wednesday is now 8* Is this arctic blast still nothing out of the ordinary?

Models still picking up on the potential for post-frontal snow Monday and an area of snow showers or squalls developing down the MO river valley Tuesday. Between these two events we should get at least a coating of snow.
I'm thinking I don't get above zero Wednesday with WCI to -30*F.

The one thing about this is the most brutal couple hours of cold are going to be Wednesday right around sunrise. Most models are fairly consistent with us going anywhere from 5-11* around 3 AM to -1 to -10 at around 6 AM with winds picking up quickly.
This is important for schools.
I agree with Brtn on him not getting above 0 Wednesday. I don’t think anyone north of 70 does.

Need tonwatch Tuesday night into early Wednesday for snow. Various models have at times shown signals...as several of you have mentioned.. that a band of snow will try to organize within the low level frontal zone along the leading edge of the last big suge of cold air. The 12z NAM has it too...and even prints out some QPF. This needs to be watched...as similar "suprise" bands have produced highly efficient snowfall within an otherwise dry arctic airmass. There was one in IA and northern MO a few years back that produced something like 10 inches of fluff.. where models had NOTHING.

I assume ratios will be quite high and snow will quickly accumulate with such cold temps. Could quickly get very messy and "white"

Looks like more flurries and or light snow showers will be possible over the afternoon per looking at upstream radar in northern Missouri and southern Iowa. This activity will mainly target areas along and north of I-70.
Meanwhile, south of I-70 get ready to get those sunglasses out as it looks like things will be clearing out for a bit in a couple hours as per satellite.

I’d love nothing more than to see that clipper come in way south. I guess we’ll watch what it does on radar.

Euro just dropped the bomb on the cold temps. Wednesday is potentially deadly cold. I hope everyone can donate to heat up st.louis this week

Models have us getting windchill values down to -22 to -25 across the metro Wednesday morning. Windchill warning criteria for lsx is -25

Looks like we have a building consensus around the coldest night now being Tuesday night into Wednesday morning...instead of Wednesday night into Thursday. How cold will simply depend on the clearing...but widespread 0 to -10 temps appear likely Wednesday morning...with single digit high temps Wednesday. Wind chills should bottom out in the -15 to -30 range...and I suspect much...if not all...of the area will get a Wind Chill Warning for this event.
