Precip is certainly scooting along. Noon looks like a good call. The Mrs. is mad at me because I cancelled a grooming appointment for one of our dogs where pickup was supposed to be about 1:30pm or 2:00pm today. So...if anyone knows any dog groomers in the High Ridge/Fenton/Valley Park area that aren't booked solid 6 weeks out...I could use a little help!  |

Some of this reminds me of a movie scene. Helen Hunt: Everybody! Get inside quick! Big cold front coming!
Bill Paxton: its already here!

Visibility quickly lowering with dendrites falling. Already getting some BLSN with the dusting on the ground.

related discussion:
DISCUSSION...Recent surface observations from far eastern IA show
visibility reductions down to 1/4 mile at times under a persistent,
though loosely organized, snow band. Based on latest RAP
mesoanalysis, this band is primarily being driven by broad scale
ascent ahead of a deepening upper low over the central Plains,
augmented by more focused frontogenetical lift within the 850-700 mb
layer. Forecast soundings indicate that much of this lift coincides
with a 100-150 mb deep dendritic growth zone, which is likely
yielding moderate, to at times heavy, snowfall rates up to 1
inch/hour. Concurrently, strong cold advection behind the surface
front is supporting frequent wind gusts between 25-35 knots from
eastern IA to central MO. The combination of these winds and
moderate snowfall rates will likely result in periods of
blizzard/snow squall conditions with visibility reductions briefly
falling to 1/4 mile under the snow band as it continues moving east
through early/mid afternoon.

here's the disco for the meso disco
SUMMARY...Sporadic, short-lived blizzard/snow squall conditions will
be possible under a mesoscale snow band as it tracks east across
parts of eastern Missouri and western Illinois through early/mid
afternoon.

Looks like radar is showing snow breaking up quickly just West of Columbia - One quick hit of snow maybe 1-2 hours = 1-2 inches

Could the NWS issue a snow squall warning, or does the WSW cover it?

Could the NWS issue a snow squall warning, or does the WSW cover it? we are under a winter storm warning, there will be no snow squall warning. And per TK, it will snow for 3 or so hours not an hr or 2. It's already snowed an hour here in Union and the main band is just getting ready move in |

Looks like radar is showing snow breaking up quickly just West of Columbia - One quick hit of snow maybe 1-2 hours = 1-2 inches The radar is overshooting a lot of the snow with the DGZ being so low. The system is also going to be strengthening as it moves into the area so the precep shield will expand. |

Flakes flying pretty good in Edwardsville now. Looks more impressive in person than what radar is showing.

The 'streamers' really show up on composite. Pretty sure one was over 99 when he mentioned it picking up. I am hoping that the radar is 'losing' the echos from further down south. Looking at Spf radar I should have no issues. Almost seems like wherever that band sets up in a east/west orientation should give some nice 'bullseyes'.

I have very little snow and almost looks bright enough that the sun might peak through. WTH Temp down to 17* 7 miles west of De Soto.
Edit: Must be that very small clear spot over me on Composite radar.

Area Forecast Discussion...Updated
National Weather Service Saint Louis MO
1119 AM CST Thu Dec 22 2022
.UPDATE...
Issued at 1111 AM CST Thu Dec 22 2022
A band of moderate to heavy snow continues to move eastward
through central and northeast Missouri as well as west-central
Illinois late this morning. Several observations have shown 1/4SM
+SN and see no reason short durations of near-blizzard conditions
will translate across the rest of the area through the day.
Short-term guidance shows this band of moderate to heavy snow
slowing down a bit as the mid/upper level trough amplifies
overhead. Have therefore boosted snow totals ever so slightly
across eastern Missouri, and about 0.5-1.0" in southeast Missouri
and southwest Illinois where snow will continue past dusk.
The other change was to fasten the arrival of the subzero
temperatures and cool temperatures a bit overnight tonight.
Upstream observations show widespread readings at or below -10F in
the mid-Missouri Valley. Strong low-level cold air advection also
continues through the night with 850-hPa temperatures approaching
-30C. This resulted in wind chill warning in northern sections of
the CWA was moved up to start at 18Z. No further changes to
either winter storm or wind chill warnings at this time.
