Area Forecast Discussion...Updated
National Weather Service Saint Louis MO
853 AM CST Thu Feb 17 2022

.UPDATE...
Issued at 822 AM CST Thu Feb 17 2022

...Impactful winter storm will bring mix of heavy snow, freezing
rain and sleet today...

Regional surface analysis drapes a slow-moving cold front across
southeast/south-central Missouri and southwest Illinois and a
developing surface low in northwest Arkansas moving along that
boundary. Of equal or greater consequence, the 32F isotherm now
encroaches the St. Louis metropolitan area, with Columbia, MO and
Quincy, IL decidedly below freezing and temperatures in the
mid/upper 30s roughly south of I-44 in Missouri and I-70 in
Illinois. According to SPC Mesoscale Analysis data, the 850mb low
is now just deepening and entering the state from the west.
Upstream observations in western Missouri indicate moderate to
heavy sleet and snow along and north of the 850mb low track.

Dual-pol radar data from KLSX clearly shows the melting layer
aloft around Columbia, MO and Quincy, IL and is confirmed by
numerous spotter reports of heavy sleet mixing with snow. These
observations also jive with a sounding launched from the
University of Missouri-Columbia this morning showing a stout warm
nose and equally-stout cold layer beneath it. Road conditions are
deteriorating from north and west to south and east as colder air
temperatures and precipitation work to cool road temperatures to
freezing. Those values are already at or below freezing in
northern and western parts of the area, and travel issues are
already occurring.

As the shortwave trough deepens and ejects from the Plains, the
surface/850mb lows will deepen and a combination of dynamic
cooling and low-level CAA will hasten a changeover from mixed
precipitation to wet moderate/heavy snow in an axis stretching
from Columbia, MO to Pittsfield, IL as previously forecast. South
of this, the warm nose aloft will likely stay above freezing and
cause sleet/freezing rain along and south of I-44 this afternoon
and evening when pavement temperatures drop below freezing. All
indications continue to point to impactful wintry precipitation
affecting the region through the evening commute. While it appears
benign at the moment for some, conditions will deteriorate with
time and travel is strongly discouraged through the early evening.

.SHORT TERM...  (Through Late Friday Afternoon)
Issued at 441 AM CST Thu Feb 17 2022

...Impactful winter storm will bring mix of heavy snow, freezing
rain and sleet today...

Here are the updated key messages regarding the storm system
that will impact the region through this evening:

Agreement in guidance:  The 00Z model suite was in good agreement
with the track of storm system. There has also been a slight
shift southward it the axis of heaviest snow.

Progression the storm system:  Timing remains the same. Heavy rain
continues over the southern part of the CWA early this morning,
while there is a brief break in the precipitation further north.
Snowfall rates around 1"/hr remain possible, especially north of I-
70 stretching from Columbia, MO to Pittsfield, IL. Further south,
sleet and icing remains the primary concern, especially for the
afternoon and evening commute. A changeover to all snow will occur
by this evening.

Winter Storm Warning/Winter Weather Advisories:  Winter Storm
Warnings remain the same.  The Winter Weather Advisory has been
expanded southward to include the rest of the CWA this afternoon and
evening because of light icing.

Precipitation totals: Snow, sleet, and icing totals are close to
the same. A swath of 6" of snow appears likely from Columbia to
Pittsfield, with higher amounts embedded within. Further south,
up to 0.15" of ice and 0.5" of sleet will be the main concern as
far as impacts go. Additional rainfall amounts of up to 1-2" can
still be expected in southeast Missouri and southwest Illinois,
but further north and west rain totals will be notably lower where
some of those totals are wintry precipitation.

Diminished severe storm potential: The cold front is moving quickly
south this morning, so only expect the potential for a strong storm
or two over southeast Missouri before the front moves south of the
area.

Forecast Details:

Latest surface analysis is showing that the front extended from
Terre Haute to just south of metro St. Louis to Branson. This
front will continue to move south this morning but will slow down
a bit midday as a surface low currently over southwest Oklahoma
moves northeast along the front through southern Missouri.
Regional radar mosaic is showing rain, heavy at times, continuing
over the southern half of the CWA, in a zone of strong low level
moisture convergence. There will continue to be potential heavy
rainfall and localized flooding through this morning.

There is a lull in the precipitation over the northwestern half
of the CWA currently, but a large area of moderate to heavy
precipitation is heading this way from Kansas and Oklahoma
associated with shortwave trough moving out of the southern High
Plains. Satellite imagery has been showing an expanding area of
cooling cloud tops ahead of the shortwave the past several hours.
Latest short term guidance including the CAMS in this
precipitation spreading across the CWA this morning. RAP
soundings are consistent with going forecast P-types with rain
changing to sleet/freezing and then to snow behind the cold front.
As mentioned above, available guidance make a minor shift in the
heavy snow axis southward associated with the deformation zone
this afternoon, but still expect the warning areas see a
combination of heavy snow, sleet and freezing today. Further south
expect a combination of lighter snow and sleet and a glazing of
ice this afternoon, so did expand the advisory to cover the rest
of the CWA.

Still expect to clear out quickly tonight, so with the fresh snow
cover and good radiational cooling, went below guidance with
around zero lows over the expected snowpack. There should be a
rebound tomorrow as winds turn out of the southwest with plenty of
sunshine. Highs will be back in the low 30s to low 40s.

Britt

.LONG TERM...  (Friday Night through Wednesday)
Issued at 441 AM CST Thu Feb 17 2022

Still looks like a dry weekend as a low amplitude ridge and large
surface high moves across the region. There will be a chance of
precipitation over the area early-middle next week a front moves
down into the area under southwesterly flow aloft.

Britt

&&

.AVIATION...  (For the 12z TAFs through 12z Friday Morning)
Issued at 539 AM CST Thu Feb 17 2022

Precipitation will fall, moderate to heavy at times, at all of
the terminals, before ending late this afternoon and early this
evening. There will continue to be mainly IFR/sometimes LIFR
ceilings while the precipitation falls along with IFR or LIFR
visibilities. Temperatures have already fallen below freezing at
KUIN and will soon fall below freezing at KJEF/KCOU so expect a
combination of sleet and freezing rain through mid morning changing
over to snow by 17-18Z. These terminals will have the potential
for moderate-heavy snow at times this afternoon with total
snowfall of 4-8" given the heavy snowfall rates. At the St. Louis
area terminals, the transition to sleet and freezing rain will
occur after 15Z with a transition to snow this afternoon. There
will be the potential for a light glaze of ice at these terminals
along with accumulations of up to 2 inches of snow.

All of this precipitation will move out this evening leaving high
MVFR ceilings. Dry and VFR conditions are expected by late in the
period.

Winds will be out of the north gusting between 20 to 30 knots
before decreasing after 06Z.

SPECIFICS FOR KSTL:

A front has moved through the terminal and winds are expected to
remain out of the north through late tonight with gusts between 20
and 30 knots. Rain will continue through 16Z before changing over
to a mix of freezing rain and sleet with a transition to snow
this afternoon. There will be the potential for a light glaze of
ice along with snow accumulations of up to 2 inches. The snow
will move out of the terminal by mid evening with 2000FT AGL ceilings
expected into the overnight hours. Dry and VFR conditions are
expected on Thursday morning.
