Area Forecast Discussion...Updated Aviation
National Weather Service Saint Louis MO
1132 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.

.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.

.AVIATION...  (For the 18z TAFs through 18z Friday Afternoon)
Issued at 1132 AM CST Thu Feb 17 2022

Surface low over north central Arkansas will continue to lift
northeastward this afternoon with precipitation north of system
changing over to wintry mix/snow for all TAF sites before exiting
after 01z Friday. KUIN, KCOU and KJEF remain in deformation zone
with visibilities below half a mile a times in heavy snow before
tapering off between 22z-23z this afternoon. In the St. Louis
metro area rain is in the process of changing to freezing rain,
sleet and snow as temperatures drop below freezing. Eventually the
wintry mix will change to all snow by 20z this afternoon before
tapering off to flurries after 01z Friday. Otherwise, IFR/MVFR
ceilings will lift and scatter out early this evening with gusty
north winds diminishing. VFR flight conditions expected for the
remainder of the forecast period with winds veering to the south
to southwest by 13z-15z Friday.
