Area Forecast Discussion...Updated Aviation
National Weather Service Saint Louis MO
1113 PM CST Thu Jan 13 2022

.SHORT TERM... (Through Saturday Night)
Issued at 259 PM CST Thu Jan 13 2022

...Winter Storm on track for Friday Afternoon-Saturday...

It's currently the calm before the storm across the CWA with lots
of sun and above normal temps. The pockets of light rain across
parts of eastern MO and western IL exited by early afternoon with
clouds clearing quickly. This evening looks pretty tranquil with
colder air filtering into the region as high pressure settles
southeastward. Much of the latest guidance is showing a fairly
strong signal for low stratus and fog developing overnight from
central IL west-southwestward into western IL and parts of eastern
MO. In fact some of the guidance suggests that the fog could be
dense in the 10-15z time frame. I am not that confident in the
dense fog aspect but it is something we will have to watch. The
remainder of Friday morning should be rather tranquil with clouds
thickening ahead of the winter storm.

All systems still appear go for a winter storm impacting the area
starting Friday afternoon and lasting possibly into early Saturday
evening. This will be the first real widespread snowfall impacting
the entire CWA. There are still some questions on amounts and onset
times but the majority of the guidance suggest that snow will
develop sometime in the afternoon across Northwest Missouri and
west central IL in response to isentropic lift, weak large scale
forcing, and impressive mid level frontogenetic forcing. This
should lead to a rather robust and wide band of snow driven
strongly by frontogenesis. The band should then widen and
translate slowly south-southeastward on Friday Night and into
Saturday morning as both the frontogenesis and large scale forcing
attendant with the upper trof/low centered in the Plains digs
southeastward. The mid level lapse rates are 6+ DegC/km
suggesting a good response to the frontogenetic forcing and
supporting snowfall rates in excess of a half inch per hour at
times.

While there could be some brief rain at the onset of snow for areas
from central MO into southwest IL and points south, I still think
that this should be brief with low levels cooling rather quickly.
This will be a fairly wet snow with lower than normal SLRs. The
longevity of the snow in the north and intensity of the forcing
still highlights this region for the highest amounts. The WPC
forecasts, HREF, and probabilistic guidance all support this area
having potential for 6+ inches. We have decided to issue a winter
storm watch for this area starting on Friday afternoon. For the
remainder of the area this looks like a pretty solid 2-5 inch
snowfall and will eventually lead to an advisory within the next
12-18 hours.

There has been some concern about a period of heavy snowfall late
Saturday afternoon/night into early Sunday morning across southeast
MO/southern IL associated with the upper low and deepening cyclone
as it tracks to our south. The trend in the latest ensemble and
deterministic models now has the upper low digging longer and to
the east of the track yesterday, and not bottoming out until
Saturday night well south across the lower MS Valley and then
shifting east across the deep south. This track would suggest this
snow threat then will be well south of the CWA.

.LONG TERM... (Sunday through Next Thursday)
Issued at 259 PM CST Thu Jan 13 2022

There is another fast-moving northwest flow short wave trof on
Sunday night we will have to watch for a quick shot of light snow.
At this time only the operational ECMWF and a few EPS ensemble
members have been showing much of anything so the forecast is dry at
this time, and the main impact should be a reinforcing shot of cold
air.  It still appears we will see a brief warm-up on Tuesday with
heights aloft rising and low level WAA setting up but snow cover
will likely temper the magnitude. Another cold front then should
bring more cold air Tuesday night into Wednesday and result in
normal to below normal temps.

.AVIATION...  (For the 06z TAFs through 06z Friday Night)
Issued at 1110 PM CST Thu Jan 13 2022

LIFR fog/stratus is expected to advect/expand westward from its
current placement across much of central IL and impact KUIN and St.
Louis metro terminals by around 09 to 11z Friday. There is still
potential for visibilities to lower below 1 SM (currently included
with this TAF issuance); however, confidence remains low enough
to preclude explicit mention of dense fog and visibilities less
than 1 SM. Fog and stratus are less favored to reach KCOU and
KUIN, outside of a possible brief period of MVFR visibilities.
Some improvement in flight conditions is anticipated late Friday
morning into early afternoon as stratus lifts and most fog
dissipates. The exception will be fog possibly lingering at KUIN
longer into the afternoon.

A winter storm is expected to begin bearing on the region Friday
afternoon into evening in the form of a band of snow shifting
southward into the region. At this juncture, snow, possibly mixing
with rain during its onset, is set to arrive at KUIN around 21z
Friday; and St. Louis metro terminals, KCOU, and KJEF around 02 or
03z Saturday. This snow band will be accompanied by flight
conditions will lower to IFR, perhaps even eventually to LIFR.
