...WIND CHILL WARNING REMAINS IN EFFECT UNTIL 6 PM CST MONDAY...
...WINTER WEATHER ADVISORY REMAINS IN EFFECT FROM 6 AM SUNDAY TO
6 PM CST MONDAY...
...WIND CHILL ADVISORY WILL EXPIRE AT 6 PM CST THIS EVENING...

* WHAT...For the Wind Chill Warning, dangerously cold wind chills
  expected. Wind chills as low as 28 below zero. For the Winter 
  Weather Advisory, snow expected. Total snow accumulations of 2 
  to 4 inches.

* WHERE...In Illinois, Brown IL County. In Missouri, Monroe MO 
  County.

* WHEN...For the Wind Chill Warning, until 6 PM CST Monday. For 
  the Winter Weather Advisory, from 6 AM Sunday to 6 PM CST

  conditions could impact the morning or evening commute. The 
  cold wind chills could cause frostbite on exposed skin in as 
  little as 30 minutes.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Wind Chill Warning means the combination of very cold air and
strong winds will create dangerously low wind chill values. This
will result in frost bite and lead to hypothermia or death if
precautions are not taken. If you must venture outdoors, be
certain to dress properly, with several layers of light-weight,
loose fitting clothing and making sure that all exposed skin is
covered. 

A Winter Weather Advisory for snow means that periods of
accumulating snow will primarily cause travel difficulties. Roads
may rapidly become slippery once the snow begins, so motorists
should plan for a slower than normal trip. Be especially alert
when approaching bridges, overpasses, and curves.

...WINTER WEATHER ADVISORY REMAINS IN EFFECT UNTIL 6 PM CST
MONDAY...

* WHAT...For the Wind Chill Warning, dangerously cold wind 
  chills. Wind chills as low as 25 below zero. For the Winter 
  Weather Advisory, snow. Additional snow accumulations of 3 to 
  5 inches.

* WHERE...Moniteau MO, Cole MO and Osage MO Counties.

* WHEN...For the Wind Chill Warning, until noon CST Tuesday. For 
  the Winter Weather Advisory, until 6 PM CST Monday.

* IMPACTS...Plan on slippery road conditions. The hazardous
  conditions could impact the morning and evening commutes on
  Monday. The cold wind chills could cause frostbite on exposed 
  skin in as little as 30 minutes.


PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Wind Chill Warning means the combination of very cold air and
strong winds will create dangerously low wind chill values. This
will result in frost bite and lead to hypothermia or death if
precautions are not taken. If you must venture outdoors, be
certain to dress properly, with several layers of light-weight,
loose fitting clothing and making sure that all exposed skin is
covered. 

A Winter Weather Advisory for snow means that periods of
accumulating snow will primarily cause travel difficulties. Roads
may rapidly become slippery once the snow begins, so motorists
should plan for a slower than normal trip. Be especially alert
when approaching bridges, overpasses, and curves. 

The latest road conditions can be obtained on the Internet at

  snow could significantly reduce visibility. The hazardous 
  conditions could impact the morning or evening commute. The 
  cold wind chills could cause frostbite on exposed skin in as 
  little as 30 minutes.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Wind Chill Warning means the combination of very cold air and
strong winds will create dangerously low wind chill values. This
will result in frost bite and lead to hypothermia or death if
precautions are not taken. If you must venture outdoors, be
certain to dress properly, with several layers of light-weight,
loose fitting clothing and making sure that all exposed skin is
covered. 

A Winter Weather Advisory for snow means that periods of
accumulating snow will primarily cause travel difficulties. Roads
may rapidly become slippery once the snow begins, so motorists
should plan for a slower than normal trip. Be especially alert
when approaching bridges, overpasses, and curves.

Area Forecast Discussion...Updated Aviation
National Weather Service Saint Louis MO
1117 AM CST Sat Feb 13 2021

.SHORT TERM...  (Through Late Tonight)
Issued at 419 AM CST Sat Feb 13 2021

The main focus today and tonight will remain dangerously cold
temperatures/wind chills. Bitterly cold air continues to pour into
the area producing dangerous wind chills of at least 15 below zero
across central and northeast MO and west central IL early this
morning, while elsewhere wind chills were in the 5 to 15 below
range. These values should continue into the first part of the
morning and then improve from late morning into the afternoon as we
see some minimal temperature rebound from the morning lows. The
exception will be far northeast MO and west central IL where ambient
air temperatures will remain so cold that wind chills remain near 15
below into the afternoon, hence the advisory will be extended
there.

Tonight the east-southeastward movement of the Lake Winnipeg
upper low and the ensuing confluent flow to it's south will help
bring a reinforcing surge of even colder air associated with
surface high pressure building further into the region. The
southward spread of this bitterly cold air mass and colder
temperatures tonight will result in wind chills ranging from
around 25 below in northeast MO and west central IL to near 15
below across southeast MO and southern IL. These dangerously cold
values will persist through Sunday and into Monday. Therefore a
wind chill warning has been issued tonight through Monday for far
northeast MO and west central IL, with a wind chill advisory for
the remainder of the area into Monday.

As far as precipitation today, pockets of light and generally non-
accumulating snow will diminish this morning across northeast MO and
west central IL with scattered flurries this morning elsewhere.
Other than the possibility of spot flurries tonight, I think tonight
will remain void of precipitation.

Glass

.LONG TERM...  (Sunday through Friday)
Issued at 419 AM CST Sat Feb 13 2021

The screaming message from last night has not changed 24 hours later
with bitterly cold air/record temperatures, dangerously cold wind
chills, and accumulating snowfall the highlights into next week.
Record low max temperatures Sunday into Monday still look like a
slam dunk, however I have less confidence in record low temperatures
due to persistent cloud cover. Still generally all but southeast
MO and far southwest IL will have mins below zero through Monday
and the entire CWA may have mins below zero on Tuesday morning.

The increasingly active upper air pattern starting later this
weekend and continuing into next week will bring accumulating
snowfall to the region first Sunday into Monday. This first event
will come in two waves. On Sunday the consensus is the first wave
will be focused from central MO into west central IL associated with
a weak impulse in the southwest flow aloft and attendant mid level
frontogenetic forcing. Snowfall amounts with this wave generally
look light, around an inch or less. The more substantial snowfall
will occur with the second wave centered on Sunday night and Monday.
The best focus for this snowfall will centered along and south of I-
70 associated with increasing low-mid level frontogenetic forcing
and increasing large scale forcing occurring ahead of a migrating
upper trof. Until late Monday the models lack a coherent 850 mb
low which could offer even greater snowfall potential. However
this combination of persistent frontogenetical forcing and large
scale support with the trof, and very cold temperatures yielding
high snow ratios, should still produce a solid measurable
snowfall of 2-5 inches across much of the CWA with the highest
amounts along and south of I-70 in the 4-5 inch range. The NBM and
GEFS exceedance probabilities support this region for the highest
snowfalls with good support for 4+ inches. If the amounts stay in
these ranges then this would be an advisory level event, and
those headlines would likely becoming later today.

We are still eyeing another system in the Wednesday-Thursday time
frame. There are some rather significant differences in the
models with regards to the depth and speed of this next migratory
upper trof, with some solutions indicating possibly a light snow
and others a rather classic winter storm. Like last night,
confidence in the specifics remains low. The very cold, well
below normal temperatures will continue mid-late week.

Glass

&&

.AVIATION...  (For the 18z TAFs through 18z Sunday Afternoon)
Issued at 1116 AM CST Sat Feb 13 2021

To start the period, a band of light snow is positioned over the
KSUS, KSTL, and KCPS terminals. Recent radar trends indicate this
band weakening as it moves eastward, and I anticipate this trend to
continue through the early afternoon. These same three terminals
will be on the western edge of MVFR ceilings through the afternoon,
and while these could creep over the terminals, my confidence is
high that they will stay to the east.

Another band of snow is moving eastward through northern Missouri,
and confidence is currently high that it will dissipate before
reaching the KUIN terminal this afternoon. However, low-level
moisture from the remnant band may still be high enough to produce
lower clouds over the terminal, bringing MVFR ceilings for a brief
period this afternoon.

Our attention then turns to the next round of winter weather on
Sunday. The chance for snow will increase near the end of the KUIN
and KCOU forecast period and at the end of the longer KSTL
forecast period as snow moves eastward into Missouri. Confidence
in the exact timing and placement of more impactful snow is low at
this time, so have used VCSH to account for time of greatest
confidence in the start of potential impacts.
