...12Z AVIATION UPDATE...

.SHORT TERM...(Today and tonight)
Issued at 143 AM CDT Sat Oct 23 2021

Key Messages:

1. Showers and thunderstorms will continue through the morning
hours before decreasing in coverage in the afternoon.

2. Severe thunderstorms are likely Sunday afternoon and evening.
All forms of severe weather will be possible.

3. Strong winds with gusts up to 30 mph will be possible Sunday
morning through Sunday evening.

4. Showers and thunderstorms will be possible again midweek next
week.

Current models show a shortwave trough progressing eastward
towards our region this morning through the afternoon. A warm
front associated with a surface low currently situated to our west
will begin to lift into the region throughout the day, allowing
Gulf moisture to be advected into the region. An increasing low
level jet is also making its way northeast into the region,
further assisting in the moisture content. As a result, scattered
showers and thunderstorms began developing overnight, and will
continue throughout the morning and afternoon.

The warm front will continue to lift throughout the evening hours,
and additional showers and thunderstorms will develop along the
front. With these storms, hail will be the biggest risk, as well
as a possibility of localized heavy rainfall. However, the highest
probabilities of these occuring will be north of us.

After the morning hours, the LLJ will begin to weaken throughout the
day before strengthening again overnight. Current analysis shows
the warm front lifting out of our area in the late evening hours,
pushing us into the warm sector and aiding in future instability.

.LONG TERM...(Sunday through Friday)
Issued at 143 AM CDT Sat Oct 23 2021

Sunday morning through Sunday evening:
An upper level negatively-tilted trough out west will begin
propagating eastward towards our region throughout the day on
Sunday before reaching our area in the afternoon/evening hours.
Ahead of this developing low pressure system, winds will begin to
increase in the early morning hours, and gusts up to 30 mph will
be possible throughout the day. For the majority of the
morning/afternoon hours, the warm sector will allow ample amounts
of daytime heating to further increase instability.

As the system moves east, a cold front will begin to push through
the region in the late afternoon/evening, with storms developing
along the front. Models show strong shear and moderate CAPE
values, with generous amounts of moisture advection as
instability further increases. This seems to promote the
development of supercells to the west of us along the front in
eastern KS and NE OK. As the front further pushes east and approaches
the region, the main question is whether these supercells will
continue to push through into the CWA, or consolidate into a line
of storms. If the supercells become the predominate type, then
significant tornadoes and large hail would pose a threat.
However, if more of a line of storms develops and pushes through,
damaging winds will be the greater threat. The SPCs Day 2 Outlook
currently has us in an Enhanced severe weather risk, and the
increased instability will allow for all modes of severe weather
to be possible.

Monday through Friday:
Once the cold front pushes through Sunday night, a cooler airmass
will move into the region. Upper level ridging will be in place as
a surface high pressure system allows for drier weather to take
place. However, this will be shortlived as another upper level
trough begins to move east towards the area. Winds will begin to
shift to a more southerly direction, allowing for Gulf moisture to
once again be advected into the region. There's still a question
as to when this system will impact the area and how intense it
will be, as the WPC Cluster Analysis Tool (WCAT) currently shows
inconsistencies between the ensembles. Regardless, showers and
thunderstorms will be possible, and further updates will be made
as confidence increases.

Lingering showers from this system will be possible throughout the
day Friday before ridging brings higher pressure and drier
weather into the weekend.

.AVIATION...(For the 12Z TAFS through 12Z Sunday morning)
Issued at 602 AM CDT Sat Oct 23 2021

A warm front is lifting into the region, and will continue to do
so throughout the day. As a result, showers and thunderstorms
continue to spread across portions of the region, and are expected
to continue throughout the morning/afternoon. Instances of MVFR
and IFR flight conditions are possible within the heavier showers
and thunderstorms as the ceilings and visibilities are reduced.
Low level wind shear will be the main threat this morning through
the afternoon for all sites.

As the afternoon progresses, storms will begin to exit the region
from west to east. As a surface low pressure system approaches the
area into tonight, expect winds to pick up and gusts up to 30
knots to be possible early Sunday morning through the afternoon.
With this system, severe thunderstorms will be likely Sunday
afternoon and evening. Future updates will go into more detail
about impacts and flight conditions.

This Hazardous Weather Outlook is for portions of the Missouri
Ozarks and extreme southeast Kansas.

.DAY ONE...Today and Tonight.

Weather hazards expected...

  Limited hail risk.
  Limited flooding risk.
  Elevated lightning risk.
  Limited non thunderstorm wind risk.

DISCUSSION...

A warm front has begun lifting north into the region and will
continue throughout the day today. Showers and thunderstorms are
developing across southeast Kansas and moving east into the
region through the early morning/afternoon hours as they track
along the front. A marginal risk for severe storms exists this
morning, with hail up to the size of quarters and lightning in
the strongest storms. Locally heavy rainfall will also be
possible.

The front will move north in the evening and overnight hours, and
the highest probabilities of strong to severe storms will shift
north of the Highway 54 corridor, with hail being the main risk.

.DAYS TWO THROUGH SEVEN...Sunday through Friday.

Gusty winds in excess of 30 mph will be possible late Saturday
through Sunday ahead of the next system.

A more potent system will move into the area on Sunday, with an
enhanced risk of severe storms Sunday and Sunday night. The
highest chances of severe storms will be in the
afternoon/evening. Tornadoes, large hail up to the size of golf
balls, and damaging winds up to 75 mph will be possible.

Additional thunderstorms will be possible Tuesday night into
Wednesday. A few strong to severe storms will once again be
possible.

.SPOTTER INFORMATION STATEMENT...

  Spotter activation will not be needed through tonight.
