.SHORT TERM...(This evening through Friday night)
Issued at 252 PM CDT Tue Oct 26 2021

Current water vapor satellite imagery shows upper level wave
approaching western Kansas with a capped airmass over western
Kansas. The airmass will continue to destabilize and once strong
upper forcing reaches the low level moisture axis, storms will
quickly initiate over western Kansas later this afternoon. Wind
shear vectors aloft being parallel to low level boundary favors
storm mode quickly becoming liner which will then move northeast
into central/south central Kansas after dark. Damaging winds from
this line of storms will be the main hazard.

Numerous showers and embedded storms will continue on Wednesday and
Wednesday night as the upper level system pivots slowly eastward
across Kansas. Heading into Thursday the upper level system will
shift east of Kansas with lingering clouds/rain showers over
southeast Kansas. Meanwhile a growing concern is the potential for
very strong to extreme north winds to occur during the day on
Thursday on the backside of this system. Model signals continue to
show very favorable downward momentum transfer of much stronger
winds aloft, and anomalously strong 850mb wind speeds running 2 to 3
standard deviations above normal. The key thing to watch for, if
we see clearing skies across central/south central Kansas during
the day on Thursday like latest models are showing. This would
elevate the risk of north winds reaching high wind warning levels,
and a high wind watch may be needed. Most trees still have all of
their leaves which increases the risk of downed tree limbs due to
abundant surface catch area.

.LONG TERM...(Saturday through Tuesday)
Issued at 252 PM CDT Tue Oct 26 2021

The upper level low pressure will move east into the Great Lakes
region by Saturday. This will allow some warming to occur across
Kansas with daytime highs near normal. Otherwise, models show
another upper wave racing eastward across the northern plains
through a fairly stout upper zonal flow regime for Saturday night
into Sunday. This will push another cold front southward across
Kansas with cooler than normal temperatures for Sunday, and
noticeably colder temperatures by early next week. Models
continue to show decent potential for winter type precipitation to
affect mainly northwest Kansas late Sunday night through Monday,
with some low potential across central Kansas on Monday.

.AVIATION...(For the 00Z TAFS through 00Z Wednesday evening)
Issued at 630 PM CDT Tue Oct 26 2021

Main aviation concern will be overnight storm chances.

Water vapor imagery shows a potent shortwave extending from
eastern WY into central NM with a surface low over far northwest
KS. Storms are expected to develop shortly along a dryline that
extends just west of KHLC to near KDDC and into far western OK.
Once they develop storms are expected to race east overnight,
reaching KRSL-KGBD in the 02-05z range and KICT in the 04-07z time
frame. The main threat with these storms will be damaging straight
line winds. Should also see some shower and storms linger Wed
late morning into the afternoon as the front moves through. So
overall we are looking for an active 24 hours as this dynamic
system moves through.

338 PM CDT Tue Oct 26 2021

This hazardous weather outlook is for portions of Central Kansas,
South Central Kansas and Southeast Kansas.

.DAY ONE...Tonight

A line of strong to severe thunderstorms is expected to move
northeast across the region tonight. The primary risk from this
line of storms will be damaging wind gusts up to 65 mph, mainly
affecting locations along and west of a Lyons to Wichita to
Wellington line. A few strong storms with wind gusts to 50 mph will
be possible later in the night across the Flint Hills and southeast
Kansas.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

Thunderstorm chances will continue on Wednesday, mainly for
locations along and east of the Kansas turnpike. While chances for
strong or severe storms appears low, there is some potential for
heavy rainfall to occur and cause some minor lowland flooding.

Very strong north winds with gusts over 50 mph are likely on
Thursday across central and south central Kansas. A wind advisory
or even a high wind watch may be issued with later forecasts.

In addition, the combination of very strong north winds and drier
air will create very high grassland fire danger levels on Thursday
afternoon. Mainly affecting central and south central Kansas.

Areas of frost are possible Friday night across much of the area.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not anticipated tonight.
