.SHORT TERM...(This evening through Saturday night)
Issued at 407 PM CDT Wed May 26 2021

Current satellite water vapor imagery shows a healthy upper level
wave moving eastward across Montana and Wyoming, and this system
will move into the Dakotas for tonight. Elevated severe storms
developed this morning/early afternoon along mid-level frontal
boundary over northwest/central Kansas. Latest thinking is that
moist upslope low level flow will generate storms this afternoon
across the high plains region of western Nebraska which will then
travel east/southeast tonight along that mid-level frontal boundary.
A large scale forward propagating MCS is likely with damaging to
destructive winds being the primary risk overnight. The track of
this MCS could clip parts of central KS(I-70 corridor) with the
better chances remaining north over southern Nebraska/northern KS.
This MCS should create a well pronounced outflow boundary that will
surge southward and become a focus for storms re-developing on
Thursday. Where this boundary ends up will be key for Thursday
afternoon severe weather location. Shear vectors look be more
parallel to the surface frontal boundary/outflow boundary which
should create a more rapid liner storm mode development, with
damaging winds and large hail being the main risk. A few tornadoes
could be possible for any initial discrete cells, however the risk
looks lower due to quick evolution to liner mode. Given an expected
very unstable airmass south of the boundary the line of storms could
produce higher end severe weather.

Another area for storms possibly redeveloping this afternoon will be
along the dry-line in southwest Kansas. A very unstable airmass with
MLCAPE values over 3500 J/kg and favorable wind shear aloft supports
supercell development. Any storm that develops along the dry-line
should remain discrete with 0-8km shear vectors being perpendicular
to the dry-line boundary. This activity will move eastward into a
favorable tornadic environment this evening with increasing low
level jet and boosting values of 0-1km SRH. This activity could
reach parts of central/south central Kansas late this evening.

Surface high pressure with cooler and much drier air will overspread
the region for Thursday night into Friday, as upper trough shifts
eastward into the Great Lakes region. This will stabilize the
atmosphere over Kansas with dry weather expected for Thursday night-
Saturday.

.LONG TERM...(Sunday through Wednesday)
Issued at 407 PM CDT Wed May 26 2021

Models show upper level ridge axis shifting slowly east on Sunday
with a couple upper waves moving across the central plains for
Sunday-Tuesday next week. This looks to bring more rounds of
showers/storms to the region. Meanwhile long range models show an
upper trough pivoting eastward across the central plains on
Wednesday, and if this signal remains consistent then weather
pattern would shift precipitation east of Kansas.

.AVIATION...(For the 06Z TAFS through 06Z Thursday night)
Issued at 1258 AM CDT Thu May 27 2021

Low level moisture transport continues to stream to the NE into
southern KS. This moisture advection is feeding a bowing line of
convection currently moving across southern KS. Expect this complex
of storms to continue to move to the east early this morning and
affect the KCNU taf site. So will go with a SHRA/VCTS and some
variable wind gusts for this complex.

The rest of the region will see a lull from the convection
overnight, as most of the convection moves NE of the forecast area.

A frontal boundary will push southeast across the forecast area
during the daytime hours. Expect this front to be located close to
the KS Turnpike by around 18z, with convection expected to develop
along this boundary for Thu afternoon.  So will go with VCTS and
TSRA for the KICT/KCNU and KHUT taf sites.  Expect this convective
chance to move rapidly SE into NE OK, by the early evening hours on
Thu.

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

.DAY ONE...Tonight

Severe storms will affect central Kansas through the early evening
hours with very large hail, damaging winds, torrential rainfall,
and a few tornadoes possible.

More storms look to develop over southwest Kansas which would move
eastward, and could reach central and south central Kansas after 10
PM. Very large hail, damaging winds, and a tornado would be possible
with this activity.

In addition, thunderstorms will develop over southwest Nebraska then
track east southeast tonight. The storms will evolve into a line of
storms with the primary risk being damaging winds of 60 to 80 mph,
and heavy rainfall. This line of storms could impact central Kansas
late tonight.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

A cold front will move across the area Thursday afternoon into
Thursday evening. Locations generally along and southeast of the
Kansas Turnpike will have the greatest risk of severe storms.
Severe storms appear likely with golfball to tennis ball size hail,
damaging winds of 60-70 mph, and perhaps a tornado or two. Heavy
rainfall and localized flooding will also be possible.

More rounds of storms will be possible for Sunday through Tuesday
across the region.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not anticipated tonight.
