.DISCUSSION...
Issued at 250 PM CDT Fri Jun 7 2024

Currently have upper ridging from West TX into NM with an upper
low over central Saskatchewan with west/northwest flow aloft
over the Plains. Water vapor imagery also shows some upper
energy moving into the Great Basin. At the surface, lee
troughing is continuing to intensify with high pressure over the
Lower Mississippi Valley.

Showers and a few storms tracked out of southwest KS this
morning in an area of 700mb warm advection and continue to
linger across east-central KS this afternoon. Additional storms
are expected late this afternoon from southeast CO into
southwest KS in a hot and highly mixed environment. However, the
bigger show tonight will for storms to develop over central
Nebraska and expand into an MCS as they track off to the
southeast early this evening. This activity will be aided by
strong 850-700mb moisture transport which will be focused into
northeast/eastern KS. Will be plenty of elevated instability and
deep layer shear for severe storms. Still thinking that our
northeast fringes will have the best chance to be impacted,
generally in a line along and northeast of Salina to Chanute.
The main limited factor for activity further southwest will be
the very warm mid level temps which should also limit eastward
progression of activity that develops over southwest KS this
afternoon.

By 12z Sat, majority of the activity will be affecting MO and
northern AR. Cold front, reinforced by outflow, will push south
on Sat, and by the late afternoon hours will be situated from
southern MO generally across or just south of the KS/OK border.
Confidence is increasing that convection will develop over the
High Plains of eastern CO/far western KS Sat afternoon in a
great upslope setup. This activity will then track southeast
through the evening and overnight hours, affecting at least the
southern half of our forecast area. Even though complex of
storms will be north of the front, still looks to be plenty
instability for large hail Sat night and great directional shear
between 850-500mb. In addition, PW values are expected to be
around 175% of normal Sat night so high rainfall rates and
pockets of flooding will also be possible. Some lingering
showers and storms will be possible across far southern and
southeast KS Sun morning but by the late morning hours the
majority of the activity will be moving off into southern
MO/eastern OK.

Once convection moves off Sunday morning, the rest of the day is
expected to be dry with cooler temps as the front pushes back to
the south of the forecast area. Confidence in precip chances
drops off considerably starting Mon and continuing through at
least Tue. The GFS slowly lifts some weak upper energy out of
NM and across south central KS Mon morning into the
afternoon/evening hours. Meanwhile the ECMWF is slower with this
upper feature and tracks it across the OK/KS border on Tue into
Tue evening. So for now will not hit the pops too hard for Mon-
Tue until models come into better agreement. While precip
chances are in question for the start of next week, confidence
is high that we will see below normal temps for the Sun-Tue time
frame with highs generally in the mid and upper 70s. Cool down
will be short lived with a return to above normal temps for Wed
and Thu.

.AVIATION /06Z TAFS THROUGH 06Z SUNDAY/...
Issued at 1246 AM CDT Sat Jun 8 2024

A complex of thunderstorms will continue racing southeast across
eastern Kansas over the next few hours, likely exiting into
Missouri by 08-10z. Thereafter, moist east-northeasterly upslope
flow may support SCT-BKN MVFR clouds at RSL-SLN-GBD by 12-15z
this morning. Another round of scattered to numerous
thunderstorms is expected to move in from the west this evening,
with additional chances for strong to severe thunderstorms and
heavy rain.
