.DISCUSSION...
Issued at 157 PM CDT Fri Aug 7 2026

A sprawling mid/upper-level anticyclone over the Great Basin and
Four Corners is amplifying and expanding eastward across the Rockies
into the central and southern Plains through the weekend. This
pattern favors warming and sporadic isolated storm chances across
Kansas.

For this afternoon and tonight, a few weak boundaries appear in
observations. The first is expected to remain south of the area,
while the other is to our north across southern Nebraska. The broader
environment remains warm and moist, but with significant capping in
place, the likelihood of storms developing around our area is
minimal. An MCS may develop in central Nebraska and push southeast,
potentially clipping our far northeast late tonight into tomorrow
morning as the low-level jet increases, but the latest model runs
have grown increasingly pessimistic in this scenario playing out.
Generally, a hot and dry forecast is favored through early next week
as the core of the upper ridge shifts farther east over the
central/southern Plains, reinforcing a hot air mass over much of
Kansas while a surface boundary slowly meanders nearby.

Weak perturbations riding the northern periphery of the ridge and
the lingering boundary will periodically bring low chances for
showers and thunderstorms, mainly during the late afternoon and
evening hours, particularly across north central and far northeast
Kansas closer to the frontal zone. However, stronger capping and
subsidence under the ridge suggest that storm coverage will be
limited and spatially inconsistent, with many locations remaining dry
for extended periods despite the presence of the boundary. Heat
indices in the low 100s are once again likely for the area beginning
tomorrow and lasting into next week.

Overall, the forecast remains characterized by episodic, mainly
boundary-focused storm chances against a backdrop of increasingly
oppressive heat as the ridge peaks over the central Plains.
