.DISCUSSION...
Issued at 354 AM CDT Sun Jul 20 2025

As of 330 AM Sunday morning, zonal midlevel flow continues with the
ridge axis across the southern MS valley. The most robust convection
is ongoing on the nose a 30-35 kt LLJ across southern IA. Broad
low/mid level WAA continues to produce weak showers/storms across
portions of central KS. As the LLJ veers through sunrise, anticipate
this activity to dissipate. The remnant surface trough axis, which
has been reinforced by convective outflow extends from northeast KS
through central KS and into west-central KS. A weak midlevel
perturbation, which is currently within the central Rockies, is
forecast to eject into WY/NE later today. This should result in
isolated development along a dryline across portions of
CO/WY/NE. While the strongest forcing for ascent is likely to
remain north of the forecast area, sufficient convergence along
the aforementioned surface trough may result in isolated
thunderstorm development by late afternoon in the vicinity of
I-70. A deeply mixed boundary layer, characterized by dew
depressions near 40 degrees, will result in inverted-V profiles.
As such, any storm will be capable of wind gusts near 60 mph.
This zone of convective potential should dissipate with sunset.
In regards to extreme heat, heat indices up to 110 degrees are
expected area-wide this afternoon. Refer to the Extreme Heat
Warning for additional details. Additional WAA driven
showers/storms may emerge into the overnight hours across
central and south-central KS. Severe weather is not expected
with this activity.

For Monday and beyond, the midlevel ridge will amplify across the
central/southern MS valley. A stagnant airmass is expected with
daytime highs in the upper 90s/near 100 degrees. Otherwise, the
nocturnal LLJ is expected across central/south-central KS each night
and could result in isolated storm development, especially towards
sunrise each morning. A weak cold front will approach the area by
late week and may provide some relief from the hot temperatures.

.AVIATION /18Z TAFS THROUGH 18Z MONDAY/...
Issued at 1233 PM CDT Sun Jul 20 2025

A few showers and storms continue to develop near I-70 early
this afternoon along a remnant outflow boundary. Additional
development will be possible along this corridor through the
evening hours. Confidence on a direct impact to a terminal
remains too low at this time to include a mention in any TAF
however SLN, RSL, and GBD would have the highest probability of
seeing storms. Any storm that develops will be capable of
producing gusty and erratic winds, frequent lightning, and heavy
rainfall which will limit visibility. Surface winds will remain
breezy out of the south through around sunset before surface
winds will diminish. However, winds around 1,000 ft AGL will
increase to around 40 kts this evening leading to LLWS at RSL,
SLN, GBD, and HUT through tomorrow morning. Outside of any
thunderstorms, conditions will remain VFR through this TAF
period.
