.DISCUSSION...
Issued at 206 PM CDT Sun Sep 7 2025
Water vapor satellite this afternoon shows a strong upper trough
exiting eastward across the Great Lakes region along with am upper
ridge building across the southwestern CONUS. The central plains
reside underneath a weak northwesterly flow regime, and a subtle
ripple in this flow is located across the central Rockies and will
slowly approach the region late tonight through Monday afternoon.
There is already a bit surface response to increased winds aloft
over the Rockies as surface pressures have started to fall across
the High Plains. This will continue tonight and throughout the day
on Monday leaving a tight pressure gradient across the area, and
promoting breezy southerly winds. Some locations across central
Kansas could see wind gusts around 30-35 mph Monday afternoon.
Additionally, with the ridge building across the southwesterly
CONUS, warmer mid-level temperatures are forecast to creep their way
back over the central plains. As a result of this subtle mid-level
WAA set to begin overnight tonight, chances for some pesky widely
scattered showers and storms have been introduced into the forecast
beginning generally after midnight tonight. Coverage of this
activity is a bit uncertain, but PoPs for areas along and west of
the Flint Hills are generally around 20-30% late tonight into Monday
morning. This activity should generally wane through the late
morning hours on Monday, but additional shower and storm development
is possible Monday afternoon within the vicinity of I-135 and the
Kansas Turnpike. There`s some uncertainty in the coverage and
intensity of the activity Monday afternoon through Tuesday morning.
The main wrench in the forecast is the main axis of instability
(western Kansas) is likely to be somewhat offset from the better
forcing for ascent (central/eastern Kansas). There could be some
overlap across central Kansas where shear and instability are
better, and a strong to marginally severe storm cannot be ruled out
if the ingredients come together Monday afternoon and evening. With
the loss of diurnal heating, the intensity of any ongoing
activity should wane by Monday night, and leftover showers and
storms may possibly fester across eastern Kansas through Tuesday
morning.
With the mid/upper ridge axis continuing the build into the central
plains on Tuesday, this will likely cap off any additional
convection Tuesday afternoon, and should help to stave off most rain
chances for the rest of the week (more on this soon). In addition,
temperatures should warm back up closer to normal for this time of
year with highs in the mid 80s and lows in the mid 60s through the
remainder of the week. Moving ahead towards the middle and latter
portions of the week, some of the mid/long range models are hinting
that the mid/upper ridge forecast to build across the region will be
somewhat weaker than previously indicated. As such, there is a small
(under 20%) chance of locations along and north of I-70 seeing some
shower and storm activity Wednesday night into Thursday morning, as
well as this weekend as subtle perturbations in the flow round the
top the ridge axis. With that being said, most locations can expect
to remain dry after Tuesday.

.AVIATION /18Z TAFS THROUGH 18Z MONDAY/...
Issued at 1220 PM CDT Sun Sep 7 2025
Showers and a few storms will be possible in central KS after
08-09Z possibly spreading into parts of south central KS during
the morning hours on Monday. Some MVFR cigs will be hard to rule
out under the heavier activity. Breezy southerly winds will
also develop for areas along and west of the Flint Hills as we
move through the day on Monday.
