.DISCUSSION...
Issued at 210 PM CDT Mon Oct 6 2025

Water vapor imagery this afternoon displays a broad, positively
tilted mid- to upper-level trough extending from central Canada into
the northern Plains. This feature has driven a slow-moving cold
front southeastward over the past 24 hours. As of 1 PM, surface
analysis places the front from northeast KS into northwest MO.
Behind the front, scattered showers continue as a shortwave
disturbance pivots across the region. The post-frontal airmass,
along with lingering cloud cover and precipitation, has kept
afternoon highs seasonably cool, generally in the mid to upper
50s. These high temperatures are nearly 30 degrees cooler than
temperatures across the area 48 hours ago. Elevated instability
will bring the chance for a few rumbles of thunder this
afternoon, particularly south of Interstate-80.

Shower activity will gradually diminish from north to south through
the evening and early overnight period. Observed rainfall totals
over the past 24 hours range from 0.50" along Interstate-80,
increasing to 2-3 inches in southeast NE and southwest IA.
Additional rainfall totals are expected to peak around 0.15".

Overnight lows will likely be the coolest of the week, dipping into
the low 40s. Patchy fog may develop early Tuesday morning, as light
winds and residual low-level moisture promote favorable conditions.
Skies will gradually clear on Tuesday as upper-level ridging begins
to build across the central and southern Plains. At the surface,
high pressure will settle into the area, bringing a warming trend
through the remainder of the week. Highs will climb into the upper
60s to low 70s on Tuesday and Wednesday, with mid to upper 70s
expected Thursday and Friday. Overnight lows will generally stay in
the mid 50s.

A weak shortwave disturbance is expected to pass through the region
on Thursday. However, limited moisture will keep precipitation
chances low, with PoPs topping out near 15-20%. Temperatures may
reach the low 80s by the weekend, ahead of another upper-level
trough that is forecast to push into the region later Sunday into
next week. This system is expected to bring cooler temperatures and
renewed chances for precipitation (PoPs 15-30%).

.AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/...
Issued at 607 PM CDT Mon Oct 6 2025

Widely scattered showers are in the process of shifting east of
the terminal locations as of 23z, with the northern edge of MVFR
ceilings currently located just to the north of KOMA. This
forecast update will indicate prevailing VFR conditions at KOFK,
and a transition from MVFR to VFR by 07/02z at KOMA, and by
07/04z at KLNK. Winds will remain light from the north, and
current thinking is that lingering cloudiness overnight and the
influx of drier air from the north will limit fog potential.
