.DISCUSSION...
Issued at 336 AM CDT Sun Aug 31 2025

Water vapor imagery indicated an elongated trough extending from
northwest South Dakota into northeast Nebraska.  Lift ahead of this
disturbance is leading to light to moderate showers across eastern
Kansas into far western Missouri, though easterly flow emanating
from surface ridge in the Great Lakes region is eating away at
precipitation potential farther east.

For today, looking at additional waves of light rain across eastern
Kansas into western Missouri.  The clouds and periodic precipitation
will keep diurnal temperatures well below seasonal norms.
Instability will be very limited so only expect a sporadic
lightning strike or two throughout the day. While showers will be
relatively slow moving, precipitable water values will only be
slightly elevated ~1.5 inches so am not expecting any hydrology
concerns with rainfall amounts near 1 inch (~60 percent HREF
ensemble probability) in eastern Kansas through Tuesday with lesser
amounts farther east.

As upper level wave builds southeast isentropic lift increases
towards 06Z-12Z Monday south of highway 36 and mainly west of
highway 65.  Both the NAM and GFS show deeper saturation developing,
though the NAM keeps the saturation closer to the surface layer
while the GFS is closer to the 800-600 mb layer. Regardless of which
solution you believe, instability looks to be limited but could see
a increased precipitation potential Monday morning.  Lift wanes as
upper level wave approaches and moves south of the region on Monday.
 Atmospheric column dries out from aloft bringing an end to
meaningful precipitation, but still could see the potential for
drizzle lingering into Tuesday with low lying stratus lingering.

Models are still continuing to suggest a strong cold front diving
south across the Midwest mid-week, but models have trended a bit
slower suggesting the cooler air would arrive Wednesday night. This
will keep temperatures unseasonably cool on Thursday, before
temperatures moderate into the weekend. Along and ahead of the
front, there is the chance for additional shower and thunderstorms.
While speed shear increases in the column, low level moisture and
resulting instability remain limited keeping the severe weather
potential to a minimum.

.AVIATION /06Z TAFS THROUGH 06Z MONDAY/...
Issued at 1151 PM CDT Sat Aug 30 2025

Scattered light showers continue across the region, with this
likely continuing through the overnight hours into Sunday
morning. There may be periods of a bit more moderate rainfall
with VIS reductions to MVFR between roughly 10z and 16z at STJ
and 12z and 18z at the KC metro terminals, so have gone with
PROB30 groups accordingly for those periods. Isolated showers
may linger in the vicinity of the terminals into Sunday
afternoon and evening, but for now have kept the TAF dry during
this time.
