.DISCUSSION...
Issued at 252 AM CDT Mon Sep 23 2024

Upper trough was moving east into central and western Kansas early
this morning with scattered showers over the southeastern quarter of
Kansas. Cloud cover remains persistent over much of the local area
with temperatures still in the mid 50s to around 60 for most spots,
not much cooler than Sunday afternoon values. The trough finally
passes early this evening, taking a somewhat more neutral tilt
through the day. This should continue to bring some light showers to
east-central Kansas into the early afternoon with significant
moisture depths decreasing by late afternoon. Instability may be just
enough for a few thunderstorms in this activity. Clouds will still
be enough to keep highs in eastern areas in the 60s with 70s in some
clearing in the west.

Clearing overspreads the bulk of the area tonight but clouds
increase overnight as an upper wave digs southeast into the upper
and middle Mississippi Valley. Weak high falls locally combining
with increasing mid level lapse rates produces minor instability
and chances for weak convection supported by warmer highs.

A dry period continues to be expected for Tuesday night into early
Thursday as the upper trough settles into the southern Mississippi
Valley. The track and speed of this and a potential tropical system
are quite uncertain for the late week and weekend, but there has
been some suggestion of remnants of the latter rotating around the
former and impacting the region. NBM PoPs have trended toward this
solution though confidence in this occurring is limited. Temperatures
for these periods should remain fairly close to late September
normals.

.AVIATION /18Z TAFS THROUGH 18Z TUESDAY/...
Issued at 1227 PM CDT Mon Sep 23 2024

VFR at all TAF sites through the TAF period. A VFR cloud deck
will hang tough through the day and into the evening. A cold
front will move through tomorrow late morning to early afternoon
and may bring some rain or even an isolated thunderstorm to the
area, but confidence in coverage and timing is too low at this
time to mention in the TAF.

.TOP WATCHES/WARNINGS/ADVISORIES...
None.
