.DISCUSSION...
Issued at 128 PM CDT Sun Sep 22 2024

Satellite imagery today show the upper trof over the central
high plains making slow progress eastward. Cooler air with the
associated front has moved across much of the forecast area, but
enough lift remains to bring showers into the cooler air, with
highs holding in the 60s. As the drier air gets deeper from
north to south, showers will be relegated to the southern
counties, where they may redevelop into Monday as the last bit
of lift with the upper system moves through. Kept temperatures
on the cool side of the mean on Monday, with clouds likely slow
to clear. Once they do, with light winds Monday night and
recent rain, could see some fog or haze in low spots with near
normal lows in the 50s.

Another clipper of sorts drops southward across the area on
Tuesday into Wednesday, and with the upper low right overhead,
may be enough instability to generate showers and possibly a
rumble of thunder before quickly moving south. This should keep
us on the subsident dry side for Wednesday with highs once again
in the 70s.

The forecast beyond Wednesday is highly variable and will likely
continue to be, as several features interact and impact each
other through the period. GFS and EC suggest the low that
clipped us Tuesday is stalled just to the south, then
retrograded back westward by a tropical system that is
forecast to develop in the gulf. This would have the potential
to draw moisture back westward into our area for anytime between
late Thursday and through the weekend. There are also timing
differences in the upper trof that comes in out of the northern
tier to usher these systems eastward. For now, most ensemble
guidance indicates near to slightly below normal temperatures
and increased chances for rain.

.AVIATION /18Z TAFS THROUGH 18Z MONDAY/...
Issued at 1241 PM CDT Sun Sep 22 2024

Biggest concerns for TAF sites this morning has been low cigs
holding in IFR range. Upper system will slowly move eastward and
improve cig heights, becoming MVFR mid afternoon and lifting to
VFR by this evening. Added a few hours of showers to MHK as next
batch of light rain moves through into mid day. Could see some
showers near TOP/FOE in the early morning hours on Monday but
would have less impact on ceilings than today.

.TOP WATCHES/WARNINGS/ADVISORIES...
