.DISCUSSION...
Issued at 227 PM CDT Wed Apr 23 2025

Remnants of yesterday's surface boundary in northern KS, combined
with a subtle mid-level wave and some isentropic ascent led to the
development of scattered convection in the area by midday today.
Instability has been increasing this afternoon as temperatures
warm and boundary layer moisture increases. Shear has been very
weak, so storms have had a tendency to develop quickly, then
remain fairly stationary as they produce heavy rain and some
hail. Various outflow boundaries will now also act as areas of
lift as shear and instability continue to increase. Thus,
scattered storms will remain in the forecast into this evening.
Large hail, damaging wind gusts and localized flash flooding
will be possible with the strongest storms.

Have POPs continuing into the overnight period, with the higher
probabilities across northern sections of KS as another weak shortwave
and associated vort max ride through the southwest flow aloft. There
could be a break in precipitation Thursday morning and midday before
a more obvious mid-level wave and a surface cold front move across
the area late in the day. With that, another round of scattered
convection is expected to develop. If after dark, instability will
be a bit more limited and the severe risk will not be as high.
Flooding might be one of the more concerning hazards, especially if
rain falls in areas that are already saturated from recent rainfall.

Surface high pressure will start to work into the area behind
Thursday night's cold front, and a upper ridge will build aloft on
Friday. So a brief dry stretch of weather is expected Friday
afternoon through much of the day Saturday. Temperatures will
top out in the 60s during that timeframe with the cooler air
mass in place. Have POPs increasing again on Sunday as a WAA
pattern sets up ahead of an approaching longwave trough axis
west of the region. The threat for severe weather could increase
once again when that trough nears KS on Monday, depending on
the timing of the surface front and associated instability axis.

.AVIATION /18Z TAFS THROUGH 18Z THURSDAY/...
Issued at 1230 PM CDT Wed Apr 23 2025

Scattered storms are developing at midday around the area. Given
the scattered nature, confidence is not high in whether storms
will directly impact airports and the timing. Thus, have kept a
mention of PROB30 for a few hours this afternoon and early this
evening. Will monitor radar and amend if necessary. Chances
decrease later this evening but will increase again toward the
end of the 18Z TAF period.
