.DISCUSSION...
Issued at 131 AM CDT Mon Aug 11 2025

Early this morning, a complex of thunderstorms continued to
develop and slowly push east northeast across southern Kansas.
This complex will make it into our area shortly. It appears the
heaviest rain will fall along and south of the I-35 corridor,
where around three inches of rain could fall. The storm complex
may make it as far north as I-70, but rain rates should be lower
to the north as the best instability and lift are likely to be
focused further south. Around 0.5-1.5 inches is the most likely
amount for the I-70 corridor. The heaviest rain should exit the
area shortly after sunrise. Scattered showers and thunderstorms
will be possible through Tuesday, more so across eastern Kansas
than central, as the upper-level trough doesn`t fully exit our
area until Tuesday night. With thick cloud cover today,
temperatures will likely struggle to reach the low 80s.
Temperatures will slowly rise through the week as an upper-level
ridge starts to build back into the area.

VFR to MVFR through the TAF period with off and on showers and
thunderstorms. The most likely time for thunderstorms to impact
the terminals is 11z to 15z. Before and after that timeframe
thunderstorms will likely be more scattered and confidence in
storms impacting terminals during the afternoon and evening is
much lower at this time. Wind will generally be light and out of
the southeast but may go variable several times through the
period.
