Key Message:

- Scattered showers with embedded thunderstorms expected this
evening, primarily across east central Kansas into western and
central Missouri.

Regional radar composite continues to show an increase in returns
early this afternoon across central and eastern Kansas, and
expect this trend to continue through the evening as increasing
deep layer ascent moves into the central Plains ahead of the next
upper wave. Highest probability of rain will be focused across
the southeast half of the CWA, with the 6pm-midnight timeframe as
the period with the most robust activity. A few embedded
thunderstorms will be possible within the scattered showers,
although severe weather is unlikely. Rainfall totals across
portions of east central Kansas into central Missouri will be
highest, with up to an inch of rain possible. Do not anticipate
any flooding at this time based on the latest MBRFC guidance.

Rainfall will end from west to east Saturday morning, clearing the
CWA prior to noon Saturday. Skies will clear by the afternoon with
highs warming into the middle 60s. Surface ridge settles in Saturday
night, and can't completely rule out some patchy fog across the
southern CWA. More notable warming and moisture transport is
expected Sunday into Tuesday, as an upper level ridge will build
into the central CONUS ahead of the next highly amplified wave. With
the approach of the upper trough, the next chance for thunderstorms
is expected on Tuesday evening/night. A few of the storms across
eastern Kansas may be strong, but uncertainty remains with respect
to convective organization/maintenance as instability wanes with
eastward extent/time.
