...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR PARTS OF THE
MID-MISSOURI VALLEY INTO SOUTHEAST KANSAS AND CENTRAL MISSOURI...

...SUMMARY...
Severe storms remain possible this evening into parts of the
overnight in the Mid-Missouri Valley into the Flint Hills and
central Missouri. Damaging winds, large hail, and perhaps a tornado
or two are the expected risks.

...01Z Update...
Cumulus towers continue to develop along the I-80 corridor this
evening. Water vapor imagery shows a very subtle shortwave that may
allow a few storms to develop near the Missouri Valley. The Slight
risk has been expanded to account for this scenario. Farther south,
convective initiation is becoming more likely northeast of Wichita.
Large hail and severe winds are the main threats, but a tornado risk
will be present with storms that interact favorably with remnant
outflow in eastern Kansas/western Missouri. Additional severe storms
are ongoing near Sioux Falls. Large hail and a tornado risk (for the
next hour or two) are the main concerns along with isolated severe
gusts.
