...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS FOR PORTIONS OF
SOUTHERN/CENTRAL KANSAS...

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR NORTH-CENTRAL
SOUTH DAKOTA AND SOUTHERN NORTH DAKOTA...

...SUMMARY...
Severe thunderstorms capable of widespread damaging winds and large
hail are expected to persist this evening across portions of
southern/eastern Kansas and northern Oklahoma.

...Central Plains...
2 storms clusters have now congealed into a large line of storms
across central and southern Kansas. This line of storms has a
history of producing 75 to 100 mph winds earlier this evening. While
the extreme wind threat is likely over, 70-80 mph winds are still
possible for a few more hours as this squall line moves east across
southeast Kansas with some wind threat expected to persist into
Missouri during the overnight period. See MCD 842 for additional
information.

Farther south, a persistent, large supercell continues across
western Oklahoma. This supercell has a history of baseball sized
hail and at least one tornado. This storm will encounter increasing
inhibition as the boundary layer continues to cool ahead of it. The
HRRR suggests additional supercells may develop across
northwest/northern Oklahoma late this evening along the trailing
outflow boundary from the Kansas MCS as the low-level jet
strengthens. These storms will have primary threats of large hail
and severe wind gusts, although a tornado or two may also be
possible.

...Dakotas...
A cluster of storms produced a swath of damaging wind gusts across
western South Dakota this afternoon and early evening. This threat
has mostly abated, but additional supercells have developed near the
ND/SD border which will pose a threat of damaging winds and large
hail for a few more hours this evening. For more information, see
MCD 841.
