Areas affected...far southeastern Nebraska/northwestern
Missouri/northeastern Kansas

Concerning...Severe Thunderstorm Watch 363...

Valid 100621Z - 100745Z

The severe weather threat for Severe Thunderstorm Watch 363
continues.

SUMMARY...A local increase in damaging wind risk is apparent across
northeastern Kansas/northwestern Missouri.

DISCUSSION...Latest radar loop shows a north-south cluster of storms
moving across southeastern Nebraska and northwestern Kansas, with a
more southwest-to-northeast extension of the band into southwestern
Iowa.  Latest radar loop shows a rapid southward surge of this Iowa
convection toward/into northwestern Missouri, at speeds in excess of
70 kt.  WIth a very unstable airmass in advance of this convection
(mixed-layer CAPE in excess of 3000 J/kg per RUC-based objective
analysis), and low-level ascent maximized due to warm advection
associated with the west-southwesterly low-level jet, expect this
convection to persist, spreading into the Topeka and Kansas City
metro areas over the next hour to hour and a half.  Damaging winds
-- possibly in excess of 70 MPH locally, may occur.
