Areas affected...Southern Kansas...Northern and Eastern Oklahoma

Concerning...Severe Thunderstorm Watch 339...340...

Valid 100756Z - 101000Z

The severe weather threat for Severe Thunderstorm Watch 339, 340
continues.

SUMMARY...A severe threat is expected to continue as cells move
southeastward from southeast Kansas into northern and eastern
Oklahoma. Wind damage and isolated large hail will be the main
threats. A local extension in area for parts of northeastern
Oklahoma between the two ongoing watches may be needed.

DISCUSSION...The latest mosaic radar imagery from southern Kansas
into east-central Oklahoma shows an MCS that is organizing in two
parts. The first part is in southeast Kansas along an
northwest-to-southeast gradient of instability, where the RAP has
MLCAPE in the 500 to 1500 J/kg range. The second is in central
Oklahoma, where a pocket of moderate to strong instability exists,
with the RAP estimating MLCAPE as great as 3000 J/kg. The two areas
of storms are expected to co*bine into one large MCS, with the
stronger part of the MCS moving southeastward across parts of
northeast and east-central Oklahoma. Although the severe threat will
continue within the ongoing watches, an extension in area between
the two watches may be needed for the developing severe threat in
northeast Oklahoma.
