Areas affected...Central into northeast Kansas

Concerning...Severe potential...Watch likely

Valid 141940Z - 142215Z

Probability of Watch Issuance...80 percent

SUMMARY...Severe storms are expected to form by 21-22Z over parts of
central Kansas, with increasing coverage by late afternoon and
evening into eastern Kansas and western Missouri. Large hail and
damaging winds will be the primary threats.

DISCUSSION...Visible imagery shows CU beginning to form along a
pre-frontal trough across central KS where a narrow plume of strong
heating persists. This area of heating lies just north of an
extensive midlevel moist plume extending from the TX Panhandle into
northeastern KS, also coincident with the western fringe of a 40 kt
low-level jet and acting as an effective warm front. Showers are
also beginning to consolidate into more intense cores within this
moist plume.

As the cold front continues to develop southeastward, storms should
form along it, and also invigorate the leading storms currently
extending from near Wichita to Kansas City. Initially, supercells
are possible, with long hodographs favoring damaging hail and winds.
As the front deepens with time, storms will consolidate into a
squall line, with strong shear oriented parallel to the boundary
possibly resulting in a QLCS.
