CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 041958Z - 042130Z

W CENTRAL TO N CENTRAL KS AREA IS BEING CONSIDERED FOR A SEVERE
THUNDERSTORM WATCH IN THE NEXT 30-60 MIN.

THUNDERSTORMS ARE FORMING E/NE OF A MID LEVEL VORT MAX OVER W
CENTRAL KS...INVOF A SW-NE ORIENTED BOUNDARY THAT TRAILS SWWD FROM
THE PRIMARY SYNOPTIC LOW IN NEB.  THOUGH AREAS S OF THIS BOUNDARY
ARE W OF THE DRYLINE IN THE DRY/DEEPLY MIXED BOUNDARY LAYER...A WRAP
AROUND FEED OF 50 DEW POINTS FROM THE N PERSISTS FROM ACROSS N
CENTRAL KS.  STRONG UPPER DIVERGENCE IN ADVANCE OF THE MID LEVEL
VORT MAX AND CONVERGENCE ALONG THE SURFACE BOUNDARY SHOULD SUPPORT
ADDITIONAL THUNDERSTORM DEVELOPMENT E/NEWD FROM W CENTRAL INTO N
CENTRAL KS THE NEXT 2-3 HOURS.	STEEP LAPSE RATES AND COOL MID LEVEL
TEMPERATURES WILL SUPPORT A THREAT OF LARGE HAIL AND STRONG
DOWNBURST WINDS WITH THE STRONGEST STORMS.
