CONCERNING...SEVERE THUNDERSTORM WATCH 594...

VALID 140026Z - 140200Z

SEVERE THREAT WILL GRADUALLY DIMINISH WITHIN WS 594 THIS EVENING.

EVOLUTION OF A SWD-PROPAGATING MCS IS EVIDENT WELL SE OF THE WW THIS
EVENING.  THERE HAS BEEN RENEWED DEVELOPMENT ATOP THE COLD POOL
ACROSS PORTIONS OF CNTRL-ECNTRL NEB AND WCNTRL IA RECENTLY...POSING
PRIMARILY A LARGE HAIL THREAT. FARTHER W...A NARROW RIBBON OF
INSTABILITY EXISTS BETWEEN WRN PERIPHERY OF THE COLD POOL AND AHEAD
OF A LEE TROUGH.  VSBL SATL IMAGERY SUGGESTS THAT CU WITHIN THIS
ZONE ARE NOT GROWING SUBSTANTIALLY...PRESUMABLY GIVEN AN INCREASE IN
CINH.  IT IS POSSIBLE THAT TSTMS OVER CNTRL MN MAY BACKBUILD SWWD
INTO NRN PORTIONS OF THE WW THROUGH MID-EVENING...BUT THE
PROBABILITIES OF THIS OCCURRING SHOULD DECREASE AS PRIMARY LLJ
FOCUSES FARTHER S AHEAD OF THE MCS OVER NRN MO/NERN KS BY LATE
EVENING.
