   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 611
   CONTINUES.
   
   COMPLEX CONVECTION SITUATION HA UNFOLDED ACROSS PARTS OF NORTH
   CENTRAL AND NERN KS.  THE SRN END OF A NORTH-SOUTH BOWING LINE OF
   SEVERE STORMS FROM SOUTH CENTRAL NEB INTO NORTH CENTRAL KS IS NOW
   MERGING WITH PRE-EXISTING STRONG/SEVERE STORMS OVER NRN KS.  IN
   ADDITION...THE LINE IS MOVING EWD INTO AN ENVIRONMENT THAT WAS
   MODIFIED BY EARLIER CONVECTION...AND IT IS UNCLEAR IF THE RAPID EWD
   BOWING ASSOCIATED WITH A WELL-DEFINED REAR INFLOW JET NOTED ON KUEX
   VWP WILL BE ABLE TO MAINTAIN ORGANIZED SEVERE THREAT AS IT MOVES EWD
   ACROSS NERN KS.  THIS AREA WILL BE MONITORED CLOSELY DURING THE NEXT
   30-40 MINUTES...AND EITHER A NEW WW AFTER WW 611 EXPIRES AT 06Z OR
   AN EXTENSION IN TIME TO WW 611 CAN BE CONSIDERED IF NECESSARY.
   
   TO THE SOUTH OF THE BOW ECHO SYSTEM...STORMS CONTINUE TO DEVELOP AND
   MERGE WITH EXISTING STORMS ALONG THE SRN EDGE OF WW 611 OR NRN PARTS
   OF WW 615.  SEVERE WIND GUSTS HAVE BEEN REPORTED AT RSL...BUT
   SIMILAR TO THE STORMS TO THE NORTH...IT IS UNCLEAR IF A SEVERE
   THREAT WILL PERSIST INTO WW 611 OWING TO THE MODIFIED THERMODYNAMIC
   ENVIRONMENT.  PRIMARY THREAT MAY EVOLVE INTO A HEAVY RAIN SCENARIO
   OVER NERN/EAST CENTRAL KS INTO THE EARLY MORNING HOURS.
