   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 534 CONTINUES.

   SUMMARY...MONITORING FOR A POTENTIAL EXTENSION OF THE TORNADO RISK
   TO THE N OF WW 354 AS THE WARM SECTOR HAS BACKED WEST INTO PARTS OF
   THE OMAHA METRO AREA.

   DISCUSSION...SUPERCELL NOW INTO CASS COUNTY IN SERN NEB AS OF 1830Z
   APPEARS TO BE JUST AHEAD OF A 993 MB CYCLONE NEAR THE SERN NEB/NERN
   KS BORDER. THE QUASI-STATIONARY FRONT THAT THE SURFACE LOW WILL
   TRACK ALONG THIS AFTERNOON HAS BACKED SLIGHTLY WWD OVER THE PAST
   HOUR AND APPEARS TO BE BISECTING PORTIONS OF THE OMAHA METRO AREA.
   IT IS PLAUSIBLE THAT THIS SUPERCELL AND/OR ADDITIONAL STORMS TO THE
   N MAY MAINTAIN SURFACE-BASED CHARACTER AS THEY AFFECT PORTIONS OF
   SARPY/DOUGLAS COUNTIES IN NEB AND MONONA COUNTY IA THROUGH 21Z.
