   NEAR-TERM HAZARDS...BUT A TORNADO OR TWO IS ALSO POSSIBLE WITH
   SUPERCELLS PROGRESSING ALONG A REMNANT OUTFLOW BOUNDARY OVER THE NEB
   PANHANDLE. WITH TIME...UPSCALE GROWTH SHOULD FOSTER A PREDOMINANT
   WIND RISK TOWARDS THE NEB/CO/KS BORDER AREA.

   DISCUSSION...A FEW SUPERCELLS HAVE FORMED OVER THE WRN NEB PANHANDLE
   IN THE WAKE OF A LEAD SUPERCELL THAT DISSIPATED W OF LBF. WITH A
   REMNANT OUTFLOW BOUNDARY EVIDENT FROM NEAR IML TO BFF...THIS RENEWED
   DEVELOPMENT IS OCCURRING WITHIN A LOCALIZED ENVIRONMENT FAVORABLE
   FOR A SHORT-TERM TORNADO RISK GIVEN LOWERED LCLS AND ENHANCED
   LOW-LEVEL SRH. WITH TIME...TSTM AMALGAMATION SHOULD RENDER MORE
   PROGRESSIVE COLD POOL DEVELOPMENT AND TEMPER THE VERY LARGE HAIL
   RISK WHILE LEADING TO A MORE WIDESPREAD SEVERE WIND RISK. DOWNSTREAM
   WW ISSUANCE INTO PARTS OF THE WFO GLD AREA SEEMS PROBABLE BY 01-02Z.
