   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 338
   CONTINUES.
   
   AN ISOLATED SEVERE THREAT MAY CONTINUE ESEWD ACROSS THE SRN PART OF
   WW 338 OVER THE NEXT FEW HOURS. HAIL SHOULD BE THE PRIMARY THREAT
   WITH THE ACTIVITY.
   
   THE CONVECTION IN SW NEB IS CURRENTLY LOCATED ABOUT 80-90 STATUTE
   MILES NORTH OF A COLD FRONT AND IS ASSOCIATED WITH A SMALLER-SCALE
   LOW-LEVEL JET ANALYZED BY THE RUC. LIFT FROM THE JET AND LARGE-SCALE
   ASCENT ASSOCIATED WITH AN APPROACHING SHORTWAVE TROUGH SHOULD
   SUPPORT THE STORMS ESEWD INTO FAR SRN NEB TONIGHT. THE STORMS ARE
   LOCATED ABOVE A COLD DOME IN A WEAKLY UNSTABLE BUT STRONGLY SHEARED
   ENVIRONMENT ACCORDING TO FORECAST SOUNDINGS. HAIL WILL BE POSSIBLE
   WITH AN ISOLATED THREAT FOR LARGE HAIL OVER THE NEXT FEW HOURS. AS
   THE CELLS APPROACH SERN NEB LATER TONIGHT AND GAIN ACCESS TO AN AXIS
   OF MODERATE INSTABILITY...THE SEVERE THREAT COULD INCREASE WITH
   LARGE HAIL AND ISOLATED WIND DAMAGE POSSIBLE.
