   CORRECTED FOR INTERSTATE NUMBER REFERENCED IN TEXT
   
   THUNDERSTORM DEVELOPMENT WILL CONTINUE TO INCREASE ACROSS THIS AREA
   OVERNIGHT ALONG NOSE OF DEVELOPING SLY LLJ.  STRONGER CORES WILL
   REMAIN CAPABLE OF ISOLATED LARGE HAIL.  HOWEVER...OVERALL
   INTENSITY/COVERAGE OF ANY EXPECTED SEVERE THREAT DOES NOT APPEAR TO
   WARRANT WW ATTM.  WILL CONTINUE TO MONITOR.
   
   THUNDERSTORMS HAVE INTENSIFIED QUICKLY ALONG AND NORTH OF STATIONARY
   SURFACE FRONT NOW EXTENDING FROM CENTRAL IA ROUGHLY WWD JUST NORTH
   OF I-80 INTO CENTRAL NEB.  FORECAST SOUNDINGS INDICATE ENVIRONMENT
   REMAINS CHARACTERIZED BY RELATIVELY STEEP MID LEVEL LAPSE RATES AND
   EFFECTIVE BULK SHEAR AROUND 40-45 KT.  STORMS WILL BE MORE LIKELY
   NORTH OF THE FRONT...THOUGH ISENTROPIC LIFT MAY BE SUFFICIENT FOR
   ELEVATED STORMS INCREASING SOUTH OF THE SURFACE FRONT INTO SRN
   NEB/NRN KS OVER THE NEXT FEW HOURS.
   
   THOUGH ACTIVITY WILL REMAIN ELEVATED...FEED OF LOW LEVEL MOISTURE
   WILL BE SUFFICIENT FOR MODERATE MUCAPE / I.E. ELEVATED CAPE FROM
   1500-2500 J/KG /.  GIVEN STEEP LAPSE RATES AND AMOUNT OF SHEAR...
   ISOLATED CORES MAY DEVELOP ROTATION AND INCREASE THE POTENTIAL FOR
   MARGINALLY SEVERE HAIL.  ATTM...EXPECT RESULTANT SEVERE THREAT WILL
   REMAIN TOO LIMITED IN COVERAGE/INTENSITY TO WARRANT NIGHTTIME SEVERE
   THUNDERSTORM WATCH.  HOWEVER...WILL CONTINUE TO MONITOR EVOLUTION OF
   THIS ACTIVITY.
