SPC MESOSCALE DISCUSSION 1627 FOR NCNTRL NEB...CNTRL SD AND
   SCNTRL/SERN ND
   CONCERNING...SEVERE THUNDERSTORM POTENTIAL...
   
   VALID 081616Z - 081900Z
   
   THUNDERSTORMS MAY INTENSIFY DURING THE NEXT FEW HOURS FROM CNTRL
   NEB NWD CNTRL SD AND INTO PARTS OF S CNTRL/SERN ND. PRIMARY THREAT
   SHOULD BE ISOLATED STRONG WIND GUSTS. A WW IS NOT ANTICIPATED AT
   THIS TIME...BUT AREA WILL CONTINUE TO BE MONITORED. A BETTER THREAT
   FOR SEVERE STORMS IS EXPECTED FROM NERN WY INTO PARTS OF WRN SD
   LATER THIS AFTERNOON.
   
   A SURFACE BOUNDARY EXTENDS FROM THE CNTRL DAKOTAS SWD THROUGH NWRN
   NEB. MORNING RAOB DATA SHOWED STEEP LAPSE RATES OVER THE AREA...AND
   THE ATMOSPHERE WILL BECOME MODERATELY UNSTABLE IN NARROW CORRIDOR
   ALONG MOIST AXIS JUST E OF THE BOUNDARY WITH MLCAPES FROM 2000 TO
   2500 J/KG. UPPER TROUGH OVER NRN ROCKIES IS EXPECTED TO REMAIN WELL
   W OF THE AREA DURING THE DAY. THIS WILL LIMIT MID LEVEL FLOW TO AOB
   25 KT...RESULTING IN WEAK DEEP LAYER SHEAR PROFILES. LOW LEVEL JET
   IS ALSO EXPECTED TO REMAIN VEERED TO SWLY AND MAY WEAKEN FURTHER AS
   MINOR LEAD SHORTWAVE LIFTS NEWD AWAY FROM AREA. HOWEVER...AS THE
   BOUNDARY LAYER CONTINUES TO WARM...LOW LEVEL THERMODYNAMIC PROFILES
   WILL BECOME MORE FAVORABLE FOR ISOLATED STRONG WIND GUSTS AS STORMS
   INTENSIFY BY MID-LATE AFTERNOON.
