   CORRECTED FOR GEOGRAPHIC REFERENCE
   
   WARM FRONT IS GRADUALLY LIFTING NWD ACROSS ERN NEB AND NWRN
   IA...CURRENTLY STRETCHING FROM NEAR OLU TO NEAR MCW.  STRONG HEATING
   ACROSS SCNTRL/SERN NEB HAS ALLOWED A SUBSTANTIAL CU FIELD TO EVOLVE
   WITHIN THE BOUNDARY LAYER...CLUSTERING NEAR THE WARM FRONT WHERE
   SEVERAL DEEPER UPDRAFTS MAY SOON FORM THUNDERSTORMS.  THERMODYNAMIC
   ENVIRONMENT IS QUITE FAVORABLE FOR SUPERCELLS WITH MLCAPE IN EXCESS
   OF 3000 J/KG.  INHIBITION WILL CONTINUE TO WEAKEN OVER THE NEXT
   ONE-TWO HOURS AND THUS SUPERCELLS SHOULD DEVELOP NEAR/ALONG THE WARM
   FRONT WHERE SHEAR WILL UNDOUBTEDLY ENHANCE THE POTENTIAL FOR
   TORNADOES AND VERY LARGE HAIL.
