AREAS AFFECTED...NCNTRL NEB TO SCNTRL ND
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 082206Z - 082300Z
CU FIELD IS GRADUALLY EXPANDING/DEEPENING WITHIN POST DRYLINE
ENVIRONMENT ACROSS THE NEB PANHANDLE. THIS CONVECTION IS INDICATIVE
OF THE VERY STEEP LAPSE RATES IN PLACE ACROSS THE CNTRL HIGH PLAINS
WHERE SFC TEMPERATURES HAVE WARMED INTO THE MID 80S. LATEST
THINKING IS SUSTAINED CONVERGENCE ALONG THE DRYLINE SHOULD PROVE
FAVORABLE FOR ENCOURAGING SUSTAINED DEEP UPDRAFTS/TSTMS BY 00Z-02Z.
GIVEN THE VERY UNSTABLE AIRMASS IN PLACE ANY STORMS THAT DEVELOP
WILL LIKELY PRODUCE VERY LARGE HAIL...IN ADDITION TO ISOLATED
TORNADOES WITH EARLY SUPERCELL ACTIVITY.
