0245 PM CDT MON AUG 30 2010
AREAS AFFECTED...PARTS OF CENTRAL/NERN NEB AND CENTRAL/ERN SD
CONCERNING...SEVERE POTENTIAL...WATCH LIKELY
VALID 301945Z - 302015Z
WW WILL BE NEEDED SOON ACROSS PARTS OF CENTRAL/NERN NEB INTO
CENTRAL/ERN SD.
CAPPING INVERSION ACROSS THE PLAINS HAS INHIBITED STRONGER UPDRAFTS
FROM FORMING THUS FAR THIS AFTERNOON. HOWEVER...REGIONAL RADAR
IMAGERY INDICATED AN INCREASE IN CONVECTIVE ELEMENTS /WITH ISOLATED
LIGHTNING OVER NWRN KS/ ALONG ERN PERIPHERY OF A CLOUD SHIELD WHICH
EXTENDED FROM NWRN KS INTO CENTRAL SD. AIR MASS E OF THIS
CONVECTION IS MODERATELY UNSTABLE WITH INCREASING DEEP LAYER SHEAR
AS A PAIR OF MIDLEVEL IMPULSES TRACK NEWD ACROSS THE CENTRAL/NRN
PLAINS THIS AFTERNOON/EVENING. ADDITIONAL SURFACE HEATING /INTO
UPPER 80S AND LOWER 90S/ WILL FURTHER DECREASE ANY REMAINING
INHIBITION TO SUPPORT AN INCREASE IN TSTM DEVELOPMENT. GIVEN DEGREE
OF INSTABILITY AND SHEAR...SUPERCELLS WILL BE POSSIBLE WITH HAIL AND
STRONG WIND GUSTS THE PRIMARY THREATS. HOWEVER...STRENGTHENING LLJ
INCREASING HODOGRAPH CURVATURE SHOULD ALSO SUPPORT AN ISOLATED
TORNADO THREAT.
