CONCERNING...SEVERE POTENTIAL...WATCH LIKELY
VALID 270151Z - 270315Z
WW WILL BE ISSUED SHORTLY AS STORMS SPREAD ESEWD ACROSS SD/NEB.
ISOLATED STORMS CONTINUE MOVING ESEWD OUT OF THE NRN HIGH PLAINS OF
ERN WY...TOWARD INCREASINGLY-UNSTABLE ENVIRONMENT NOW IN PLACE OVER
MUCH OF NEB/SD. ATTM...IT APPEARS THAT INCREASING LLJ SHOULD ALLOW
STORMS TO CONTINUE/EXPAND IN COVERAGE.
STRENGTHENING LLJ WILL ALSO RESULT IN AN INCREASE IN DEEP-LAYER
SHEAR...SUPPORTIVE OF ROTATING/SUPERCELL STORMS. ASSOCIATED THREAT
FOR LARGE HAIL AND DAMAGING WINDS EXPECTED TO SPREAD ACROSS THE
DISCUSSION AREA SUGGESTS THE NEED FOR WW ISSUANCE.
