    Areas affected...Southeastern Nebraska and far northern Kansas

    Concerning...Severe potential...Watch unlikely=20

    Valid 251801Z - 252000Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Scattered strong to severe thunderstorms will continue to
    move east-northeastward across southern and southeastern NE this
    afternoon. Hail up to the size of 1" may accompany the strongest
    updrafts.

    DISCUSSION...Radar imagery early this afternoon shows an increase in
    moist convection developing along and ahead of a cold front
    extending north-northeast to south-southwest across portions of
    central and southern NE. Convergence along this boundary, in
    addition to a subtle mid-level shortwave perturbation, are resulting
    in enhanced lift across this region. Although surface based
    instability is limited, an elevated warm layer and cold temperatures
    above it in the mid to upper levels are contributing to MUCAPE
    around 500-1000 J/kg. Effective deep layer shear through this
    afternoon near 30-40 kt will continue to support some organization
    within the cluster of thunderstorms.

    With some additional, slow destabilization expected throughout the
    afternoon a few of the more robust updrafts will be capable of
    producing hail up to 1". However, the overall severe threat should
    remain low/isolated given the aforementioned environment and
    relatively poor mid-level lapse rates. A watch is not anticipated at
    this time.
