    Concerning...Severe Thunderstorm Watch 243...

    Valid 250148Z - 250315Z

    The severe weather threat for Severe Thunderstorm Watch 243
    continues.

    SUMMARY...Large-hail potential is expected to become more isolated
    through 04z.

    DISCUSSION...Recent radar and satellite trends indicate warming
    cloud tops and lowering reflectivity cores, which coincides with the
    gradual cooling and stabilization of the boundary layer. However,
    plan-view VWP data and short-term model forecasts indicate the
    strengthening of a nocturnal low-level jet from south-central NE
    into southeast SD. Enhanced convergence and moist flux within the
    terminus of that feature may support the continuation of isolated,
    strong to severe storms in far southeast SD and northwest IA for the
    next hour or two. Elsewhere, expect a gradual decrease in storm
    coverage and intensity through 04z as convective inhibition
    continues to increase.
