    Areas affected...Much of eastern Nebraska

    Concerning...Severe Thunderstorm Watch 281...

    Valid 190221Z - 190415Z

    The severe weather threat for Severe Thunderstorm Watch 281
    continues.

    SUMMARY...A few storms capable of hail and locally strong wind gusts
    remain possible across eastern Nebraska. Isolated storms may
    eventually affect northern Kansas, but a watch may not be needed.

    DISCUSSION...Storms across NE has remained largely cellular this
    evening owing to lengthening hodographs and sufficient low-level
    SRH. 00Z soundings from the area indicate a marginally unstable
    environment with relatively poor lapse rates aloft, yet ample
    low-level moisture. Some increase in the southerly low-level jet
    this evening may support a continued severe threat over far southern
    NE and into northern KS, as capping remains minimal. However, it is
    unclear whether a new watch will need to be issued at this time,
    especially if storms remain isolated.
