    Areas affected...parts of central and eastern
    Nebraska...southeastern South Dakota...and far western Iowa

    Concerning...Severe Thunderstorm Watch 306...

    Valid 240110Z - 240245Z

    The severe weather threat for Severe Thunderstorm Watch 306
    continues.

    SUMMARY...Storms increasing in coverage/intensity -- likely in
    response to the developing low-level jet -- suggest increasing
    severe potential over the next couple of hours. A new WW remains
    likely to be needed east of ongoing activity.

    DISCUSSION...After a brief decreasing trend in ongoing convection,
    storms have begun to increase in both coverage and intensity once
    again -- mainly across north-central Nebraska and into south-central
    and southeastern South Dakota. The convective uptick is apparently
    in response to increasing QG forcing, as a subtle feature aloft
    shifts into the Plains, along with associated/accompanying low-level
    jet increase. While low-level capping hindered more widespread
    diurnal surface-based activity, continued increases in slightly
    elevated but robust convection are expected. As convection shifts eastward/southeastward with time, a new WW east of WW 306 remains a
    likelihood this evening.
