    Areas affected...Southeast Nebraska into south-central Iowa

    Concerning...Severe Thunderstorm Watch 310...

    Valid 110959Z - 111200Z

    The severe weather threat for Severe Thunderstorm Watch 310
    continues.

    SUMMARY...With an organizing MCV moving into southwest Iowa, the
    threat for strong/severe surface gusts is expected to increase.

    DISCUSSION...Velocity data from KOAX suggest that an MCV has
    recently developed centered east of Lincoln, NE. Observations from
    the past 1-2 hours have suggested that the low-level thermodynamic
    environment can support strong/severe surface gusts as gusts from
    50-70 mph have been measured from south-central into southeast
    Nebraska. This MCV is likely to continue east along the buoyancy
    gradient, supported by a 50-55 kt low-level jet. Strong/severe
    surface gusts will be more probable at least into southwest Iowa.
    Temperatures are slightly cooler in south-central Iowa, though
    theta-e advection will improve the environment by daybreak. Large
    hail will remain possible, but should be more spatially limited
    owing to a less favorable storm mode. A tornado or two is
    conditionally possible as well.
