    Areas affected...North-central and Northeast Kansas...Far Southeast Nebraska...Southwest Iowa...Far Northwest Missouri

    Concerning...Severe Thunderstorm Watch 449...452...

    Valid 040216Z - 040415Z

    The severe weather threat for Severe Thunderstorm Watch 449, 452
    continues.

    SUMMARY...Severe wind gusts and isolated large hail will continue to
    be possible over the next few hours from parts of north-central
    Kansas northeastward into southwest Iowa. A watch extension in area
    may be needed to the south and east of the current watches.

    DISCUSSION...A broken line of strong to severe thunderstorms is
    ongoing near an axis of strong instability, where surface dewpoints
    range from the upper 60s to the mid 70s F. Across this moist
    airmass, the RAP shows an axis of instability with MLCAPE in the
    3500 to 4500 J/kg range. The instability along with large-scale
    ascent associated with a mid-level shortwave trough is helping to
    maintain storm intensity within the line. The line will move slowly southeastward into northeast Kansas, far northwest Missouri and
    southwest Iowa over the next few hours. Although a severe threat is
    expected to continue through late this evening, the threat could
    become a bit more isolated as inhibition gradually increases.
