Areas affected...Central and Eastern Nebraska...Far Northern
Kansas...Western Iowa

Concerning...Severe Thunderstorm Watch 294...297...

Valid 240338Z - 240545Z

The severe weather threat for Severe Thunderstorm Watch 294, 297
continues.

SUMMARY...The wind-damage threat will likely increase as a linear
MCS organizes across central and eastern Nebraska over the next
couple of hours. The severe threat should eventually affect parts of
western Iowa, where additional watch issuance may be needed during
the overnight period.

DISCUSSION...Mosaic radar imagery currently shows a developing line
of strong to severe thunderstorms from far northwest Kansas into
central and northeast Nebraska. This line is forecast to begin to
accelerate eastward across central and eastern Nebraska over the
next couple of hours, as a strengthening low-level jet increases
moisture and instability across the central Plains. As the storms
move eastward along a west-northwest to east-southeast gradient of
moderate to strong instability, the MCS is expected to become
increasingly organized. A wind-damage threat will be possible with
the stronger parts of the line, and this threat should become more
widespread as a large-scale bowing line segment organizes. The
wind-damage threat will affect much of eastern Nebraska late this
evening, and may affect western Iowa well after midnight.
