Areas affected...Parts of eastern NE into western IA
Concerning...Severe Thunderstorm Watch 434...
Valid 182251Z - 190015Z
The severe weather threat for Severe Thunderstorm Watch 434
continues.
SUMMARY...The threat for severe gusts and isolated hail will
continue into this evening.
DISCUSSION...An extensive thunderstorm band is ongoing from
northwest IA into eastern NE. There has been a tendency for these
storms to be slightly anafrontal, due to generally front-parallel
deep-layer flow and only marginal deep-layer shear. However, a few
embedded clusters have begun to accelerate eastward and keep pace
with the front, which could result in an increasing threat of strong
to severe gusts as storms approach the Omaha/Lincoln areas and move
into a larger portion of northwest IA. Otherwise, moderate to strong
buoyancy will support potential for isolated hail with the strongest
embedded cells.
