Areas affected...Central and Eastern Kansas

Concerning...Severe Thunderstorm Watch 583...

Valid 040820Z - 041015Z

The severe weather threat for Severe Thunderstorm Watch 583
continues.

SUMMARY...An isolated wind-damage threat will continue over the next
couple of hours, but should become more isolated with time. New
weather watch issuance is unlikely to the east of WW 583.

DISCUSSION...The latest radar imagery from Wichita shows an MCS over west-central Kansas extending northward into west-central Nebraska.
The MCS is tracking eastward along a east-to-west corridor of
moderate instability, Where the RAP is analyzing MLCAPE in the 1000
to 2000 J/kg range. Large-scale ascent, associated with a central
Plains shortwave trough, will likely keep storms going for most of
the night near the instability axis. RAP forecast soundings near the instability axis across central Kansas have 0-6 km shear in the 20
to 30 knot range. This, combined with strengthening low-level flow
should be enough for a marginal wind-damage threat this morning.
However, decreasing instability should make any severe threat very
isolated, especially towards daybreak.
