Areas affected...portions of central and southeastern KS

Concerning...Severe Thunderstorm Watch 390...

Valid 042314Z - 050045Z

The severe weather threat for Severe Thunderstorm Watch 390
continues.

SUMMARY...Upscale growth of ongoing thunderstorms appears likely
this evening. Damaging winds and isolated hail are possible. A new
downstream watch or an extension of WW390 will likely be needed in a
couple of hours.

DISCUSSION...As of 23UTC, a cluster of severe thunderstorms was
ongoing over central KS with additional development occurring along
the cold front to the west. The environment ahead of these storms
remains favorable for damaging winds and hail with a broad warm
sector, large buoyancy and sufficient deep-layer shear for storm
organization. Thus far, storms have remained ahead of the front, but
with the front starting to surge southeast, additional development
and upscale growth appears likely over the next couple of hours.
Large precipitable water values above 1.5 inches will support strong
water and hail loaded downdrafts as storms merge. Several measured
severe gusts have already occurred suggesting the environment is
likely to remain favorable for damaging gusts this evening,
especially as stronger cold pools develop. Hi-res guidance shows
upscale growth into one or more clusters and eventually a line is
likely as storms move east/southeast toward the OK border. As the
severe threat is likely to persist into this evening, a new
downstream watch or extension of WW390 may need to be considered in
the next couple of hours.
