The severe weather threat for Severe Thunderstorm Watch 444
continues.
SUMMARY...Severe hail and damaging wind gusts remain possible across
central KS for at least the next hour.
DISCUSSION...Long-lived supercell currently moving through Rush,
Pawnee, and Barton counties continues to show radar signatures
consistent with severe hail. Outflow from the late morning/early
afternoon storms stabilized much of southwest KS (roughly from Pratt
and Medicine Lodge westward) but favorable low-level moisture (i.e.
dewpoints in the upper 60s/low 70s) and wind profiles exist downwind
of the ongoing supercell. As a result, the downstream airmass is
quite favorable for storm persistence. However, recent radar scans
the storm has shown a bit more development on its western flank,
which could contribute to a more southerly storm motion. If the more
southerly storm motion is realized, the storm will interact with new
development occurring within the WAA over the outflow in southwest
KS more quickly. This interaction and propagation into a less
unstable airmass would likely lead to quick storm weakening. A more
southeasterly storm motion would lead to longer storm longevity. In
either case, severe hail and damaging wing gusts are possible for
the at least the next hour across central KS.
