Day 1 Convective Outlook

Valid 180100Z - 181200Z

....THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER PARTS OF THE
SOUTH-CENTRAL HIGH PLAINS...

....SUMMARY...
Isolated severe thunderstorms remain possible across parts of the
south-central High Plains, with hail and localized severe gust
potential.

....South-central High Plains...
Scattered strong to severe cells with hail potential currently
extend from the Colorado Springs area southeastward into the
northwest TX Panhandle. Cool midlevel temperatures as well as
easterly low-level winds veering to westerly aloft are supporting
the cellular storm mode with longevity.

Height falls with the weak upper trough will continue overnight, and
southerly winds around 850 mb may support weak theta-e advection for
a few hours this evening. Given substantial instability noted on the
00Z DDC sounding, an isolated hail threat may eventually develop
from the west.

Elsewhere, a cluster of storms persists over south-central KS near
the OK border, and near a warm front. Isolated hail or wind may
persist in this area as well, and perhaps affect the rest of
south-central KS later this evening with marginal hail.
